Continuous-rotation servos are servos that do not have a limited travel angle, instead they can rotate continuously. They can be thought of as a motor and gearbox with servo input controls. In such servos the input pulse results in a rotational speed, and the typical 1.5 ms center value is the stop position. A smaller value should turn the servo clockwise and a higher one counterclockwise.

The number of channels (technically, servo channels) a plane has is normally determined by the number of mechanical servos that have been installed, with a few exceptions, such as the aileron servos, where two servos can operate via a single channel using a Y harness (with one of the two servos rotating in the opposite direction). On smaller models, usually one servo per control surface (or set of surfaces in the case of ailerons or a split elevator surface) is sufficient. Generally, for a plane to be considered fully functional, it must have four channels (elevator, rudder, throttle, and ailerons).
|
|
It receives and processes the signal from the transmitter, translating it into signals that are sent to the servos and speed controllers. The number of servos in a model determines the number of channels the radio must provide. Typically the transmitter multiplexes and modulates the signal into pulse-position modulation. The receiver demodulates and demultiplexes the signal and translates it into the special kind of pulse- width modulation used by standard RC servos and controllers.

If the servo position changes from that commanded, whether this is because the command changes, or because the servo is mechanically pushed from its set position, the error signal will re-appear and cause the motor to restore the servo output shaft to the position needed. Almost all modern servos are proportional servos, where this commanded position can be anywhere within the range of movement. Early servos, and a precursor device called an escapement, could only move to a limited number of set positions.

To reduce the mechanical complexity, newer model helicopters use a software system (usually running on the transmitter) to mix the control inputs of three interdependent servos to control the swashplate. The three servo linkages are arranged around the swashplate at 120° intervals (there is a variation that uses 140° + 140° + 80° intervals). In addition to lower mechanical complexity, the interdependent servos share the workload.

This lowered or raised the pressure on one side of a servo piston, the other side being attached to the original supply without passing through the valve. Any precession of the gyros, due to movement of the aircraft, caused the pistons to move due to the differential pressure. This motion was smoothed by an oil-filled dashpot, one for each of the three servos. The entire ABS sat within the stabilized frame that was powered by the servos.

Positioning servomechanisms were first used in military fire-control and marine navigation equipment. Today servomechanisms are used in automatic machine tools, satellite-tracking antennas, remote control airplanes, automatic navigation systems on boats and planes, and antiaircraft-gun control systems. Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens.

Manufacturers and distributors of hobby RC servos often use a specific shorthand notation of mechanical properties of the servos. Two figures are typically stated: angular speed of servo shaft rotation and mechanical torque produced on the shaft. Speed is expressed as a time interval that a servo requires in order to rotate the shaft for 60° angle. Torque is expressed as weight that can be pulled up by the servo if it hangs from a pulley with a certain radius mounted on the shaft.

Facial expressions can provide rapid feedback on the progress of a dialog between two humans, and soon may be able to do the same for humans and robots. Robotic faces have been constructed by Hanson Robotics using their elastic polymer called Frubber, allowing a large number of facial expressions due to the elasticity of the rubber facial coating and embedded subsurface motors (servos). The coating and servos are built on a metal skull. A robot should know how to approach a human, judging by their facial expression and body language.

Radio control servos are connected through a standard three-wire connection: two wires for a DC power supply and one for control, carrying a pulse-width modulation (PWM) signal. Each servo has a separate connection and PWM signal from the radio control receiver. This signal is easily generated by simple electronics, or by microcontrollers such as the Arduino. This, together with their low-cost, has led to their wide adoption for robotics and physical computing. RC servos use a three-pin 0.1" spacing jack (female) which mates to standard 0.025" square pins.
|
|
Each PWM defines a value that is used by the servo to determine its expected position. The first type is "absolute" and defines the value by the width of the active-high time pulse with an arbitrarily long period of low time. The second type is "relative" and defines the value by the percentage of time the control is active-high versus low-time. The "absolute" type allows up to eight servos to share one communication channel by multiplexing control signals using relatively simple electronics and is the basis of modern RC servos.
|
|
An intermediate mechanical mixing system is used to transfer the control inputs from the servos to the swashplate, therefore the name of mechanical CCPM (mCCPM). This requires an elaborate system of control rods and levers, which often contains many ball bearings.

"Servo Switch". "Remote Control Circuit Through RF Without Microcontroller" "Radio control transmitter encoder circuit, uses bog standard components" Often a Signetics NE544 IC or a functionally equivalent chip is used inside the housing of low-cost RC servos as the motor controller—it decodes that servo control pulse train to a position, and drives the motor to that position.

|
Any difference between the actual and wanted values (an "error signal") is amplified (and converted) and used to drive the system in the direction necessary to reduce or eliminate the error. This procedure is one widely used application of control theory. Typical servos can give a rotary (angular) or linear output.

Later, bombs could be detonated by radio control. Initially, simple servos from radio-controlled aircraft were used to close the electrical circuit and supply power to the detonator. After the British developed jammers, IRA technicians introduced devices that required a sequence of pulsed radio codes to arm and detonate them. These were harder to jam.

The phases of the elevation and azimuth signals are then compared with the sum signal to determine error polarity. These errors are detected, commutated, amplified, and used to control the antenna- positioning servos. A part of the reference signal is detected and used as a video range tracking signal and as the video scope display.

It utilized pneumatic hydraulic servos, which had a tendency to react slowly to inputs, and this often led to overcompensation of the aircraft's corrected course. This caused navigation and control issues when pilots were flying in poor weather or rough air. To fix these problems, the Sperry A-5 autopilot was developed. This was the first all electric autopilot.

The Royal Navy began experimenting with Remote Power Control (RPC) on HMS Champion in 1928 and began using RPC to control searchlights in the early 1930s. During WW2 RPC was used to control gun mounts and gun directors. Modern servomechanisms use solid state power amplifiers, usually built from MOSFET or thyristor devices. Small servos may use power transistors.

As the helicopter was manufactured in the United States, the U.S. National Transportation Safety Board (NTSB) has taken part in the investigation. In November 2005, the NTSB issued an "urgent" recommendation to the FAA to require all S-76 operators to carry out "immediate visual and laboratory examinations" of main rotor servos for plasma flakes and other contamination. The helicopter manufacturer, Sikorsky Aircraft, rejected these findings, saying it and servo manufacturer HR Textron "do not agree that the servo caused the mishap". In December 2005 the company, however, issued an all-operators letter recommending that operators carry out internal leakage tests of all S-76 main rotor servos, at the same time emphasizing that testing with an intentionally degraded servo "has not identified any safety of flight issues".

The Great Eastern was one of the largest steamships of its time and employed a steam powered rudder with feedback mechanism designed in 1866 by John McFarlane Gray. Joseph Farcot coined the word servo in 1873 to describe steam-powered steering systems. Hydraulic servos were later used to position guns. Elmer Ambrose Sperry of the Sperry Corporation designed the first autopilot in 1912.

Disc brakes exhibit no self-applying effect because the hydraulic pressure acting on the pads is perpendicular to the direction of rotation of the disc. Disc brake systems usually have servo assistance ("Brake Booster") to lessen the driver's pedal effort, but some disc braked cars (notably race cars) and smaller brakes for motorcycles, etc., do not need to use servos.

A less stable aircraft requires smaller control deflections to initiate maneuvering; consequently drag and control surface imposed stresses will be reduced and aircraft responsiveness will be enhanced. Since these characteristics will typically make control by the pilot difficult or impossible, an artificial stability will typically be imposed using computers, servos, and sensors as parts of a fly by wire control system.

Radio- control jets require an onboard FADEC (full authority digital engine control) controller; this controls the turbine, as on a full-size aircraft. RC jets also require electrical power. Most have a lithium polymer (LiPo) battery pack at 8–12 volts that controls the FADEC. There is also a LiPo for the onboard servos that control ailerons, elevator, rudder, flaps and landing gear.

This allowed the autopilot to detect the velocity and acceleration of the change. The calculated change was then communicated quickly to the control surfaces by independent electro-hydraulic servos. This led to faster, more stable corrections of the aircraft. The faster stabilization of the aircraft by the A-5 autopilot made it possible for new bombsights to be used on military aircraft.

On elevator input, the servos work opposite, one surface moves to the "left" and the other to the "right" which gives the effect of both moving up and down, causing pitch changes in the aircraft. V-Tails are very popular in Europe, especially for gliders. In the US, the T-Tail is more common. V-Tails have the advantage of being lighter and creating less drag.

Older model helicopters use three independent servos to manipulate the swashplate. The elevator servo is used to tilt the swashplate forward and aft (longitudinal cyclic), varying the aircraft's pitch. The aileron servo is used to tilt the swashplate left and right (lateral cyclic), varying the aircraft's roll. The collective pitch servo raises and lowers the entire swashplate, varying the collective, and hence the pitch of all the rotor blades collectively.

The AN/MSQ-77 radar track began after the aircraft (A/C) arrived near the Initial Point (IP) on a heading toward the target. When the computer's groundspeed and elevation rate servos had stabilized to the A/C cartesian velocity from the differentiating amplifiers, an operator placed the central into "computer track" to provide rate-aided tracking signals to the radar. With the computer track and the central having target position, A/C heading, & bomb type information; and with the Bomb Trajectory Group's servos tracking the bomb-in-aircraft course and pitch, the operator then activated the BTG integrators for the computer simulation to begin integrating a bomb trajectory from the A/C coordinates at that integration start point. Acceleration voltages from the BTG dynamic models were double-integrated by the 6 computer amplifiers which generated 3 voltages for the simulated bomb displacement (altitude, north, & east deltas) which were summed to the A/C position (simulated bomb release point, BRP).

This mechanism also needed to be able to drive motors for fans, pumps and robotic servos, and needed to be compact enough to interface with lamp dimmers. PWM emerged as a solution for this complex problem. One early application of PWM was in the Sinclair X10, a 10 W audio amplifier available in kit form in the 1960s. At around the same time PWM started to be used in AC motor control.

Wendl attended Washington University in St. Louis, graduating with BS in Electrical Engineering (EE) from the School of Engineering and Applied Science in 1958. He did his graduate work at the same institution under John Zaborszky, working as an instructor for physics and EE courses and completing a thesis on the control of servos for heated gases in 1961.Gregory, J. (1980) Who's Who in Engineering, 4th ed., American Association of Engineering Societies.

Such machines translated the tracer movements to input for servos that worked the machine leadscrews or hydraulics. They also spurred the development of antibacklash leadscrew nuts. All of the above concepts were new in the 1920s but became routine in the NC/CNC era. By the 1930s, incredibly large and advanced milling machines existed, such as the Cincinnati Hydro-Tel, that presaged today's CNC mills in every respect except for CNC control itself.

Due to the variety of constructions now available, the technology is used in applications from high temperature military to low cost pump and basic servos. Another approach (Magnax) is to use a single stator sandwiched between two rotors. One such design has produced peak power of 15 kW/kg, sustained power around 7.5 kW/kg. This yokeless axial flux motor offers a shorter flux path, keeping the magnets further from the axis.

An air bottle, pressurized to , supplied air for the servos and also supplied the air that spun the three, air-blown gyroscopes in the missile's inertial navigation system. A high pressure air supply from the aircraft was also required to spin the gyros before the missile was launched.Flight (1957), p. 227 The purpose of the control system was to keep the missile centred in the guidance beam emitted by the launch aircraft.

Strassman performed in New York's comedy clubs, including the Improv. In 1980, Strassman (along with his main ventriloquist character Chuck Wood) appeared in Roger Corman's horror movie Humanoids from the Deep. In 1986, Strassman added remote control to his puppet, Chuck Wood, using transmitters, motors, and servos, from his hobby flying remote control model airplanes. He discovered a remote clutch system in a NASA facility that could be integrated into his own dummies.

The origin of the word is believed to come from the French "Le Servomoteur" or the slavemotor, first used by J. J. L. Farcot in 1868 to describe hydraulic and steam engines for use in ship steering.IEEE Industry Applications Magazine March/April 1996, pg 74 The simplest kind of servos use bang–bang control. More complex control systems use proportional control, PID control, and state space control, which are studied in modern control theory.

A coolant heat-exchanger was installed which upon startup, warmed the gearbox oil quicker. A rod-driven actuation system, which replaces the 348's cable operated system, was also added for precise gear shifts. The frame is a steel monocoque with tubular steel rear sub-frame with front and rear suspensions using independent, unequal-length wishbones, coil springs over gas-filled telescopic shock absorbers with electronic control servos and anti-roll bars.

Bentley Mulsanne (rear 3/4 view) Interior The first Mulsanne produced, with chassis number 00001, was sold in 2009 at the Gooding & Company Pebble Beach auction for US$500,000 (US$550,000 after buyer premium) to an undisclosed bidder. Deliveries in England began in Summer 2010. Features include stainless steel knobs on the dashboard which control the vent plungers which are electronic micro switches that control electric servos. The feedback remains that of a metal rod to control the damper.

Easy manual cranking of the time line brought the dynamic test to its desired end point, when dials were read. As was typical of such computers, flipping a lever on the handcrank's support casting enabled automatic reception of data and disengaged the handcrank gear. Flipped the other way, the gear engaged, and power was cut to the receiver's servo motor. The mechanisms (including servos) in this computer are described superbly, with many excellent illustrations, in the Navy publication OP 1140.

Oral History of Grant Saviers, Computer History Museum, 17 May 2011 DEC pioneered a number of HDD technologies, including sampled data servos (RL01, 1977) and serial HDD interfaces (Standard Disk Interconnect, 1983). The last internally developed disk drive family (RA9x series) used plated media, departing from the HDD industry trend to carbon overcoated sputtered media. DEC designated a $400 million investment to bring this product line into production. The RA92 (1.5 GB) was introduced in 1992, using a 14-inch platter.

Sailboats use the power of the wind acting on sails to propel the boat. Model sailboats are typically controlled via a multi-channel radio transmitter in the hands of the operator with a corresponding receiver in the boat. By changing the position of the two joysticks on the transmitter signals are sent over two separate channels on a single radio frequency (assigned to the individual boat/operator). On the boat, the radio receiver is connected to two battery- powered electric motors or servos.

The Robot communicated with a proprietary 8-bit protocol, yet had no microprocessors/pal's/pics/ram, O/S or other modern logic device. In 1987, Clay Paky began producing their first scanners, the Golden Scan 1 & Crystal Scan. They utilized stepper motors instead of servos and used a HMI 575 lamp, bright and with a far more uniform beam brightness. This was followed by the Intellabeam in 1989, released by High End, who at the time were the distributors for Clay Paky.

Cluny also received estates (villas) and male and female slaves (servos et ancillas). The donation was confirmed by Urraca, Alfonso VII, the queen's daughter Sancha Raimúdez, Diego Gelmírez, Pelayo of Oviedo, Diego of León, Peter III of Lugo, the prior of the monastery of San Zoilo de Carrión, and a "curious mixture of [lay] Galicians and Asturians".Reilly (1982), 164. The charter was drawn up by a canon of the Cathedral of León who had probably followed the royal court to Lugo.

This type of servomotor is not widely used in industrial motion control, but it forms the basis of the simple and cheap servos used for radio- controlled models. More sophisticated servomotors use optical rotary encoders to measure the speed of the output shaft and a variable-speed drive to control the motor speed. Both of these enhancements, usually in combination with a PID control algorithm, allow the servomotor to be brought to its commanded position more quickly and more precisely, with less overshooting.

In the concluding passage of the chronicle, Henry expresses his joy over the fact that Virgin Mary has helped the missionaries from Riga to banish Tharapita and drown the Pharaoh (i.e., the Devil). Gloria Dei et domini nostri Iesu Christi et beate Marie Virginis servis suis Rigensibus in Osilia talia humiliter, obsides et tributa recipere, captivos omnes christiani nominis restituere, cum victoria redire! Quod reges hactenus non potuerunt, hec beata virgo per servos suos Rigenses breviter et leniter ad honorem sui nominis adimplevit.

However, in many modern automatic transmissions, the valves are controlled by electro-mechanical servos which are controlled by the electronic [engine control unit] (ECU) or a separate transmission control unit (TCU, also known as transmission control module (TCM). Modern designs have replaced the mechanical governor with an electronic speed sensor and computer software. The engine load is monitored either by a throttle cable or a vacuum modulator. Modern designs have replaced these mechanical devices with an electronic signal transmitted via a CAN bus.

Joystick-controlled electric servos operated the rudder (aft) and hydroplanes (front). Nautilus was much smaller than the Danish Kobben-class submarine at about two fifths the length, two fifths the width, and running at just above one third the speed. In early 2009, an automatic snorkel system was installed so that the submarine could sail submerged on diesel power, and in August it sailed out from Køge submerged. The submarine could be operated by a single person from the control room.

Held in a violet tower and guarded by Servos, one of the member of the royal family of Ahnmik, the shm'Ecl are a painful reminder of the dangers of falcon magic. Ecl is the Void, it is the absence of even nothingness that surrounds Mehay (existence). This is where falcons flee when their magic overwhelms them or they enter Ecl as an escape from the pain of the mortal world. Darien appears to be one of the shm'Ecl and nothing more.

BOE–Bot is short for Board of Education robot. It is the trade name of a robot kit that is used in junior high, high school and college robotics classes. It consists of a main circuit board (the Board of Education) and breadboard, a plug–in BASIC Stamp microcontroller, two servo motors to drive the wheels, and an aluminum chassis that the parts bolt onto. Students can use Erector set parts, Lego blocks, and additional servos to build custom projects.

The earliest tubes, like the Deforest Spherical Audion from c. 1911, used the typical light bulb Edison socket for the heater, and flying leads for the other elements. Other tubes directly used flying leads for all of their contacts, like the Cunningham AudioTron from 1915, or the Deforest Oscillion. Type C6A xenon thyratrons, used in servos for the U.S. Navy Stable Element Mark 6, had a mogul screw base and L-shaped stiff wires at the top for grid and anode connections.

Unique to JR Propo's radios is the company's patented ABC&W; technology, or Automatic Blocking Circuit with Window. Simply put, this system rapidly reroutes incoming signals through a series of ever-smaller electronic "windows," effectively blocking out spurious signals which cause radio "glitching". Any signal that does get through the system is filtered before being sent to the servos all without noticeable lag or delay. If the signal is unable to be processed, it is rejected, again without noticeable reaction.

The rocket engine nozzles were slightly offset to rotate the missile - this increased accuracy by evening out the effect of any slight asymmetry in thrust. This configuration drastically limited both range and flight duration, but was used because of fears that ionised particles in the hot, rocket motor exhaust stream would interfere with the guidance radar signals; further development showed the fears were unfounded. Steering was accomplished by four rudders in a cruciform configuration. These were moved by four pairs of pneumatic servos, operated by solenoid valves.

Your Majesty was met with generally positive reviews from music critics. At Metacritic, the album received an average score of 73, based on 9 reviews. Chart Attack writer Steve Servos said: "[g]one are the emo labels and in their place the band show off an appreciation for the classic pop-influences-rock sound". He was not surprised to hear "the full band version" of Elliott Smith because the Anniversary were working with Schnapf, "with a little Rufus Wainwright thrown in for good measure".

Colin Chapman developed the original concept of computer management of hydraulic suspension in the 1980s to improve cornering in racing cars. Lotus fitted and developed a prototype system to a 1985 Excel with electro-hydraulic active suspension, but never offered it for sale to the public, although many demonstration cars were built for other manufacturers. Sensors continually monitor body movement and vehicle ride level, constantly supplying the computer with new data. As the computer receives and processes data, it operates the hydraulic servos, mounted beside each wheel.

At each hydraulic cylinder, a pressure sensor monitors the hydraulic pressure. As the ABC controller receives and processes data, it operates four hydraulic servos, each mounted in series on a spring strut, beside each wheel. Almost instantaneously, the servo regulated suspension generates counter forces to body lean, dive and squat during various driving maneuvers. A suspension strut, consisting of a steel coil spring and a shock absorber are connected in parallel, as well as a hydraulically controlled adjusting cylinder, are located between the vehicle body and wheel.

In the AAS method, the set of servo systems (focus, tracking, sled, and spindle servos) keeps the laser beam focused on the spiral track, and allows disc rotation and laser head motion during the scanning. The amplification/detection board (DAB) is integrated into the CD/DVD drive unit and incorporates a photosensor and electronic circuitry to amplify the RF signal extracted from the photodiode transducer. The photosensor generates a trigger signal when detecting the trigger mark. Both signals are brought to the USB2.0 data acquisition board(DAQ) for digitization and quantification.

Servos in the computer boosted torque accurately to minimize loading on the outputs of computing mechanisms, thereby reducing errors, and also positioned the large synchros that transmitted gun orders (bearing and elevation, sight lead angles, and time fuze setting).These were electromechanical "bang-bang", yet had excellent performance. The anti-aircraft fire control problem was more complicated because it had the additional requirement of tracking the target in elevation and making target predictions in three dimensions. The outputs of the Mk 1A were the same (gun bearing and elevation), except fuze time was added.

His gifts to the world included bondage and mastery, and his high priestess was Cjarsa, who was aided by Araceli. The other gods on his side of the pantheon were the death goddess Brysh (whose priestess was Syfka) and the void goddess Ecl (whose priest was Servos). Anhamirak is the goddess of fire, love, life, beauty, passion, chaos, and destruction but above all, freedom. The only other named deity on the light side of the pantheon is Anhamirak's son Namid, god of life and patron of the priest Brassal.

This venture was short-lived, however, as Yes! Entertainment's corporate management and financial troubles ultimately resulted in AlchemyII withdrawing the licensing for Teddy. During this production of Teddy Ruxpin, an "interactive video" model was released under the branding "TV Teddy". The TV Teddy system consisted of a series of specially encoded VHS cassettes, an RF-transmitter that relayed signals encoded on the video track to the animatronic, and an animatronic RF-receiver consisting of a loudspeaker, and two servos which provided much-simplified eye and mouth movements compared to both the WOW and Playskool versions.

Footys are suitable for construction by virtually anyone. Because of their small size they place a high premium on sailing ability as opposed to Star Wars technology and no-one should feel themselves ruled out by lack of funds! For example, the well-known BUG design by Roger Stollery can be built largely from scrap materials for about £5 + radio gear (2 channel transmitter, receiver and 2 servos can be bought for around £40 and can be used in other models). Footys are very often designed and built by their owners.

The mechanism can also be deliberately modified to reduce the turbine efficiency in a pre- defined position. This mode can be selected to sustain a raised exhaust temperature to promote "light-off" and "regeneration" of a diesel particulate filter (this involves heating the carbon particles stuck in the filter until they oxidize away in a semi-self-sustaining reaction - rather like the self- cleaning process some ovens offer). Actuation of a VGT for EGR flow control, or to implement braking or regeneration modes in general, requires hydraulic actuators or electric servos.

Peter White of Drowned in Sound wrote that the album contained He added that the album featured "Nihilistic, angry pop gems covered in monster riffs" that "screams to rival anything on an Obituary record". Chart Attack reviewer Steve Servos noted that Lazzara's "somewhat raspy voice" was able to switch "with ease from melodic vocals to all-out screams". Kludge writer Ben Rayner said the band took the "emo-punk blueprint and use it to the best of their abilities." CMJ New Music Monthly writer Andrew Bonazelli noted musical similarities to fellow Victory band Thursday.

A V-Tail is a way of combining the control surfaces of the standard "+" configuration of rudder and elevator into a V shape. These ruddervators are controlled with two channels and mechanical or electronic mixing. An important part of the V-Tail configuration is the exact angle of the two surfaces relative to each other and the wing, otherwise the ratio of elevator and rudder outputs will be incorrect. The mixing works as follows: When receiving rudder input, the two servos work together, moving both control surfaces to the left or right, inducing yaw.

Fins were included, for "arrow stability", structurally anchored by an antenna ring. The stabilized platform used a pitch gyro and a yaw gyro, connected to pneumatic servos, which stabilized the platform along the pitch and yaw axes. Electrical carriages on the platform acted as integrating accelerometers. These signals were mixed with those from the SG-33 system, to drive the molybdenum-tungsten jet vane control servomotors. The SG-33 was fixed to the rocket, not the stabilized platform, and used three rate gyros for sensing roll, pitch and yaw deviations.

Semi-automatics facilitate easier gear shifts by removing the need to depress a clutch pedal or lever at the same time as changing gears. Depending on the mechanical build and design, they can use hydraulic, pneumatic, or electronic servos, electrical sensors, processors, and actuators to execute gear shifts when requested by the driver. Most cars which have a semi-automatic transmission are not fitted with a clutch pedal, since the clutch is remotely controlled, solely by electronic equipment. Similarly, most motorcycles with a semi-automatic transmission are not fitted with a hand-clutch lever.

A weak manifold vacuum under closed-throttle conditions shows that the butterfly valve or internal components of the engine (valves or piston rings) are worn, preventing good pumping action by the engine and reducing overall efficiency. Vacuum is often used to drive auxiliary systems on the vehicle. Vacuum-assist brake servos, for example, use atmospheric pressure pressing against the engine manifold vacuum to increase pressure on the brakes. Since braking is nearly always accompanied by the closing of the throttle and associated high manifold vacuum, this system is simple and almost foolproof.

Most of these first units were sold to the Army, in the original format of tins and the doorknob. Further revision resulted in the 1955 release of the "Bird Universal Medical Respirator" (sold as the Bird Mark 7 Respirator and informally called the "Bird"), a small green box that became familiar to hospital patients soon after its introduction. The Bird Mark 8 added the capabilities of NEEP (Negative End Expiratory Pressure). This was frequently used to power a set of fluidic servos (sort of relays.) He subsequently made a ventilator for infants, nicknamed the "Babybird".

Vicarm got orders for copies of the Stanford arm and MIT arm from various research organizations, including universities, General Motors, the National Bureau of Standards, AT&T; and the Naval Research Laboratory. The company soon offered a controller for the robots, using a Digital Equipment Corporation LSI-11, with 6502 microprocessors controlling the servos for each joint, including the end effector. They also developed a language, VAL, for controlling the robot.Victor Scheinman, an oral history, conducted in 2010 by Peter Asaro and Selma Šabanović, Indiana University, Bloomington Indiana, for Indiana University and the IEEE.

If the camera is fitted within a frame, this 'rig' can be designed to rotate horizontally and vertically and to change the picture format from portrait to landscape by rotating the camera. Adjustments to these angles can be made by manually setting the rig on the ground or by adjusting the rig while it is airborne using a remote control or an automatic controller in the rig. Commonly a radio control system, as used for model aircraft is used. The servos in these systems are readily adaptable to adjust rig positioning.

The talks between Copterline and Sikorsky Aircraft about how to divide damages arising from the crash broke down in December 2006, and Copterline sued Sikorsky Aircraft in a U.S. court in New York for damages of 60 million US dollars. In August 2007 it was announced that the cause of the crash was a failure of the hydraulic flight control system, caused by coating flaking off from servo pistons. The loosened plasma coating flakes blocked the return valves of the servos, causing the aircraft to abruptly lose its maneuverability.Helsingin Sanomat 8.8.

The technology replaces traditional components such as the pumps, hoses, fluids, belts and vacuum servos and master cylinders with electronic sensors and actuators. Drive-by- wire technology in automotive industry replaces the traditional mechanical and hydraulic control systems with electronic control systems using electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators. Some x-by-wire technologies have been already installed on commercial vehicles such as steer-by-wire, and throttle-by-wire. Brake-by-wire technology has been widely commercialized with the introduction of Battery Electric Vehicles and Hybrid Vehicles.

Laumer included a history of the Bolo as an appendix to one of his books. The Mark I is described as conventional large (150 tonne) tank equipped with various servos and mechanical devices to reduce crew requirements. It is developed around the year 2000 by the fictional Bolo Division of General Motors. By the 300-tonne Mark III it has AI allowing limited independent action and is powered by "ionic" batteries able to support combat-level activity for up to ten years and enabling operation even when fully submerged.

The MMT heralded a change in telescope design; all major optical telescopes since the MMT have been built with altitude-azimuth mounts. Several technologies pioneered at the MMT contributed to the success of the subsequent generation of large telescopes. These included: high dynamic-range servos for the altitude-azimuth mount; highly accurate pointing that eliminated the need for sky charts; co-alignment and co-phasing of multiple telescopes; improvements to optical performance by attention to the thermal environment of the facility; contributions to vacuum coatings deposition, optics cleaning, and maintenance; and early experiments in co-phased adaptive optics.

Servos, digital logic and solid-state electronics allowed engineers to build better and faster systems and over time these systems were improved and revised to the point where a single robot is capable of running 24 hours a day with little or no maintenance. In 1997, there were 700,000 industrial robots in use, the number has risen to 1.8M in 2017 In recent years, artificial intelligence (AI) with robotics is also used in creating an automatic labelling solution, using robotic arms as the automatic label applicator, and AI for learning and detecting the products to be labelled.

The rate of spin was varied by a programmer so that it did not couple with the changing resonance frequency of the first stage during flight. The upper-stage tub was visibly spun-up before launch. During first- stage flight, the vehicle was guided by a gyro-controlled autopilot controlling both air-vanes and jet vanes on the first stage by means of servos. Following a vertical launch from a simple steel table, the vehicle was programmed so that it was traveling at an angle of 40 degrees from the horizontal at burnout of the first stage, which occurred 157 seconds after launch.

Drive by wire, DbW, by-wire, Steer-by-wire, Fly-by-wire or x-by-wire technology in the automotive industry is the use of electrical or electro- mechanical systems for performing vehicle functions traditionally achieved by mechanical linkages. This technology replaces the traditional mechanical control systems with electronic control systems using electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators. Components such as the steering column, intermediate shafts, pumps, hoses, belts, coolers and vacuum servos and master cylinders are eliminated from the vehicle. This is similar to the fly-by-wire systems used widely in the aviation industry.

Between 2001 and 2003, new versions of Turna/S was developed with designations Turna-101A, -111B and -201C, featuring roll-damping avionics, aerodynamic packages, improved stability and greater reliability. Based on experience gained by launches from frigates and sorties in bad weather conditions, a new generation was evaluated under the name Tuna/G. Intermediate versions such as Turna-303C, -401C, -411C-501D and-502D served for improvements to autonomy, reliability, aerodynamics, lateral and directional stability as well as available volume for modular payloads. In order to offer alternative configurations, different components such as servos, propeller and engine were also integrated and tested.

Any appropriate gearbox can be used but normally a suitable manual gearbox from a Jaguar is used. The W152 uses the independent rear suspension (IRS) unit and front wishbones from the Jaguar donor car but instead of using the standard springs and shock absorbers, it utilises modern coil over shocks. The steering rack is sourced from an MGB and uses extenders to the track-rod ends to suit the wider track of the car. The car uses the standard Jaguar brake calipers and discs but uses a different, split system pedal box, remote fluid reservoirs and twin servos.

The key development in this area was the introduction of the servomechanism, which produced powerful, controlled movement, with highly accurate measurement information. Attaching two servos together produced a synchro, where a remote servo's motions were accurately matched by another. Using a variety of mechanical or electrical systems, the output of the synchros could be read to ensure proper movement had occurred (in other words, forming a closed-loop control system). The first serious suggestion that synchros could be used for machining control was made by Ernst F. W. Alexanderson, a Swedish immigrant to the U.S. working at General Electric (GE).

This device can be readily seen in modern off-road vehicles to engage 4WD and differential locks, and in older vehicles fitted with vacuum controlled servo motor cruise control. A brake booster is used on virtually all vehicles which use hydraulic brakes for their primary braking circuit. Vacuum servos are not used on vehicles which use cables, rods (or other mechanical linkages), or pressurized air systems for their primary brake circuits. A vacuum servo also known as a power booster or power brake unit uses a vacuum to multiply the drivers pedal effort and apply that effort to the master cylinder.

Aircraft gyrocompass built by SperryIn 1913, working with his son Lawrence Burst Sperry, Sperry created a gyro that could control the elevators and ailerons of an aircraft through a series of servos. Sperry successfully implemented his gyrostablizer technology, formerly thought to be only applicable to large ships, because of their high weight, into aircraft. In June 1914, Sperry and his son won the Aero Club of France's competition to build a safer aircraft, demonstrating the stabilizer with his son doing a "no-hands" flight past the judges. He also was awarded a Franklin Institute Medal in the same year.

Another common feature is the addition of pan and tilt capability to the camera, provided by servos. This, when coupled with video goggles and "head tracking" devices creates a truly immersive, first-person experience, as if the pilot was actually sitting in the cockpit of the RC aircraft. Receiving equipment—commonly referred to as the "Ground Station"—generally consists of an analog video receiver (matching the frequency of the transmitter on board the aircraft) and a viewing device. More complex Ground Stations often include a means to record the received image along with more sophisticated antennas for achieving greater range and clarity.

Mazda 323F Hidden headlamps were introduced in 1936, on the Cord 810/812. They were mounted in the front fenders, which were smooth until the lights were cranked out—each with its own small dash-mounted crank—by the operator. They aided aerodynamics when the headlamps were not in use, and were among the Cord's signature design features. Later hidden headlamps require one or more vacuum-operated servos and reservoirs, with associated plumbing and linkage, or electric motors, geartrains and linkages to raise the lamps to an exact position to assure correct aiming despite ice, snow and age.

In the ABC system, a computer detects body movement from sensors located throughout the vehicle, and controls the action of the active suspension with the use of hydraulic servomechanisms. The hydraulic pressure to the servos is supplied by a high pressure radial piston hydraulic pump. A total of 13 sensors continually monitor body movement and vehicle level and supply the ABC controller with new data every ten milliseconds. Four level sensors, one at each wheel measure the ride level of the vehicle, three accelerometers measure the vertical body acceleration, one acceleration sensor measures the longitudinal and one sensor the transverse body acceleration.

Similar to a flower, the robotic flower contains components such stems and leaves, with small sensors and effectors embedded in the structure. The flower robot developed at Carnegie Mellon University utilized a seven degree of freedom structure, with one used to move the stem towards the left and right, and six other for moving the leaves. Built using simple DC servos, the base structure of the robot actuates the leaves, and uses the IR sensors built in on three of its petals to track objects. Designed as an intelligent home appliance, the robotic flower has a variety of different functions.

The river begins at Mud Lake in geographic Servos Township in Unorganized North Sudbury District. It flows west through Graham Lake, turns south, and is crossed by the Canadian Pacific Railway main line. It enters Lovering Lake at the community of Paget, flows west under Ontario Highway 69 into Kakakiwaganda Lake, then turns sharply east back under Highway 69 to Round Lake. It heads south southeast, passes briefly through the northeast corner of geographic Cox Township, enters the municipality of French River, is crossed by Ontario Highway 64 and Ontario Highway 607, and reaches its mouth at the French River near the central community of French River.

If the bowl (called an "umbrella") is not centered above the exciter coil, either or both coils have an output that represents the offset. This voltage is phase- detected and amplified to drive two DC servo motors to position the umbrella in line with the coil. The umbrella support gimbals rotate in bearing with the gun director, and the servo motors generate level and crosslevel stabilizing signals. The Mk. 1A's director bearing receiver servo drives the pickoff gimbal frame in the stable element through a shaft between the two devices, and the Stable Element's level and crosslevel servos feed those signals back to the computer via two more shafts.

In 2010, Blake Bevin, a self- described "science geek", created a prototype of self-lacing shoes, inspired by Marty's Nike MAG; once the user steps in, a sensor records the pressure of the foot on the sole and activates two servo motors, which apply tension to the laces, thus tightening the shoe. A touch-activated switch reverses the servos and loosens the laces. Bevin posted DIY instructions on how to recreate the power laces technology on her website. Later, Bevin founded Power Laces, LLC started a Kickstarter project in order to fund the development of commercial version and successfully raised the pledged goal of $25,024.

The DJI RoboMaster EP is the second educational robot from the RoboMaster line, officially released on March 9, 2020, although it was first anonymously teased in a RoboMaster S1 commercial on YouTube dated on November 25, 2019. The EP shares similar chassis and Mecanum wheel designs with the S1, is compatible with multi-party hardware, supports multiple software platforms and has an open SDK. The new hardwares include high-performance servos, robotic arms, grippers, infrared depths sensors, sensor transfer, modules and power transfer modules, as well as more than 50 programmable modules. The steering gear of the RoboMaster EP can be customized through a programming interface.

While many models use a combination of switches and/or relays physically actuated by servos to control the propulsion system, most newer models now use either Electronic Speed Control units or solid-state switching boards, such as those found in Robot combat, greatly reducing the complexity of the wiring of the propulsion system. Propulsion is provided by electric motors coupled to shafts passing through stuffing tubes driving semi-scale propellers. All active mechanical systems are required to be operated via electrical or pneumatic means. Any and all mechanisms relying upon chemical combustion which could contaminate the water with fuels, oils, or other chemicals are banned.

Inspired by his childhood obsession with Astroboy and other fictional characters, Takahashi decided to study robotics after completing a sociology degree. Takahashi prefers to work on smaller robots, as they are easier to handle and people have more realistic expectations of them. Unlike machines, which are cold and uninviting, humans can relate to robots because they have bodies like humans or animals, which opens up new possibilities for communication, which Takahashi believes is their greatest strength. His goal is to create robots with exaggerated movements, and to do that he prefers small, tough servos with metal gears, using the best hardware he can afford.

An RC flyer demonstrating knife edge flying A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is controlled remotely by an operator on the ground using a hand-held radio transmitter. The transmitter communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on the position of joysticks on the transmitter. The control surfaces, in turn, affect the orientation of the plane. Flying RC aircraft as a hobby grew substantially from the 2000s with improvements in the cost, weight, performance and capabilities of motors, batteries and electronics.

Care must be taken when building models from wood kits since construction flaws may affect the model's flying characteristics or even result in structural failure. Smaller balsa kits will often come complete with the necessary parts for the primary purpose of non- flying modeling or rubber band flight. These kits will usually also come with conversion instructions to fly as glow (gas powered) or electric and can be flown free-flight or radio-controlled. Converting a kit requires additional and substitution parts to get it to fly properly such as the addition of servos, hinges, speed controls, control rods and better landing gear mechanisms and wheels.

In addition, most electronic speed controllers can use the electric motor as a magnetic brake, offering better control of the model than is possible with a mechanical speed control. Mechanical speed controllers use a network of resistors and switch between them by rotating a head with an electrode around a plate that has electrical contacts. Mechanical speed controllers are prone to being slow to react because they are actuated by servos, waste energy in the form of heat from the resistors, commonly become dirty and perform intermittently, and lack a dedicated braking ability. They appear only in vintage RC models, and are now essentially obsolete.

As a writer, Adonias Aguiar Filho searched for inspiration for his fiction in the "zona cacaueira" (Cocoa plantations) close to Ilhéus, back to his origins in the South of Bahia, where he was born and raised. This ambiance is well displayed in his first novel, Os servos da morte (The Servants of Death), published in 1946. In the form of the romance novel, reality served as an opportunity to recreate a world charged with symbolism, in the situations as well as in the characters, bearing witness to a tragic sense of life and worldview. He was part of the , a literary society devoted to spirituality and Catholic tradition.

The Citroën DS, introduced in 1955, used a hydraulic system to select gears and operate the conventional clutch using hydraulic servos. There was also a speed-controller and idle speed step-up device, all hydraulically operated. This allowed clutchless shifting with a single selector mounted behind the steering wheel. This system was nicknamed 'Citro-Matic' in the U.S. The 1967 VW WSK (Wandlerschaltkupplungsgetriebe; English: "hydrodynamic torque converter shift/clutch gearbox"), used in the Beetle and Karmann Ghia, was one of the first gearboxes of this kind, which had an automatic mechanical clutch and a hydrodynamic torque converter; shifting gears was done manually by the driver.

The development and dissemination throughout industry of NC, CNC, PLC, and other control technologies provided a new way to control the movement of the milling cutter: via feeding information from a program to actuators (servos, selsyns, leadscrews, machine slides, spindles, and so on) that would move the cutter as the information directed. Today most commercial machining is done via such programmable, computerized methods. Home machinists are likely to work via manual control, but computerized control has reached the home-shop level as well (it's just not yet as pervasive as its commercial counterparts). Thus pantograph milling machines are largely a thing of the past.

The number of pulses per frame gives the number of controllable channels available. The advantage of using PPM for this type of application is that the electronics required to decode the signal are extremely simple, which leads to small, light-weight receiver/decoder units. (Model aircraft require parts that are as lightweight as possible). Servos made for model radio control include some of the electronics required to convert the pulse to the motor position – the receiver is required to first extract the information from the received radio signal through its intermediate frequency section, then demultiplex the separate channels from the serial stream, and feed the control pulses to each servo.

Fort Smith Flightmasters: Radio Control Systems (Part 2) with illustrations of an early installation and descriptions of various escapements. In the late 1950s, RC hobbyists had mastered tricks to manage proportional control of the flight control surfaces, for example by rapidly switching on and off reed systems, a technique called "skillful blipping" or more humorously "nervous proportional". By the early 1960s transistors had replaced the tube and electric motors driving control surfaces were more common. The first low cost "proportional" systems did not use servos, but rather employed a bidirectional motor with a proportional pulse train that consisted of two tones, pulse width modulated (TTPW).

|
The pulse is repeated in a frame of between 10 and 30 milliseconds in length. Off-the-shelf servos respond directly to servo control pulse trains of this type using integrated decoder circuits, and in response they actuate a rotating arm or lever on the top of the servo. An electric motor and reduction gearbox is used to drive the output arm and a variable component such as a resistor "potentiometer" or tuning capacitor. The variable capacitor or resistor produces an error signal voltage proportional to the output position which is then compared with the position commanded by the input pulse and the motor is driven until a match is obtained.

Almost instantly, the servo-regulated suspension generates counter forces to body lean, dive, and squat during driving maneuvers. Williams Grand Prix Engineering prepared an active suspension for F1 cars in 1992, creating such successful cars that the Fédération Internationale de l'Automobile decided to ban the technology. Computer Active Technology Suspension (CATS) co-ordinates the best possible balance between ride quality and handling by analysing road conditions and making up to 3,000 adjustments every second to the suspension settings via electronically controlled dampers. The 1999 Mercedes-Benz CL-Class (C215) introduced Active Body Control, where high pressure hydraulic servos are controlled by electronic computing, and this feature is still available.

Physical computing involves interactive systems that can sense and respond to the world around them. While this definition is broad enough to encompass systems such as smart automotive traffic control systems or factory automation processes, it is not commonly used to describe them. In a broader sense, physical computing is a creative framework for understanding human beings' relationship to the digital world. In practical use, the term most often describes handmade art, design or DIY hobby projects that use sensors and microcontrollers to translate analog input to a software system, and/or control electro-mechanical devices such as motors, servos, lighting or other hardware.

Nissan Chief Creative Officer Shiro Nakamura said that the angular lines and high-tech vents of the GT-R (R35) were inspired by the Japanese anime series Gundam. Mitsubishi has cooperated with Bandai to create a simulator for concept cars, the test-type of this simulator will be decorated like the Gundam cockpit and become a simulation theatre in the Toyota theme park, Mega Web, located in Tokyo. In 2018, Japanese engineer Masaaki Nagumo from Sakakibara Kikai completed construction of a functional bipedal mecha inspired by the Gundam franchise. The device, standing 8.5 meters tall and weighing about 7 tonnes, possesses fully functional arm and leg servos.

The late 1911 reform of the Roman Breviary by Pope Pius X changed the psalmody radically, dividing several psalms into shorter portions. To Prime it assigned each day three psalms or portions of psalms, each day different.Table comparing the 1568 and the 1911 psalters To these elements, which make Prime similar to the other Little Hours, Prime adds some prayers that are called the office of the chapter: the reading of the martyrology, the prayer "Sancta Maria et omnes sancti" ("May holy Mary and all the Saints..."), a prayer concerning work, "Respice in servos tuos . . . Dirigere et sanctificare" ("Look upon thy servants... Direct and sanctify"), and a blessing.

Primarily, the flower robot is used as a background sensing device, as it contains sensors for temperature, pressure, voice and light intensity. Unlike other sensors with similar purpose, the appearance of the flower robot makes it easier blend into various rooms, providing more convenient control and accurate results. In addition, the flower robot is capable of small movements using its servos, which can be used to mimic the blooming flower and the stirring of leaves in the wind, creating an aesthetically pleasing environment. Other functions of the flower robot include vision or voice recording, illumination and the use of a scent emitter and a humidifier.

An exception to this standard were mechanical storytelling dolls from the 1980s (e.g. Teddy Ruxpin) which used the Type IV metal configuration cassette shell but had normal Type I voice grade tape inside. These toys used the Type IV notches to detect that a specially coded tape had been inserted, where the audio of the story is stored on the left channel and various cue tones to tell the doll's servos how and when to move along with the story on the right channel. Most pre-recorded chrome cassettes require 120 µs equalisation and are treated as Type I (with notches as Type I ferric cassettes), to ensure compatibility with budget equipment.

Raymond C. Goertz (March 12, 1915 - June 4, 1970) was an American mechanical engineer and an early pioneer in the field of robotics, specifically remote- controlled robots (see telepresence). In 1949, while working for the Atomic Energy Commission at Argonne National Laboratory, Goertz filed a patent for an early master-slave manipulator () in order to handle radioactive material. Goertz recognized the value of electrically coupling manipulators and laid the foundations of modern tele-robotics and bilateral force-reflecting positional servos. Goertz also performed early research on the degrees of freedom necessary for smooth motion by remote manipulation and developed one of the first head-mounted displays as a prototype for virtual reality.

The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities. Flight controls allow pilots to control the collective (or throttle, on fixed pitch helicopters), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform the same maneuvers as full-sized helicopters, such as hovering and backwards flight, and many other maneuvers that full-sized helicopters cannot, such as inverted flight (where collective pitch control provides negative blade pitch to hold heli up inverted, and pitch/yaw controls must be reversed by pilot). The various helicopter controls are effected by means of small servo motors, commonly known as servos.

Electronic speed controls and servos are commanded by the receiver through pulse width modulation; pulse duration sets either the amount of current that an electronic speed control allows to flow into the electric motor or sets the angle of the servo. On these models the servo is attached to at least the steering mechanism; rotation of the servo is mechanically changed into a force which steers the wheels on the model, generally through adjustable turnbuckle linkages. Servo savers are integrated into all steering linkages and some nitro throttle linkages. A servo saver is a flexible link between the servo and its linkage that protects the servo's internal gears from damage during impacts or stress.

Her costume contains micro-servos that enhance her strength above normal human levels. The gloves of her costume contain steel micro-filaments, which form retractable claws at the fingertips when she flexes her fingers (triggering a magnetic surge which condenses the filaments into polarized talons) which enable her to tear through most surfaces and easily scale walls. Using this equipment, the Black Cat has been able to beat enemies who have superhuman abilities. The Black Cat has a miniature grappling hook device hidden in the "fur" of each glove, designed by her father Walter Hardy, which enables her to swing from buildings in a manner similar to Spider-Man, though not quite as fast.

He later helps Prowl during the events of "Five Servos of Doom" in uncovering how Sentinel is "capturing" high level Decepticons with seemingly no help. He remained on Earth until the end of "Predacon Rising", saying his goodbyes as he joins the Elite Guard in taking their prisoners to Cybertron. During the trip back to Cybertron, Jazz is one of the first to suspect that Sentinel Prime is putting his own personal ambitions ahead of whats best for the Autobots, particularly when Sentinel suddenly demands that Jazz refer to him as "Sir" or "Commander". Jazz is much more receptive to Optimus Prime's command style such as when he and Jazz use secret code to prep a trap for the Decepticons.

The standard ammunition is that designed for FH-70 (L15 HE and associated propelling charges) although in training the less effective but cheaper M107 with Green and White propelling charges is used. It is fitted with an auxiliary power unit to eliminate the need to run the main engine to keep the batteries charged while stationary; electrical servos drive the automated elevation, traverse, magazine, shell transfer arm and loader as well as power for electronics and communications. The vehicle is fitted with an autonomous navigation and gun laying dynamic reference unit (DRU) mounted on the trunnion. All main turret functions are controlled by a Turret Control Computer (TCC) with control and display units for the No 1 (Detachment Commander), No 2 (loader) and No 3 (layer).

Synchro systems were first used in the control system of the Panama Canal in the early 1900s to transmit lock gate and valve stem positions, and water levels, to the control desks. View onto the connection description of a synchro transmitter Fire-control system designs developed during World War II used synchros extensively, to transmit angular information from guns and sights to an analog fire control computer, and to transmit the desired gun position back to the gun location. Early systems just moved indicator dials, but with the advent of the amplidyne, as well as motor-driven high-powered hydraulic servos, the fire control system could directly control the positions of heavy guns."Naval Ordnance and Gunnery, Volume 1", 1957, U.S. Navy Manual, Chapter 10.

The most noteworthy change was that the front headlamps were fully faired into the wings of the car rather than protruding outwards as on previous models. As in every Bristol saloon since the 404, a compartment accessed via a hinged panel between the front of the driver's door and the rear of the front wheel arch housed the battery, fuse panel, windscreen wiper motor and brake servos. A similar panel on the other side of the car housed the spare wheel and jack. There were also 15 inch wheels as against the 16 inch size found on previous Bristols, and the disc braking system dating back to the 406 was revised for the first time since then, with a greatly updated system of braking circuits being introduced.

Differential amplifiers are found in many circuits that utilize series negative feedback (op-amp follower, non-inverting amplifier, etc.), where one input is used for the input signal, the other for the feedback signal (usually implemented by operational amplifiers). For comparison, the old-fashioned inverting single- ended op-amps from the early 1940s could realize only parallel negative feedback by connecting additional resistor networks (an op-amp inverting amplifier is the most popular example). A common application is for the control of motors or servos, as well as for signal amplification applications. In discrete electronics, a common arrangement for implementing a differential amplifier is the long-tailed pair, which is also usually found as the differential element in most op-amp integrated circuits.

The remote release for the boot (trunk) lid, located on the inside of the door opening on the B-post just under the door lock striker, was moved from the right hand side of the car to the left hand side. The location of this item was always independent of whether the car was left hand drive or right hand drive. Early (Series 1) 1750 GTV's featured the same bumpers as the Giulia Sprint GT Veloce, with the front bumper modified to mount the indicator / sidelight units on the top of its corners, or under the bumper on US market cars. The Series 2 1750 GTV of 1970 introduced other mechanical changes, including a dual circuit braking system (split front and rear, with separate servos).

The Norélic had a two-blade articulated rotor with undamped flapping hinges; the blades had the same chord and aerofoil from hub to tip and were each built around a single solid spar with ribs and a thin metal skin, all clamped together. Blade pitch was automatically controlled by small servo or pilot airfoils mounted on rods at right-angles to the rotors. Though reminiscent of the servos on the Hiller 360, those on the Norélic were themselves flappable and were intended to control both cyclic pitch and the flapping amplitude of the main rotors. Thus the cockpit cyclic pitch control was absent, and instead roll was produced by sideways motion of the hub via its parallel support pillars, which separated the centres of lift and gravity.

ESCs are normally rated according to maximum current, for example, 25 amperes or 25 A. Generally the higher the rating, the larger and heavier the ESC tends to be which is a factor when calculating mass and balance in airplanes. Many modern ESCs support nickel metal hydride, lithium ion polymer and lithium iron phosphate batteries with a range of input and cut-off voltages. The type of battery and number of cells connected is an important consideration when choosing a battery eliminator circuit (BEC), whether built into the controller or as a stand-alone unit. A higher number of cells connected will result in a reduced power rating and therefore a lower number of servos supported by an integrated BEC, if it uses a linear voltage regulator.

Such adapters will ensure that there is no electrical connection of any kind between both sides of the adapter, including ground. They use either transformers or opto-couplers to transfer a safe trigger impulse from the camera to the flash. They are powered by batteries, as their electronics cannot be powered from the flash. As an example, Minolta offered the PC terminal adapter PCT-100 (8825-691) for this purpose, which worked as a galvanic isolator and could withstand 400 volts DC or AC. The similar Sony flash sync terminal and ISO hotshoe adapters FA-ST1AM and FA-HS1AM also offer galvanic isolation as well, but only up to 60 volts DC or AC. Flash servos and radio triggers, e.g.

This system, and another commonly known as "Kicking Duck/Galloping Ghost", was driven with a pulse train that caused the rudder and elevator to "wag" though a small angle (not affecting flight owing to small excursions and high speed), with the average position determined by the proportions of the pulse train. A more sophisticated and unique proportional system was developed by Hershel Toomin of Electrosolids corporation called the Space Control. This benchmark system used two tones, pulse width and rate modulated to drive 4 fully proportional servos, and was manufactured and refined by Zel Ritchie, who ultimately gave the technology to the Dunhams of Orbit in 1964. The system was widely imitated, and others (Sampey, ACL, DeeBee) tried their hand at developing what was then known as analog proportional.

Although they did not accomplish any computation, electromechanical position servos were essential in mechanical analog computers of the "rotating-shaft" type for providing operating torque to the inputs of subsequent computing mechanisms, as well as driving output data-transmission devices such as large torque- transmitter synchros in naval computers. Other non-computational mechanisms included internal odometer-style counters with interpolating drum dials for indicating internal variables, and mechanical multi-turn limit stops. Considering that accurately controlled rotational speed in analog fire-control computers was a basic element of their accuracy, there was a motor with its average speed controlled by a balance wheel, hairspring, jeweled-bearing differential, a twin-lobe cam, and spring-loaded contacts (ship's AC power frequency was not necessarily accurate, nor dependable enough, when these computers were designed).

However, it was decided to opt for a traditional mechanical linkage approach that was augmented by a series of electrically-driven power assist units to effectively support actuation instead. The ailerons and rudder were split into multiple sections in order that, if a part of the servo-powered control system were to fail, a faulty section could be "trailed" so that it did not act against the remaining working sections. While the prototype aircraft had been fitted with advanced (but conventional) hydraulic controls, Saunders-Roe had intended production aircraft to use an analogue system based around electrical servos with hydraulic final control actuators. Such a system had been built and undergone ground-testing, but the Princess had been terminated prior to any aircraft having been fitted with the system.

Some complex scale models use a fly-by-wire approach to allow a multitude of extra working features. A radio-control transmitter's encoder unit can be adapted, with no RF signal board present, to send its control signals along insulated control lines, instead of broadcasting them using radio frequencies. If signals are sent down the lines, the normal serial multiplexing of the control signals by such an adapted RC transmitter's encoder unit, solely sending those signals along the usual duo or trio of control lines, gets picked up by decoding gear in the model - usually adapted from an RC receiver, without an RF "front end" section - and permits many functions to be controlled without the use of additional lines. Standard servos can then be used in the model.

In the space below and above the wing centre section were located the air, fuel, oxidant and warm-air pipes, telemetering transmitter, instruments and batteries as well as the autopilot, timing clock, wiring terminal fuses and the connections by which the test vehicle was carried on the parent aircraft. The rear section housed the combustion chamber, radar transponder, smoke-producing fluid, instruments and oscillators for combustion chamber pressure and tailplane angle, servos and dive mechanism for the tailplane which together with the fixed directional fin were fitted to the lower body prior. The single-piece wing was of mahogany with Dural inserts at the leading and trailing edges; it was of biconvex section and of tapered planform with an unswept half-chord line. The Dural inserts formed a convenient dipole-aerial system for the telemetering unit.

The control rod channels are cooled by an independent water circuit and kept at . The narrow space between the rod and its channel hinders water flow around the rods during their movement and acts as a fluid damper, which is the primary cause of their slow insertion time (nominally 18–21 seconds for the reactor control and protection system rods, or about 0.4 m/s). After the Chernobyl disaster, the control rod servos on other RBMK reactors were exchanged to allow faster rod movements, and even faster movement was achieved by cooling of the control rod tubes by a thin layer of water while letting the rods themselves move in gas. The division of the control rods between manual and emergency protection groups was arbitrary; the rods could be reassigned from one system to another during reactor operation without technical or organizational problems.

This was done by a radio altimeter signal which drove the autothrottle servos to a flight idle setting. As the accuracy and reliability of the ground based ILS localiser was increased on a step by step basis, it was permissible to leave the roll channel engaged longer and longer, until in fact the aircraft had ceased to be airborne, and a fully automatic landing had in fact been completed. The first such landing in a BEA Trident was achieved at RAE Bedford (by then home of BLEU) in March 1964. The first on a commercial flight with passengers aboard was achieved on flight BE 343 on 10 June 1965, with a Trident 1 G-ARPR, from Paris to Heathrow with Captains Eric Poole and Frank Ormonroyd. The Lockheed L-1011 TriStar had its autoland functionality placed in key roles during its marketing.

The Bomb Trajectory Group (BTG) was the AN/MSQ-77's analog ballistic computer using 3-dimensional double-integration to continually predict the bomb impact point from an aircraft track during a bomb run. The Cartesian aircraft data were propagated by the BTG mathematical modeling which included aerodynamics for different bombs, Earth "curvature and Coriolis corrections", and vacuum tube integrating amplifiers. The integration was based on the varying aircraft position and velocity prior to the bomb release, so as with the use of the Norden bombsight analog computer in World War II, a nearly steady bomb run was required for the AN/MSQ-77 to provide sufficient bombing accuracy. As in the 1950s Nike missile guidance system(s), electro-mechanical servos controlled sine/cosine resolvers in a feedback loop for computing the simulated bomb's horizontal velocity and along with the drop rate, the simulated bomb's airspeed and dive angle ("Pitch Servo").

John Whitney, Sr (1917-1995) was an American animator, composer and inventor, widely considered to be one of the fathers of computer animation.SIGGRAPH Whitney Profile page (retrieved 20 April 2012) In the 1940s and 1950s, he and his brother James created a series of experimental films made with a custom-built device based on old anti-aircraft analog computers (Kerrison Predictors) connected by servos to control the motion of lights and lit objects — the first example of motion control photography. One of Whitney's best known works from this early period was the animated title sequence from Alfred Hitchcock's 1958 film Vertigo,Alex Through the Looking-Glass: How Life Reflects Numbers and Numbers Reflect Life which he collaborated on with graphic designer Saul Bass. In 1960, Whitney established his company Motion Graphics Inc, which largely focused on producing titles for film and television, while continuing further experimental works.

At the same time, in the United States, analog computer pioneer Vannevar Bush took on a similar role to that of Lennard-Jones in the military effort after President Franklin Delano Roosevelt entrusted him with the bulk of wartime research into automatic control of fire power using machines and computing devices. According to Sarah Bergbreiter in her paper "Moving from Practice to Theory: Automatic Control after World War II," fire control for the downing of enemy aircraft by anti- aircraft guns was the priority. The analog electro-mechanical computing machines plotted the differential firing data while servos created by H.L. Hazen adapted the data to the guns for precise firing control and accuracy. Other improvements of a similar type by Bell Labs increased firing stability so that output from the differential engines could be fully used to compensate for stochastic behaviors of enemy aircraft and large guns.

Unlike earlier armors, this new armor does not appear to rely on motors and servos for motion. Instead, the nano-machines create a secondary artificial musculature over Stark's body, upon which additional rigid structures are assembled. This also enables the armor to self-repair and be almost invulnerable, as the armor is capable of transforming and healing itself as long as the power output from the arc reactor is not interrupted or terminated; when the armor is briefly apparently destroyed in a fight with an alternate version of the Scarlet Witch, it is restored to normal after only a matter of seconds (although it remains inactive long enough to require Spider- Man to rescue Stark from plummeting to the ground). In the 2012 "Ends of the Earth" storyline, Doctor Octopus is able to disable the armor using technology derived from the armor of Iron Man 2020.

When a tape was changed, the operator spent as much as half-an-hour, "lining-up" the VTR — that is, carrying out specialized technical adjustments to calibrate the machine to the tape before it was ready for playback. From VR-1200/2000 onward, improvements in head manufacturing/refurbishing tolerances, timebase correction, and greater thermal stability of solid-state electronics made tape changes possible in under a minute and servo calibrations needed only once per shift. From AVR-1 onward, servos were self calibrating and tape changes as fast as the operator could articulate threading. The few quadruplex VTRs which remain in service are used for the transfer and/or restoration of archival 2-inch quad videotape material to newer data storage formats, although mainstream TV serials from the 1950s to late 1960s have mostly already been remastered onto more modern media some years ago, even digitized within the last decade.

The idea of Limbitless Solutions came to life in 2014 after a team of engineering students at the University of Central Florida led an initiative to provide bionic 3D printed limbs to children. In their free time, the students took advantage of a donated Stratasys Dimension 3D printer in the engineering manufacturing lab on campus to create an affordable prosthetic that displayed their ideas of art and engineering all into one. Their method was the first of its kind and minimized the cost and time of traditional prosthetic manufacturing processes like CNC milling.Stratasys, 3d printed prosthetic arm Stratasys, 3d printed prosthetic arm CNN, UCF 3D printed arms for kids CNN, UCF 3D printed arms for kids The first 3D printed arm the students created was run with off-the-shelf servos and batteries which are activated by the electromyography muscle energy on the child’s limb.

In 1935 the DH.82 Queen Bee, a pilotless, radio-controlled variant of the Tiger Moth appeared, for use in training anti-aircraft gunners. Use of the word drone, as a generic term for pilotless aircraft, apparently originated from the name and role of the Queen Bee (i.e. the word drone is a reference to the male bee which makes one flight in search of the female queen bee and then subsequently dies)."The Flight of 'Drone' From Bees to Planes" Wall Street Journal, 26 July 2013"The Flight Of ‘Drone’ From Bees To Planes" Fortuna's corner The DH.82 had a wooden fuselage, based on that of the DH.60 Gipsy Moth (with appropriate structural changes related to cabane strut placement) and the wings of the Tiger Moth II. Queen Bees retained a normal front cockpit for test-flying or ferry flights, but had a radio-control system in the rear cockpit to operate the controls using pneumatically driven servos.

The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input. The ECC replaced the traditional mechanical stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle's cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC's touchscreen which would render climate control or stereo operation impossible. Multi-touch technology began in 1982, when the University of Toronto's Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass.

This design would be Conner's trademark look well into the 1990s. Logically, Conner's drives had some of the characteristics of the original MiniScribe drives (of which John Squires had also been a designer), with a large amount of intelligence built into the drive's central processing unit (CPU); Conner drives used a single Motorola 68HC11 microcontroller, and ran a proprietary real-time operating system that implemented the track-following algorithms (the "servo" system) in software, as well as managing the bus interface. Running these functions in software saved a lot of hardware; in 1986, most drives used a separate PID controller for the spindle, and used a CPU mainly to manage the bus interface and generate positioning pulses for a stepper motor. SCSI support added yet another CPU to interpret the SCSI commands, and track-following servos required analog components that often populated entire circuit boards of their own, thus driving up costs.

PDP-8I backplane, an example of automated wire wrapping Automated wire-wrap machines, as manufactured by the Gardner Denver Company in the 1960s and 1970s, were capable of automatically routing, cutting, stripping and wrapping wires onto an electronic "backplane" or "circuit board". The machines were driven by wiring instructions encoded onto punched cards, Mylar punched hole tape, and early micro computers. The earliest machines (14FB and 14FG models, for example) were initially configured as "horizontal", which meant that the wire wrap board was placed upside down (pins up) onto a horizontal tooling plate, which was then rolled into the machine and locked onto a rotating (TRP table rotational position of four positions) and shifting (PLP = pallet longitudinal position of 11 positions) pallet assembly. These machines included very large hydraulic units for powering the servos that drove the ball screw mounted "A" and "B" drive carriages, a tall electronics cabinet loaded with hundreds of IBM control relays, many dozens of solenoids for controlling the various pneumatic mechanical subsystems, and an IBM 029 card reader for positioning instructions.

This electrically-signalled control system, which also comprised the auto-stabiliser, not only transferred signals from cockpit controls such as the position of the stick, but also monitored feedback signals from the servos to provide stability of the systems itself. A total of three modes of control for the aerodynamic surfaces and/or the nozzle controls were permitted by the system: # Aerodynamic surfaces and air-jet nozzles controlled electrically via three independent servo-motors (with "three-way parallel" or "triplex" fail-safe operation) in conjunction with three autostabilizer control systems ("full fly-by-wire") # Hybrid-mode, in which the nozzles were controlled by servo/autostabilizer and the aerodynamic surfaces were linked directly to the manual controls # Direct mode, in which all controls were linked to the control stick XG900 Short SC.1 colour profile Modes 1 and 2 were selected on the ground; whenever the autostabilizer was in use, the pilot had an emergency override lever available with which to revert to direct control mode in flight.Lean and Chinn 1965, p. 7.

Another benefit of this engine location was ease of maintenance, as the engine could be readily accessed at ground level through dual clamshell-style doors; the entire engine could be changed in only two hours, and the radial engine was oriented backwards relative to a typical airplane installation, allowing more convenient access to engine accessories.The accessories for a radial engine were traditionally located on the side of the engine opposite the crankshaft; in a prop-powered airplane that used the more commonplace tractor configuration, the accessories were typically buried inside a cowling or nacelle, resulting in less convenient access than the reversed orientation used in the H-19. UH-19B rotor head The offset flapping hinges and hydraulic servos gave more positive flight control under differing loading conditions, isolated the flight controls from vibration, and lessened control forces; the H-19 could be flown with only two fingers on the cyclic control. The YH-19 prototypes featured a blunt aft fuselage and a single starboard-mounted horizontal tailplane with a small vertical fin at its outboard end.

A simple scheme for a zoom lens divides the assembly into two parts: a focusing lens similar to a standard, fixed-focal-length photographic lens, preceded by an afocal zoom system, an arrangement of fixed and movable lens elements that does not focus the light, but alters the size of a beam of light travelling through it, and thus the overall magnification of the lens system. Movement of lenses in an afocal zoom system In this simple optically compensated zoom lens, the afocal system consists of two positive (converging) lenses of equal focal length (lenses L1 and L3) with a negative (diverging) lens (L2) between them, with an absolute focal length less than half that of the positive lenses. Lens L3 is fixed, but lenses L1 and L2 can be moved axially in a particular non-linear relationship. This movement is usually performed by a complex arrangement of gears and cams in the lens housing, although some modern zoom lenses use computer-controlled servos to perform this positioning.

Due to Gus's small size, many of the servos needed to provide his animatronic functions are mounted externally, with the cables running through spring housings on their way up to his head.Delaware County Times article on filming Gus commercial Retrieved 2011-02-12 Gus, with his lovable, wise-cracking personality, gained some popularity with Pennsylvanians; however, the Pennsylvania Lottery would not offer plush replicas of Gus for sale despite customer requests because that organization believes that such a toy would advertise the lottery (a game which is restricted to adult play) to children. Gus has also appeared dressed in both Philadelphia Eagles and Pittsburgh Steelers uniforms with other similarly uniformed men in a licensed co-branding with those two National Football League teams, as certain instant games are branded for those teams. On February 22, 2012, the Pennsylvania Lottery announced that the campaign with Gus would be discontinued, so they could focus on a new campaign explaining how the PA Lottery benefits older Pennsylvanians, but after a nearly four-year hiatus, he returned on November 1, 2015 onwardsGus, Pa.'s 'second-most famous groundhog,' is back pushing lottery tickets Retrieved 2020-03-08.

H-19 at National Museum of the United States Air Force, showing unusual mounting of engine Major innovations implemented on the H-19 were the forward placement of the engine below the crew compartment and in front of the main cabin, the use of offset flapping hinges located nine inches (229 mm) from the center of the rotor, and the use of hydraulic servos for the main rotor controls. These features yielded an aircraft that was far more capable in a transport role than previous Sikorsky designs. The forward engine location placed the main cabin essentially in line with the main rotor's rotational axis and close to the aircraft center of gravity, making it easier to maintain proper weight and balance under differing loading conditions. The impetus for this design choice was the recent rejection of the Sikorsky XHJS by the U.S. Navy in favor of the tandem rotor Piasecki HUP Retriever; the Navy had strongly objected to the necessity to use ballast in the cabin-forward XHJS to maintain proper weight and balance, prompting Sikorsky to seek single-rotor design alternatives that did not require this.

The College motto is Bona Facite, usually translated as Do Good, and, while being a linguistic play on the name of St Boniface, is possibly taken from Chapter 35, Verse 15 of Jeremiah, "Misique ad vos omnes servos meos prophetas, consurgens diluculo mittensque, et dicens: Convertimini unusquisque a via sua pessima, et bona facite studia vestra: et nolite sequi deos alienos, neque colatis eos, et habitabitis in terra quam dedi vobis et patribus vestris: et non inclinastis aurem vestram, neque audistis me" (And I have sent to you all my servants the prophets, rising early, and sending and saying: Return ye every man from his wicked way, and make your ways good: and follow not strange gods, nor worship them, and you shall dwell in the land, which I gave you and your fathers: and you have not inclined your ear, nor hearkened to me). The College badge proclaims the school's origins. The cross of St Andrew represents the Old Cathedral Church of Plymouth, the Bishop's staff represents the patronage of St Boniface; and the cross keys of St Peter represent the Catholic Church, towards which the College owes its allegiance. The badge's blue background echoes the College's connections with the sea.
