Annex E, Acronyms for balanced cables, provides a system to specify the exact construction for both unshielded and shielded balanced twisted pair cables. It uses three letters - U for unshielded, S for braided shielding, and F for foil shielding - to form a two-part abbreviation in the form of xx/xTP, where the first part specifies the type of overall cable shielding, and the second part specifies shielding for individual cable elements. Common cable types include U/UTP (unshielded cable); U/FTP (individual pair shielding without the overall screen); F/UTP, S/UTP, or SF/UTP (overall screen without individual shielding); and F/FTP, S/FTP, or SF/FTP (overall screen with individual foil shielding).

Cross-section of cable with four unshielded twisted pairs Unshielded twisted pair (UTP) cables are found in many Ethernet networks and telephone systems. For indoor telephone applications, UTP is often grouped into sets of 25 pairs according to a standard 25-pair color code originally developed by AT&T; Corporation. A typical subset of these colors (white/blue, blue/white, white/orange, orange/white) shows up in most UTP cables. The cables are typically made with copper wires measured at 22 or 24 American Wire Gauge (AWG), with the colored insulation typically made from an insulator such as polyethylene or FEP and the total package covered in a polyethylene jacket.

His replacement was no better. Among other things, he obeyed to the letter Navy's order forbidding the use of unshielded radio receivers at sea. Since the Signal Corps receivers aboard the ship were unshielded and thus liable to radiate sufficiently to alert nearby enemy listeners, the men were forbidden to switch them on in order to hear orders from Army headquarters ashore. As a consequence, during a trip in the spring of 1944 from Milne Bay to Cairns, Australia (on naval orders), the crew failed to hear frantic Signal Corps radio messages to the Argosy Lemal ordering her to return at once to Milne Bay to make ready for a forthcoming Army operation.

The main issue determining the frequencies of power-line communication is laws to limit interference with radio services. Many nations regulate unshielded wired emissions as if they were radio transmitters. These jurisdictions usually require unlicensed uses to be below 500 kHz or in unlicensed radio bands. Some jurisdictions (such as the EU), regulate wire-line transmissions further.

Early Ethernet (10BASE-5 and 10BASE-2) used coaxial cable. Shielded twisted pair was used in IBM's Token Ring LAN implementation. In 1984, StarLAN showed the potential of simple unshielded twisted pair by using category 3 cable—the same cable used for telephone systems. This led to the development of 10BASE-T (and its twisted- pair successors) and structured cabling which is still the basis of most commercial LANs today.

It went through several revisions. The E/I connects to the CPU/keyboard with a 6-inch ribbon cable which is unshielded against RF interference and its card edge connector tends to oxidize due to its base metal contacts. This demands periodic cleaning with a pencil eraser in order to avoid spontaneous reboots, which contributes to its "Trash-80" sobriquet. Aftermarket connectors plated with gold solves this problem permanently.

26Al is only present today in the Solar System materials as the result of cosmic reactions on unshielded materials at an extremely low level. Thus, any original 26Al in the early Solar System is now extinct. To establish the presence of 26Al in very ancient materials requires demonstrating that samples must contain clear excesses of 26Mg /24Mg which correlates with the ratio of 27Al/24Mg. The stable 27Al is then a surrogate for extinct 26Al.

The power emitted in radioactive decay corresponding to one curie can be calculated by multiplying the decay energy by approximately 5.93 mW/MeV. A radiotherapy machine may have roughly 1000 Ci of a radioisotope such as caesium-137 or cobalt-60. This quantity of radioactivity can produce serious health effects with only a few minutes of close-range, unshielded exposure. Ingesting even a millicurie is usually fatal (unless it is a very short-lived isotope).

A dielectric resonator oscillator (DRO) is an electronic component that exhibits resonance of the polarization response for a narrow range of frequencies, generally in the microwave band. It consists of a "puck" of ceramic that has a large dielectric constant and a low dissipation factor. Such resonators are often used to provide a frequency reference in an oscillator circuit. An unshielded dielectric resonator can be used as a dielectric resonator antenna (DRA).

These had a greater number of available communications channels, which allowed the seeding of a larger sensor field without fear of signal interference. By 1971–1972 a new sensor with a commandable microphone (COMMMIKE III) and another with a vehicle ignition detector (EDET III, which could detect the unshielded ignition systems of gasoline engines) were introduced.Nalty, War Against Trucks, p. 84. In 1972 U.S. dollars the ADSID cost $619.00, the ACOUSID $1,452.00, and the engine detector $2,997.00.

This greatly reduced the cost of either constructing a new OR or retrofitting an old one. By using mobile units, the possibility of treating patients with IORT was no longer restricted to the availability of special shielded operating rooms, but could be done in regular unshielded ORs. Currently, the Mobetron, LIAC, and NOVAC-7 linear accelerators are improving patient care by delivering intraoperative radiation electron beam therapy to cancer patients during surgery. All three units are compact and mobile.

Various in-universe sources describe quantum torpedoes as roughly double the destructive power of standard photon torpedoes, putting their yield somewhere in excess of 100 megatons of TNT. In the DS9 episode "Paradise Lost", the USS Lakota was also stated to be carrying quantum torpedoes, although they were never used. Four of the USS Enterprise-E's quantum torpedoes destroyed an unshielded Borg sphere. The launcher appears on the 1701-E in Star Trek: Insurrection but is never fired.

For urban outdoor telephone cables containing hundreds or thousands of pairs, the cable is divided into small but identical bundles. Each bundle consists of twisted pairs that have different twist rates, as pairs having the same twist rate within the cable can still experience some degree of crosstalk. The bundles are in turn twisted together to make up the cable. Unshielded twisted pair cable with different twist rates UTP is also the most common cable used in computer networking.

Space radiation consists of high energy particles such as protons, alpha and heavier particles originating from such sources as galactic cosmic rays, energetic solar particles from solar flares and trapped radiation belts. Space station crew exposures will be much higher than those on Earth and unshielded astronauts may experience serious health effects if unprotected. Galactic cosmic radiation is extremely penetrating and it may not be possible to build shields of sufficient depth to prevent or control exposure.

Organocatalysis is a subfield of catalysis that explores the potential of organic small molecules as catalysts, particularly for the enantioselective creation of chiral molecules. One strategy in this subfield is the use of chiral secondary amines to activate carbonyl compounds. In this case, amine condensation with the carbonyl compound generates a nucleophilic enamine. The chiral amine is designed so that one face of the enamine is sterically shielded and so that only the unshielded face is free to react.

SynOptics Communications was founded in 1985 by Andrew K. Ludwick and Ronald V. Schmidt, both of whom worked at Xerox's Palo Alto Research Center (PARC). The most significant product that Synoptics produced was LattisNet (originally named AstraNet) in 1987. This meant that unshielded twisted-pair cabling already installed in office buildings could be re-utilized for computer networking instead of special coaxial cables. The star network topology made the network much easier to manage and maintain.

Cabling is in the form of an unshielded, three or five conductor cables, not longer than twenty meters, and a standardized four or five pin connector. The master and device pin assignment is based on the specifications in IEC 60947-5-2. For a master, two port classes are defined, port class A and port class B. Port class A uses M5, M8, or M12 connectors, with a maximum of four pins. Port class B uses only M12 connectors with 5 pins.

Twisted pair cabling is the most popular network cable and is often used in data networks for short and medium length connections (up to 100 meters or 328 feet). This is due to its relatively lower costs compared to optical fiber and coaxial cable. Unshielded twisted pair (UTP) cables are the primary cable type for telephone usage. In the late 20th century, UTPs emerged as the most common cable in computer networking cables, especially as patch cables or temporary network connections.
|
|
The network runs on a 4-twisted-pair cable of 100Ω 100 MHz CAT5E [1] or a flat cable with RS485 serial port, usually with a RJ-12 connector. A daisy-chain serial network topology is strongly recommended with no stubs. The recommended cable colour-coding is: Green/White pair = paralleled for GND Orange/White pair = paralleled for +12V Blue/White pair = blue for DATA+ and white for DATA- Brown/White pair = spare or shield if unshielded cable is used.
|
|
Once the heads are properly positioned and the appropriate head is selected, data is read or written serially through a set of pins in the data cable. The limited bandwidth of the data cable was not an issue at the time and is not the factor that limited the performance of the system. However, the unshielded cable can sometimes be susceptible to high levels of noise. The ST412 disk drive, among other improvements, added buffered seek capability to the interface.

Oil-fired ships were faster, and capable of reaching s while coal-fired ships were slower. The Arras-class were armed with two single /55 Modèle 1910 guns in unshielded mounts mounted at the bow and stern. Secondary armament consisted of a single /62.5 Modèle 1908 gun on a central high-angled mount as anti-aircraft artillery. Initially armed with four single /80 Modèle 1914 machine guns, these were later replaced with four single 13.2 mm/76 Modèle 1929 machine guns.

Copper wire is currently the most commonly used type of physical media due to the abundance of copper in the world, as well as its ability to conduct electrical power. Copper is also one of the cheaper metals which makes it more feasible to use. Most copper wires used in data communications today have eight strands of copper, organized in unshielded twisted pairs, or UTP. The wires are twisted around one another because it reduces electrical interference from outside sources.

Curie worked extensively with radium, which decays into radon,Health Physics Society, "Did Marie Curie die of a radiation overexposure?" along with other radioactive materials that emit beta and gamma rays. However, Curie also worked with unshielded X-ray tubes during World War I, and analysis of her skeleton during a reburial showed a relatively low level of radioisotope burden. The Russian dissident Alexander Litvinenko's 2006 murder by radiation poisoning is thought to have been carried out with polonium-210, an alpha emitter.

As a result, later models had a cooling fan integrated into the main case. Another example of rumour was the suggestion that there were issues with the 'unshielded' power supply in the monitor affecting an optional hard drive that could be installed at the back of the base unit and further that this would be solved by taping tin foil or aluminum foil over the back of the base unit or the bottom of the monitor to shield the hard drive.

Csa climates are mainly found around the Mediterranean Sea, southwestern Australia, southwestern South Africa, sections of Central Asia, northern sections of Iran and Iraq, the interior of northern California west of the Sierra Nevada, and inland areas of southern Oregon west of the Cascade Mountains. Southern California's coasts also experience hot summers due to the shielding effect of the Channel Islands. However, unshielded areas of that coastline can have warm-summer Mediterranean climates with hot-summer areas just a few kilometres inland.

Ethernet over twisted pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers. Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and its successors 100BASE-TX, 1000BASE-T and 10GBASE-T, supporting speeds of 10 and 100 megabit per second, then 1 and 10 gigabit per second respectively.

He is then recaptured. Gordon knows that the only hope of saving X-7 is to lower its interior temperature to below zero degrees. The fungus inside X-7 dies, but it's growing on the outside of the space station as well. No one can understand why the fungus is spreading on X-7's exterior until one of Knowland's staff officers says that it must be due to the "high temperatures generated by the unshielded blazing sun" beating down on X-7.

For power, the system includes batteries for energy storage, along with a solar array rated to sustain the mission for 100 days. Altogether, the instrument is expected to draw only 380 watts from a 28-volt supply, thanks to a very careful choice of energy-efficient electronics. In near-vacuum conditions, significant precautions must be taken against coronal discharges between unshielded electronics operating at as low as 100 volts. This is mitigated by encasing all relevant electronics in a lightweight dielectric compound, such as plaster.

Various button combinations control the Delta Saber's speed, allowing the craft to boost to great speeds with afterburners, coast on inertia without power, or match speed with a target. Certain maneuvers require the expenditure of shield energy, which protects starships from damage; an unshielded vessel under attack suffers damage to its armor. A ship is destroyed when its armor is depleted. On starting a new campaign, the player receives a small selection of missiles, guns, beams, and bombs to mount on his or her ship.

Most Dell laptop computers have a special external power supply (PSU) which cannot be replaced by a third-party universal supply. The PSU has what's called UniqueWare™ Add-Only Memory, known under type DS2501. It is a parasitic power circuit memory chip connected to the center identification pin in the plug, via a 2m long unshielded wire alongside the PSU cable. This chip produces a special signal using a 1 wire communication protocol known as "1-wire" in identifying the PSU as an original Dell PSU.

The presence of such no man's lands in Thessaly indicates that there may have been conflict and a need for defensive fortifications. The walls at both settlements included baffle gates, a classic characteristic of other fortified sites during this time period in Greece. This feature forces invaders to expose their flanks by requiring them to turn left, exposing their unshielded right side. Sesklo had one such gate on the western side, which was not protected by the steep ravine located on the eastern side of the settlement.

Each transceiver had two, 3-pin, Mini-DIN ports, and a cable to connect to the Mac's DE-9 serial connector. Later, when the Mac Plus introduced the 8-pin Mini-DIN serial connector, transceivers were updated as well. A variation of LocalTalk called PhoneNet was introduced by Farallon Computing. It used standard unshielded side-by-side telephone wire, with six-position modular connectors (same as the popular RJ11 telephone connectors) connected to a PhoneNet transceiver, instead of the expensive, shielded, twisted-pair cable.

During the early 1980s most networks used coaxial cable as the primary form of premises cabling in Ethernet implementations. In 1985 SynOptics shipped its first hub for fiber optics and shielded twisted pair. SynOptics' co-founder, Engineer Ronald V. Schmidt, had experimented with a fiber-optic variant of Ethernet called Fibernet II while working at Xerox PARC, where Ethernet had been invented. In January 1987 SynOptics announced intentions to manufacture equipment supporting 10 megabits/sec data transfer rates over unshielded twisted pair, telephone wire.

Curie was also exposed to X-rays from unshielded equipment while serving as a radiologist in field hospitals during the war. Although her many decades of exposure to radiation caused chronic illnesses (including near-blindness due to cataracts) and ultimately her death, she never really acknowledged the health risks of radiation exposure.Denise Grady (6 October 1998), A Glow in the Dark, and a Lesson in Scientific Peril The New York Times; accessed 21 December 2016. She was interred at the cemetery in Sceaux, alongside her husband Pierre.

Note the automatically inflating peripheral hood seal Basing their design on the Whirlwind, Westland developed the Welkin high altitude interceptor, Penrose flying the prototype in November 1942. He described how the cabin was 'like sitting in an oven' due to the unshielded cabin pressurisation blowers. He developed pneumonia in early 1943 which he attributed to the extreme changes in temperature on leaving the Welkins cabin drenched in sweat and the bitter wind across the airfield. He survived thanks to the recently discovered M&B; drug.

In 1954 Gretsch began plans to produce the first Chet Atkins-endorsed guitar model, the Gretsch 6120. Atkins recorded much of his music of the 1950s with the Echosonic, and had serious hum problems caused by the single-coil pickups and an unshielded transformer in the amplifier. Butts finally connected two single-coil pickups serially and out of phase, creating the first humbucker. Butts did not receive a patent until later, when it became the Gretsch Filter'Tron, and Gibson is often credited with developing the first humbucker.

Henry Ott consultants explained a simple setup on measuring common mode current by putting a high frequency current clamp from Fischer Custom Communications on multi-conductors and connect it to a spectrum analyzer. It is assumed that all of the common mode current flowing on those multiconductors will travel using another return path that is unknown. With a known transfer impedance, the common mode current measured from the multi-conductors can be determined by looking at the voltage shown at the spectrum analyzer. That measurement technique can work on both shielded and unshielded cables.

In Eastern Europe, Russia, and third world countries, many utility poles still carry bare communication wires mounted on insulators not only along railway lines, but also along roads and sometimes even in urban areas. Errant traffic being uncommon on railways, their poles are usually less tall. In the United States electricity is predominately carried on unshielded aluminum conductors wound around a solid steel core and affixed to rated insulators made from glass, ceramic, or poly. Telephone, CATV, and fibre optic cables are generally attached directly to the pole without insulators.

Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points. An appropriately sized conductive sleeve called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit. Jumpers must be electrically conducting; they are usually encased in a non-conductive block of plastic for convenience. This also avoids the risk that an unshielded jumper will accidentally short out something critical (particularly if it is dropped on a live circuit).

Its estimated airspeed at was Mach 4.2. The SLAM program was scrapped on July 1, 1964. By this time serious questions about its viability had been raised, such as how to test a device that would emit copious amounts of radioactive exhaust from its unshielded reactor core in flight, as well as its efficacy and cost. ICBMs promised swifter delivery to targets, and because of their speed (the Thor could reach its target in 18 minutes, whereas the SLAM would take much longer) and trajectory, were considered virtually unstoppable.

The main battery of the Nelson-class ships consisted of nine breech-loading (BL) guns in three triple-gun turrets forward of the superstructure. Designated 'A', 'B' and 'C' from front to rear, 'B' turret superfired over the others. Their secondary armament consisted of a dozen BL Mk XXII guns in twin-gun turrets aft of the superstructure, three turrets on each broadside. Their anti-aircraft (AA) armament consisted of six quick-firing (QF) Mk VIII guns in unshielded single mounts and eight QF 2-pounder () guns in single mounts.

Lyon Warship Vol. 1 No. 2, p. 57.Brown 2010, p. 160. It was originally intended that the Bristol class would be fitted with a main gun armament of unshielded guns, but the need to counter German light cruisers (such as the ), which were armed with ten guns that outranged British 4-inch guns, resulted in the new class's armament being revised. They had two BL 6-inch (152 mm) Mk XI naval guns mounted on the ships' centreline fore and aft, with ten BL 4-inch Mk VII guns in waist mountings.

During Overwatchs 2016 holiday event, a new game mode centered on Mei was added, called "Mei's Snowball Offensive", with each player controlling Mei. Her ice shield and ice wall abilities were left unchanged, but her blaster was replaced with a single-shot snowball thrower that would be an instant kill if it hit an unshielded opponent. The blaster could be reloaded by finding a patch of snow that randomly appeared on the map. Mei's ultimate ability enabled her to fire the snowball blaster several times without reloading for a short period of time.

The number of MOPPs a network isolator provides will be stated in the certification of the device. These are achieved by a combination of clearance and creepage distances, and the breakdown voltage of the insulating materials. Although requirements on breakdown voltage levels are 1.5 kilovolts for one MOPP, and 4 kilovolts for two MOPPs, the number of MOPPs actually provided cannot be derived from the breakdown voltage alone. Network connections made with unshielded cables are occasionally used as a form of isolation, in that no shield connection exists between the device and the network.

In structured cabling, crosstalk refers to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel. Signals traveling through adjacent pairs of wire create magnetic fields that interact with each other, inducing interference in the neighboring pair. The pair causing the interference is called the “disturbing pair”, while the pair experiencing the interference is the “disturbed pair”. ;Near-end crosstalk (NEXT): NEXT is a measure of the ability of a cable to reject crosstalk, so the higher the NEXT value, the greater the rejection of crosstalk at the local connection.

'Category 3 cable, commonly known as ' or station wire, and less commonly known as VG or voice-grade (as, for example, in 100BaseVG), is an unshielded twisted pair (UTP) cable used in telephone wiring. It is part of a family of standards defined jointly by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) and published in TIA/EIA-568-B. Although designed to reliably carry data up to 10 Mbit/s, modern data networks run at much higher speeds, and or better cable is generally used for new installations.

Category 4 cable (Cat 4) is a cable that consists of four unshielded twisted pair (UTP) copper wires supporting signals up to 20 MHz. It is used in telephone networks which can transmit voice and data up to 16 Mbit/s.CCNA: Network Media Types For a brief period it was used for some token ring, 10BASE-T, and 100BASE-T4 networks, but was quickly superseded by Category 5 cable. It is no longer common or used in new installations and is not recognized by the current version of the TIA/EIA-568 data cabling standards.

Speaker DIN line socket (left) and plug (right) A polarised two-pin unshielded connector, designed for connecting a loudspeaker to a power amplifier (or other device; many of the earlier shoebox style tape recorders used them), is known as the DIN 41529 loudspeaker connector. It exists as a panel-mounting female version, and line-mounted male and female versions. The male version has a central flat pin, and circular pin mounted off-centre. The circular pin is connected to the positive line (red) while the spade is connected to the negative line (black).

The ISO/IEC TR 29125 and Cenelec EN 50174-99-1 draft standards outline the cable bundle temperature rise that can be expected from the use of 4PPoE. A distinction is made between two scenarios: # bundles heating up from the inside to the outside, and # bundles heating up from the outside to match the ambient temperature. The second scenario largely depends on the environment and installation, whereas the first is solely influenced by the cable construction. In a standard unshielded cable, the PoE-related temperature rise increases by a factor of 5.

The Cathlamet is infamous in Puget Sound as it has on several occasions struck ferry docks while attempting to dock—occasionally referred to by Whidbey Island residents as the Crashlamet. The problem was eventually traced to the computer that controls the pitch of the props, which because of a large amount of unshielded wiring, would short out a couple of signal lines causing the props to re-angle for full propulsion, instead of reversing. The computer system was eventually replaced in the early 2000s, and since then, the Cathlamet has not struck another dock.

While power lines are not an electrocution hazard for birds, older poles that are unshielded can be dangerous. D12's remains were turned over to the Fish and Wildlife Service, in accordance with the Eagle feather law. Because the bald eagle is a sacred bird in some North American cultures, D12's feathers are being distributed to qualified Native Americans for use in religious ceremonies through the National Eagle Repository. From Raptor Resource Project: We are sorry to announce that Four, the single remaining bird from the 2014 Decorah alumni to remain in the wild, was electrocuted on Tuesday, March 2, 2015.

The twist rate (also called pitch of the twist, usually defined in twists per metre) makes up part of the specification for a given type of cable. When nearby pairs have equal twist rates, the same conductors of the different pairs may repeatedly lie next to each other, partially undoing the benefits of twisting. For this reason it is commonly specified that, at least for cables containing small numbers of pairs, the twist rates must differ. In contrast to shielded or foiled twisted pair (typically S/FTP or F/UTP cable shielding), UTP (unshielded twisted pair) cable is not surrounded by any shielding.

An E1 link operates over two separate sets of wires, usually unshielded twisted pair (balanced cable) or using coaxial (unbalanced cable). A nominal 3 volt peak signal is encoded with pulses using a method avoiding long periods without polarity changes. The line data rate is 2.048 Mbit/s (full duplex, i.e. 2.048 Mbit/s downstream and 2.048 Mbit/s upstream) which is split into 32 timeslots, each being allocated 8 bits in turn. Thus each timeslot sends and receives an 8-bit PCM sample, usually encoded according to A-law algorithm, 8,000 times per second (8 × 8,000 × 32 = 2,048,000).

Because the basis of almost all semiconductor electronics is the p-n junction, an NLJD is correspondingly capable of detecting almost any unshielded electronic device containing semiconductors, whether the electronics are actively powered or not. In its basic form, an NLJD can also detect things that are not themselves electronic in nature, so the use of the device requires a modicum of skill and experience. For example, a rusty nail inside a wall can give a false positive. For this reason, most modern NLJDs examine the ratio between the second and the third harmonic of the illumination frequency.

The light at Presque Isle was not installed with any sort of flashing system, though the option was left available. Often, boats are able to distinguish between two different lights by a Flashing beacon. Either the beacon itself would rotate, and thus illuminate 360° around the lighthouse, or a blinder with only a small portion unshielded would rotate around the lamp, exposing the bright light for only a few seconds. The rotation was controlled by heavy weights that would slowly sink due to gravity. Every few hours the lightkeeper would “wind up” the rotating beacon or blinder.

BroadR-Reach is a Broadcom point-to- point Ethernet PHY technology, adopted by the OPEN Alliance as the OPEN Alliance BroadR-Reach PHY (OABR PHY), that specifies a PHY operating full- duplex over one pair of unshielded twisted pair (UTP) cable at 100 Mb/s.Broadcom developed this as 100BASE-T1, which in turn has been adopted under IEEE 803.2bw. This has been adapted for transmission on other cable formats including Coax. [3] As part of the BroadR-Reach standard the digital signal processor (DSP) uses a highly optimized scrambler when compared to the scrambler used in 100BASE-TX.

The AS-Interface is a single-master system, this means a master device exchanges the input and output data with all configured devices. The transmission medium is an unshielded two-wire yellow flat cable. The cable is used for signal transmission and at the same time for power supply (30 V). The communication electronics and participants with low power requirements, like light beams, can be powered directly. Consumers with a higher energy requirement, such as valve terminals, can use a separate, usually black flat cable for power supply (30 V). The sensors or actuators are often connected via the so-called piercing technology.

Images show retiarii stabbing downward at the secutor's unshielded legs or stabbing down at the helmet in an attempt to poke through an eyehole. The trident itself was too weak to pierce the metal, although a skull found at Ephesus, Turkey, dating to CE 200 to 300 shows that a trident strike to the head could be fatal on a bareheaded opponent.Follain 1. The secutor's helmet was rounded and free of protrusions to avoid snaring the net or being caught in the trident's prongs, but attacks on it forced the secutor to duck or hide behind his shield.

On UV radiation, a 2014 report concludes that "[T]he Martian UV radiation environment is rapidly lethal to unshielded microbes but can be attenuated by global dust storms and shielded completely by < 1 mm of regolith or by other organisms." In addition, laboratory research published in July 2017 demonstrated that UV irradiated perchlorates cause a 10.8-fold increase in cell death when compared to cells exposed to UV radiation after 60 seconds of exposure. The penetration depth of UV radiation into soils is in the sub-millimeter to millimeter range and depends on the properties of the soil.

For defense against torpedo boats, Brennus was equipped with a suite of quick-firing guns, the largest of which were four 50-caliber Canon de Modèle 1891 guns in single unshielded mounts on the fore and aft superstructure. Their shells had a muzzle velocity of which gave them a range of . The suite was rounded out by fourteen 40-caliber Modèle 1885 guns and fourteen Modèle 1885 Hotchkiss guns, of which six of the latter were 5-barrel revolver cannon. All of these guns were positioned in the fighting tops on the military masts and in the superstructure.

Hall, Weapons and Warfare, 186; Oman, Art of War, 235. Hall notes that the artillery "was kept well back... and officers on both sides took care not to expose unshielded infantry to its fire". The first phase of the battle, including the Imperial advance, the rout of the Florentine cavalry, the division of the landsknechts, and the advance and retreat of the Spanish heavy cavalry. The skirmishing finally came to an end when it seemed that Imperial cavalry would attack the French arquebusiers in the flank; Montluc then requested assistance from Des Thermes, who advanced with his entire force of light cavalry.

Early experiments with star topologies (called "Fibernet") using optical fiber were published by 1978. Shared cable Ethernet is always hard to install in offices because its bus topology is in conflict with the star topology cable plans designed into buildings for telephony. Modifying Ethernet to conform to twisted pair telephone wiring already installed in commercial buildings provided another opportunity to lower costs, expand the installed base, and leverage building design, and, thus, twisted-pair Ethernet was the next logical development in the mid-1980s. Ethernet on unshielded twisted-pair cables (UTP) began with StarLAN at 1 Mbit/s in the mid-1980s.

At the time Fleischman worked as a radiographer, not only were x-ray tubes unshielded, it was common for operators place their own hands in front of their fluoroscope to check exposures. In addition, Fleischman would often expose herself to X-rays to show patients that the procedure was painless. By 1903, the cumulative effects of seven years of unprotected X-ray exposures and twelve-hour workdays began to appear as X-ray dermatitis on her hands. She attributed this irritation to the chemicals used in developing photographic plates. In early 1904, the dermatitis progressed to the point where she sought medical attention.

In order to keep the size of the confinement building down, the early Magnox designs placed the heat exchanger for the CO2 gas outside the dome, connected through piping. Although there were strengths with this approach in that maintenance and access was generally more straightforward, the major weakness was the radiation 'shine' emitted particularly from the unshielded top duct. The Magnox design was an evolution and never truly finalised, and later units differ considerably from earlier ones. As neutron fluxes increased in order to improve power densities problems with neutron embrittlement were encountered, particularly at low temperatures.

Customers connect to the DSLAM through ADSL modems or DSL routers, which are connected to the PSTN network via typical unshielded twisted pair telephone lines. Each DSLAM has multiple aggregation cards, and each such card can have multiple ports to which the customers' lines are connected. Typically a single DSLAM aggregation card has 24 ports, but this number can vary with each manufacturer. The most common DSLAMs are housed in a telco-grade chassis, which are supplied with (nominal) 48 volts DC. Hence a typical DSLAM setup may contain power converters, DSLAM chassis, aggregation cards, cabling, and upstream links.

The German S-mine (Schrapnellmine, Springmine or Splittermine in German), also known as the "Bouncing Betty" on the Western Front and "frog-mine" on the Eastern Front, is the best-known version of a class of mines known as bounding mines. When triggered, these mines are launched into the air and then detonated at about from the ground. The explosion projects a lethal spray of shrapnel in all directions. The S-mine was an anti-personnel mine developed by Germany in the 1930s and used extensively by German forces during World War II. It was designed to be used in open areas against unshielded infantry.

Other cask designs orient the steel cylinder vertically on a concrete pad at a dry cask storage site and use both metal and concrete outer cylinders for radiation shielding. Currently there is no long term permanent storage facility; dry cask storage is designed as an interim safer solution than spent fuel pool storage. Some of the cask designs can be used for both storage and transportation. Three companies – Holtec International, NAC International and Areva-Transnuclear NUHOMS – are marketing Independent Spent Fuel Storage Installations (ISFSI's) based upon an unshielded multi-purpose canister which is transported and stored in on-site vertical or horizontal shielded storage modules constructed of steel and concrete.

Insulation displacement connectors are usually used with small conductors for signal purposes and at low voltage. Power conductors carrying more than a few amperes are more reliably terminated with other means, though "hot tap" press-on connectors find some use in automotive applications for additions to existing wiring. A common example is the multi-conductor flat ribbon cable used in computer disk drives; to terminate each of the many (approximately 40) wires individually would be slow and error-prone, but an insulation displacement connector can terminate all the wires in a single action. Another very common use is so-called punch-down blocks used for terminating unshielded twisted pair wiring.

Metallic path facility (MPF) are the unshielded twisted pair of copper wires that run from a main distribution frame (MDF) at a local telephone exchange to the customer. In this variant, both broadband and voice (baseband) services, together potentially with a video on demand service, are provided to the end user by a single communications provider. MPF services are typically delivered through use of an MSAN. Shared metallic path facility (SMPF) is based on the same technology as MPF, but denotes a variant whereby an Internet Service Provider (ISP) provides a broadband service to the end user but hands the voice (baseband) service back to the PTT/ILEC.

Traditional automotive networks such as CAN, LIN, FlexRay, MOST were unable to meet the higher data rate requirements of emerging automotive applications such as advanced driver assistance systems (ADAS), Infotainment or fast update of various ECUs in vehicles. This led BMW to investigate new standard based networking technologies such as Ethernet in 2004. Standard 100BASE-TX Fast Ethernet met automotive requirements for higher bandwidth and also provided flexibility in networking topology but it had limitations in meeting the automotive EMC requirements. In collaboration with Broadcom, BMW customized the BroadR-Reach Ethernet technology to meet automotive EMC requirements over a single unshielded twisted pair cable.

The C-Bus System can be used to control lighting and other electrical systems and products automatically or via remote control and can also be interfaced to a home security system, AV products or other electrical items. The C-Bus system is available in a wired version and a wireless version, with a gateway available to allow messages to be sent between wired and wireless networks. The wired C-Bus system uses a standard category 5 UTP (Unshielded Twisted Pair) cable as its network communications cable and does not require end of line termination. Clipsal manufactures a specific category 5 cable for use within electrical distribution panels.

A red camera filter was used to make the blue sky photograph very dark on the black-and-white film, but the result is still far from the ideal starry black. Bits of scrubby vegetation can be seen in the background of some shots. No attempt is made to convince the viewer that the Moon is an airless void where humans would weigh one-sixth their normal Earth weight. When one of the space-suited astronauts is forced into direct sunlight, unshielded from its intensity, he bursts into flames, despite the lack of an external oxygen atmosphere; in seconds he is reduced to a skeleton.

Most of the space elevator structure would lay inside the Van Allen radiation belt, and the space elevator would run through the Van Allen belts. This is not a problem for most freight, but the amount of time a climber spends in this region would cause radiation poisoning to any unshielded human or other living things. The inner belt would have to be crossed, where (behind a shield of 3 mm of aluminium) the dose rate can reach 465 mSv/h. The geostationary orbit (at 35,786 km) would still be inside the outer belt, with dose rates still in the 20-25 mSv/h range.

Photoengraving is a process that uses a light-sensitive photoresist applied to the surface to be engraved to create a mask that shields some areas during a subsequent operation which etches, dissolves, or otherwise removes some or all of the material from the unshielded areas. Normally applied to metal, it can also be used on glass, plastic and other materials. A photoresist is selected which is resistant to the particular acid or other etching compound to be used. It may be a liquid applied by brushing, spraying, pouring or other means and then allowed to set, or it may come in sheet form and be applied by laminating.

S/FTP cable Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6\. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the quality of the twists to protect from EMI. This involves a tight twist and carefully controlled design. Cables with individual shielding per pair such as category 7 rely mostly on the shield and therefore have pairs with longer twists. The Category 7 cable standard was ratified in 2002 to allow 10 gigabit Ethernet over 100 m of copper cabling.

An 8P8C modular plug not yet crimped onto a cable An 8P8C modular jack The 8 position 8 contact (8P8C) connector is a modular connector commonly used to terminate twisted pair and multi-conductor flat cable. These connectors are commonly used for Ethernet over twisted pair, registered jacks and other telephone applications, RS-232 serial communication using the TIA/EIA-568 and Yost standards, and other applications involving unshielded twisted pair, shielded twisted pair, and multi-conductor flat cable. An 8P8C modular connection consists of a male plug and a female jack, each with eight equally-spaced contacts. On the plug, the contacts are flat metal bars positioned parallel to the connector body.

Because 8b/10b encoding uses 10-bit symbols to encode 8-bit words, some of the possible 1024 (10 bit, 210) codes can be excluded to grant a run-length limit of 5 consecutive equal bits and to achieve the difference of the count of zeros and ones to be no more than two. Some of the 256 possible 8-bit words can be encoded in two different ways. Using these alternative encodings, the scheme is able to achieve long-term DC-balance in the serial data stream. This permits the data stream to be transmitted through a channel with a high-pass characteristic, for example Ethernet's transformer-coupled unshielded twisted pair or optical receivers using automatic gain control.

Sagittarius, three forms of light pollution are present: skyglow, glare, and light trespass. Light used for all purposes in the outdoor environment contributes to skyglow, by sometimes avoidable aspects such as poor shielding of fixtures, and through at least partially unavoidable aspects such as unshielded signage and reflection from intentionally illuminated surfaces. Some of this light is then scattered in the atmosphere back toward the ground by molecules and aerosols (see ), and (if present) clouds, causing skyglow. Research indicates that when viewed from nearby about half of skyglow arises from direct upward emissions, and half from reflected, though the ratio varies depending on details of lighting fixtures and usage, and distance of the observation point from the light source.

Five modern technetium-99m generators The first technetium-99m generator, unshielded, 1958. A Tc-99m pertechnetate solution is being eluted from Mo-99 molybdate bound to a chromatographic substrate A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99mTc of technetium from a decaying sample of molybdenum-99. 99Mo has a half-life of 66 hours and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life of only 6 hours, inconvenient for transport) is extracted and used for a variety of nuclear medicine diagnostic procedures, where its short half- life is very useful.

MOST50 doubles the bandwidth of a MOST25 system and increases the frame length to 1024 bits. The three established channels (control message channel, streaming data channel, packet data channel) of MOST25 remain the same, but the length of the control channel and the sectioning between the synchronous and asynchronous channels are flexible. Although MOST50 is specified to support both optical and electrical physical layers, the available MOST50 Intelligent Network Interface Controllers (INICs) only support electrical data transfer via a three copper conductor configuration; consisting of an Unshielded Twisted Pair (UTP) set and a single additional control line. The additional control line is connected to each MOST50 network device in a parallel "single shared bus" configuration.

Hanriot's 15-year-old son Marcel became the youngest holder of a pilot's certificate, and joined his father's pilots as a competition flyer. René Hanriot then withdrew from competition flying himself and concentrated on constructing aircraft. Hanriot's 1911 military two-seater was passed over at the French military trials, among other reasons because its fuselage was so slender that the crew were completely unshielded. It was obsolete and never had a serious chance against contemporary Nieuport, Morane-Saulnier and Deperdussin types. Nieuport's former chief engineer Alfred Pagny designed the 1912 Hanriot, and the Nieuport influence was clearly visible, but it failed to gain any orders at the 1912 military trials and attempts to sell them were unsuccessful.

The protective apron is of a state-of-the-art bismuth-antimony bilayer composition and offers 0.5mm lead-equivalent protection with a small overlap area of 1mm in the front. The visor is made up of a transparent lead-acrylic material and is designed to provide full head and eye protection, areas that are many times exposed in users of standard lead apron solutions. It is positioned at an angle so that it blocks most of the radiation coming from underneath and allows the physician to wear unshielded prescription glasses while performing procedures. The thyroid collar is unique in the sense that it is integrated into the protective apron component and is flush with the bottom side of the protective visor.

The standard defines categories of unshielded twisted pair cable systems, with different levels of performance in signal bandwidth, insertion loss, and cross-talk. Generally increasing category numbers correspond with a cable system suitable for higher rates of data transmission. Category 3 cable was suitable for telephone circuits and data rates up to 16 million bits per second. Category 5 cable, with more restrictions on attenuation and cross talk, has a bandwidth of 100 MHz.William Stallings Knowing UTP wiring basics can boost local net performance, Network World 9 July 1996, page 29 The 1995 edition of the standard defined categories 3, 4, and 5. Categories 1 and 2 were excluded from the standard since these categories were only used for voice circuits, not for data.

76, 80 Vanguards starboard aft side, showing her rear 12-inch gun turret and anti- torpedo net booms, around 1914 The St Vincent class was equipped with ten breech-loading (BL) Mk XI guns in five twin-gun turrets, three along the centreline and the remaining two as wing turrets. The centreline turrets were designated 'A', 'X' and 'Y', from front to rear, and the port and starboard wing turrets were 'P' and 'Q' respectively. The secondary, or anti-torpedo boat armament, comprised twenty BL Mk VII guns. Two of these guns were each installed on the roofs of the fore and aft centreline turrets and the wing turrets in unshielded mounts, and the other ten were positioned in the superstructure.

The shape and dimensions of an 8P8C modular connector are specified for U.S. telephone applications by the Administrative Council for Terminal Attachment (ACTA) in national standard ANSI/TIA-1096-A. This standard does not use the short term 8P8C and covers more than just 8P8C modular connectors, but the 8P8C modular connector type is the eight position connector type described therein, with eight contacts installed. The international standard is ISO-8877. For data communication applications (LAN, structured cabling), International Standard IEC 60603 specifies in parts 7-1, 7-2, 7-4, 7-5, and 7-7 not only the same physical dimensions, but also high-frequency performance requirements for shielded and unshielded versions of this connector for frequencies up to 100, 250 and 600 MHz, respectively.

A protection factor of at least 40 means that the radiation shielding provided by the shelter reduces the radiation dose experienced by at least 40 times that which would be experienced outside the shelter with no shielding. "Protection factor" is equivalent to the modern term "dose reduction factor". rads, this is a simplistic model (Gaussian) of a wind-blown fallout map, which depicts the unshielded ground level fallout gamma ray dose and dose rate contours expected to follow a 2 megaton land surface burst detonation, with 1 megaton of the yield coming from fission reactions. Because of radioactive decay, the dose rate contours (on the right) contract after fallout has arrived, but the total absorbed dose contours (left) continue to grow.

The original USB 1.0 specification, which was introduced in January 1996, defined data transfer rates of 1.5 Mbit/s Low Speed and 12 Mbit/s Full Speed. Draft designs had called for a single-speed 5 Mbit/s bus, but the low speed was added to support low-cost peripherals with unshielded cables, resulting in a split design with a 12 Mbit/s data rate intended for higher-speed devices such as printers and floppy disk drives, and the lower 1.5 Mbit/s rate for low data rate devices such as keyboards, mice and joysticks. Microsoft Windows 95, OSR 2.1 provided OEM support for the devices in August 1997. The first widely used version of USB was 1.1, which was released in September 1998.

Intel X540-T2 10GBASE-T dual port NIC 10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to . Category 6a is required to reach the full distance of and category 6 may reach a distance of depending on the quality of installation, determined only after re-testing to 500 MHz. 10GBASE-T cable infrastructure can also be used for 1000BASE-T allowing a gradual upgrade from 1000BASE-T using autonegotiation to select which speed to use. Due to additional line coding overhead, 10GBASE-T has a slightly higher latency in comparison to most other 10GBASE variants, in the range 2 to 4 microseconds compared to 1 to 12 microseconds on 1000BASE-T (depending on packet size).

In pursuit of the carriers of 22Ne in the sludge produced by chemical destruction of some meteorites, carrier grains in micron size, acid-resistant ultra-refractory materials (e.g. C, SiC) were found by E. Anders & the Chicago group. The carrier grains were clearly shown to be circumstellar condensates from earlier stars and often contained very large enhancements in 26Mg/24Mg from the decay of 26Al with 26Al/27Al sometimes approaching 0.2 These studies on micron scale grains were possible as a result of the development of surface ion mass spectrometry at high mass resolution with a focused beam developed by G. Slodzian & R.Castaing with the CAMECA Co. The production of 26Al by cosmic ray interactions in unshielded materials is used as a monitor of the time of exposure to cosmic rays.

Humbucker pickups are inherently low noise because the interference is significantly reduced via phase cancellation, however the Victory MV's have additional shielding connected to ground with the use of special electrically conductive black paint in the routed out area under the pickguard. Truly silent when it should be. The coil tap switch in the up position is humbucker; in the down position is single coil, indistinguishable from traditional unshielded single coils minus the noise. Victory MVs are totally immune from "Strat-Itis" (simultaneous multiple discordant frequency syndrome) In some single-coil pickups, strat-Itis is an annoying out-of-tune harmonic, oscillating/warbling /shriek/dissonant sound. Gibson had established business agreements for over 100 years with the best wood suppliers in the world, and Gibson Luthiers had first pick to craft the Victory MV's.

Category 1 cable, also known as Cat 1, Level 1, or voice-grade copper, is a grade of unshielded twisted pair cabling designed for telephone communications, and at one time was the most common on-premises wiring. The maximum frequency suitable for transmission over Cat 1 cable is 1 MHz,Meyers; Page 69. but Cat 1 is not currently considered adequate for data transmission (Though it was at one time used for that purpose on the Apple Macintosh starting in the late 80's in the form Farallon Computing's//NetTopia's PhoneNet, an implementation of Apple's LocalTalk networking hardware standard.)Carpenter; Page 231. Although not an official category standard established by TIA/EIA, Category 1 has become the de facto name given to Level 1 cables originally defined by Anixter International, the distributor.

In 1986 M/A-COM, Inc. sold the Cable Home Group to General Instrument Corporation. CommScope became a division of General Instrument. In 1990 CommScope opened a new manufacturing facility in Claremont, North Carolina, to answer the increased demand for unshielded twisted pair (copper telephone wiring), television receive-only cables (used for consumer satellite reception) and personal computer cables. In 1997 General Instrument split into three independent, publicly traded companies, one of which was CommScope. In July 1997 Drendel rang the bell at the New York Stock Exchange to announce CommScope going public. In 2000 CommScope opened its new global headquarters in Hickory, North Carolina. In 2004 CommScope acquired Avaya's Connectivity Solutions business and inherited the SYSTIMAX brand, a company perhaps best known for its enterprise cabling systems.

The U.S. is a notable exception, permitting limited-power wide-band signals to be injected into unshielded wiring, as long as the wiring is not designed to propagate radio waves in free space. Data rates and distance limits vary widely over many power-line communication standards. Low-frequency (about 100–200 kHz) carriers impressed on high-voltage transmission lines may carry one or two analog voice circuits, or telemetry and control circuits with an equivalent data rate of a few hundred bits per second; however, these circuits may be many miles long. Higher data rates generally imply shorter ranges; a local area network operating at millions of bits per second may only cover one floor of an office building, but eliminates the need for installation of dedicated network cabling.

When the loop is disconnected, the on-premises wiring is isolated from the telephone network and the customer may directly connect a telephone to the network via the jack to assist in determining the location of a wiring fault. In most cases, everything from the central office to and including the demarcation point is owned by the carrier and everything past it is owned by the property owner. As the local loop becomes upgraded, with fiber optic and coaxial cable technologies sometimes replacing the original unshielded twisted pair to the premises, the demarcation point has grown to incorporate the equipment necessary to interface the original premises POTS wiring and equipment to the new communication channel. Demarcation points on houses built prior to the Bell System divestiture usually do not contain a test jack.

A bilingual cable allows the connection of older devices to the newer port. In 2003, Apple was the first to introduce commercial products with the new connector. The full IEEE 1394b specification supports data rates up to 3200 Mbit/s (i.e., 400 MB/s) over beta-mode or optical connections up to in length. Standard Category 5e unshielded twisted pair supports at S100. The original 1394 and 1394a standards used data/strobe (D/S) encoding (renamed to alpha mode) with the cables, while 1394b added a data encoding scheme called 8B10B referred to as beta mode. Beta mode is based on 8B/10B (from Gigabit Ethernet, also used for many other protocols). 8B/10B encoding involves expanding an 8-bit data word into 10 bits, with the extra bits after the 5th and 8th data bits.

Built by the Dresser-Ideco Company for the U.S. Atomic Energy Commission, it was first erected in 1962 in the atomic bomb test area at Yucca Flat, where it was used for an experiment intended to improve understanding the effects of radiation in the atomic bombing of Hiroshima. A bare (unshielded) nuclear reactor on a hoist car could be moved to different heights on the tower; Japanese-type houses were built near the base of the tower and were bombarded with various intensities of radiation. After the Nuclear Test Ban Treaty banned open-air nuclear testing, the tower was dismantled and despite its immense size moved from its original location to Jackass Flats in Area 25 of the Nevada Test Site, where it was used for Operation HENRE (High Energy Neutron Reactions Experiment), a series of radiation measurement experiments using a small linear accelerator to provide neutrons.

Apple Music's editorial comments on the overall tone of Sect and notes its Ed Banger influences: "Themes of disorientation and intoxication are unshielded: 'Medicate, separate' and 'I'm high, all day, all night, always', for instance, are repeated as hypnotic mantras over thumping beats, like the soundtrack of a sweaty, strobe-light rave that picks up where Ed Banger Records' mid-2000s heyday left off." The Golden Features project has a "quality over quantity element" which has culminated with Sect, according to Pilerats editor, which is "drenched in care and attention to detail". Chris Salce of Acid Stag praises the production of Sect as a body of work — "a truly remarkable meeting of dark and deep house worlds that solidifies the signature sound we've all come to know". He continues, "Always" "showcases the trademark heavy electronica of Golden Features" and "Falling Out" is a "clear standout" with "contagious melodies".

Played by Paul Putner, Harry Hayes is the fourth member of KENT, responsible for technological development. Though previously a handsome physically spectacular specimen of a man, he was badly injured when Professor Nebulous disintegrated the Isle of Wight, having entered the unshielded control room to try and reverse the process and being badly injured in the resulting blast. He was rebuilt by the Professor and lives his life in constant agony while trundling around in a wheelchair constructed from old kitchen units, though in recent episodes the Professor has given him a new hover chair with slat grates that allow him access to everywhere he could want to go (Which just annoys Harry more as he has less to moan about now). Harry often ends up reminding everyone that while most members of KENT have minor problems, he suffers more than anyone, such as commenting that Paula was just suffering from "some minor agony".

AC-130U sensor suite During the Vietnam War era, the various AC-130 versions following the Pave Pronto modifications were equipped with a magnetic anomaly detector system called Black Crow (designated AN/ASD-5), a highly sensitive passive device with a phased-array antenna located in the left-front nose radome that could pick up localized deviations in the Earth's magnetic field normally used to detect submerged submarines. The Black Crow system was slaved into the targeting computers of the AC-130A/E/H, enabling the detection of the unshielded ignition coils of North Vietnamese trucks hidden under dense jungle foliage along the Ho Chi Minh Trail. It could also detect hand-held transmitter signals of air controllers on the ground to identify and locate targets. The PGM-38/U enhanced 25 mm high-explosive incendiary round was created to expand the AC-130U gunships' mission in standoff range and survivability for its 25 mm GAU-12/U gun.

This mechanic allows players to anonymously place "bounty" on other players, with the goal of inducing the pirates to attack that player. The more bounty is placed on another player, then the larger the attacking fleet will be if the pirates choose to attack that player; pirate raids also gain strength over time, and to deal with them, the player has to find all the pirate bases, which are the spawn points for raids in their respective star system, and wipe them out. Pirate forces are, with one exception, TEC frigates, cruisers, orbital defense platforms, and mines (and the only exception still bears a similarity to Trader ships), but they are all unshielded, have heavier armor, often have their armament switched to autocannons, and are heavily customised with spikes and stylized holographic "Jolly Rogers". Rebellion also has voiced responses for pirate units (which can often found in the service of TEC Rebels).

This modem functionality is integrated into the DSLAM itself instead of being done via an external device like a 20th-century voiceband modem. Like traditional voice-band modems, a DSLAM's integrated DSL modems are usually able to probe the line and to adjust themselves to electronically or digitally compensate for forward echoes and other bandwidth-limiting factors in order to move data at the maximum possible connection rate. This compensation capability also takes advantage of the better performance of "balanced line" DSL connections, providing capabilities for LAN segments longer than physically similar unshielded twisted pair (UTP) Ethernet connections, since the balanced line type is generally required for its hardware to function correctly. This is due to the nominal line impedance (measured in Ohms but comprising both resistance and inductance) of balanced lines being somewhat lower than that of UTP, thus supporting 'weaker' signals (however the solid-state electronics required to construct such digital interfaces are more costly).
