The capacitor forms a time constant with the resistor load, which determines the range of frequencies over which the clamper will be effective.

By using a voltage source and resistor, the clamper can be biased to bind the output voltage to a different value. The voltage supplied to the potentiometer will be equal to the offset from zero (assuming an ideal diode) in the case of either a positive or negative clamper (the clamper type will determine the direction of the offset). If a negative voltage is supplied to either positive or negative, the waveform will cross the x-axis and be bound to a value of this magnitude on the opposite side. Zener diodes can also be used in place of a voltage source and potentiometer, hence setting the offset at the Zener voltage.

Other motorists have cut the clamps off with bolt cutters or even clamping their own cars beforehand so that property owners will be unable to clamp an already-clamped vehicle and may think that another owner has clamped it. However, the practice of removing clamps is usually only done for those that were installed by firms and other citizens; the removal of clamps installed by authorities (chiefly the police) is an offence. A New Zealand wheel clamper made national headlines in 2013 after he secretly recorded a police officer allegedly threatening to not help if an aggrieved member of the public attacked him. It was not the first time the clamper involved had been in the news.

In honor of Sarah, John, and Beatrice Kidder, the Ancient and Honorable Order of E Clampus Vitus planted three trees in Grass Valley's Clamper Square. Two other plaques mentioning Kidder have also been placed at either end of the railroad. The Nevada County Narrow Gauge Railroad Museum's railbus is named after Kidder.

V. L. Vander Hoof, a fellow Clamper and Berkeley professor, made a spoof of the plate a few weeks after the announcement of the find, hoping to show Bolton that modern tools could make a plate that looked remarkably like the "real" plate. Clamper Edwin Grabhorn, a Western history publisher, published a spoof letter from the "Consolidated Brasse and Novelty Company" offering a "special line of brass plates" guaranteed to "make your home-town famous." Finally, ECV produced a small press run of a book, Ye Preposterous Booke of Brasse, detailing problems with the metal content, wording and spelling. The book even instructed the reader to look for the "ECV" in fluorescent paint on the back and stated outright "we should now re-claim [the plate] as the rightful property of our ancient Order", meaning ECV.

Positive unbiased voltage clamping vertically translates the input waveform so that all parts of it are approximately greater than 0 V. Note that the negative swing of the output will not dip below about −0.6 V, assuming a silicon pn diode. A clamper is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined value by shifting its DC value. The clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as to place the peaks at the reference level. A diode clamp (a simple, common type) consists of a diode, which conducts electric current in only one direction and prevents the signal exceeding the reference value; and a capacitor, which provides a DC offset from the stored charge.

A clamping circuit (also known as a clamper) will bind the upper or lower extreme of a waveform to a fixed DC voltage level. These circuits are also known as DC voltage restorers. Clampers can be constructed in both positive and negative polarities. When unbiased, clamping circuits will fix the voltage lower limit (or upper limit, in the case of negative clampers) to 0 volts.

Haworth is served by Keighley Bus Company rural bus service which provides links to the main local town of Keighley and the local villages of Oxenhope, Stanbury, Oakworth and Denholme. There is also a service to Hebden Bridge. Evening and Sunday services are partly paid for by Metro. Central North Street Car Park Haworth, formerly Changegate Car Park, has been subject of a Channel 4 television documentary "The Yorkshire Clamper", regarding their tactics.

The Clamper flag was a hoop skirt, with the words "This is the flag we fight under." Meetings were held "at any time before or after a full moon." New members were called "Poor Blind Candidates." They were required to present a poke of gold dust, although the value of the poke was left to the discretion of the brotherhood, and was frequently waived entirely if the prospective member could not afford it.

When a local Clamper found out that the troupe was having trouble, Lord Douglas was immediately initiated into ECV, and the brothers bought enough tickets to fill the local theater. A 20th century chapter of the ECV was named for Lord Douglas in honor of this event. Mark Twain was a member, and it was while attending an ECV meeting that he heard the story which he wrote as The Celebrated Jumping Frog of Calaveras County.

During the first negative phase of the AC input voltage, the capacitor in a positive clamper circuit charges rapidly. As Vin becomes positive, the capacitor serves as a voltage doubler; since it has stored the equivalent of Vin during the negative cycle, it provides nearly that voltage during the positive cycle. This essentially doubles the voltage seen by the load. As Vin becomes negative, the capacitor acts as a battery of the same voltage of Vin.

According to this account, the plate was intended to be a joke among members of a playful fraternity of California history enthusiasts, the Ancient and Honorable Order of E Clampus Vitus ("ECV"). George Ezra Dane, an ECV leader, initiated the hoax as a joke intended for fellow "Clamper" Herbert Bolton to find. The plate was likely made by George Clark in his workshop. Wheat was the leading figure in reviving ECV as a fraternity of historians and Western lore enthusiasts.

The joke, originally intended as an internal Clamper affair, had quickly and suddenly broken out into the public eye. Rather than unveiling their prank at an ECV dinner among friends, revealing the hoax would now be a very public and painful proposition for all involved. As Von der Porten and others wrote, "Private confession could not be kept private, and public confession was fraught with great peril." The conspirators found a number of ways of trying to tip off Bolton without coming forward.

This simple diode clamp will clamp the negative peaks of the incoming waveform to the common rail voltage A diode clamp circuit can take a periodic alternating current signal that oscillates between positive and negative values, and vertically displace it such that either the positive or the negative peaks occur at a prescribed level. The clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as to place the peaks at the reference level.

ABC decided that in order to save money, there would be no satellite uplink trunk present at San Francisco's Candlestick Park. Instead, the feed from San Francisco back to ABC's headquarters in New York would take a complex, circuitous route. For starters, the signal would go from the truck to a telephone company room (dubbed a "clamper room") at the third level of the stadium. From there, the signal would be transmitted over a fiber optic cable onto the local phone company switching office.

A clampout at sunset. Clampsite location is China Harbor on the Pacific Coast near Cayucos, California. A plaque placed by E Clampus Vitus in San Francisco, California. Plaque commemorating the Star of India as a California landmark Plaque marking the original location of the 21st Catholic mission in Sonoma, California In 1991 there were 50,000 Clampers in 62 lodges. There are currently 46 ECV chapters in California, Oregon, Washington, Idaho, Nevada, Utah, Arizona/New Mexico, Montana and Colorado, as well as an offshore chapter (the Floating Whang chapter), an online chapter (the Cyber Whang chapter), and two more proposed chapters. Al Packer Chapter 100 in Colorado was chartered in 2000—the year 6005 on ECV's idiosyncratic calendar. This chapter has split into two Colorado chapters, Al Packer Chapter #100 East of the Continental Divide and Robert Leroy Parker Chapter #1889 West of the Continental Divide. Doc Maynard Chapter #54-40 in Washington State was chartered in 2006, the year 6011 in Clamper years, signifying the first Chapter in the Pacific Northwest. Snake River Chapter #1811 (Idaho) and Umpqua Joe Chapter #1859 (Oregon) are the most recently chartered Chapters in States that did not previously have an official Chapter, in May 2010, the year 6015 in Clamper years.

The organization has raised historical plaques in many places throughout the West (often at sites such as bordellos and saloons overlooked by more traditional historical societies), with a traditional "doin's," or party, after each plaque dedication. These are now common in historical areas around California and the West—when in the Gold Country, a Clamper-placed plaque is never far away. In 1999, a plaque was placed on the Star of India, the oldest iron-hulled merchant ship afloat, by the State Department of Parks and Recreation in cooperation with the Ancient and Honorable Order of E Clampus Vitus John P. Squibob Chapter 1853.

In summary, the decision established that applying a wheel clamp to a vehicle constitutes a trespass to goodsStreet on Torts 12th Edition, by John Murphy, Oxford University Press, 2007, p.276, 296 and that the onus remains with the clamper to demonstrate that the person parking the vehicle knew of the risks and happily took these on at the time that he parked the vehicle. Although it might reasonably be inferred that a motorist saw and understood the signs as a result of their numbers, size and location it was insufficient that an appellant had simply had the opportunity to see warning signs but that they must also have read and understood them and only then, by doing so, could they consent to the act of clamping if they parked in contravention to the notices. By extension, it was held, if the fee was exorbitant then consent to its payment could not be implied. Cases referred to: Lloyd v Director of Public Prosecutions [1992] 1 All ER 982 - criminal offences Arthur & Another v Anker & Another [1997] QB 564 Rookes - v - Barnard [1964] AC 1129 - as to damages only.
