Since the later discovery of the electron, an easier to remember, and more durably correct technically although historically false, etymology has been suggested: anode, from the Greek anodos, ' way up ', ' the way ( up ) out of the cell ( or other device ) for electrons '.

A boomerang is usually thought of as a wooden device cut from a tree trunk, although historically boomerang-like devices have also been made from bones.

Since the later discovery of the electron, an easier to remember, and more durably technically correct ( although historically false ), etymology has been suggested: cathode, from the Greek kathodos, ' way down ', ' the way ( down ) into the cell ( or other device ) for electrons '.

Inefficiency comes not just from the fact that the device is always conducting to some extent ( that happens even with class AB, yet its efficiency can be close to that of class B ); it is that the standing current is roughly half the maximum output current ( although this can be less with square law output stage ), together with the problem that a large part of the power supply voltage is developed across the output device at low signal levels ( as with classes AB and B, but unlike output stages such as class D ).

Class-A amplifiers are often used in output stages of high quality op-amps ( although the accuracy of the bias in low cost op-amps such as the 741 may result in class A or class AB or class B, varying from device to device or with temperature ).

The Intellivoice was original in two respects: not only was this capability unique to the Intellivision system at the time ( although a similar device was available for the Odyssey2 ), but the speech-supporting games written for Intellivoice actually made the speech an integral part of the gameplay.

The coining of the term " joystick " may actually be credited to Loraine, as his is the earliest known usage of the term, although he most certainly did not invent the device.

The device was determined to be a three-foot (. 9-m ) long TOW missile used in the training of federal agents and bomb-sniffing dogs ; although actually inert, it had been marked " live " in order to mislead arms traffickers in a planned law enforcement sting.

The stylus is the primary input device for personal digital assistants and smartphones that require accurate input, although devices featuring multi-touch finger-input with capacitive touchscreens are becoming more popular than stylus-driven devices in the smartphone market.

An expensive measuring device, for no apparent reason, suddenly stopped working, although Pauli was in fact absent.

This stylistic device did not originate in the screwballs ( although it may be argued to have reached its zenith there ): it can also be found in many of the old Hollywood cycles including the gangster film, romantic comedies, and others.

R. Hilsch and R. W. Pohl in 1938 demonstrated a solid-state amplifier using a structure resembling the control grid of a vacuum tube ; although the device displayed power gain, it had a cut-off frequency of one cycle per second, too low for any practical applications, but an effective application of the available theory.

Both of these books are composed of individual short stories ( which range from farce or humorous anecdotes to well-crafted literary fictions ) set within a larger narrative story ( a frame story ), although the frame-tale device was not adopted by all writers.

The first diving equipment that combined a high-pressure cylinder and a breathing device ( although not a demand regulator as was the Rouquayrol-Denayrouze apparatus ) was invented separately by the Japanese Ohgushi in 1918 and the Frenchmen Maurice Fernez and Yves le Prieur in 1926.

A prominent feature about it was a device designed by Sinister that negated the powers of any mutant in the Savage Land save for Sinister's own forces, rendering the X-Men powerless while fighting him ( With the exception of Wolverine's claws as they were a ' bonus ' of the Weapon X process, although they would thus cause damage to his hands when used ) until the machinery was destroyed.

They also popularized the word " transformer " to describe a device for altering the EMF of an electric current, although the term had already been in use by 1882.

The well-known aphorism, " A mathematician is a device for turning coffee into theorems ", is probably due to Alfréd Rényi, although it is often attributed to Rényi's colleague Paul Erdős ( and Rényi may have been thinking of Erdős ), who was famous for the many theorems he produced, the number of his collaborations, and his coffee drinking.

Multiple classifications may apply to a device ; for example similar dual triodes can be used for audio preamplification and as flip-flops in computers, although linearity is important in the former case and long life in the latter.

A project for the Air Force has been completed in which the NAIR infrared detecting device was developed for area monitoring of noxious or dangerous gases.

The deep concave gradient employed ( fig. 2 ) was obtained with a nine-chambered gradient elution device ( `` Varigrad '', reference ( 8 ) ) and has been described elsewhere.

`` Unfortunately '', says Chief Postal Inspector David H. Stephens, who has prosecuted many device quacks, `` the ghouls who trade on the hopes of the desperately ill often cannot be successfully prosecuted because the patients who are the chief witnesses die before the case is called up in court ''.

The name of the device has since been borrowed by authors such as Orson Scott Card,

Additionally, Elihu's first spoken words are a confession of his youthful status, being much younger than the three canonical friends, including a claim to be speaking because he cannot bear to remain silent ; it has been suggested that this interesting statement may have been symbolic of a " younger " ( that is to say, later and interpolating ) writer, who has written Elihu's sermon to respond to what he views as morally and theologically scandalous statements being made within the book of Job, and creating the literary device of Elihu to provide what seemed to be a faith-based response to further refute heresy and provide a counter-argument, a need partially provided by God's ambiguous and unspecific response to Job at the end of the book.

Once one copy of a document has been produced, printing further copies is often quicker by means of a device called a " thermoform ", which produces copies on soft plastic.

Once a prototype has passed the tests at a certification lab, and that model is being constructed under the control of a certified quality system, the device is entitled to bear a CE mark, indicating that the device is believed to be safe and reliable when used as directed.

Research in condensed matter physics has given rise to several device applications, such as the development of the semiconductor transistor, and laser technology.

The BAT is a 7-key hand-sized device from Infogrip, and has been sold since 1985.

The Mini CD has various diameters ranging from ; they are sometimes used for CD singles, storing up to 24 minutes of audio or delivering device drivers.

The causeways themselves may have been slightly submerged ; this has been interpreted as a device to make access difficult yet this can also simply be a by-product of loch level fluctuations over the ensuing centuries or indeed millennia.

A transformer is an electromagnetic device that has a primary winding and a secondary winding that transfers energy from one electrical circuit to another by inductive coupling without moving parts.

As a dramatic plot device, Clark often has to quickly improvise in order to find a way to change unnoticed.

In digital logic and computing, a counter is a device which stores ( and sometimes displays ) the number of times a particular event or process has occurred, often in relationship to a clock signal.

As a member of the Avengers, Rogers has an Avengers priority card, which serves as a communications device.

When a new symbol has been entered, the device typically sends an interrupt to alert the CPU to read it.

Microsoft has attempted to reduce system instability due to poorly written device drivers by creating a new framework for driver development, called Windows Driver Foundation ( WDF ).

A PCI device has often an ID pair for the main chip of the device, and also a subsystem ID pair which identifies the vendor, which may be different from the chip manufacturer.

The Curse of Davros begins with Davros and the Daleks working together to try and alter the outcome of the Battle of Waterloo using technology that Davros has created that allows him to swap peoples ' minds, with matters becoming more complicated when the Sixth Doctor uses the device to swap bodies with Davros in an attempt to subvert the Daleks ' plans from the inside.
