auto-, aut-

(Greek: self, same, spontaneous; directed from within)

An image recorded on a photographic film or plate produced by the radiation emitted from a specimen; such as, a section of tissue, that has been treated or injected with a radioactively labeled isotope or which has absorbed or ingested such an isotope.
1. Partly automatic; an operation that is partly automatic and partly manual.
2. A reference to a firearm (rifle, pistol, etc.), automatically ejecting the cartridge case (spent shell) of a fired shot and loading the next cartridge from the magazine but requiring a squeeze of the trigger to fire each individual shot.
1. Partially self-governing; especially, with reference to internal affairs.
2. Having the powers of self-government within a larger organization or structure.
3. Ruled partly by its own citizens or rulers and partly by another country or region.
1. The quality or state of being semiautonomous.
2. A semiautonomous system of government.
stochastic automaton, probabilistic automaton
A device, with a finite number of internal states, that scans words over a finite alphabet, with the next state determined according to probabilistic functions of the current input word.
Telautograph, Tel Autograph (s) (noun); Telautographs, Tel Autographs (pl)
A facsimile telegraph for reproducing writing, pictures, maps, etc.

In the transmitter the motions of the pencil are communicated by levers to two rotary shafts, by which variations in current are produced in two separate circuits.

In the receiver these variations are utilized by electromagnetic devices and levers to move a pen as the pencil moves.

telautography, telautograph, telautographic
The transmission of writing or drawing such that the movements of the receiving pen copy those of the transmitting pen or pencil, yielding a facsimile reproduction at the receiving end. Also: telechirography.
voltage regulator, voltage corrector, automatic voltage regulator, voltage stabilizer
1. A circuit or device that produces a nearly constant voltage output, even when the voltage input (line) and current output (load) may vary considerably.
2. A device that maintains the terminal voltage of a generator or other voltage source within required limits despite variations in input voltage or load.
3. A circuit that includes a sensor capable of monitoring the load and restoring the output voltage to close tolerance limits despite changes in both the load and the input voltage.
4. Any electrical or electronic device that maintains the voltage of a power source within acceptable limits.

The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.

Voltage regulators also are used in electronic equipment in which excessive variations in voltage would be detrimental.
