electro-, electr-, electri-

A standardized exchange language for design information.

A computer programmed to carry out the work traditionally accomplished at a desk instead of a hand-held device or a laptop.

1. A unit of equipment with circuits containing electron tubes, transistors, integrated circuits, or other devices that perform a function.
2. An instrument in which conduction is principally by the movement of electrons through a vacuum, gas, or semiconductor.
3. An electronic tube or valve, transistor, or other semiconductor tool; excluding inductors, capacitors, resistors and similar components.

An input or output type of circuit which only amplifies or responds to the difference of two signals, and does not respond to the signal with respect to ground or a supply voltage.

A machine that uses electronic circuitry in the main computing element to perform arithmetic and logical operations on digital data; for example, data represented by numbers or alphabetic symbols.

This is done automatically with an internally stored program of machine instructions.

Such instruments are distinguished from calculators on which the sequence of instructions is externally stored and is impressed manually (desk calculators) or from tape or cards (card-programmed calculators).

1. An electronic part which converts electromagnetic signals into a visible display.
2. An electronic component which converts electric signals into visual imagery in real time that is suitable for direct interpretations by a human operator.

A navigation system consisting of airborne devices which transmit microsecond pulses to special ground beacons and that retransmit the signals to an aircraft.

The length of expired time between a transmission and a reception is measured, converted to kilometers or miles, and presented to a pilot of an aircraft.

An electronic instrument for measuring the drift angle or the angle between the longitudinal axis of an aircraft and its path relative to the ground or the angle made by the path of a drifting vessel with its heading.

It may be an attachment to an airborne radar and it is an integral part of a Doppler navigator which refers to the change in electromagnetic frequency that occurs when the source of the radiation and its observer move toward or away from each other.

The faster they come together, the higher the frequency or the faster they move away from each other, the lower the frequency.

1. A device which is used for simulating impedance, frequency response, and other characteristics of the human body to provide approximately equivalent features in vocal and hearing.
2. A vocal simulator that is a replica of the head and torso of a human, covered with plastisol or artificial flesh which is similar to the acoustical and mechanical properties of real flesh, and having an artificial voice and artificial ears.

A electronic instrument that can instantly register the body temperature of a person when it is placed in an ear.

A patient's temperature can be taken while he or she is asleep and the patient will rarely be aware of the procedure because, among other technologies, it provides an active-user feedback light, and guiding proper probe positioning.

One electronic ear thermometer manufacturer claims that this device offers professional accuracy with proven speed, accuracy and ease of use, and it measures temperature in the ear in just one second, and then beeps when it is ready to be read.

A memory function displays the last eight temperatures taken and it also features an easy-to-read LCD-display which indicates the temperature in either Celsius or Fahrenheit, an auto shut-off after two minutes, and a lens filter ejector.

1. In television, the editing of videotape by electronic operations without cutting and splicing the tape.
2. With motion pictures, the editing of film assisted by a duplicate of the action on videotape.

1. A relation in degree or number between the power at a given frequency which is delivered by an electron stream to an oscillator or amplifier to the average power supplied to the electron flow.
2. The ratio of the power at a desired frequency, delivered by an electron flow or stream to the circuit in an oscillator or amplifier circuit and then to the average power supplied to the stream of data from a source.

1. Any spectrum produced by the emission of electromagnetic radiation by atoms, molecules, or ions, because of electron excitation or the signal voltage that is applied to the control electrode of an electron tube.
2. A spectrum resulting from the emission of electromagnetic radiation by ions, atoms, and molecules following excitations of their electrons.

1. A graph that shows the range of energy levels in a diatomic (double atomic) molecule, based on the distance between the nuclei of its two atoms.
2. A graph of the energy of a diatomic (two atoms) molecule in a given electronic state as a function of the distance between the nuclei of the atoms.

1. The engine management system that controls the ignition system and various other systems, including the exhaust gas recirculation and air-injection systems.
2. A precision control of engine-spark timing and exhaust gas recirculation for emissions control and fuel efficiency.
