electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
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.
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).
2. An electronic component which converts electric signals into visual imagery in real time that is suitable for direct interpretations by a human operator.
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.
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.
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 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.
2. With motion pictures, the editing of film assisted by a duplicate of the action on videotape.
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.
2. A spectrum resulting from the emission of electromagnetic radiation by ions, atoms, and molecules following excitations of their electrons.
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.
2. A precision control of engine-spark timing and exhaust gas recirculation for emissions control and fuel efficiency.
