-tron, -tronic, -tronics +
(Greek: a suffix referring to a device, tool, or instrument; more generally, used in the names of any kind of chamber or apparatus used in experiments)
A possible allusion to the Greek instrumental suffix, as in árotron, "plow" as spelled in the U.S. or "plough", as spelled by the British; from the Greek stem aroun, "to plow".
The suffix -tron is the result of the combining form extracted from electron, used with nouns or combining forms, principally in the names of electron tubes (ignitron; klystron; magnetron) and of devices for accelerating subatomic particles (cosmotron; cyclotron); also, more generally, in the names of any kind of chamber or apparatus used in experiments (biotron).
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.
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. Engineering which deals with the practical applications of electronics including the design, fabrication, and operation of circuits, electronic devices, and systems.
2. An instrument that allows the observation of the fetal heart rates and the maternal uterine contractions which may be applied externally or internally.
With an external monitor, the fetal heart is detected by an ultrasound transducer positioned on the abdomen.
Internal monitoring of the fetal heart rate is accomplished by way of an electrode clipped to the fetal scalp.
2. The electrode used in a burner system that detects the main burner flame and interrupts fuel flow if the flame is not indicated.
A single bond is equivalent to one pair of electrons shared by two atoms.
2. A fuse; such as, the radio proximity fuse, set off by an electronic device incorporated within it.
A fuse that detonates a warhead when the target is within some specified region near the fuse.
Radio, radar, photoelectric, or other devices may be used as activating elements.
2. Heating with radio-frequency current that is produced by an electron-tube oscillator or an equivalent radio-frequency power source.
3. A method of heating a material by inducing a high-frequency current into it or having the material act as the dielectric (having little or no ability to conduct electricity) between two plates charged with a high-frequency current.
2. An instrument which may display bearing and distance to a navigation aid, magnetic heading, track/course and track/course deviation.
3. An electronically generated display that provides a basic horizontal view of the aircraft's navigation picture.
4. A combination instrument which shows a pilot the actual coarse, as compared to the intended coarse, and the relationship of the aircraft to the glide slope.
2. A humidistat (instrument for measuring humidity) in which a change in the relative humidity causes a change in the electrical resistance between two sets of alternate metal conductors mounted on a small flat plate with plastic coating, and this change in resistance is measured by a relay amplifier.
2. Using computers and/or specialized hardware/software to capture (copy), store, process, manipulate, and distribute "flat information" including documents, photographs, paintings, drawings, and plans, through digitization.
3. A photographic system in which a sensor is placed behind a camera lens to convert an image into an electronic signal, that can be stored for later playback on a television screen.
