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.

electromechanical device
A mechanical instrument which is operated by electricity.
electromechanical dialer
1. A device on a telephone that activates a group of precoded numbers when a user presses a designated button.
2. A telephone dialer that activates one of a set of desired numbers, coded into it in advance, when the user selects and presses a start button.
electromechanical energy
Energy which is present in an induction coil or solenoid.
electromechanical frequency meter
A meter that uses the resonant properties of mechanical devices to indicate frequency.
electromechanical plotter, digital plotter, plotter, incremental plotter
1. Specifically, an output device that produces graphic or pictorial representations of computer data on a hard copy by drawing with one or more automatically controlled pens that move in small steps as used with digital computers.
2. An automatic device used in conjunction with a digital computer to produce a graphic or pictorial representation of computer data on a hard copy.
3. A graphics printer that draws images with ink pens.

It draws point-to-point lines directly from vector graphics files.

The plotter was the first computer output device that could print graphics as well as accommodate full-size engineering and architectural drawings.

electromechanical recorder
A device that transforms electrical signals into equivalent mechanical motion which is transferred to a medium by cutting, embossing, or writing.
electromechanical recording
1. A document created by varying the signal of electric current flowing through a stylus moving across a sheet of paper.
2. Recording by means of a signal-actuated mechanical device; such as, a pen arm or mirror attached to the moving coil of a galvanometer.
3. A tool that transforms electrical signals into equivalent mechanical motion which is transferred to a medium by cutting, embossing, or writing.
electromechanical relay
1. A device consisting of a coil and an armature that moves under the influence of a magnetic field produced by the coil to close or to open a contacting switch.
2. A protective relay operating on the principle of electromagnetic attraction; such as, a plunger relay or of electromagnetic induction.
electromechanical timer
Usually refers to a motor-driven timer, with or without an electrically operated clutch.

It can also apply to pneumatic and thermal timers, or to slow pull-in or drop-out relays.

electromechanical transducer (s) (noun), electromechanical transducers (pl)
1. An instrument that converts mechanical energy into electrical energy or a reverse process.
2. A transducer (electrical device that converts one form of energy into another) for receiving waves from an electric system and delivering waves to a mechanical system, or the reverse.
electromechanical transduction (s) (noun), electromechanical transductions (pl)
A variation of electromagnetic transduction.

In electromagnetic devices, it is often difficult to control the spatial relationship of the magnet and coil.

Because the magnet is attached to one portion of the anatomy and the coil attached to another part, the patient may observe a wide variation in performance.

As the relationship between the coil and the magnet changes, it results in a variance of the frequency response and a significant fluctuation of output levels.

An electromechanical device has an energizing coil and a magnet that are housed within an assembly which optimizes spatial and geometric relationships in order to avoid variability.

The electromechanical transducer directly connects to the ossicular chain (any of certain small bones, as those of the middle ear) to transmit the mechanical energy that is produced.

1. The science and technology of electromechanical devices, systems, or processes.
2. The technology of mechanical devices, systems, or processes which are electrostatically or electromagnetically actuated or controlled.
3. The branch of electrical engineering concerned with machines producing or operated by electric currents.
1. Relating to electrically operated diagnostic and other medical equipment.
2. A reference to an electrical activity in the body; for example, that of the heart or brain.
Electrical currents used to enhance tissue absorption of medication.
1. A reference to the use of electric and electrolytic processes to purify metals or to reduce metallic compounds to metals. 2. Involving the use of electric-arc furnaces, electrolysis, and other electrical operations.
3. Referring to the science of the electrical processes or methods used industrially for separating metals from alloys, or for the refining or the shaping of metals.
