A galvanostat (also known as amperostat) is a control and measuring device capable of keeping the current through an electrolytic cell in coulometric titrations constant, disregarding changes in the load itself. Its main feature is its nearly "infinite" (i.e. extremely high in respect to common loads) internal resistance.
In professionally built wire-wrap boards, long wires are placed first so that shorter wires mechanically secure the long wires. Also, to make an assembly more repairable, wires are applied in layers. The ends of each wire are always at the same height on the post, so that at most three wires need to be replaced to replace a wire.
Analog delay lines are applied in many types of signal processing circuits; for example the PAL television standard uses an analog delay line to store an entire video scanline. Acoustic and electromechanical delay lines are used to provide a " reverberation " effect in musical instrument amplifiers, or to simulate an echo.
The transmitter constantly transmits either 32-bit data words or the NULL state (0 Volts). A single wire pair is limited to one transmitter and no more than 20 receivers. The protocol allows for self-clocking at the receiver end, thus eliminating the need to transmit clocking data. ARINC 429 is an alternative to MIL-STD-1553.

Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
Trolley pole wheel on top of the trolley pole of Twin City Rapid Transit Company No. 1300. A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles.
Galloping conductors in eastern Idaho around Christmastime 1998. Conductor gallop is the high-amplitude, low-frequency oscillation of overhead power lines due to wind. [1] The movement of the wires occurs most commonly in the vertical plane, although horizontal or rotational motion is also possible.
