For large power units, dynamic uninterruptible power supplies (DUPS) are sometimes used. A synchronous motor/alternator is connected on the mains via a choke. Energy is stored in a flywheel. When the mains power fails, an eddy-current regulation maintains the power on the load as long as the flywheel's energy is not exhausted.
The technology of force-sensing resistors was invented and patented in 1977 by Franklin Eventoff. In 1985 Eventoff founded Interlink Electronics, [2] a company based on his force-sensing-resistor (FSR). In 1987, Eventoff received the prestigious International IR 100 award for developing the FSR.
The first use of Army branch insignia was just prior to the American Civil War in 1859 for use on the black felt hat. A system of branch colors, indicated by piping on uniforms of foot soldiers and lace for mounted troops, was first authorized in the 1851 uniform regulations, with Prussian blue denoting infantry, scarlet for artillery, orange for dragoons, green for mounted rifles, and black ...
Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs includes important analog design considerations.
In electronics or electrical engineering the form factor of an alternating current waveform (signal) is the ratio of the RMS (root mean square) value to the average value (mathematical mean of absolute values of all points on the waveform). [1] It identifies the ratio of the direct current of equal power relative to the given alternating ...
RS-259, 75Ω RF high power RF connectors, (EIA RF Connectors) EIA-274 is the most common NC code format. In the machine tool industry it also known as G-code. In the PCB industry Standard Gerber, now revoked, was based on it. RS-279 electronic color code originally known as the RETMA color code
The term is used more broadly in electronics for a device connected to a signal source, whether or not it consumes power. [2] If an electric circuit has an output port , a pair of terminals that produces an electrical signal, the circuit connected to this terminal (or its input impedance ) is the load .
