Abstract
Abstract The system provides electricity to operate any of a multiplicity of device and most typically receives power from a source and passes power to any of the devices. The system also accepts electronic-device identification information for any particular one of such devices. The system also has one or more programmed digital electronic microprocessors that use the identification information to select power parameters--for passage of power from the source to the powered device. The system activates its own power-passing capability to apply power to each device according to the power parameters selected by the microprocessor. A cable, which for some purposes may regarded as part of the system and for some purposes is a separate invention, connects the microprocessor and power-passing parts of the system to the powered device; the identification information is held either in the cable--typically in a ROM, PROM, EPROM or other memory chip in one of the end connectors of the cable--or in the device to be powered, and is read by the system microprocessor before power is supplied.
