Abstract
The present invention relates to a control system for selectively supplying electrical power in a remote environment. The system comprises a plurality of electrical circuits, each designed to operate over a unique frequency passband. Power transmitted within the frequency passband of a circuit is filtered through that circuit to power a corresponding remote device. One or more remote devices can be simultaneously powered by transmitting power within the frequency passbands of the corresponding circuits. It is advantageous to design relatively narrow passbands to accommodate a relatively large number of circuits and corresponding devices for remote operation and a triac, rectifier or other suitable turn-on gate can be incorporated into each circuit to effectively control the width of the frequency passband of each circuit. Alternatively, an operational amplifier could be used.
