Abstract
A remotely controlled electrical power circuit (10) for supplying power to an electrical load (13) requiring electrical power from an electrical outlet comprising a receiver (14) for receiving a predetermined radio signal from a transmitter (12). The receiver (14) includes a super-generative detector (16) for receiving the predetermined radio signal. An amplifier filter (20) amplifies and filters the signal from the detector (16). A Schmitt trigger (34) detects the signal from the amplifier filter (20) and produces positive feedback to operate a latch (36), causing a detector (38) to produce a control signal in response to a first duration of the predetermined radio signal to operate relay (RY1) for closing contacts (24) and to produce a control signal in response to a second duration of the predetermined radio signal for opening the contacts (24).
