ABSTRACT:
The present invention provides a system and a method for controlling electrical devices connected to an AC power line by means of control signals transmitted over the AC power line. The control system consists of a transmitter apparatus and a receiver apparatus. The transmitter apparatus generates, and transmits via an AC power line, multiple voltage pulses during any one-half cycle of the AC power line voltage. The multiple voltage pulses act as control signals for any electrical device that is sought to be controlled, or a "slave" device. The receiver apparatus is simultaneously coupled to the slave device and the AC power line for receiving and, if necessary, decoding the voltage pulses sent by the transmitter apparatus. The receiver apparatus in turn generates a command signal that controls the slave device's operation.
