Abstract:

A system for establishing a code and controlling operation of equipment. This system includes a first transmitter including a random code generator and a memory for storing the randomly generated code, as well as a transmitter for providing a radio frequency signal carrying that code. The system furthermore includes a transceiver including a receiver for the siganl generated by the first transmitter and a memory for storing the code carried by that signal. The transceiver includes a second transmitter for transmitting a radio frequency signal carrying the code. This system also includes a remote receiver unit for connection to the equipment to be controlled. This remote receiver unit has a receiver for the radio frequency signal transmitted by either the first transmitter or the transceiver and a memory for storing that random code carried by the signal. The remote receiver also includes a comparator for comparing a code carried by a radio frequency signal with the code stored in the memory of the remote reciever unit. The remote receiver unit also includes an actuator for causing operation of the equipment if the receiver code matches the stored code.
