Abstract
A transmitter is preprogrammed to transmit a digital binary bit time sequence code of a selected number of bits each occupying approximately 12 milliseconds of time. A receiver decodes the transmitted bit code within a fifth of a second to cause actuation of the switch, all within a one second lockout to prevent receipt of an additional code by an intruder or unauthorized user.
