ABSTRACT:
A locking mechanism for use in a door and the like. A remote handheld controller transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts solely along or about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handle in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.
