ABSTRACT:
An electronic combination lock includes a combination lock having a dial with no markings thereon. Rotation of the dial drives a generator which produces electrical pulses. The voltage pulses serves as a power source for the electronics of the lock. The lock also includes a security feature to disable the lock if the combination dial is stopped between dial rotations for a period of time which indicates dialing by an automatic dialer.
