  • Keyhole-less electronic lock
    Patent number: 4031434
    Abstract: An inductively coupled electronic lock system wherein a key unit receives binary multiple bit data and generates a binary frequency modulated carrier which is input to a transmitter inductor. A lock unit of the system has an inductive pick-up which compares the received sequence of binary signals with a predetermined sequence of binary signals so that upon a proper correspondence a motor opens the lock.
