  • Control circuit for selectively providing electrical energy to an electrically controlled lock actuator
    Patent number: 5892298
    Abstract: A circuit which includes a primary power source, a reserve power source, switch means, a first diode, a second diode, and processing means selectively provide power to each of the lock actuator and the processing means from either the primary power source or the reserve power source. The reserve power source is connected between ground and the lock actuator and the switch means is connected between the reserve power source and the lock actuator. The first diode is connected between the reserve power source and the switch means and the second diode is operatively connected between the primary power source and the switch means such that a cathode of the second diode is connected between the first diode and the switch means. The processing means includes a first input operatively connected between the switch means and the lock actuator.
