  • Fault flag driver
    Patent number: 4739326
    Abstract: The present apparatus relates to nonvolatile fault flags for use in aircraft. The term "flag" refers to an electromechanical indicator which displays a human-readable signal which identifies a fault. A fault is a malfunction occurring in the aircraft. The term "nonvolatile" refers to the feature that the signal is not lost when electrical power is terminated to the indicators.

  • Protection circuit
    Patent number: 4481553
    Abstract: An overload protection circuit for an electrical signal source is disclosed in which an overcurrent in the signal source is sensed and the source is disabled for a predetermined time interval. If the overcurrent condition persists beyond the predetermined time interval, the turn-off cycle is repeated. The system is immune to overcurrent transients and the amplitude of the current which triggers turn-off, as well as the length of the predetermined time interval, may be selectively set.
