  • Load shedding circuit for RAM air turbines
    Patent number: 9083201
    Abstract: A power generation/distribution system includes a RAM air turbine (RAT) generator and an emergency integrated control center (EICC) that selectively applies either primary power provided by a primary power source or emergency power developed by the RAT generator to an alternating current essential bus (AC ESS bus) for distribution to one or more essential loads. The EICC monitors the primary power and in response to a loss of primary power selectively disables the supply of power from the AC ESS bus to the essential loads and manages subsequent loading of the RAT generator by the essential loads.
    Type: Grant

  • Architecture using integrated backup control and protection hardware
    Patent number: 8340793
    Abstract: An electronic control configuration includes at least one secondary microprocessor operable to control a device. The at least one secondary microprocessor assumes protection control of the device responsive to a first type of failure by transmitting a protection control signal to a first effector. The at least one secondary microprocessor assumes backup control of the device responsive to a second type of failure by transmitting a backup control signal to a second effector. The backup control functionality of the at least one secondary microprocessor can be selectively disabled.
