  • LOAD SHARING ARCHITECTURE FOR REDUNDANT CHANNEL CONTROLLERS
    Publication number: 20140114494
    Abstract: A redundant, multi-source architecture provides output loads access to each of the plurality of power sources. The architecture includes at a least a first power bus and a second power bus. A plurality of loads are connected to the first power bus and the second power bus. Redundant first and second channel controllers are connected to receive power from the first power bus and the second power bus, respectively, wherein one of the first and second channel controllers is designated as the active channel controller. The active channel controller allocates power from both the first power bus and the second power bus to each of the plurality of loads.

  • Counter electro-motoric force based functional status detection of an electro-motor
    Patent number: 8525452
    Abstract: The present invention relates to a circuit for detecting a functional status of an electro-motor. Typical electro-motors need additional components to identify the functional status of the motor. This means additional weight for such motors determining the functional status. According to the present invention, a circuit is provided using a part of a motor as a sensor for detecting the functional status of the electro-motor.
