  • Energizing and measuring the temperature of stator windings in an at least motor-driven electric polyphase machine
    Patent number: 10254174
    Abstract: A method for energizing the stator windings of a rotating field machine operable in motor mode, the stator windings respectively being impinged upon with phase currents that are predefined using a vector-based method. The phase currents are impinged upon at least in part with bias currents that are determined by the vector-based method in such a way that they exhibit no torque effectiveness in the rotating field machine.
    Type: Grant

  • Device and method for optically recording the underbody of a vehicle
    Patent number: 9649990
    Abstract: A device for optically recording the underbody of a vehicle using at least one camera, includes at least two mirrors which are disposed and oriented in such a way that images of several areas of the underbody of the vehicle are able to be recorded simultaneously by the camera.
