  • Patent number: 9859702
    Abstract: A method for interrupting a current of an electrical power supply line includes integrating a supply line signal of the electrical power supply line over a predetermined time period to obtain an integrated signal, determining whether the integrated signal meets a predetermined condition, and using a current interrupting element to interrupt the current if the integrated signal meets the predetermined condition.
    Type: Grant

  • Patent number: 9755418
    Abstract: A device and method for fuse protection of a line includes at least two sensors for sensing a corresponding electric variable in a first location and a second location along a conductor line, and for outputting a corresponding first value and second value of the electric variable at the first and second locations, respectively. An evaluation unit evaluates the generated first and second values in order to generate an evaluation result. The evaluation unit controls, based on the evaluation result, an isolating element to cause the isolating element to interrupt a current flow in the conductor line.

  • Publication number: 20150295395
    Abstract: A method for interrupting a current is proposed, wherein a signal of a supply line is integrated over at least one predetermined time period and wherein the current in the supply line is interrupted by means of a separating element if the signal integrated over the at least one predetermined time period meets a predetermined condition.

  • Patent number: 7540213
    Abstract: A gearshift system for a vehicle, such as a motor vehicle includes a gearshift knob in which a plurality of functional and/or control elements are integrated. A gearshift rod is connectable to the gearshift knob. A plurality of functional and/or control elements are connected to an electronic system disposed within the gearshift knob. The electronic system is connectable to an electronic system in the vehicle via a bus that extends along the gearshift rod.
