  • Torque transmission device
    Patent number: 8739654
    Abstract: A torque transmitting unit for inclusion in the drive train of a motor vehicle. The unit transmits torque between an engine having an output shaft and a transmission having at least one input shaft that is drivingly coupled with the engine by a clutch and a intermediate torsional vibration damper. The torque transmitting unit includes primary and secondary flywheel masses that are mounted on the transmission input shaft along with the clutch.

  • DC to DC converter
    Patent number: 8129963
    Abstract: The invention relates to a DC to DC converter comprising a DC to DC converter unit (DCW), a first field effect transistor (FET1) for the voltage conversion, a bipolar transistor (BP1) as a starting aid, and a second field effect transistor (FET2) for switching-off the bipolar transistor (BP1). Said bipolar transistor (BP1) is mounted in parallel with the first field effect transistor (FET1), and the second field effect transistor (FET2) is mounted upstream of the bipolar transistor (BP1).
