  • Patent number: 10229802
    Abstract: A circuit arrangement is described herein. In accordance with one exemplary embodiment, the circuit arrangement includes at least one output channel configured to be operably coupled to at least one load that is to be driven by the circuit arrangement. In the at least one output channel, the circuit arrangement includes a driver circuit configured to provide a modulated output signal, a current sense circuit configured to sense a load current passing through the load, and a feedback circuit configured to receive the modulated output signal and to determine, based on the modulated output signal, at least one digital value representing an average of the load current.
    Type: Grant

  • Patent number: 10174837
    Abstract: An automatic transmission for a vehicle drivetrain includes a transmission housing, an input shaft, an output shaft, and a plurality of gears within the transmission housing. The plurality of gears defines multiple mechanical gear ratios between the input shaft and the output shaft. The transmission further includes a plurality of clutches operable to selectively engage the multiple mechanical gear ratios, and a plurality of rotational speed sensors. Each rotational speed sensor is operable to measure rotational speeds relative to the transmission housing for of one of the input shaft, the output shaft, or one of the plurality of gears. The transmission further includes a transmission control system configured to receive signals representing the measured rotational speeds from the plurality of rotational speed sensors and control the plurality of clutches to change between gear ratios based at least in part on the signals representing the measured rotational speeds.
