  • Patent number: 10707868
    Abstract: A proximity sensor includes a transmission circuit that supplies a current to each of detection coils, a reception circuit that detects voltages generated at both ends of the coils or currents flowing in the coils due to the supply of the current for each of the coils, a control unit that senses the presence or position of a detection object using a detection result of the reception circuit, and an output unit that outputs a sensing result of the control unit. The control unit extracts a first component caused by a mounting fitting for mounting the proximity sensor on a support member and a second component caused by the detection object from the detection result of the reception circuit. The control unit compensates the second component using the first component. The control unit senses the presence or position of the detection object on the basis of the compensated second component.

    Abstract: An alternating current (AC) to direct current (DC) power converter may have a connector with a pair of power supply contacts and a pair of data contacts. An electronic device may be connected to the connector of the power converter. The power converter may supply DC power to the electronic device using the power supply contacts. The power converter may include control circuitry that has a resistor coupled across the data contacts. When the electronic device and the power converter are connected to each other, each may advertise to the other that capabilities are present that exceed industry standards. At the same time, standard-compliant discovery operations may be performed to probe the value of the resistance of the resistor that is coupled across the data contacts. When extended capabilities are discovered, extended functions may be performed including accelerated charging functions and data communications functions.

  • Patent number: 10640003
    Abstract: The methods and systems for correcting for an inductive load when testing high voltages devices are described. A high voltages device is a device under test (DUT) in a double-pulse test, which may require the inductive load. The method can include in a low current, high voltage time period, estimating an inductor current contribution range after a turn on of the device-under-test connected to an inductive load with an air core inductor. The method subtracts the estimated inductor current contribution from a device-under-test collector current to output a corrected collector current. This allows the double pulse test to be conducted with an air-core inductor. Vehicles can use the DUT in traction power applications.
