  • Patent number: 10656115
    Abstract: A controller of an air-fuel-ratio sensor according to an embodiment includes a current supplying unit, a sweep processing unit, and an abnormality detecting unit. The current supplying unit supplies a current to the pump cell through a first terminal connected with the pump cell so as to control the pump cell. The sweep processing unit executes a sweeping process in which a predetermined voltage or a predetermined current is applied to the detection cell through a second terminal connected with the detection cell so as to change a voltage and a current of the detection cell. The abnormality detecting unit detects a short-circuited state between the first terminal and the second terminal on the basis of a fluctuation in a voltage or a current, generated by the sweeping process, of the first terminal.

  • Patent number: 10316780
    Abstract: A controller of an air-fuel-ratio sensor includes a control unit, a voltage-abnormality detecting unit, and a short-circuit-abnormality detecting unit. The control unit controls a current and a voltage of a gas sensor element through a plurality of terminals connected with the gas sensor element. The voltage-abnormality detecting unit changes, when at least one of voltages of the plurality of terminals is out of a predetermined range, a voltage level of an output voltage. The short-circuit-abnormality detecting unit causes, when the voltage level of the output voltage changes from a first voltage into a second voltage, a control unit to perform for a predetermined time a protective operation that suppresses currents from the control unit to the plurality of terminals, and detects, when the voltage level of the output voltage is the second voltage after the protective operation is released, a short-circuit abnormality.

  • Patent number: 10044226
    Abstract: A first oscillator is configured to be switchable between a disabled state and an oscillation state in which a first clock signal CLK1 having a first frequency is generated. A second oscillator oscillates at a second frequency that is lower than the first frequency, so as to generate a second clock signal. In (i) a power transfer phase in which electric power is transmitted to a wireless power receiving apparatus, a controller instructs the first oscillator to oscillate, and generates a first pulse signal for controlling a driver according to the first clock signal. In (ii) a selection phase in which the presence or absence of the wireless power receiving apparatus is detected, the controller generates a second pulse signal for controlling the driver at a predetermined time interval, which is measured based on the second clock signal, and during which the first oscillator is set to the disabled state.
