  • Publication number: 20240405696
    Abstract: A vehicle on-board power conversion device includes an inverter configured to convert power output from a power supply of a vehicle and processing circuitry configured to control the inverter. The inverter includes a first inverter circuit configured to convert power, output from the power supply, into single-phase two-wire alternating-current power and supply the single-phase two-wire alternating-current power to the one or more interior power supply ports, and a second inverter circuit configured to convert power, output from the power supply, into single-phase two-wire alternating-current power and supply the single-phase two-wire alternating-current power to the one or more exterior power supply ports. The processing circuitry is configured to determine whether the vehicle is traveling, and, when determining that the vehicle is traveling, stop or limit supply of power to at least one exterior power supply port of the one or more exterior power supply ports.

  • Publication number: 20240405697
    Abstract: A power conversion device includes an inverter, a state detector, a distribution board configured to distribute power output from the inverter such that single-phase three-wire alternating-current power is supplied to a first power supply port and single-phase two-wire alternating-current power is supplied to a second power supply port and a third power supply port, and processing circuitry configured to control the inverter and the distribution board. The processing circuitry is configured to determine whether there is an anomaly in one of a first inverter circuit and a second inverter circuit based on a detection result of the state detector, and when determining that there is an anomaly in one of the first inverter circuit and the second inverter circuit, stop the inverter circuit determined to have the anomaly and switch the first switch of the distribution board to an open state.

  • Publication number: 20220105122
    Abstract: A novel agent is for treating or preventing a glioma. A marker for malignancy of a brain tumor and a prognostic marker for a brain tumor can be used in a method for determining malignancy of a brain tumor and a method for determining a prognosis for a brain tumor patient. The agent for treating or preventing a glioma can include an HVEM inhibitor as an active ingredient. The marker for malignancy of a brain tumor and the prognostic marker for a brain tumor can each include an HVEM protein or an HVEM gene. The method for determining malignancy of a brain tumor and the method for determining a prognosis for a brain tumor patient can each include measuring an HVEM expression amount in a biological sample of a subject.
