Abstract: Methods, systems, and apparatus for wirelessly providing power to a vehicle. The system includes a plurality of ground-side wireless power transfer devices each configured to automatically provide power to a counterpart vehicle-side wireless power transfer device. The system includes a switch connecting a power source to the plurality of ground-side wireless power transfer devices and configured to be in an open position or a closed position. The system includes a vehicle position sensor configured to detect the vehicle being within a range of the plurality of ground-side wireless power transfer devices. The system includes a switch driver configured to move the switch from the open position to the closed position when the vehicle position sensor detects the vehicle being within the range, and move the switch from the closed position to the open position when the vehicle position sensor does not detect the vehicle being within the range.

Abstract: A semiconductor module includes an upper arm and a lower arm of an inverter circuit. The upper arm has a switching element and a rectifying device and the lower arm has a switching element and a rectifying device. The upper arm and the lower arm are laminated such that the switching elements overlap each other and the rectifying devices overlap each other. Refrigerant flow paths constituting cooling sections respectively extend along both sides in the lamination direction of the switching elements and the rectifying devices and are folded back at the rectifying device lamination section side.

Abstract: A signal transmitting circuit includes a HDMI signal transmitting unit adapted to output a HDMI signal, a VGA signal transmitting unit adapted to output a VGA signal, a VGA signal processing unit, and a transmitting control unit. The VGA signal processing unit is connected to the VGA signal transmitting unit. The VGA signal processing unit is adapted to receive the VGA signal from the VGA signal transmitting unit, and include a detection signal into the VGA signal to form a combination signal. A transmitting control unit is connected to the VGA signal processing unit and the HDMI signal transmitting unit. The transmitting control unit is adapted to receive the combination signal and the VGA signal, to distinguish the combination signal and the VGA signal, and to output the combination signal and the VGA signal to the appropriate receivers.

Abstract: A power supply circuit for protecting a battery from current leakage when the battery is not in use includes a control signal input circuit and a switch circuit. The control signal input circuit receives a first control signal from a chip and output a second control signal. The switch circuit receives the second control signal and turns on or off an electronic connection between the battery and the chip. Wherein when the battery is not in use and not being charged by the adaptor, there is a possibility of current leakage from the battery. In such case, the switch circuit turns off the electronic connection between the battery and the chip, and the battery does not provide power to the chip.
