Abstract: A vehicle to be driven by electric power which is wirelessly transmitted from a power transmitter having two transmission electrodes includes: two reception electrodes to receive AC power from the two transmission electrodes through capacitive coupling respectively with the two transmission electrodes; a power receiving circuit which is connected to the two reception electrodes to convert AC power received by the two reception electrodes into DC power or another form of AC power, and supply the DC power or other form of AC power to an electric motor which drives the vehicle; and a control circuit which, while the vehicle is traveling over the two transmission electrodes, increases an impedance of the vehicle as viewed from the power transmitter when a value of at least one of power, voltage and current in the power receiving circuit, or a change rate over time thereof, exceeds a threshold value.

Abstract: A power receiving device includes: a power receiving antenna to wirelessly receive AC power from a power transmitting antenna in the power transmitting device; a power receiving circuit to convert the AC power received by the power receiving antenna into DC power and to output the DC power; an impedance adjustment circuit disposed on a transmission path between a load that utilizes the DC power and the power receiving antenna, the impedance adjustment circuit being capable of causing a change in input impedance thereof; and a power reception control circuit to control the impedance adjustment circuit. The power reception control circuit consecutively changes a value of the input impedance of the impedance adjustment circuit to a value selected from among a plurality of values, determines from among the plurality of values a value at which power to be supplied to the load becomes largest, and sets and maintains the input impedance at an operating impedance value that is based on the determined value.

Abstract: A power transmission apparatus oscillates alternating current power at a first frequency (f1) which is lower than a resonant frequency (fr) of the second resonator and at a second frequency (f2) which is higher than the resonant frequency (fr). The power transmission apparatus measures an inductance value Lin (f1) and an inductance value Lin (f2). The inductance value Lin (f1) is measured when the oscillation circuit oscillates alternating current power at the first frequency (f1), and the inductance value Lin (f2) is measured when the oscillation circuit oscillates alternating current power at the second frequency (f2). The power transmission apparatus calculates a coupling coefficient k by using an expression represented by k2=1−Lin(f2)/Lin(f1), to detect relative position of the second resonator to the first resonator on the basis of the coupling coefficient k.

Abstract: A power transmission device includes an inverter, an oscillator, a foreign substance detector, and a power transmission control circuitry. The power transmission control circuitry causes the foreign substance detector to perform a series of multiple processes and determine whether a foreign substance is present before a transmission of first AC power starts, and then causes the inverter to start the transmission of the first AC power. After the transmission starts, a detection period in which foreign substance detecting is performed and a power transmission period in which transmission of the first AC power is performed are repeated. The series of multiple processes is divided and performed in the multiple repeated detecting periods. The foreign substance detector is caused to divide and perform the series of multiple processes using the detecting periods and determine whether a foreign substance is present.

Abstract: A control method for a power transmitting device is provided, the power transmitting device including a power transmitting antenna, which transmits AC power wirelessly to the power receiving antenna of a power receiving device, and an oscillator. The method includes supplying pulse signals that control first and second switching element groups to the oscillator, and changing a phase shift amount between a first pulse signal and a second pulse signal. The method also includes causing the oscillator to change the voltage of the AC power output and to set an initial value of the phase shift amount. The method further includes causing the oscillator to output preliminary AC power of a voltage to reduce the phase shift amount from the initial value, fixing the phase shift amount, and causing the oscillator to output the AC power while maintaining the voltage corresponding to the fixed phase shift amount.

Abstract: To provide a voltage-type device for killing microorganisms in which a microorganism killing effect is high and scale is less likely to clog up through holes in electrodes. The device for killing microorganisms includes: a main body which a liquid to be treated flows in at one end and flows out at the other end; opposed electrodes that are arranged in the main body in parallel with a flow of the liquid to be treated and have mutually-opposed through holes; and a voltage source of which an anode is connected to one of the opposed electrodes and a cathode is connected to the other of them. When a straightened liquid to be treated is passed through the device for killing microorganisms, a stirring action is produced between the opposed electrodes, whereby hypochlorous acid can be diffused throughout the entire device and a high killing effect can be obtained.
