A transmission coil is mounted in a wireless power supply apparatus, and is configured to transmit an electric power signal including any one from among an electric field, a magnetic field, and an electromagnetic field. The transmission coil includes a loop coil and a magnetic member. The magnetic member is configured to cover a particular portion of the loop coil. For example, the loop coil may be configured to have a shape in which a first side and a second side are substantially in parallel with each other. The magnetic member may be configured to cover the first side of the loop coil.

Provided are a focusing position determining apparatus, an imaging apparatus, and a focusing position determining method, the method including setting an aperture to a first aperture value; driving a focus lens through a first range of positions as a first drive; during the first drive, obtaining images periodically, and calculating a first sampling of contrast values from the obtained images; calculating a first focus position from the first sampling of contrast values; setting the aperture to a second aperture value; driving a focus lens through a second range of positions as a second drive, the second range of positions being based on the first focus position; during the second drive, obtaining images periodically, and calculating a second sampling of contrast values from the obtained images; calculating a focusing position from the second sampling of contrast values; and driving the focus lens to the calculated focusing position.
摘要:
A wireless power supply apparatus transmits an electric power signal including any one of an electric field, a magnetic field, and an electromagnetic field. A bridge circuit includes multiple switches. A control unit performs switching control of the multiple switches of the bridge circuit at a first frequency configured as a transmission frequency. A transmission coil and a resonance capacitor form a resonance antenna, which is connected to the bridge circuit. The resonance frequency of the resonance antenna thus formed is a second frequency that is equal to or higher than the first frequency. A control unit is configured to be capable of adjusting the length of the dead time during which the multiple switches are all turned off at the same time.
