  • Publication number: 20120267961
    Abstract: A resonance circuit includes a transmission coil and a resonance capacitor connected in series. A multi-tone power supply is capable of selecting arbitrary frequency components from among multiple discrete frequency components, and outputs, to the resonance circuit, a multi-tone signal obtained by superimposing sine wave signals of the respective frequency components thus selected. In a measurement mode, a frequency control circuit sets all the frequency components for the multi-tone power supply, and selects at least one frequency component at which the electric power transmission efficiency is high in the state in which a multi-tone signal is generated by superimposing the sine wave signals of all the frequencies. In a power supply mode, the aforementioned at least one frequency component thus selected in the measurement mode is set for the multi-tone power supply.

  • Publication number: 20120154647
    Abstract: An imaging apparatus and an imaging method, wherein a focus location direction discriminator estimates a direction toward a focus location based on two contrast evaluation values corresponding to two imaging optical systems having different image focusing locations. Therefore, the imaging apparatus and the imaging method can directly start an AF operation at current image focusing locations of two imaging optical systems, without setting the image focusing locations to fixed initial locations in a focusing operation of the imaging optical systems. As a result, AF operation time and power consumption are reduced without failing to find a direction of image focusing location.
