  • Publication number: 20180342878
    Abstract: A power transmitter according to an aspect of the present disclosure includes a first coil to wirelessly transmit power to a second coil of a power receiver; a converter to receive direct current (DC) power, convert the DC power into alternating current (AC) power, and supply the AC power to the first coil; and a controller to execute power control for causing power supplied to a load to approach desired power. The controller executes frequency control of the AC power and at least one control of phase shift control of the converter and voltage control of the DC power as the power control. When the power supplied to the load cannot be caused to approach the desired power by the frequency control, the controller executes at least one of the phase shift control and the voltage control.

  • Publication number: 20180241301
    Abstract: A power transmitter according to one aspect of the disclosure includes: a power converter that converts a first AC power supplied from an AC power source into a DC power; a first detector that detects an electric current of the DC power; a feedback signal generator that generates a feedback signal based on the electric current of the DC power; and a controller that performs a feedback control on the electric power supplied to a power receiver based on the feedback signal. The feedback signal generator generates a canceling waveform to reduce a ripple caused to the DC power due to zero crossing of a voltage of the first AC power and generates the feedback signal based on the electric current of the DC power and the canceling waveform.

  • Patent number: 8004568
    Abstract: In an image pick-up apparatus of the invention, when capturing is started, a chapter formation-commanding portion transfers a chapter table to a memory. When a user depresses a chapter formation button, a chapter is formed in an empty table of the chapter table. After completion of the capturing, the chapter formation-commanding portion transfers the chapter table stored in the memory to a storage portion.

  • Patent number: 7869697
    Abstract: From a time point at which a storage capacity reaches a certain remaining capacity with respect to a limit value of 4 GB per one file depending on a file system, a subtraction time-managing portion (100A) changes photographing elapsed time display (174) which is displayed on a display picture of a liquid crystal display portion (17) to subtraction time display (178) in which residual time until 4 GB is reached is continuously subtracted in the inside of a portable image pickup device (1). Hence, a photographer can be visually informed of timing at which the photographing blank time period will occur. As a result, the photographer can be previously given the opportunity for the judgment about whether the photographing should be continuously performed or the current photographing should be ended to start new photographing.
