  • Patent number: 11940520
    Abstract: For a complex image to be complexly added, appropriate phase correction is executed by a simple method to prevent occurrence of an artifact in a signal region and to reduce noise in a background region. Two or more types of smoothing processing with different smoothing degrees are executed on a phase image of the complex image to obtain two or more types of smoothed phase images having different smoothing degrees. A weight for each of these smoothed phase images is calculated based on a signal value (SNR) of an intensity image, and addition is performed by a weight for each signal value to obtain a smoothed phase image for correction. After a phase of the complex image is corrected using the smoothed phase image, a phase-corrected complex image is complexly added. As a result, phase correction equivalent to phase correction in which a smoothing degree is weakened in the signal region and a smoothing degree is strengthened in the background region is realized.

  • Publication number: 20230194619
    Abstract: The battery system includes a secondary battery, a voltage sensor, a current sensor, a temperature sensor, and a processor. The processor is configured to calculate a polarization overvoltage by subtracting a voltage drop amount caused by a DC resistance and a reactive resistance of the secondary battery determined in accordance with a temperature and an SOC of the secondary battery from a voltage difference between OCV and CCV of the secondary battery.

  • Publication number: 20220381836
    Abstract: A battery control device includes a processor that is configured to estimate a full charge capacity of a battery based on an amount of current supplied to the battery from a start of charging to an end of charging and voltages of the battery at the start of charging and the end of charging when the battery is charged from a state where a voltage of the battery is below a predetermined start voltage threshold value to a state where the voltage exceeds a predetermined end voltage threshold value, and the battery satisfies a predetermined permission condition.

  • Patent number: 10991295
    Abstract: A display driver (100) drives a liquid crystal panel (200) that is driven by a static drive method. The display driver (100) includes an interface circuit (110), a selection circuit (120), and a drive circuit (130). The interface circuit (110) receives instruction information and display data from the outside. The selection circuit (120) selects n pieces of selected duty ratio data, which are n pieces of duty ratio data of k pieces of duty ratio data, based on the instruction information. The drive circuit (130) selects output duty ratio data corresponding to a tone value indicated by the display data from the n pieces of selected duty ratio data, and performs PWM driving of the liquid crystal panel (200) by outputting a drive signal having a duty ratio indicated by the selected output duty ratio data.
