  • Publication number: 20240297507
    Abstract: An electronic device with hybrid power source includes a system circuit, a charging and discharging circuit, a power connector, two batteries, and a controller. The charging and discharging circuit is connected to the system circuit, the power connector, and the two batteries. The controller is connected to the processor and the charging and discharging circuit, and the controller has a hybrid power supply mode. The controller detects the operating power of the processor in the system circuit, and controls the power mode from a single power mode to a hybrid power supply mode in response to that the operating power reaches or exceeds the power threshold. In the hybrid power supply mode, under control of the controller, the processor releases a power limit, and the charging and discharging circuit powers the system circuit by using both the battery with greater energy level and an external power.

  • Patent number: 12040717
    Abstract: An electrical power conversion device, a function triggering circuit for the electrical power conversion device, and a function triggering method for the electrical power conversion device are provided. The function triggering circuit is coupled between the secondary side of the transformer and the control module and includes a current detection circuit, a delay circuit and a switching circuit. The current detection circuit senses the secondary side of the transformer to generate a detection signal of delay. Before steady-state duty of the transformer, the delay circuit causes an initial level to be higher than an internal level. After steady-state duty of the transformer, the switching circuit selectively generates a function triggering signal according to the detection signal. The function triggering signal is for triggering the control module to carry out an overcurrent protection operation.

  • Patent number: 12026851
    Abstract: A single image deraining method is proposed. A wavelet transforming step processes an initial rain image to generate an i-th stage low-frequency rain image and a plurality of i-th stage high-frequency rain images. An image deraining step inputs the i-th stage low-frequency rain image to a low-frequency deraining model to output an i-th stage low-frequency derain image. A first inverse wavelet transforming step recombines the n-th stage low-frequency derain image with the n-th stage high-frequency derain images to form an n-th stage derain image. A weighted blending step blends a (n?1)-th stage low-frequency derain image with the n-th stage derain image to generate a (n?1)-th stage blended derain image. A second inverse wavelet transforming step recombines the (n?1)-th stage high-frequency derain images with the (n?1)-th stage blended derain image to form a (n?1)-th stage derain image, and sets n to n?1 and repeats the last two steps.
