  • Patent number: 11855388
    Abstract: A floating electrical connector includes a housing with a tubular portion. An axis is defined in a center of the tubular portion. Several floating terminals are arranged around the axis and are partially connected. Each floating terminal has an inner terminal sheet on an inner side and a spring structure on an outer side. Each spring structure is connected to one of the inner terminal sheets. A portion of the inner terminal sheet is inserted into the tubular portion and arranged along an inner peripheral surface of the tubular portion. The portion of each inner terminal sheet located in the tubular portion has an electronic contact bulging inward. Several external pins are electrically connected around the floating terminals. When a conductive pin is inserted into the tubular portion, the spring structures could elastically deform, allowing the tubular portion to adapt to a horizontal deviation or a skew deviation of the conductive pin, providing a greater tolerance for alignment deviations.

  • Publication number: 20230269908
    Abstract: A heat dissipation device includes a vapor chamber for contacting a heat source; at least one heat pipe having a first end and a second end connected to the vapor chamber; at least one partition disposed inside the heat pipe to partition the inside of the heat pipe into a first channel and a second channel isolated from each other; and a heat dissipation fin set disposed on the vapor chamber and partially covers the heat pipe. The vapor chamber is filled with a liquid working medium that absorbs the heat of the heat source and then gasifies into a gaseous working medium. The gaseous working medium moves into the first channel and the second channel to be condensed by the heat dissipation fin set, so the gaseous working medium is liquefied into the liquid working medium, and then the liquid working medium flows back into the vapor chamber.

  • Patent number: 11711613
    Abstract: Image frames for computational photography may be corrected, such as through rolling shutter correction (RSC), prior to fusion of the image frames to reduce wobble and jitter artifacts present in a video sequence of HDR-enhanced image frames. First and second motion data regarding motion of the image capture device may be determined for times corresponding to the capturing of the first and second image frames, respectively. The rolling shutter correction (RSC) may be applied to the first and second image frames based on both the first and second motion data. The corrected first and second image frames may then be aligned and fused to obtain a single output image frame with higher dynamic range than either of the first or second image frames.

  • Patent number: 11582405
    Abstract: A transformer may transform image data from a first color pattern to a second color pattern. The transforming of image data may be applied to image data received from a memory storing an array of intensities corresponding to a first color pattern of a first color filter array (CFA) of an image sensor to a second color pattern. The second color pattern may be a color pattern of a size smaller that the first CFA. Remosaicing may be applied to the second color pattern to obtain image data organized in a Bayer color pattern. The transforming may be configured to operate on data from an image sensor to obtain different zoom levels not available without applying a digital zoom algorithm that involve upscaling, which reduces the image quality of the image data.
