    Abstract: An antenna system with a switchable horizontal half-power beamwidth includes: a ground plane module including rows of patch groups that jointly form a ground plane; an antenna unit spaced apart from the ground plane by an interval; and a control module that can receive at least one beam control message. Each two adjacent rows of the patch groups are provided therebetween with at least one switching unit. The control module can bring each of the at least one switching unit to be turned on or turned off according to contents of the at least one beam control message, so as to adjust the electrical properties of the ground plane and change the horizontal half-power beamwidth of the antenna unit. Accordingly, the antenna system has a relatively low-profile spatial property, and requires no extra mechanism design for horizontal half-power beamwidth adjustment and switching based on practical needs.

  • Patent number: 12260526
    Abstract: One embodiment provides a computer-implemented method that includes providing a dynamic list structure that stores one or more detected object bounding boxes. Temporal analysis is applied that updates the dynamic list structure with object validation to reduce temporal artifacts. A two-dimensional (2D) buffer is utilized to store a luminance reduction ratio of a whole video frame. The luminance reduction ratio is applied to each pixel in the whole video frame based on the 2D buffer. One or more spatial smoothing filters are applied to the 2D buffer to reduce a likelihood of one or more spatial artifacts occurring in a luminance reduced region.
