    Abstract: A computer system (such as a controller) that selects channels and/or channel widths for use during communication in a shared band of frequencies is described. During operation, the computer system may receive, associated with access points in a region (such as a zone), information specifying unavailable channels associated with the shared band of frequencies, where the unavailable channels are currently used by the access points. For example, the information may be included in access-point status reports from the access points. Then, based at least in part on the unavailable channels, the computer system may determine the channels and/or the channel widths for use by the access points during communication in the shared band of frequencies in the region. Next, the computer system may provide, addressed to the access points, second information specifying the determined channels and/or the channel width.

  • Publication number: 20240085678
    Abstract: Various embodiments of the present disclosure are directed towards a camera module comprising flat lenses. Flat lenses have reduced thicknesses compared to other types of lenses, whereby the camera module may have a small size and camera bumps may be omitted or reduced in size on cell phones and the like incorporating the camera module. The flat lenses are configured to focus visible light into a beam of white light, split the beam into sub-beams of red, green, and blue light, and guide the sub-beams respectively to separate image sensors for red, green, and blue light. The image sensors generate images for corresponding colors and the images are combined into a full-color image. Optically splitting the beam into the sub-beams and using separate image sensors for the sub-beams allows color filters to be omitted and smaller pixel sensors. This, in turn, allows higher quality imaging.
