  • Displays with pixels coupled by beam splitters
    Patent number: 11551592
    Abstract: An example device includes a main display panel that includes a main array of pixels and an opening within the main array of pixels. The example device further includes a beam splitter positioned to communicate light through the opening within the main array of pixels, a sensor positioned with respect to the beam splitter to capture light incident on the opening within the main array of pixels, and a subarray including a pixel. The subarray is positioned with respect to the beam splitter to output light through the opening within the main array of pixels.

  • Retrofittable power supply
    Patent number: 6781249
    Abstract: A retrofittable power supply allows an electronic device that is initially designed to be non-portable (in the sense that such electronic and electrical devices require a wired connection to an AC or DC power supply) to operate in geographical regions, or under conditions, in which a wired power supply is not available. The retroffitable power supply can simply plug into an existing case or frame of the non-portable electronic device, and can then serve as a means for powering both the non-portable electronic device, as well as a means for powering peripheral devices that may be coupled to the non-portable electronic device.
