  • Synchronization of MEMS projector slow axis mirror to input video frame rate
    Patent number: 11054635
    Abstract: A system includes a mirror controller driving fast and slow axis mirrors of a projector with fast and slow axis drive signals to reflect a collimated light beam in a scan pattern across the target. The scan pattern includes trace lines which cause display of an input video stream on the target, and retrace lines which operate to return the slow axis mirror to a proper location to begin a next frame of the scan pattern. The slow axis drive signal is generated to maintain a number of trace lines in each frame of the scan pattern constant across frames, but the slow axis drive signal is modified to lock a phase and frequency of the displayed video to a phase and frequency of the input video stream by changing a number of retrace lines in each frame of the scan pattern on a frame-by-frame basis by a non-integer number.

  • Scanning devices for ascertaining attributes of tangible objects
    Patent number: 11054370
    Abstract: A scanning device that has a housing including an opaque wall configured to position an imaging device (e.g., still or video camera) to capture an image of a tangible object, a staging area (e.g., transparent wall, opening) opposite of the opaque wall, and an opaque body extending between the opaque wall and the staging area. The scanning device has a chamber that enables the imaging device to capture the image relative to the staging area.
