  • Camera support mechanism
    Patent number: 7572073
    Abstract: In some embodiments, a camera support mechanism may be used as a mount to couple a camera to a display. The camera support mechanism may include a front lip and rear leg to hold the camera in place. The front lip may align with a front edge of a display. In some embodiments, the rear leg may be adjustable by an adjustment knob. The rear leg may further have a compliant tip to allow the camera support mechanism to adapt to different sizes and shapes of displays. The camera may be mounted on the camera support mechanism through a fastener.

  • Arbitrary surface optical element and method of making the same
    Patent number: 7324734
    Abstract: An arbitrary surface optical element, such as a mirror for use in a rear projection television, includes a non-optical portion and an optical portion. The non-optical portion circumscribes the optical portion and has a thickness greater than the optical portion. Accordingly, the two portions cool at approximately the same rate, thereby minimizing warpage from differential cooling.
