  • Segmented illumination display
    Patent number: 11982814
    Abstract: A device having a see-through display including a segmented light source configured to provide additional control of an illumination level of an image display. The individual light segments of the light source are individually controlled to together produce a light beam that illuminates the image display to provide an additional range of control of the illumination level. An N number of light segments allow the minimum light level of the light beam to be 1/N of the minimum light the light source can generate. The maximum light level of the beam is N time brighter than a light source with only one light segment. The dynamic level of the image generated is matched to the ambient light about the device such that the image is visually acceptable to a user. The device can be eyewear in one example.

  • Integrated die-level cameras and methods of manufacturing the same
    Patent number: 8729653
    Abstract: An integrated die-level camera system and method of making the camera system include a first die-level camera formed at least partially in a die. A second die level camera is also formed at least partially in the die. Baffling is formed to block stray light between the first and second die-level cameras.
