  • Ambient light detection with digitized output
    Publication number: 20040195494
    Abstract: A system and method of ambient light detection with digitized output. A light sensitive device is coupled to electronic circuitry for receiving an output of the light sensitive device corresponding to a level of ambient light. The electronic circuitry compares the output to a threshold level. The threshold level corresponds to a desired level of light. The electronic circuitry for provides an output signal indicative of said desired level of light.

  • Single lens multiple light source device
    Publication number: 20040165277
    Abstract: An optical communication device having multiple light sources under a single lens. The optical communication device has two light sources. The optical communication device has a lens optically coupled to the two light sources. The lens is shaped to direct light from the two light sources towards an axis of the lens. The optical communication device further has a third light source located below the approximate center of the lens.
