    摘要: A charge control circuit for controlling a micro-electromechanical system (MEMS) device having variable capacitor formed by first conductive plate and a second conductive plate separated by a variable gap distance. The charge control circuit comprises a switch circuit configured to receive a reference voltage having a selected voltage level and configured to respond to an enable signal having a duration at least as long as an electrical time constant constant of the MEMS device, but shorter than a mechanical time constant of the MEMS device, to apply the selected voltage level across the first and second plates for the duration to thereby cause a stored charge having a desired magnitude to accumulate on the variable capacitor, wherein the variable gap distance is a function of the magnitude of the stored charge.

    摘要: A light delivery device defining an optical path with a feedback device is disclosed. The feedback device dispatches actual illumination characteristics of the light delivery device to a control system, which compares the actual illumination characteristics with desired illumination characteristics to determine an offset for driving the light delivery device.

    摘要: Disclosed are embodiments of a system and method for processing an image. An image processing unit includes a processor unit and a control unit. The processor unit receives an incoming video signal. The control unit defines image frames from the video signal. The image frames have bit planes in a plurality of spatial segments for manifestation on a spatial light modulator. The control unit also defines on and off states for a solid state light source. The control unit modulates the solid state light source at a modulated level during at least one bit plane such that illumination of the solid state light source at the modulated level is equally applied during the at least one bit plane for each of the plurality of spatial segments.
