Abstract:
A spatial light modulator (70) comprised of an array of micromirrors (72) each having support post (74). The support post (74) defines support post edges (76) in the upper surface of the mirrors (72). These support post edges (76) are all oriented at 45 degree angles with respect to an incident beam of light from a light source (80) to minimize diffraction of light from the edges (76) into the darkfield optics when the mirrors are oriented in the off-state. The present invention achieves an increased contrast ratio of about 20% over conventional designs.
Abstract:
A method of implementing pulse-width modulated image display systems (10, 20) with a spatial light modulator (SLM) (15) configured for split-reset addressing. Display frame periods are divided into time slices. Each frame of data is divided into bit-planes, each bit-plane having one bit of data for each pixel element and representing a bit weight of the intensity value to be displayed by that pixel element. Each bit-plane has a display time corresponding to a number of time slices, with bit-planes of higher bit weights being displayed for more time slices. The bit-planes are further formatted into reset groups, each reset group corresponding to a reset group of the SLM (15). The display times for reset groups of more significant bits are segmented so that the data can be displayed in segments rather than for a continuous time. During loading, segments of corresponding bit-planes are temporally aligned from one reset group to the next. The display times for less significant bits are not segmented but are temporally aligned to the extent possible without loading conflicts.
Abstract:
A digital video interface receiver adjusts a transfer function of a phase-locked loop circuit having a programmable charge pump, a programmable phase-locked loop filter, or a programmable gain voltage controlled oscillator. The digital video interface receiver monitors and detects errors in a data stream associated with the phase-locked loop circuit. Moreover, the digital video interface receiver changes the transfer function of the phase-locked loop circuit, in response to the detected errors, by changing parameters associated with the programmable charge pump, the programmable phase-locked loop filter, or the programmable gain voltage controlled oscillator of the phase-locked loop circuit so as to change the transfer function of the phase-locked loop circuit.

Abstract:
A system and method transmits graphic data received at varying frequencies at a fixed data rate. The frequency dependent data and associated data clock signal are received and the frequency dependent data is converted to frequency independent data. A ratio of a number of data clock cycles to a number of reference clock cycles is determined and transmitted. The frequency independent data and header data are transmitted, at a fixed rate, to a receiver, the fixed rate being a frequency greater than the frequency of the associated data clock signal. The received the frequency independent data is converted to frequency dependent data based upon the received determined ratio. The communication channel may include an optical fiber and a tension member wherein control data is transmitted along the tension member and graphic data is transmitted along the optical fiber.
