  • Logic configured for complimenting data on a bus when threshold exceeded
    Patent number: 7047345
    Abstract: A system includes logic configured for counting transitions between data on a bus and data to be put onto the bus. Where the counted transitions exceed a threshold, the data to be put onto the bus is complemented. As a result, complemented data is put on the bus where the threshold was exceeded and un-complemented data is put on the bus where the threshold was not exceeded.

  • Method and system for controlling the output of a diffractive light device
    Publication number: 20060022966
    Abstract: A method and system for controlling a color of light output by a diffractive light device (DLD device). The color is determined by a gap voltage applied to the DLD device. During each of a number of time frames, one of a number of control bits in a control word is sent to bit line logic corresponding to the DLD device. Each of the control bits represents a gap voltage level. The applied gap voltage is then adjusted to the gap voltage level represented by the one of the number of the control bits.

  • Address generation in a light modulator
    Publication number: 20060022965
    Abstract: A light modulator includes a control unit configured to receive an image input signal, and an array having a plurality of pixels arranged in a plurality of rows. The control unit is configured to provide a first address associated with the image input signal to the array in response to detecting a first mode of operation, and the control unit is configured to provide a second address associated with the image input signal to the array in response to detecting a second mode of operation. The array is configured to drive a first one of the plurality of rows in response to receiving the first address, and the array is configured to drive the first one of the plurality of rows and a second one of the plurality of rows in response to receiving the second address.

  • Data bus configuration
    Publication number: 20050188181
    Abstract: A system includes logic configured for counting transitions between data on a bus and data to be put onto the bus. Where the counted transitions exceed a threshold, the data to be put onto the bus is complemented. As a result, complemented data is put on the bus where the threshold was exceeded and un-complemented data is put on the bus where the threshold was not exceeded.
