Brian Eckersley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Digital projection equipment and techniques
    Patent number: 7224411
    Abstract: Apparatus and techniques for enhancing characteristics of electronic projection systems are detailed. Included among the techniques are both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. Pre-modulators and polarizing beam splitters also may be used as parts of the innovative systems.

  • Display apparatus for displaying an image representative of an interlaced video signal
    Patent number: 6580470
    Abstract: A display apparatus includes means for inputting an interlaced video signal comprising signals representative of successive fields in image data produced by scanning successive image frames. Fields of image data that have been derived from single frames of the scanned image frames are determined, and signals produced representative of each of the image frames. A DMD for each color channel is addressed with signals representative of the frames.

  • Display device driving circuitry and method
    Patent number: 6057816
    Abstract: A method and apparatus for driving a display device including a matrix array of deflectable mirror devices is described. The deflectable mirror devices are divided into blocks of N rows. Selected groups of mirror devices within each block are loaded with single bit data in a cycle of loading operations During at least some of the loading operations, two series of reset cycles are used enabling one single bit cycle in one group to terminate and another single bit cycle in another group to commence within a single loading operation. Active bit data may be loaded and displayed in the otherwise unused time intervals between the active bits.

  • Display device using time division modulation to display grey scale
    Patent number: 5986640
    Abstract: A display device includes a deformable mirror device wherein grey scales are displayed using a time division modulation process in which the times or sub-frame periods for which each mirror within the deformable mirror array is switched on. The device includes a selection means for ordering selected sub-frame periods or divided sub-frame periods such that the light directed from each mirror is substantially temporally balanced during each frame period of the display device and/or between consecutive frame periods.
