  • Multiple configurable I/O common mezzanine cards
    Patent number: 7082487
    Abstract: CMC boards have standardized dimensions for an “I/O envelope” (to accommodate components for I/O functions) and a “component envelope” (to accommodate components for core board functions). Daughter cards are developed (mainly to perform I/O functions but also to perform core board functions, if desired) that fit within the standardized dimensions of the I/O envelope.
    Type: Grant

    Date of Patent: July 25, 2006
    Assignee: Spectrum Signal Processing, Inc.
    Inventors: Mohammad Darwish, Leonard G. Pucker, Phillip D. Smith, Roy Gee Leong Woo

  • Device for and method of detecting motion in an image
    Patent number: 6298144
    Abstract: A device for and method of detecting motion between a reference image and a test image by acquiring the images; aligning the images; dividing the images into blocks; masking certain blocks; differencing corresponding blocks; median filtering the differences; low-pass filtering the outputs of the median filter; generating a normalized histogram for each output of the low-pass filter; generating a model of gaussian noise; calculating the distance between the noise model and each normalized histogram; comparing each distance calculated to a user-definable threshold; and determining if motion has occurred between the images if a certain number of distance calculations are at or above the user-definable threshold. If a scene is to be continuously monitored and no motion occurred between the previous reference image and the previous test image then a new test image is acquired and compared against the previous reference image as described above.
