  • Method, apparatus, and system for automatic retinal image analysis
    Patent number: 8355544
    Abstract: Disclosed embodiments include a method for retinal image analysis implemented in a medical system with one or more processors comprising the method steps of: (a) locating an optical disk on the retinal images and establishing a plurality of circumferences centered at the disk; (b) detecting a plurality of vessels within a region defined by said circumferences' radii using a crease-based algorithm; (c) extracting a plurality of vessel segments based on a deformable models (snakes) algorithm; and d) automatically classifying the vessels and computing clinical parameters.
    Type: Grant

  • GAUGE ASSEMBLY AND METHODS OF USING SAME
    Publication number: 20100294037
    Abstract: A gauge assembly measuring an amount of a liquid, for use with a float arm assembly including a float arm pivoting in response to a change in the level of liquid, and a flange housing a first magnet and coupled to the float arm where the movement of the float arm causes a displacement of the first magnet. The gauge assembly includes a support adapted to be attached to the flange, which includes a second magnet, spaced in relationship to the first magnet and having a different strength than the first magnet, and an electronic circuit positioned proximate to the first and second magnets to provide a signal representative of the position of the second magnet wherein the second magnet is displaced by the first magnet in response to the level of liquid. The gauge assembly includes a display associated with the second magnet for showing the level of liquid.
