  • Method for digital transmission and display of weather imagery
    Patent number: 7668656
    Abstract: A method for creating minimal data representing a source image is presented. The source image is divided into a grid of cells. A color is selected for each cell corner based on sampling an area defined by the cell corner. An indication of the selected color is stored in an array dependent on the co-ordinates of the cell corner in the source image.
    Type: Grant
    Filed: February 26, 2008
    Date of Patent: February 23, 2010
    Assignee: Avidyne Corporation
    Inventors: David A. Southard, Lowell F. Bell, Michael A. Aucoin, Frédéric Gouin, Theodore H. Cannaday, Jr.

  • Beam width display method and system
    Patent number: 6614383
    Abstract: A weather radar display system displays a beam indicator indicative of a radar beam. The beam indicator represents width of the radar beam as a function of range (distance from the radar beam source). The beam indicator allows a pilot to easily discern accuracy of detected weather conditions based on the beam width.

  • Beam elevation display method and system
    Patent number: 6614382
    Abstract: The relative altitude of the center of a radar beam in relation to the aircraft's altitude at a plurality of distance ranges from the radar source is computed. A plurality of range rings representing the distance ranges are displayed. The computed relative altitude is displayed adjacent to each range ring displayed.
