  • Method for digital transmission and display of weather imagery
    Patent number: 7039505
    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.

  • Computer method and apparatus for aircraft mixture leaning
    Patent number: 7039518
    Abstract: A computer implemented lean assist function monitors exhaust gas temperature in a plurality of cylinders in an engine along with fuel flow. The lean assist function automatically detects whether the pilot is leaning for best power or best economy and provides an indication to the pilot when the desired fuel mixture has been achieved based on the monitored temperatures.

  • Display method and system with select lighting to denote button action
    Publication number: 20050264529
    Abstract: Button action in a display system is dynamically denoted by either illuminating or not illuminating an illuminable element adjacent to the button to provide a lighting effect around the periphery of the button. The illumination of an illuminable element adjacent to an active button has the effect of drawing attention to an active button. Active buttons are dynamically updated based upon the state of the system and/or the particular page displayed.

  • Method and apparatus for calculating engine power
    Publication number: 20040254692
    Abstract: A method, computer program, or apparatus for determining with various degrees of precision the power delivered by an engine, typically, an aircraft engine. The disclosed invention uses a variety of parameters, such as the rotation rate, manifold pressure, outside air temperature, and fuel flow to determine or approximate the power delivered by the engine. The engine's altitude does not have to be involved in the calculations.

  • 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.

  • Displaying lightning strikes
    Patent number: 6606564
    Abstract: Lightning strikes are displayed as uniformly-structured (e.g., gaussian) kernels that decay in size and intensity over time. The lightning strikes may be displayed as they occur, or stored for later display. Overlapping areas of the kernels are displayed in different colors than corresponding non-overlapping areas. A color (or colors) displayed in an overlapping area is a function of the number of kernels that overlap in that area.
