  • Patent number: 9007327
    Abstract: An apparatus for controlling an aviation display is provided. The apparatus includes processing electronics configured to cause a first representation of a first aviation data to be shown in a first format of the first aviation data, and to cause, in response to a first user input in relation to the first format, a second representation of the first aviation data to be shown in a second format of the first aviation data, the second format of the first aviation data comprising a first predefined location on a first region of a display.

  • Patent number: 8681290
    Abstract: The present invention is a display assembly in which a backlight module generates light beams via a light source. The light source provides the light beams to a light guide of the backlight module. The light guide then provides the light beams to a display panel of the display assembly for illuminating the display panel. One or more optical elements are implemented between the light source and an insertion edge of the light guide for promoting improved light insertion efficiency for the display assembly. Further, the optical element(s) may promote improvements in color quality, luminance and/or uniformity of graphics or graphical depictions displayed by the display assembly.

  • Patent number: 8633913
    Abstract: An apparatus for controlling an aviation display is provided. The apparatus includes processing electronics configured to cause a first representation of aviation data to be shown in a first format and to cause, in response to a user input relative to the first format, a second representation of the aviation data to be shown in a second format, in a predefined location on a region of an aircraft display.
