  • Patent number: 10785473
    Abstract: A virtual window display includes: a plurality of collimated projector modules having contiguous exit pupils. Each collimated projector module includes: a display device configured to display a spatially modulated image along a flat or curved geometric image surface, and one or more optical lenses sharing a common curvature symmetry axis and configured to optically collimate light from the display device in the collimated projector module. The curvature symmetry axes of the plurality of collimated projector modules point in a plurality of angular directions and are substantially convergent along at least one axis at a finite distance from the plurality of collimated projectors. The total display FOV of the virtual window display is larger than the module FOV of each of the plurality of collimated projector modules.

  • Patent number: 10636390
    Abstract: A display integrity system for use in a mounting adapter configured to mount a personal electronic device (PED) on an aircraft is disclosed. The display integrity system includes a transparent surface configured to overlay the display surface of a PED when the PED is mounted in the mounting adapter. The transparent surface includes one or more regions embedded with one or more coating layers that when activated with a select excitation wavelength are configured to emit visible light to annunciate a message indicating a problem with an image displayed on the PED. The display integrity system further includes a lighting source housed in the mounting adapter and configured to provide light in the select excitation wavelength when activated to illuminate the transparent surface and an imaging device mounted in the mounting adapter and configured to capture an image of the PED display for transmission to a server for integrity checking.

  • Publication number: 20200065044
    Abstract: A method for verifying the integrity, continuity, and availability (ICA) of information displayed on an uncertified display is provided. The method comprises creating, on the high integrity device, application data for display on an uncertified display device; transmitting the application data to the uncertified display device for display; receiving, at the high integrity device from the uncertified display device, a captured image of the display captured using a screen capture feature on the uncertified display device; determining, at the high integrity device, an expected display image; comparing, at the high integrity device, the captured image of the display to the expected display image; identifying, at the high integrity device, a loss of ICA if one or more frames in the captured image fails the comparison with the expected display image; and causing the annunciation of a message indicating the loss of ICA when a loss of ICA is identified.

  • Patent number: 10459224
    Abstract: A system and method of displaying a conformal-capable head-up display image is provided. Distortions caused by combiner curvature, for example, are removed by pre-distorting and projecting separate images for each eye. Shutter-based eyewear controls the visibility as the imagery is cycled, e.g., shuttered, between left and right eyes. The combined image generator, projector and eyewear system maintains minimal vergence errors, minimal dipvergence errors, acceptable average transmittance, and optionally, high conformality.

  • Patent number: 10338337
    Abstract: A display system configured for displaying critical aeronautical information on an aircraft display that is not certified for displaying critical aeronautical information comprises a mounting adapter and an application server. The mounting adapter is configured to mount, in an aircraft cockpit, a personal electronic device (PED) wherein the PED is not certified to display critical aeronautical information. The mounting adapter further comprises a surface with an actuatable covering that is configured to be overlaid on a PED display and an actuation source configured to actuate the covering. The application server is configured to execute a module that generates critical aeronautical information, transmit the generated critical aeronautical information to the PED for display, determine whether a problem exists with the image displayed on the PED display, and enable the actuation source to cause the covering to annunciate a message indicating a problem with the image displayed on the PED display.

  • Patent number: 10089927
    Abstract: An improved AM OLED pixel circuit and method of wide dynamic range dimming for AM OLED displays are disclosed that maintain color balance throughout the dimming range, and also maintain the uniformity of the luminance and chromaticity of the display at low gray-levels as the display is dimmed to lower luminance values. As such, AM OLED displays can meet the stringent color/dimming specifications required for existing and future avionics, cockpit, and hand-held military device display applications. Essentially, the OLED pixel circuit and method of dimming that are disclosed use Pulse Width Modulation (PWM) of the OLED pixel current to achieve the desired display luminance. Two example circuits are disclosed that externally PW modulate the common cathode voltage or common power supply voltage to modulate the OLED current in order to achieve the desired display luminance.
