  • Patent number: 11460622
    Abstract: An electronic device such as a voice-controlled speaker device may have a housing. A speaker and other input-output components and control circuitry may be mounted within the housing. Light-emitting components may emit light that passes through a curved upper top cap portion or other housing structure. The light-emitting components may be interconnected using a flex circuit on a curved substrate or may be mounted on a planar circuit board. A subset of the light-emitting components may be rotated to improve color balance. Optical structures such as light guides, lens, microlenses, and/or a diffuser layer may be disposed over the light-emitting components to promote light mixing, to reduce hotspots, and to improve contrast on the top cap. The diffuser layer may be suspended using a support structure having baffle members to constraint the angular spread of the emitted light. Illuminated or persistently visible glyphs may be displayed in or near the top cap portion.

  • Patent number: 11462192
    Abstract: A system and method for monitoring the status of a pixelated display defines one or more pixel locations or clusters of pixels to be dithered. A monitor determines if the specified pixels or clusters of pixels demonstrate dithering. Detection of the expected dithering indicates a functional display while failure to detect the dithering indicates a failed display. Brightness levels are monitored to detect a failure in brightness leveling. Brightness is monitored at the same locations.

  • Patent number: 11386835
    Abstract: In a display with subpixel LEDs, each pixel includes two subpixel LEDs controlled via a shared control circuit and switching element. Switching element logic allows one set of brightness control transistors to alternatively control two subpixels. The driving and control elements of a display backplane are organized into pixels units of four driving elements and three control elements. Each pixel may comprise two green subpixels controlled via the switching element. Alternatively, each pixel may comprise a white subpixel that only illuminates when the colored pixels are off; the green and white subpixels are controlled via the switching element.

  • Patent number: 11340459
    Abstract: A helmet mounted display system is described. A visor has an inner reflective surface and is mountable to head gear. A light source is arranged to emit light. Directing optics are arranged to image light from the light source onto the inner reflective surface of the visor to provide a reticle image on the inner reflective surface of the visor. An eye tracker is configured to determine the orientation of an eye of a wearer of the head gear. A controller is configured to receive an indication of the determined orientation of the eye, and to control the at least one actuator to change the orientation and shape of the directing optics to change the position of reticle image based on the indication of the determined orientation of the eye such that the eye views the reticle image.

  • Patent number: 11302289
    Abstract: A system may include a display element. The display element may include pixel groups. Each of the pixel groups may include a first set of sub-pixels and a second set of sub-pixels. The first set of sub-pixels may include: a first sub-pixel; a second sub-pixel; and a third sub-pixel. The second set of sub-pixels may include: a fourth sub-pixel; a fifth sub-pixel; and a sixth sub-pixel. Each of the fourth sub-pixel, the fifth sub-pixel, and the sixth sub-pixel may have a maximum brightness that is dimmer than a maximum brightness of each of the first sub-pixel, the second sub-pixel, and the third sub-pixel. Some or all sub-pixels of one of the first set of sub-pixels or the second set of sub-pixels may be driven while all sub-pixels of the other of the first set of sub-pixels or the second set of sub-pixels are undriven.

  • Patent number: 11254440
    Abstract: A system and method for Automated Aerial Refueling (AAR) may combine unrelated capabilities to provide a high integrity solution to boom manipulation and insertion to couple with a receiver receptacle. Precise positioning systems on each aircraft coupled via data link provide a high integrity relative positioning solution generating a requisite integrity for positioning yet insufficient for boom insertion. High definition cameras onboard the tanker provide multi-wavelength remote vision digital images used to identify the boom fitting as well as the receptacle. Combined with boom position information from the tanker, the system determines pixel position inputs from stereo digital images to precisely identify the boom and receptacle and manipulate the boom to insert the boom fitting into the receptacle. Constant camera generated feedback and updated relative positioning alerts the system and disconnects the boom should the receiver aircraft stray outside the proper position.

  • Patent number: 11036453
    Abstract: A device and method for presentation of bezel embedded head tracking fiducials within an aircraft cockpit incorporates two and three-dimensional fiducial markers within a bezel of a forward display. Oriented in a constellation within a constant field of view of the pilot, the fiducials are specifically configured for continuous recognition by an optical sensor associated with a head worn display (HWD). With continuous constellation recognition, the HWD identifies the bezel embedded fiducials and determines a high integrity pose solution of a head reference frame relative to the aircraft enabling the system to present a high integrity primary flight display to the pilot without requiring an additional flight display available. Using active backlit short-wave infrared (SWIR) lighting and/or passively coated with reflective material specifically tuned to the night vision systems available to the HWD sensor, the bezel embedded fiducials allow operation of the HWD systems in any illumination environment.
