Publication number: 20240406304Abstract: A computer system detects a first event. In response to detecting the first event: if first criteria are met as a result of the first event, wherein the first criteria require that the orientation of the display generation component is a first orientation, and that the computer system is charging, in order for the first criteria to be met, the computer system displays a first customizable user interface that was not displayed prior to detecting the first event; and, if the first criteria are not met as a result of the first event, the computer system forgoes displaying the first customizable user interface.Type: ApplicationFiled: May 6, 2024Publication date: December 5, 2024Inventors: Christopher P.

Patent number: 11979679Abstract: A system for merging a plurality of image sources into a single image stream defines a predistortion image mask for each source. Each mask defines a distorted image space to account for distortion in the display optics, and indicates a region or regions in the desired output image where one merge method should be used versus another (e.g., overlay vs. replace). Each source mask may have a separate level of granularity according to the requirements of the included image and corresponding distortion.Type: GrantFiled: July 9, 2021Date of Patent: May 7, 2024Assignee: Rockwell Collins, Inc.Inventors: Brent Hansen, Michael A. Ropers

Patent number: 11462192Abstract: 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.Type: GrantFiled: May 13, 2021Date of Patent: October 4, 2022Assignee: Rockwell Collins, Inc.Inventors: Joshua Gerdes, Donald E Mosier, Christopher A.

Patent number: 11386835Abstract: 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.Type: GrantFiled: March 23, 2021Date of Patent: July 12, 2022Assignee: Rockwell Collins, Inc.Inventors: Donald E.

Patent number: 11340459Abstract: 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.Type: GrantFiled: March 6, 2020Date of Patent: May 24, 2022Assignee: Rockwell Collins, Inc.Inventors: Bobby D.

Patent number: 11254440Abstract: 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.Type: GrantFiled: August 7, 2019Date of Patent: February 22, 2022Assignee: Rockwell Collins, Inc.Inventor: Michael A.

Patent number: 11036453Abstract: 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.Type: GrantFiled: October 28, 2019Date of Patent: June 15, 2021Assignee: Rockwell Collins, Inc.Inventors: Andrew M.
