  • Patent number: 11130592
    Abstract: A method of avoiding Controlled Flight Into Terrain (CFIT) involves a step of equipping an aircraft with a radar based sensor positioned in an angular orientation directed forward and down, so as to detect ground objects ahead of the aircraft. The radar must have a range of at least 10 Kilometres. A processing unit monitors the radar 5 based sensor. A display remains in an inactive mode until the radar based sensor detects a ground object meeting predetermined parameters. Upon the radar based sensor detecting a ground object the processing unit is programmed to switch the display to the active mode and display a graphic representation of the ground object. The method puts the pilot on alert with an 10 accentuated and focused warning in sufficient time to take appropriate evasive action to avoid a ground obstacle.

  • Patent number: 10969675
    Abstract: An optical assembly includes a first optical waveguide, a first in-coupler coupled with the first optical waveguide and a projector configured to project image light toward a first side of the first optical waveguide. The optical assembly also includes a first scanning reflector optically coupled with the projector and disposed on a second side of the first optical waveguide that is opposite to the first side. The projector is configured to project image light. The first scanning reflector is configured to receive the image light and to redirect the image light across a first range of directions. The first in-coupler is configured to redirect a first portion of the image light so that the first portion of the image light undergoes total internal reflection inside the first optical waveguide.

  • Patent number: 10969593
    Abstract: A virtual reality/augmented reality (VR/AR) headset system (including the capability for one or both of virtual reality and augmented reality) includes a remote optical engine. The remote disposition of the optical engine removes many or all of the components of the VR/AR headset system that add weight, heat, and other characteristics that can add to user discomfort in using the system from the headset. An electronic image is received and/or generated remotely at the optical engine and is transmitted optically from the remote location to the headset to be viewed by the user. One or more optical waveguides may be used to transmit the electronic image to one or more passive displays of the headset, from the remote optical engine.

  • Patent number: 10967797
    Abstract: A video display mirror is provided with a half mirror, a monitor, and an interlocking mechanism. The half mirror is used so that a vehicle passenger can look toward the rear of the vehicle. The monitor is disposed near the half mirror toward the front of the vehicle. The interlocking mechanism moves in relation to a video image being displayed on the monitor and changes the angle of a reflection surface of the half mirror from the position of the half mirror when the rear of the vehicle is viewed.

  • Patent number: 10962782
    Abstract: Examples are disclosed that relate to expanding an exit pupil of a display device via a curved waveguide. One example provides a curved waveguide, including an input coupler configured to couple light into the curved waveguide, a first reflective surface, a second reflective surface opposing the first reflective surface, and an output coupler configured to couple the light out of the curved waveguide. The curved waveguide also has a curvature in a direction transverse to an optical path between the input coupler and the output coupler, the curvature having a radius that varies along a direction extending between the input coupler and the output coupler.

  • Patent number: 10963103
    Abstract: A display system comprises a light source assembly, a display assembly, a camera assembly, and a controller. The light source assembly is configured to generate visible light and infrared light. The display assembly is configured to generate image light using the visible light and to generate tracking light using the infrared light. The tracking light and the image light pass through a beam splitter prior to being projected into a local area. The camera assembly is configured to capture one or more images of the local area illuminated with the tracking light. The images are illuminated with the tracking light that passes through the beam splitter prior to be being captured by the camera assembly. The controller is configured to calculate depth information for objects in the local area using the one or more images.

    Abstract: An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.

  • Patent number: 10948994
    Abstract: When a location of a wearable system changes, the wearable system can ensure that a gesture working region always remains in a field of view of the wearable system. Therefore, the wearable system can still collect and recognize a gesture image and implement gesture control. The solution provided in this application is as follows: The wearable system creates a gesture working region and a region of interest, where the region of interest is within a shooting area of a first camera, and the first camera is included in a wearable device; obtains a location parameter of the wearable system; adjusts the region of interest according to the location parameter, so that the region of interest covers the gesture working region; collects a gesture image within the gesture working region; recognizes the gesture image to obtain a gesture instruction; and performs a corresponding operation according to the gesture instruction.
