  • Publication number: 20220343816
    Abstract: An apparatus that supplies multi-plane images for viewing by a user includes an image generator, an image director, and a first output port. The image generator generates a first image to be seen by the user as being a first distance from a user point of view, and a second image to be seen by the user as being a second distance from the user point of view The first image is comprised of a number of optical wavelength components, and the second image is comprised of the number of optical wavelength components. The image director is configured to direct the first image to traverse a first optical path to the first output port of the apparatus, and to direct the second image to traverse a second optical path to the first output port of the apparatus. The first optical path corresponds to the first distance and the second optical path corresponds to the second distance. The first optical path and the second optical path have different lengths.

  • Publication number: 20220222923
    Abstract: An object detection device has a controller configured to receive classification data and regions for an image. The regions are prioritized and if a region is selected for further prediction, a photographic feature for the selected region is determined and a re-capture of the selected region is made based on the photographic feature by updating an image capturing device. The re-captured region is re-processed and classification data is re-generated. Then, final object detection for selected region(s) is performed and final object detection for not-selected region(s) is performed.

  • Publication number: 20210350730
    Abstract: A viewing device comprising a controller, a transparent display and a visual shutter. The controller is configured to determine a color of virtual content to be displayed; determine a background color contrasting the virtual content displayed; determine a display area corresponding to where the virtual content is to be displayed; cause the visual shutter to enable a background to the virtual content to be displayed, the background having the contrasting background color thereby providing a contrasting background to the displayed virtual content (DVC); and to cause the transparent display to display virtual content for overlapping at least one visual object (VO) perceivable through the transparent display at least partially onto the background. The visual shutter is configured to enable the background by operating in a mode wherein at least a portion of the visual shutter is blocked to obstruct the VO in the blocked portion of the visual shutter.

  • Publication number: 20210337097
    Abstract: Analog power savings is achieved by pre-charging only those pixels of a sensor array that are needed as determined responsive to any one of a power configuration, image size, image position of interest, desired/selected frame rate, desired/selected resolution, etc. To that end, the solution presented herein selects one or more sensor segments, each comprising a subset of pixels of the sensor array, and only pre-charges the pixels in the selected segment(s). In so doing, the solution presented herein provides a power savings proportional to the number of uncharged pixel circuits.

  • Patent number: 10958340
    Abstract: Devices implementing light communications use waveguides to efficiently collect wavelength-specific light used for the light communications and propagate that collected light to a sensor. More particularly, light comprising a plurality of wavelengths and collected from one or more entrances propagates along a TIR waveguide until disrupted by a diffusive element, which effectively directs the propagating light to one or more sensors. Each sensor detects a subset of the plurality of wavelengths. In so doing, the solution presented herein increases the amount of light available for the light communications and/or reduces the number of sensors needed for the light communications, e.g., by providing light collected from multiple different locations to a single sensor.

  • Patent number: 10895701
    Abstract: The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide. In so doing, the solution presented herein increases the amount of light available for light communications. Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.
