  • Patent number: 11598973
    Abstract: A system for forming a homogenized illumination line which can be imaged as a low-speckle line is disclosed. The system includes a laser configured to emit a collimated laser beam; and an illumination-fan generator that includes one or more linear diffusers. The illumination-fan generator is arranged and configured to (i) receive the collimated laser beam, (ii) output a planar fan of diffused light, such that the planar fan emanates from a light line formed on the distal-most one of the one or more linear diffusers, and (iii) cause formation of an illumination line at an intersection of the planar fan and an object.

  • Patent number: 11598976
    Abstract: A wearable or a mobile device includes a camera to capture an image of a scene with an unknown object. Execution of programming by a processor configures the device to perform functions, including a function to capture, via the camera, the image of the scene with the unknown object. To create lightweight human-machine user interactions, execution of programming by the processor further configures the device to determine a recognized object-based adjustment; and produce visible output to the user via the graphical user interface presented on the image display of the device based on the recognized object-based adjustment. Examples of recognized object-based adjustments include launch, hide, or display of an application for the user to interact with or utilize; display of a menu of applications related to the recognized object for execution; or enable or disable of a system level feature.

  • Patent number: 11598985
    Abstract: A system such as a vehicle, building, or electronic device system may have a support structure with one or more windows. The support structure and window may separate an interior region within the system from a surrounding exterior region. Control circuitry may receive input such as user input and may adjust an adjustable layer in the window based on the input. The adjustable layer may have a polymer matrix layer with embedded cells. The cells may include intermixed guest-host liquid crystal cells and liquid crystal cells. The guest-host liquid crystal cells and liquid crystal cells may have different liquid crystal materials and/or different sizes that allow the guest-host liquid crystal cells and liquid crystal cells to electrically switch states at different respective threshold voltages. Based on the user input or other input the control circuitry can adjust a drive signal across the adjustable layer to change light transmittance and haze.
