摘要： Various embodiments set forth computer vision systems. In some embodiments, one or more activation maps are generated based on eye gaze data and used to control operation of one or more sensors. Each activation map indicates a highest density for acquiring sensor data in a region corresponding to an eye gaze direction and lower densities for acquiring sensor data in other regions. After the sensor data is acquired, a processing pipeline sub-samples (or bins) and processes regions of the acquired sensor data at different ratios based on the eye gaze direction. The sub-sampled (or binned) data for each region is processed independently, and results of the processing are combined to generate processed data, such as an image that can be displayed to a user.

摘要： Hyperlapse imaging is described. A device may include a camera, an ambient light sensor (ALS), and a data store. The camera is configured to capture images. The ALS is configured to detect associated ambient light properties for at least some of the captured images. The data store is configured to store the captured images and the associated ambient light properties. After a threshold amount, the stored captured images and the associated ambient light properties are processed in bulk to generate a hyperlapse video.

摘要： A control system for a vehicle includes a time sensitive network switch and one or more processors. The time sensitive network switch is configured to receive sensor data from light detection and ranging (LIDAR) sensors, radio detection and ranging (RADAR) sensors, or image sensors. The sensor data is representative of estimated objects that are in an external environment of the autonomous vehicle. The one or more processors are configured to receive the sensor data and determine instructions to control movement of the autonomous vehicle at least partially based on the sensor data from the time sensitive network switch and at least partially based on map data.

摘要： An apparatus, system, and method for detecting glints includes a pair of light sources positioned on a head-mounted frame and driven to illuminate a corneal surface of an eye with differential light signals. An image sensor is positioned on the head-mounted frame to receive reflections of the differential light signals from the corneal surface. An orientation of a cornea (e.g., corneal sphere) of the eye may be determined at least partially based on the reflections of the differential light signals.

摘要： Coherent light (e.g., laser light) is emitted into a tissue sample through an optical fiber. The tissue sample diffuses the coherent light. Different blood flow quantities generate different coherent light interference patterns. An image of a coherent light interference pattern is captured with an image sensor coupled to an optical fiber. The speckle contrast of the image quantifies coherent light interference pattern. The speckle contrast is determined and is mapped to blood flow quantities using one or more data models. A quantity of blood flow is identified in a tissue sample at least partially based on the speckle contrast value of the captured image.

摘要： An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.

摘要： A thermal-optical phase shifter includes a substrate layer, a cladding layer, and a beam in the cladding layer. The thermal-optical phase shifter includes a waveguide and a heating element disposed in the beam. The thermal-optical phase shifter includes a thermally conductive structure disposed on the cladding layer to disperse heat from the beam. The thermally conductive structure may include a metal strip disposed longitudinally along the beam, may include thermally conductive pads, and/or may include thermally conductive vias coupled between the cladding layer and the substrate layer. The thermal-optical phase shifter may be incorporated into light detection and ranging (LIDAR) devices, telecommunications devices, and/or computing devices.
