Abstract: A system for detecting a vehicle includes a light source configured to emit a light signal. The system also includes a receiver sensor configured to receive a reflected light signal based at least in part on the light signal reflected from a plurality of reflectors. The system also includes a controller, the controller configured to identify an arrangement pattern of the plurality of reflectors based at least in part on the reflected light signal and determine that plurality of reflectors are coupled to another vehicle based at least in part on an identification of the arrangement pattern.

Abstract: A facial recognition authentication process may utilize images of a user's face that are captured while the user is being illuminated using both flood infrared illumination and patterned illumination (e.g., speckle pattern illumination). As the user's face is illuminated by both flood infrared illumination and patterned illumination, the captured images may include both flood infrared illumination data and depth map image data. Flood infrared illumination data may be generated from the images to assess two-dimensional features of the user in the captured images. Depth map image data may be generated from the pattern data in the images to assess three-dimensional (depth) features of the user in the captured images. The flood infrared illumination data and the depth map image data may be used separately by facial recognition authentication process to attempt to authenticate the user in the captured images as an authorized user of the device.

Abstract: A light beam scanning device includes a controller device which dynamically adjusts a divergence of the beam. Divergence adjustment can include adjusting the beam divergence along one or more cross sectional axes of the beam. Beam divergence can be adjusted between consecutive scans, during a scan, etc. Beam divergence can be adjusted based on the field of view and scan rate. Beam divergence adjustment can enable dynamic adjustment of the spot size of the beam, which can enable the apparatus to adjust between scanning a wide divergence beam to detect objects in a scene and scanning a narrow divergence beam to generate detailed point clouds of the detected objects. Beam divergence adjustment can enable adjustment of reflection point intensity, enabling detection of low-reflectivity objects.

Abstract: An electronic device may have light-based components. The light-based components may include light sources, light detectors, and image sensors. The light-based components may be aligned with a window in the device. The window may be formed within an inactive area of a display or within other device structures. The window may have one or more window members mounted within an opening in a display layer in the inactive area. Visible light blocking material such as chalcogenide glass may be incorporated into the window to provide the window with an opaque appearance that matches the opaque appearance of surrounding portions of the inactive portion of the display. In configurations in which the light-based components include a visible image sensor or other visible light detecting component, the window may be provided with a portion that is transparent at visible wavelengths.

Abstract: A light beam scanning device includes a lens element assembly which dynamically adjusts a divergence of the beam. The lens element assembly can include multiple lens elements, one or more of which translates parallel to the light beam to adjust beam divergence. Divergence adjustment can include adjusting the beam divergence along one or more cross sectional axes of the beam. Beam divergence can be adjusted between consecutive scans, during a scan, etc. Beam divergence can be adjusted based on the field of view and scan rate. Beam divergence adjustment can enable dynamic adjustment of the spot size of the beam, which can enable the apparatus to adjust between scanning a wide divergence beam to detect objects in a scene and scanning a narrow divergence beam to generate detailed point clouds of the detected objects. Beam divergence adjustment can enable adjustment of reflection point intensity, enabling detection of low-reflectivity objects.
Abstract translation: 光束扫描装置包括动态调节光束发散的透镜元件组件。 透镜元件组件可以包括多个透镜元件，其中的一个或多个平行于光束平移以调节光束发散。 发散调整可以包括沿光束的一个或多个横截面轴调整光束发散。 可以在连续扫描之间，扫描期间调整光束发散等。可以根据视场和扫描速率调整光束发散。 光束发散调节可以使光束的光斑尺寸能够动态调节，这使得装置能够在扫描宽的发散光束之间进行调整，以检测场景中的物体并扫描窄的发散光束以产生被检测物体的详细点云。 光束发散调整可以调节反射点强度，从而能够检测低反射率物体。

Abstract: Methods and systems for multi-sensor real-time alignment and calibration are disclosed herein. A vehicle includes a projector configured to project a pattern on a target location. The vehicle also includes one or more sensors. The one or more sensors are configured to capture sensor data from the target location and detect the pattern at the target location. The vehicle further includes a calibration system configured to determine whether a particular sensor of the one or more sensors is out of alignment based on a relative position of the pattern as detected by the one or more sensors. The calibration system is also configured to, based on a determination that the particular sensor is out of alignment, adjust an alignment of the particular sensor based on the sensor data and the diffractive pattern.

Abstract: Subepidermal imaging of a face may be used to assess subepidermal features such as blood vessels (e.g., veins) when the device is attempting to authenticate a user in a facial recognition authentication process. Assessment of the subepidermal features may be used to distinguish between users that have closely related facial features (e.g., siblings or twins) in situations where the facial recognition authentication process has less certainty in a decision about recognition of the user's face as an authorized user.

Abstract: Aspects of the present disclosure involve example systems and methods for remote sensing of objects. In one example, a system includes a light source, a camera, a light radar (lidar) system, a region of interest identification circuit, and a range refining circuit. The region of interest identification circuit identifies a region of interest corresponding to an object and a first range of distance to the region of interest using the camera and the light source. The range refining circuit probes the region of interest to refine the first range to a second range of distance to the region of interest using the lidar system, the second range having a lower uncertainty than the first range.
