Abstract: Object detection may include transmitting, by a first device, a first pulse into an environment using a wide field configuration of an ultrasonic sensor array, detecting a presence of an object in the environment based on a detected echo based on the first pulse. In response to detecting the presence of the object, a targeted configuration of the ultrasonic sensor array is determined, and a second pulse is transmitted into the environment based on the second pulse, wherein a characteristic of the object is determined based on a detected echo from the second pulse.

Abstract: A display system includes a head-mounted display unit and a wake control system. The head-mounted display unit provides content to a user and is operable in a low-power state and a high-power state that consumes more power to provide the content to the user than the low-power state. The wake control system determines when to operate in the high-power state. The wake control system may assess a first wake criterion with low power, assess a second wake criterion with higher power than the first wake criterion upon satisfaction of the first wake criterion, and cause the head-mounted display unit to operate in the high-power state upon satisfaction of the second wake criterion.

Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

Abstract: A system such as a vehicle system, building, or electrical equipment may be provided with one or more optical components. The optical components may include a near-infrared camera or other components that operate at near-infrared wavelengths. A visible-light-reflecting-and-infrared-light-transmitting layer may overlap the optical component. The visible-light-reflecting-and-infrared-light-transmitting layer may have an infrared-transparent substrate. A polymer layer may be formed on the substrate and may contain plasmonic nanoparticles that reflect white light. Colorant may be incorporated into the polymer layer or into an additional polymer coating to impart a desired color to the reflected white light and thereby provide the visible-light-reflecting-and-infrared-light-transmitting layer with a desired appearance.

Abstract: Systems are presented for improving side mirror functionality of a vehicle. In one embodiment, the systems involve a side mirror with an adjustable profile. The systems include an actuator for altering the adjustable profile of a mirror in response to signals from a sensor (e.g., a camera). The mirror is coupled to a side of the vehicle through the actuator. In another embodiment, the systems involve an integrated side mirror. The systems include a first transmissive optic, a second transmissive optic, and at least one optical element that enable a field of view to be seen through a portion of the vehicle. In an additional embodiment, the systems involve a display system for integrating side-mirror functionality into a display image. The display system includes an image processing unit and a display unit for forming a display image at a location visible to a driver. The display image includes a field of view imaged by a sensor. Other systems are presented.

Abstract: Lighting may be provided using light sources such as lighting systems with arrays of light-emitting diodes. A lighting system may be integrated into a seat, a door panel, a dashboard, or other interior portions of a system such as a vehicle. The interior portions of the vehicle may be illuminated using lighting systems to provide ambient light, to provide custom surface textures and other decorative patterns, to provide icons, text, and other information, and to provide custom gauges and other illuminated regions. Illuminated regions may overlap sensors such as capacitive touch sensors, force sensors, and other sensors. The light-emitting diodes in a lighting system may supply light that passes through openings in a cover layer. The layer may be formed from fabric, leather, or other materials. Lens structures may guide light through the openings.

Abstract: A vehicle may have a head-up display that produces a display output allowing a viewer in the vehicle to observe two-dimensional or three-dimensional content. The head-up display may include a display unit that produces the display output and an optical combiner on a vehicle window that directs the display output towards the viewer. The optical combiner may be a holographic or diffractive optical element or may be an array of angled reflectors such as micromirrors embedded in an index-matching material. Optical combiners formed from holographic elements may be configured to reflect light at an angle of reflection that is different than the angle of incidence, thereby allowing light to reach a viewer's eyes even when the head-up display reflects light off of a side window on a vehicle door. A holographic optical element may include volume holographic media such as photopolymers or holographic polymer dispersed liquid crystal.

Abstract: A vehicle may have vehicle controls that are used in steering, braking, and accelerating the vehicle. The vehicle may have sensors that gather information on vehicle speed, orientation, and position. The sensors may also gather information on relative speed between the vehicle and a following vehicle, information on risks of a collision between a vehicle and an external object, and other vehicle status information and vehicle operating environment information. Control circuitry may use light-based devices to display braking information, information on vehicle speed, the relative speed between a vehicle and a following vehicle, autonomous driving mode status information, custom brake light information or other user-selected information, or other information on vehicle status and the operating environment of a vehicle.

Abstract: A vehicle may have optical structures such as windows and mirrors that have the potential to allow glare from external objects to shine into the eyes of a driver or other vehicle occupant. A control circuit may gather information on where the eyes of the driver are located using a camera mounted in the vehicle and may gather information on where the sun or other source of glare are located outside of the vehicle. Based on this information, the control circuit may direct a light modulator on a window or mirror to selectively darken an area that prevents the glare from reaching the eyes of the driver. The light modulator may have a photochromic layer that is adjusted by shining light onto the photochromic layer, may be a liquid crystal modulator, an electrochromic modulator, or other light modulator layer.
