Abstract: A micro-LED device and a method of fabricating the micro-LED device are disclosed. The method includes processing from a first side (e.g., p-side) of epitaxial layers of a micro-LED wafer to form individual mesa structures and a first solid metal bonding layer on the mesa structures, bonding a second solid metal bonding layer on a backplane wafer to the first solid metal bonding layer of the micro-LED wafer, removing the substrate of the micro-LED wafer and processing from a second side (e.g., n-side) of the epitaxial layers to isolate the solid metal bonding layers and form individual electrodes (e.g., anodes) for individual micro-LEDs, forming a dielectric material layer on surfaces in regions between the mesa structures, and depositing one or more metal materials in the regions between the mesa structures to form mesa sidewall reflectors and a common electrode for the micro-LEDs.

Abstract: Controlling an avatar in an XR environment can be based on input(s) from external, non-XR computing devices, such as mobile devices. An external device can capture sensor data, audio data, and/or image data, which are processed by an avatar control system to determine a gesture performed by the user, gauge the level of intensity or excitement of the user, and/or infer the user's sentiment or emotional state. The avatar control system can generate a motion plan based on these inferences drawn from the external device sensor data based on a baseline animation or motion template. The system can generate avatar animations that have exaggerated or understated expressions relative to the user's real-world gestures, possibly exceeding limitations of a kinematic model that otherwise constrain the avatar's animations. The technology can enable users to control an avatar in an XR environment without specialized XR equipment.

Abstract: Disclosed herein are aspects related to a device that can include a wireless communication interface and one or more processors. The wireless communication interface can transmit, using a wireless connection with a remote device, one or more data elements to the remote device. The one or more processors can identify a condition of the wireless connection, determine a rate, for transmission of the one or more data elements, based at least on the condition, retrieve a signal from the remote device indicative of at least one criterion for use of the one or more data elements, update the rate based at least on the at least one criterion to determine an updated rate for transmission of the one or more data elements to the remote device, and cause the wireless communication interface to transmit, at the updated rate, the one or more data elements to the remote device.

Abstract: A high frequency, high efficiency, near field wireless charging system and interface for battery-powered wearable devices are provided. A number of various magnetic core, multi-winding transmitter coil, receiver coil configurations may be used with the transmitter coils generating a charge voltage at the receiver coils through magnetic flux. In some configurations, a buck-boost assisted transmitter, or a buck-boost split between transmitter and receiver charging system may be used. In other configurations, a switch-cap boost block on the transmitter side may be used to increase efficiency. In yet other configurations, a dual path charging system (e.g., for smart glass temples) or a dual transmitter—single receiver charging system with buck-boost or switch-cap blocks may be used. The transmitter-receiver pair configurations may also be used to charge a battery module to be inserted into a wearable device.

Abstract: Apparatuses include a package substrate with package bonding pads and a die electrically coupled to the package substrate via conductive bonding elements. The die includes a first application-specific integrated circuit (ASIC) with first die input/output pads and a second ASIC with second die input/output pads. Each of the first die input/output pads is electrically coupled to at least one corresponding package bonding pad. At least one of the second die input/output pads is not electrically coupled to any package bonding pad, such that the second ASIC is left in an inoperable state.

Abstract: Time-of-Flight (TOF) light pulses are emitted at a first temporal pulsing frequency and a second temporal pulsing frequency. ToF return signals are detected by a light detector of a ToF sensor and a wrapped histogram may be generated. As part of generating unwrapped histograms, a selected index may be identified to provide a ToF distance from ToF distances of the ToF return signals.

Abstract: An artificial reality system receives information identifying a physical object and location information describing a geographical location associated with the artificial reality system, in which the information identifying the physical object includes a trackable feature associated with the physical object. Upon receiving a request from a user to locate the physical object, the artificial reality system determines a most recent geographical location associated with the physical object based at least in part on the trackable feature and the location information. The artificial reality system then communicates a set of spatial audio cues to the user, in which the set of spatial audio cues guides the user to the most recent geographical location associated with the physical object.
