摘要： A light source structure includes a vertical cavity surface-emitting laser (VCSEL) device having a top surface and at least one side surface substantially perpendicular to and adjoining the top surface. The VCSEL device is configurable to output directed emission of light through the top surface. The light source structure also includes a light barrier surrounding at least a top portion of the VCSEL device and separated from the at least one side surface. The light barrier is configured to receive spontaneous emission out of the VCSEL device through the at least one side surface.

摘要： A communication system provides audio content to one or more client devices capable of playing spatialized audio content. For example, the communication system receives audio content from a client device and transmits the audio content to other client devices to be played for users. The communication system dynamically modifies audio content transmitted to different client devices based on a payload including audio parameters (e.g., local area acoustic properties, an audiogram for a user, a head related transfer function for a user, etc.) received from a client device.

摘要： A circuit may be configured to reduce current leakage. The circuit may include a bias generator, a charge interface, and a charge controller. The bias generator may be coupled to a first voltage source and configured to generate a first current and provide a first voltage. The charge interface may be communicatively coupled to the bias generator and configured to mirror the first current into a second current. The charge controller may be communicatively coupled to the charge interface and configured to receive the second current from the charge interface and provide a second voltage. The bias generator may be further configured to perform an ultra-low leakage switching operation in which the first voltage is switched to a third voltage while reducing a first possibility of band-band tunneling leakage at the charge interface.

摘要： A method may be performed by a leakage monitoring and compensation system configured to estimate and compensate for leakage current in memory unit cells. The method may include identifying a leakage monitoring component associated with a memory unit cell. Further, the method may include sampling multiple leak events during a first exposure window. The method may include storing a first count representing the plurality of leak events sampled during the first exposure window. Each leak event may correspond to a unit of memory leakage. The method may include sampling multiple sensing events during a second exposure window. The method may include detecting a second count representing the sensing events sampled during the second exposure window. The method may include determining a compensation value representing a difference between the first count and the second count.

摘要： A system for implementing an augmented reality (AR)/virtual reality (VR) display includes a hardware (HW) architecture that employs a system-on-chip (SoC) to compose and submit textures. The SoC composes and submits textures by using display serial interface (DSI) display lines to transmit the textures to a physical display. Software (SW) architecture includes a stack display architecture with an applications level using the surface rendered by applications, a display service level to compose superframes, provide an abstraction layer on top of a surface flinger (SL) application programming interface (API), and allow assignment of textures and metadata to different hardware planes, and a driver level. The system uses the surfaces or enhanced effects that are rendered by the applications or the compositor, depending on the type of the application, and computes the metadata related to the location or coordinates.

摘要： A system is disclosed for using an audio time and level difference renderer (TLDR) to generate spatialized audio content for multiple channels from an audio signal received at a single channel. The system selects an audio TLDR from a set of audio TLDRs based on received input parameters. The system configures the selected audio TLDR based on received input parameters using a filter parameter model to generate a configured audio TLDR that comprises a set of configured binaural dynamic filters, and a configured delay between the multiple channel. The system applies the configured audio TLDR to an audio signal received at the single channel to generate spatialized multiple channel audio content for each channel of the multiple audio channel and presents the generated spatialized audio content at multiple channels to a user via a headset.

摘要： A method is disclosed for receiving a synchronization signal from a display circuit configured to display a series of frames, each frame comprising a plurality of tiles of pixels, determining, based on the received synchronization signal, that the display circuit has consumed data corresponding to one or more tiles of a frame, identifying a predetermined number of tiles that are subsequent to the one or more tiles consumed by the display circuit based on the synchronization signal, determining that one or more tiles of the identified tiles require an update, selectively rendering the determined tiles, and transmitting the rendered tiles to the display circuit.

摘要： A light-emitting diode (“LED”) package includes a package housing defining a space. The LED package includes a first LED disposed with the space defined by the package housing, and configured to emit a first light having a blue wavelength range. The blue wavelength range has a peak wavelength ranging from about 440 nm to about 480 nm. The LED package includes a second LED disposed within the space, and configured to emit a second light having a red wavelength range. The red wavelength range has a peak wavelength ranging from about 610 nm to about 680 nm. The LED package includes a phosphor filler filling the space and configured to absorb a portion of the first light to emit a third light having a green wavelength range. The green wavelength range has a peak wavelength ranging from about 510 nm to about 570 nm.
