Abstract: An electronic device such as a head-mounted device may have gaze tracking sensors and other circuits that include packaged light-emitting devices. The packaged light-emitting devices may each include a light-emitting component such as a light-emitting diode or laser that emits infrared light or light of other wavelengths. The packaged light-emitting devices may have protection circuitry. The protection circuitry of each device may include one or more sensors such as a package integrity sensor, a proximity sensor, a photodetector for measuring emitted light intensity, a temperature sensor for measuring a temperature associated with the light-emitting component, and a current sensor. A control circuit such as an integrated circuit containing a comparator or other analog circuitry and/or a digital control circuit may gather information from one or more of the sensors and may control the light-emitting component based on the sensor information to prevent elevated light emission intensities.

Abstract: A communications network may include user equipment (UE) devices. When a first UE device becomes off-grid and has an emergency message, the first UE device may transmit device-to-device signals for receipt by a second UE device. The signals may include one or more preambles that precede the emergency message and that are used by the second UE device to perform synchronization with the first UE device. The second UE device may periodically activate a receiver during a series of windows to listen for the signals, may receive a preamble sequence during one of the windows, and may synchronize its timing to the first UE device for receipt of the emergency message based on the preamble sequence. This may allow the UE devices to be synchronized for transfer of the emergency message over long distances while consuming a minimal amount of power on the second UE device.

Abstract: Embodiments of the present disclosure relate to debugging of an accelerator circuit using a packet limit breakpoint. A vector circuit reads a subset of instruction packets from an instruction memory and receives a portion of input data from a data memory corresponding to the subset of instruction packets. The vector circuit executes a set of vector operations in accordance with multiple instruction packets from the subset using data from the received portion of input data identified in the multiple instruction packets to generate output data. A program counter control circuit coupled to the instruction memory triggers a breakpoint in a program stored in the instruction memory causing the accelerator circuit to stop executing remaining instruction packets in the program following the multiple instruction packets responsive to a number of instruction packets executed in the program from a time instant of an event reaching a predetermined number.

The method further includes determining that a service period associated with the TWT process has started and transmitting, in accordance with the TWT process, the one or more multicast packets during the service period, where the one or more transmitted multicast packets are addressed to the group of electronic devices.

Abstract: A system comprises a prediction module configured to predict an attribute value, such as a texture coordinate, for a vertex of a triangle in a two-dimensional (2D) attribute representation based on known positions of vertices of a corresponding triangle in a three-dimensional (3D) geometric representation. In some embodiments, the prediction module adaptively selects a prediction technique between multiple available prediction techniques based on availability of vertices information in the 3D geometric representation and in the 2D attribute representation and further based on compression efficiency and distortion minimization. The prediction module enables compression of attribute information being signaled for volumetric visual content, such as a mesh with texture.

Abstract: A loudspeaker having a compressible lead wire is described. The lead wire carries an electrical audio input signal to a voice coil. The electrical audio input signal drives the voice coil to oscillate in an axial direction. The compressible lead wire includes an elastic portion that stretches and compresses in the axial direction to allow the voice coil to oscillate freely. The elastic portion includes several compressible elements that are located within a cavity of the loudspeaker. The compressible elements extend through the cavity in the axial direction. Other aspects are also described and claimed.

Abstract: In some implementations, a computing device can be configured to automatically turn off notifications when generating a notification would cause a disturbance or be unwanted by a user. The device can be configured with quiet hours during which notifications that would otherwise be generated by the computing device can be suppressed. In some implementations, quiet hours can be configured as a time period with a start time and an end time. In some implementations, quiet hours can be derived from application data. For example, calendar data, alarm clock data, map data, etc. can be used to determine when quiet hours should be enforced. In some implementations, the device can be configured with exceptions to quiet hour notification suppression. In some implementations, the user can identify contacts to which the quiet hours notification suppression should not be applied.

Abstract: Techniques for scheduling memory operations are disclosed in which alternate read/write commands within a multi-bank memory operation are delayed beyond a minimum timing parameter in order to increase memory data bus utilization. The remaining read/write commands are not delayed beyond the minimum timing parameter. Every other clock cycle (e.g., even clock cycles) within the memory operation is reserved for activate commands, while other commands such as sync and read/write are scheduled on the intervening clock cycles (e.g., odd clock cycles). For memory devices for which a sync command (which causes a clock of the memory data bus to start) is to precede a corresponding read/write command by a number of clock cycles that would place it in a cycle reserved for activate commands, a particular operation mode is disclosed in which the memory device internally delays a received sync command.

An update to the plurality of confidence values is detected, wherein the updated plurality of confidence values includes a third confidence value associated with a third data item of the plurality of ordered data items. In accordance with a determination that the third confidence value is higher than a first confidence value of the first data item, an order of the plurality of ordered data items is modified, and the third data item of the plurality of ordered data items is displayed.
