Abstract: A prefetcher for a coprocessor is disclosed. An apparatus includes a processor and a coprocessor that are configured to execute processor and coprocessor instructions, respectively. The processor and coprocessor instructions appear together in code sequences fetched by the processor, with the coprocessor instructions being provided to the coprocessor by the processor. The apparatus further includes a coprocessor prefetcher configured to monitor a code sequence fetched by the processor and, in response to identifying a presence of coprocessor instructions in the code sequence, capture the memory addresses, generated by the processor, of operand data for coprocessor instructions. The coprocessor is further configured to issue, for a cache memory accessible to the coprocessor, prefetches for data associated with the memory addresses prior to execution of the coprocessor instructions by the coprocessor.

Abstract: Detecting a touch includes receiving image data of a touching object of a user selecting selectable objects of a target surface, determining a rate of movement of the touching object, in response to determining that the rate of movement satisfies a predetermined threshold, modifying a touch detection parameter for detecting a touch event between the touching object and the target surface, and detecting one or more additional touch events using the modified touch detection parameter.

Abstract: A computer input system includes a mouse including a housing having an interior surface defining an internal volume and a sensor assembly disposed in the internal volume. A processor is electrically coupled to the sensor assembly and a memory component having electronic instructions stored thereon that, when executed by the processor, causes the processor to determine an orientation of the mouse relative to a hand based on a touch input from the hand detected by the sensor assembly. The mouse can also have a circular array of touch sensors or lights that detect hand position and provide orientation information to the user.

Abstract: An electronic device may include a display with a display panel that emits light into an optical system. The system provides the light and world light to an eye box. The system may be implemented using a folded birdbath architecture. The system may include a partial reflector and a reflective polarizer in freeform curved rotationally asymmetric surfaces. The system may include two or three optical wedges. An air gap may separate two of the wedges. A quarter waveplate may be layered over the reflective polarizer and/or the partial reflector. A privacy filter may overlap the partial reflector. The wedges may perform total internal reflections on the light. The system may provide a horizontal field of view of the light to the eye box at a different point than a vertical field of view. A switchable shutter may overlap the system and may be synchronized to an external device display.

Abstract: In a head-mounted device, position and motion sensors may be included to determine the orientation of the head-mounted device. A motion sensor may experience error that accumulates over time, sometimes referred to as drift. To mitigate the effect of drift in a motion sensor, a reference orientation for the motion sensor may be reset when a qualifying motion is detected. The qualifying motion may be detected using one or more criteria such as a total change in angular orientation or rate of change in angular orientation. The reference orientation for the motion sensor may also be reset when a duration of time elapses without a qualifying motion being detected.

Abstract: A display may include a waveguide that directs image light to an eye box. The waveguide may include an optical coupler that redirects and replicates the light. The coupler may include a surface relief grating (SRG). The SRG may have a pitch that varies continuously along an axis orthogonal its ridges. The pitch may vary sinusoidally, linearly, parabolically, or according to other continuous and differentiable functions of position along the axis. The SRG may diffract the light. Upon diffracting the light, the SRG may impart a phase to the light. The phase may vary continuously as a function of position along a first axis and may, if desired, vary continuously as a function of position along a second axis orthogonal to the first axis. The SRG may prevent formation of coherent light paths after replication, thereby maximizing the efficiency of the system.

Abstract: Some examples of the disclosure are directed to systems and methods for displaying one or more user interfaces based on a context of an electronic device within a physical environment. In some examples, the electronic device detects initiation of an exercise activity associated with a user of the electronic device, optionally while a computer-generated environment is presented at the electronic device. In some examples, in response to detecting the initiation of the exercise activity, the electronic device activates an exercise tracking mode of operation. In some examples, while the exercise tracking mode of operation is active, the electronic device captures one or more images of a physical environment. In some examples, in accordance with detecting, in the one or more images, a feature of the physical environment, the electronic device performs a first operation associated with the exercise tracking mode of operation.

Abstract: A user equipment (UE) implementing power control for a 2-step random access channel (RACH) procedure is provided. The UE determines a first transmission power of a physical random access channel (PRACH) preamble to be used during a 2-step RACH procedure. The UE determines a second transmission power of a physical uplink shared channel (PUSCH) transmission to be used during the 2-step RACH procedure based on the first transmission power of the PRACH preamble. The UE then performs the 2-step RACH procedure based on the first transmission power of the PRACH preamble and the second transmission power of the PUSCH transmission. The UE switches to a 4-step RACH procedure from the 2-step RACH procedure based on a determination that the PRACH preamble was successfully detected and the PUSCH transmission was falsely detected, and performs the 4-step RACH procedure based on the first transmission power of the PRACH preamble.
