Abstract: Aspects of the subject technology relate to providing frame rate arbitration for electronic devices. Frame rate arbitration can include determining a global frame rate based on frame rate parameters from one or more animation sources, and providing the global frame rate to the animation sources. The frame rate parameters for various animations sources can have differing preferred, minimum, and/or maximum frame rates, and the global frame rate may be determined for concurrent display of multiple animations from the multiple animation sources. In one or more implementations, frame rate arbitration can also be performed based on frame rate parameters from an input source.

The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted de ice and the portable electronic device.

Abstract: Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.

Abstract: The present disclosure is directed to systems and methods for controlling a number of allowed downlink/uplink (DL/UL) switching points. For example, the method may include acquiring a shared channel occupancy time (COT) that includes one or more DL bursts and/or UL bursts. The method may also include utilizing one or more of the DL bursts or the UL bursts as a reference burst. The method may also include deriving a metric for controlling the number of DL/UL switching points in the shared COT based on the reference burst. The method may also include comparing the metric to a threshold value. The method may also include setting the number of DL/UL switching points in the shared COT based on the comparison of the metric to the threshold value.

The triplet may include a first antenna with a radiating element formed from a patch on the substrate and second and third antennas having radiating elements formed from patches on that extend across a smaller lateral area than the patch in the first antenna. The patches in the second and third antennas may have extended electrical lengths formed from parasitic patches embedded within the substrate that are coupled to opposing edges of the patches by fences of conductive vias. The antenna module may include phased antenna arrays for conveying centimeter/millimeter wave signals. Signal conductors for the antennas may be distributed across multiple metallization layers of the substrate.

Abstract: A reduced capacity (redcap) device may perform initial uplink communications, including transmitting a redcap physical uplink control channel (R-PUCCH), over an initial uplink bandwidth part (BWP) shared with a second device, the initial uplink BWP having a bandwidth (BW) larger than a maximum BW supported by the redcap device and smaller than or equal to a maximum BW supported by the second device. Frequency hopping operation for the redcap device may be supported for the R-PUCCH transmission through frequency division multiplexing and/or time division multiplexing settings for the resources used for the R-PUCCH transmission, and for PUCCH transmission by the second device. Restrictions may be implemented to create a gap for redcap devices to perform RF retuning between a physical RACH transmission and a subsequent physical control channel (e.g. PDCCH) monitoring for random access reception when the frequency gap is larger than the maximum BW supported by the redcap device.

Abstract: In some implementations, a first computing device can send notifications at times that the first computing device is not in an expected location. A user of a second computing device can remotely configure an expected location for the first computing device, which may be a particular location for a certain period of time. During that time, the first computing device can monitor its own location and check whether it is within the expected location. If the first computing device unexpectedly leaves or fails to enter the expected location, the first computing device may transmit a notification to the second computing device. Similarly, if the first computing device loses connectivity with other devices, a server device may notify the second computing device that the location of the first computing device cannot be determined.

Abstract: An electronic device may display a first lap time representation, and may move the first lap time representation in accordance with a first amount of elapsed time. While moving the first lap time representation, the electronic device may detect a lap input. In response to the lap input, the electronic device may cease movement of the first lap time representation, display a second lap time representation, and move the second lap time representation in accordance with a second amount of elapsed time. A relative positioning of the first lap time representation and the second lap time representation may correspond to a difference between a first lap time and a second lap time. In some embodiments, the electronic device may update the timescales of lap time representation(s) in accordance with a rotational input. In some embodiments, the electronic device may update a timer duration setting in accordance with a rotational input.

Abstract: Head-mounted devices can be formed as a modular system that provides a variety of different components and functions to achieve the results that are desired by a user. The modular configurations allow a user to easily customize a head-mounted device with one or more arm modules to provide features that integrate with other operations of the frame module of the head-mounted device. The arm modules can be easily exchanged with each other to provide different components and functions at different times. Accordingly, a frame module of a head-mounted device need not include permanent components that provide every function that will later be desired by the user. Instead, the head-mounted device can have expanded and customizable capabilities by the use of one or more arm modules.
