    Abstract: Aspects of the subject technology relate to electronic devices with pressure sensors. Pressure sensor occlusion may be mitigated by ejecting occluding liquid with pulsed liquid heating. Processing circuit of the electronic device can obtain pressure sensor data from the pressure sensor and determine that the opening is occluded based at least in part on a change in pressure within a cavity adjacent the opening. The processing circuitry applies a first power pulse to a heating element during a first phase to cause the heating element to form a gas pocket around the heating element by heating at least a portion of a water volume inside the cavity and applies a second power pulse to the heating element during a second phase following the first phase to cause the heating element to expand the gas pocket around the heating element by further heating the water volume inside the cavity.

    Abstract: Electrodes that can be used to determine a first type of physiological signal and a second type of physiological signal are disclosed. The first type of physiological signal can be electromyography (EMG) signals produced by activity of muscles and tendons. Identification of hand movements can be supplemented with pose detection circuitry such as inertial measurement units (IMUs). These EMG signals can be processed to identify hand movements and recognize gestures associated with those hand movements. The second type of physiological signal can be electromyography (ECG) signals produced by the heart. The electrodes can be used to detect EMG and ECG signals dependent upon a current configuration of sensing circuitry. The electrodes can be used to determine a measurement quality associated with the EMG signals.

    Abstract: This application describes methods and apparatus to allocate uplink (UL) power dynamically across multiple parallel radio frequency links for wireless devices. The wireless device sets an initial maximum transmit power level (MTPL) for each UL radio link of multiple radio links used for UL traffic based on a duty cycle prediction for the respective UL radio link. The wireless device adjusts the initial MTPL for each UL radio link based on a predicted data throughput for the UL radio link relative to a total predicted data throughput for all UL radio links. The adjusted MTPL for each UL radio link can be also reduced when the UL radio link uses UL multiple input multiple output (MIMO) transmission via multiple antenna ports, e.g., by apportioning the adjusted MTPL among the multiple antenna ports of the UL radio link equally.

    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for triggering a change in beam configuration based on UL beam conditions. The UE may detect an unsafe UL beam condition for an UL beam based, at least in part, on an MPE level being exceeded by the UL beam. In response to the detection, remedial actions that to alleviate the unsafe UL beam condition may be performed. The remedial actions may prioritize UL beam quality over DL beam quality and may include reducing a transmit power of the UL beam based on an MPR, triggering an intra-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, triggering an inter-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, and/or signaling a beam failure to a network serving the UE.

    Abstract: In an example computer-implemented method, a management module receives measurement data from one or more first network modules of a wireless communications network. The measurement data pertains to at least one of establishing one or more communications sessions on the wireless communications network by the one or more first network modules, or modifying one or more communications sessions on the wireless communications network by the one or more first network modules. The management module generates one or more performance metrics based on the measurement data, and transmits the one or more performance metrics to one or more second network modules of the wireless communications network.
