Abstract: An electronic device includes a pressure sensor and a processor. The pressure sensor is disposed within an interior volume of the electronic device and configured to generate a time-dependent sequence of measurements related to a force applied to the electronic device. The processor is configured to characterize, using at least the time-dependent sequence of measurements, a venting state of the interior volume. In some embodiments, the electronic device may also include a capacitive force sensor disposed to detect distortion of the interior volume. A second time-dependent sequence of measurements related to the force may be generated by the capacitive force sensor, and used by the processor to characterize the venting state of the interior volume.

Abstract: Keyboards, input devices, and related systems include key mechanisms with keycaps and actuators that provide adjustable feedback in response to user input. The actuators are controllable to provide variable tactile force or audible feedback that is dependent upon the user input. Encoders are able to transduce a location or relative position of a keycap as it is being pressed over time, and a signal is provided to actuators to cause them to provide feedback corresponding to the position of the keycap as it moves. The feedback can change the feel or sound of the keycap based on the keycap positions, time of operation, velocity, user identity, and other factors. Thus, the feel or sound of a keyboard or related input device can be adjusted electronically for efficient testing and increased user customization and feedback modes.

Abstract: Textured cover assemblies for electronic devices are disclosed. The textured cover assemblies may provide a combination of optical and tactile properties to the electronic devices. In some cases, a textured cover assembly may be provided over decorative coating.

Abstract: This disclosure is directed towards systems and methods that improve bandwidth shifting operations of an ADPLL without losing a lock of the ADPLL and having the benefit of being able to change the bandwidth an unlimited amount of times. Indeed, a processor may transmit amplification parameters to the ADPLL to implement a bandwidth shift. The shift may occur in response to a enable signal, such as a gear trigger control signal (gear_retime signal) or a enable signal generated to cause alignment of the shifting with a clock signal (e.g., enable signal generated by AND logic gates). These systems and methods described herein many enable multiple bandwidth changing operations to occur without compromising the complexity and footprint of the system.

Abstract: A communications system may include a satellite and user equipment (UE) devices. When the UE devices have uplink (UL) packets to transmit, each UE device may randomly select a time slot within a finite time window associated with a time reference of the satellite. The UE device may identify a path length between itself and the satellite and may generate a timing advance based on the path length, the time reference, and the time slot. The satellite may begin to receive the UL packets within the time window and may search received signals over the time window to identify the UL packets. The satellite may recover data payloads from the identified UL packets and may pass the recovered data payloads up a protocol stack. By limiting the search to the time window, the satellite may correctly distinguish the UL packets while using a minimal amount of processing resources.

One or more echo dominant audio signals can be determined based on a pick-up beam directed towards one or more speakers of a playback device. Sound that is emitted from the one or more speakers and sensed by the plurality of microphones can be removed from plurality of microphone signals, by using the one or more echo dominant audio signals as a reference, resulting in clean audio.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.
