Abstract: Systems, methods, and computer-readable media are disclosed for streaming media content. The systems, methods, and computer-readable media described herein may improve user experiences and reduce device failures by mitigating problems between devices. In an example method described herein, a media streaming device may be connected to a display device in order to facilitate streaming of content. A processing apparatus of the media streaming device may determine that the display device is not presenting content streamed from the media streaming device and in turn switch the antenna radiation pattern from a first pattern to a second pattern.

Abstract: Embodiments of the subject technology provide for controlling desense in a mobile computing device. At an application processor of a mobile computing device, a drive strength of an input clock signal is increased. The input clock signal with the increased drive strength is then provided to a filter circuit that performs low-pass filtering to block high frequency RF and EMI noise from the input clock signal. The filtered input clock signal is provided to respective camera clock units of a front-facing camera or a rear-facing camera of the mobile computing device for operating the front-facing and rear-facing cameras.

Abstract: Techniques are described for dynamically tuning mobile device antennas. Input derived from multiple sources and representing a variety of scenarios is provided to the RF modem of a mobile device. The modem is configured to select antenna tuning settings based on this input, each of which tunes the antenna by modifying its impedance as appropriate for the corresponding scenario.

Abstract: Embodiments of the subject technology provides a novel approach to address desense and provide electrostatic discharge (ESD) protection among components for a collocated antenna and speaker configuration in a mobile computing device. The available metal around the periphery of speaker components are used as part of implementing an antenna(s) and also for tuning the antenna, which results in an efficient antenna design that can be implemented within an available (relatively small) area of a PCB and also without adding components, which could further increase the overall cost of the mobile computing device. An inductor is used to isolate the antenna away from a ground to mitigate desense for the antenna. The inductor is connected to a diode and capacitor in series. The diode provides ESD protection for the speaker. The capacitor is connected to the diode in parallel to shunt nonlinearities generated by the diode to ground.
