Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

Abstract: A mobile computing device is configured to dynamically aggregate wireless communications on a common antenna. The device determines that a WiFi communication in a first frequency band is associated with an antenna, the WiFi communication having a number of assigned transmission time slots. The device determines that a second wireless communication in a second frequency band also is associated with the antenna, and determines a periodicity and/or a media quality of the second wireless communication. Based on the periodicity and/or media quality of the second wireless communication, the device aggregates the WiFi communication and the second wireless communication, the aggregation comprising assigning a number of packets of the second wireless communication to an aggregation frame of a plurality of frames associated with the transmission time slots assigned to the WiFi communication.

Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, using a shared antenna, e.g., due to limitations resulting from a small form factor of the wireless communication device. The wireless communication device may determine whether communications according to a second protocol are causing performance of communications according to a first protocol to fall below a threshold level. If so, the wireless communication device may operate in a mode that favors communications according to the first protocol. If not, the wireless communication device may operate in a mode that favors communications according to the second protocol. For example, the mode that favors communications according to the first protocol may include temporarily implementing operations to remedy the poor performance of the communications according to the first, e.g., periodically, until the performance of the communications according to the first protocol recovers.

Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, by dynamically adjusting priority between the two protocols. The wireless communication device may typically favor a first protocol (e.g. Bluetooth/BTLE), prioritizing resource requests by the first protocol. In certain use cases, the first protocol may demand high resource usage for an extended time, particularly for newer tracking and wearable devices, such as location tags, watches, headsets, etc. Such applications can disrupt existing use cases for a second protocol (e.g., Wi-Fi). Therefore, the wireless communication device may dynamically determine whether the second protocol is performing critical operations, such as latency-sensitive applications or high-performance operations. If so, the wireless communication device may allocate resources accordingly in real time, e.g., by reducing or limiting the resources assigned to the first protocol, to allow increased resources for the second protocol.
