Patent
Varying demodulation to avoid interference
TL;DR: In this article, a shift from using the first demodulated output for determining positional information to using the second demodulation for determining the positional information is made based at least in part upon an amount of interference.
Patent
Input device for touch sensitive devices
TL;DR: In this article, a method for receiving data from an input device to a computing device through a touch interface is proposed, which includes detecting an input devices, synchronizing with the input device by receiving a position signal and activating an input-device scan of the touch interface, receiving a data signal from the input devices through at least one of a sense line or a drive line of the input interface, and scanning the touch interfaces for a touch input by applying a stimulation signal to the at most one drive line and analyzing the at least 1 sense line.

TL;DR: In this article, the authors present a method for wireless sensor data transmission from one or more sensors in or on a stylus to a device through a touch sensor of the device.
Patent
Touch controller architecture
TL;DR: In this paper, a touch controller that can configure touch circuitry according to a scan plan, which can define a sequence of scan events to be performed on a touch panel, is presented, which advantageously provides more robust and flexible touch circuitry to handle various types of touch events at the panel.
Patent
Sensing during non-display update time to avoid interference
TL;DR: In this article, a transmitter signal is transmitted with a combination electrode of the integrated capacitive sensor device and display device during a non-display update time period associated with row update of the display device.
