Abstract: A capacitive input device includes sensing electrodes configured to form a capacitive coupling with auxiliary device electrodes of an attached auxiliary device. The auxiliary device electrodes transmit data signals to the sensing electrodes via the capacitive coupling. The capacitive input device also includes processing circuitry configured to decode the data signals received via the capacitive coupling to obtain decoded data.

Abstract: A method of capacitive sensing includes obtaining a capacitive touch profile from multiple receiver electrodes disposed in a sensing region of an input device and obtaining an active pen profile, different from the capacitive touch profile, from the multiple receiver electrodes. The method also includes adjusting, using the capacitive touch profile, the active pen profile to obtain a corrected active pen profile and determining a position of an active pen in the sensing region, using the corrected active pen profile.

Abstract: A method is provided. The method comprises: providing, by a control system of an input device, one or more first beacon signals to an input object; based, at least in part, on force data from the input object, detecting, by the control system, noise interference associated with providing at least one of the one or more first beacon signals to the input object; based, at least in part, on detecting the noise interference, altering, by the control system, a timing schedule for providing one or more subsequent beacon signals; and providing, by the control system, the one or more subsequent beacon signals to the input object based, at least in part, on the timing schedule.

Abstract: A processing system configured to detect an input object proximate the processing system. The processing system includes sensor circuitry configured to make a determination, when the processing system is in a low ground mass (LGM) state, that a large object is proximate to sensor electrodes of the processing system. The sensor circuitry is further configured, in response to a determination that a large object is proximate the sensor electrodes while the processing system is in the LGM state, to drive a first group of sensor electrodes with one of an inverted signal or a non-inverted signal and drive a second group of sensor electrodes with a static DC voltage.

Abstract: A system and method for capacitive sensing using an input device are provided. The input device includes a display, a touch sensor and a processing system. The touch sensor has a plurality of transmitter electrodes with a first subset of positive transmitter electrodes driven by a positive sensing signal and a second subset of negative transmitter electrodes driven by a negative sensing signal. Each positive transmitter electrode spatially alternates with a negative transmitter electrode of the second subset of negative transmitter electrodes. The touch sensor includes a plurality of receiver electrodes arranged in differential pairs. Each differential pair includes a positive receiver electrode coupled to at least one of the first subset of positive transmitter electrodes and a negative receiver electrode coupled to at least one of the second subset of negative transmitter electrodes. The processing system transmits the positive sensing signal and the negative sensing signal, and receives a first resulting signal from the positive receiver electrode and a second resulting signal from the negative receiver electrode. The first resulting signal and the second resulting signal are combined to mitigate noise.
