摘要： Embodiments of the invention generally provide a method and system that is able to minimize or remove the affect of substantially non-random electrical interference on an input device's ability to reliably and accurately sense the position of an object. In one embodiment, the input device is configured to systematically correct for a cyclic variation in the electromagnetic interference (EMI) generated by components within the electronic system, such as interference generated by the process of refreshing or updating an image on a display module that affects the capacitive sensing measurements acquired from a plurality of capacitive sensing elements. However, in some embodiments of the invention, the performance of an input device is improved by reducing the affect that external interference generated outside of the electronic system have on the position sensing data acquired by the input device.

摘要： A method and system are provided that reduce the effect of substantially non-random electrical interference on an input device's ability to reliably and accurately sense the position of an object. Several embodiments improve performance of an input device by reducing the effect of interference on position sensing data acquired by the input device. In one embodiment, the input device corrects for a cyclic variation in the electromagnetic interference (EMI) generated by components within the electronic system, such as interference from refreshing or updating an image on a display module that affects the capacitive sensing measurements acquired from a plurality of capacitive sensing elements. However, in some embodiments, performance of an input device is improved by reducing the effect that external interference generated outside of the electronic system has on the position sensing data acquired by the input device.

摘要： The embodiments described herein provide devices and methods that facilitate improved performance. In one embodiment, an input device comprises a processing system, a transmitter sensor electrode, and a receiver sensor electrode, where the transmitter sensor electrode and the receiver sensor electrode are capacitively coupled. The processing system is configured to receive a resulting signal from the receiver sensor electrode, where the resulting signal includes responses that correspond to the transmitter signal. The processing system is further configured to separately accumulate, for each cycle of the transmitter waveform, a first portion and a second portion of the resulting signal to respectively produce a first accumulation and a second accumulation, wherein the first accumulation is used for determining user input to the input device and the second accumulation is used for determining interference, and wherein the first portion and the second portion are non-coterminous.
