Abstract: A processing system (and associated input device and method) is disclosed that includes a display module configured to drive a display signal onto a plurality of sensor electrodes for updating a display, and a sensor module configured to communicate with the plurality of sensor electrodes. The sensor module is configured to, in a first mode of operation, operate the plurality of sensor electrodes to receive an active input from an active input device, and in a second mode of operation, operate the plurality of sensor electrodes to receive capacitive sensing data from a passive input device. The processing system further includes a determination module configured to determine a position of the active input device based on a harmonic of the active input signal.

Abstract: Embodiments of the invention generally provide a touch sensing device that is integrated with one or more components that are configured to use a wireless communication technique, such as a near field communication (NFC) technique, to communicate with another wireless communication enabled device. Some embodiments of the invention include configurations in which the touch sensing components and one or more NFC enabling components are configured so that the close proximate positioning of these components will minimally affect each other's performance during normal operation. Embodiments of the invention may also provide an integrated touch sensing electrode design and wireless communication coil design that has a reduced system complexity, small overall physical size, low production cost and reduced electrical interaction.

Abstract: In a method of active pen signal detection, a signal is received from an active pen, wherein the active pen is configured for use with a capacitive sensing input device. At least one of downconverting and aliasing is performed on the signal to achieve a resulting signal. Presence of one of a plurality of possible resulting signal frequencies present in the resulting signal is detected. The detected resulting signal frequency is associated with a particular one of a plurality of possible transmission frequencies of the signal, and each of the plurality of transmission frequencies of the signal represents information about operation of the active pen.

Abstract: Embodiments described herein include an input device with a plurality of sensor electrodes, where each sensor electrode includes at least one display electrode of a plurality of display electrodes, and where each display electrode is configured to be driven for display updating and capacitive sensing. The input device also includes a processing system configured to acquire sensor data using one or more sensor electrodes during one or more display blanking periods, where a first half sensing period occurs during a first display blanking period and a second half sensing period occurs during a second display blanking period. The processing system acquires sensor data using a first resulting signal from the first half sensing period and a second resulting signal from the second half sensing period.
