Abstract: A pen configured for use with a touch sensor includes a pen tip that is configured to make contact with the touch sensor. The pen body includes an electrically conductive receiver portion and an electrically conductive emitter portion that is electrically insulated and electrostatically shielded from the receiver portion. The pen includes circuitry configured to receive a touch sensor drive signal applied to a drive electrode of the touch sensor through the receiver portion of the pen body. In response to the received signal, the pen circuitry generates a pen drive signal that is phase additive with the touch sensor drive signal and emits the pen drive signal through the emitter portion of the pen body.

Abstract: A touch-sensitive apparatus includes a touch panel comprising a touch sensitive surface and at least one a drive electrode capacitively coupled to at least one receive electrode. A sense circuit generates a response signal for the receive electrode in response to a drive signal delivered to the drive electrode. A measurement circuit applies a time-varying transfer function to the response signal. The transfer function varies proportionately and synchronously with the response signal. A calibration circuit is used to match the time-varying transfer function to the response signal.

Abstract: A touch sensitive system includes a touch sensitive area. A plurality of spaced apart first electrodes are disposed in the touch sensitive area and extend continuously along a first direction. A plurality of spaced apart second electrodes are disposed in the touch sensitive area and extend continuously along a different second direction. A plurality of nodes are disposed in the touch sensitive area, each node being defined by corresponding first and second electrodes traversing each other at the node. The touch sensitive system detect a location of a touch applied proximate a node by detecting a change in a coupling capacitance between the corresponding first and second electrodes traversing each other at the node. Each first electrode traverses at least one, but not all, of the second electrodes, and each second electrode traverses at least one, but not all, of the first electrodes.

Abstract: A touch-sensitive device that includes a touch surface circuit that facilitates a change in a coupling capacitance in response to a capacitance-altering touches occurring at the touch surface. The device includes a sense circuit that provides a signal, in response thereto, having transient portions for characterizing positive-going transitions towards an upper signal level and negative-going transitions towards a lower signal level. An amplification circuit is then used for amplifying and processing the signals, in response to the time-varying input parameters. The amplification circuit adjusts the gain for the transient portions relative to gain for portions of the response signals between the transient portions, and thereby suppresses RF interference, such as in the form of signal odd and/or even harmonics, to provide a noise filtered output for determining positions of capacitance-altering touches on the touch surface.
