Abstract: An electrode for a touch sensitive device includes micro-wire conductors arranged to define an electrically continuous area and to include interior regions that are electrically discontinuous. The electrically continuous area may be patterned according to a one pattern, and the interior pattern may be patterned according to another pattern.

Abstract: An approach for determining touch location on a touch panel includes receiving information indicative of which of the electrodes in the first set of electrodes are not experiencing, or are unlikely to experience, a touch is received. Based on the received information, at least one electrode is selected from the first set of electrodes to function as a first reference electrode, remaining ones of the first set of electrodes referred to as first remaining electrode. Touch signals are measured for at least some of the touch panel nodes using a differential technique. The differential technique for each such node utilizes the first reference electrode in combination with at least one of the first remaining electrodes and with at least one of the electrodes from the second set of electrodes.

Abstract: A digitizer system includes a substrate with indicia that uniquely define local areas of the substrate. A multi-mode sensor device, such as a stylus, may sense radiation emitted from the features, and selectively switch to a mode of operation that can sense the indicia and determine therefrom the location of the stylus relative to the substrate.

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.
