    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: Touch location determination approaches involving a plurality of touch location techniques are described. Each touch location technique is capable of independently determining a location of a touch within a touch area of the touch sensitive device. The touch location determination made by at least one touch location technique is enhanced using touch location information associated with the touch acquired from one or more other touch location techniques. One touch location technique may use a different type of sensor, signal, and/or algorithm from the one or more other touch location techniques.

    Abstract translation: 描述涉及多个触摸定位技术的触摸位置确定方法。 每个触摸定位技术能够独立地确定触摸敏感设备的触摸区域内的触摸的位置。 使用与从一个或多个其他触摸位置技术获取的触摸相关联的触摸位置信息来增强由至少一个触摸位置技术进行的触摸位置确定。 一触式定位技术可以使用来自一个或多个其它触摸定位技术的不同类型的传感器，信号和/或算法。
