| 20100006350 | Stylus Adapted For Low Resolution Touch Sensor Panels - Methods and apparatus adapted to ensure that contact from a stylus will be detected on a low resolution touch sensor panel irrespective of the location of the region of contact upon the touch surface. In some embodiments, a metallic or otherwise conductive disk may be attached to one end of the stylus. The disk may be sized so as to guarantee sufficient electrical interaction with at least one sensory element of the touch sensor panel. In some embodiments, the stylus may be powered so as to provide a stimulus signal to the capacitive elements. Optionally, one or more force and/or angle sensors disposed within the stylus can supply additional data to the touch panel. | 01-14-2010 |
| 20100013800 | Capacitive Sensor Coupling Correction - Methods and apparatus for normalizing the effects of the changes to the parasitic capacitive coupling that can occur in touch sensor panels so as to reduce or eliminate the appearance of erroneous touch events. In some embodiments, at some time prior to regular device use (e.g. during factory calibration), a conductive sheet is initially positioned so as to entirely cover a touch surface of a touch sensor panel. A set of sensed signals may be determined upon driving the drive lines and sensing the sense lines of the panel. Correctional coefficients may then be calculated based in part upon the difference between a sensed signal and an expected signal. The correctional coefficients may then be stored in the device and used to determine signal corrections for a set of measured signals during normal operation. | 01-21-2010 |
