Paintbrush stylus for capacitive touch sensor pad
TLDR
In this paper, a touch-sensor pad with a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads is used to produce paint-like strokes on a display associated with the touch sensor pad.Abstract:
A proximity sensor system includes a touch-sensor pad with a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed. A conductive paintbrush-type stylus is used to produce paint-like strokes on a display associated with the touch-sensor pad.read more

Stylus switch status determination in a digitizer tablet having a cordless stylus
TL;DR: In this article, the relative ratio of the signal frequency outputs of the oscillators can be varied in response to activation of a switch while at the same time the sum of the amplitudes of oscillating signals remain constant, which can be used as an indication of the position of the pointing device with respect to the tablet.
