Patent
Object position detector with edge motion feature and gesture recognition
TL;DR: In this paper, the authors proposed a method of generating a signal comprising providing a capacitive touch sensor pad including a matrix of X and Y conductors, developing capacitance profiles in one of an X direction and a Y direction from the matrix, and determining an occurrence of a single gesture through an examination of the capacitance profile, the single gesture including an application of at least two objects on the capacitive sensor pad.

TL;DR: In this paper, a capacitive touchpad pointing device was realized using a two-layer printed circuit board as a substrate by suitable use of screen-printed carbon ink patterning, combined with patterning of the solder mask layer on the top (finger) surface.
Patent
Paintbrush stylus for capacitive touch sensor pad
TL;DR: 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.
Patent
Touch pad driven handheld computing device
TL;DR: A handheld computing device comprises a thin enclosure having two opposing major faces as discussed by the authors, where a display screen is disposed on the first one of the major opposing faces of the enclosure and a touch-sensitive object position detector input device is disposed in the second one.
Patent
Stylus input capacitive touchpad sensor
TL;DR: In this paper, a capacitive touch pad comprises a substrate material, such as a PC board type laminate material, having a plurality of first parallel conductive traces running in a first (X) direction disposed on a first face of the substrate, and a second (Y) direction, usually orthogonal to the first direction, disposed on an opposed second face thereof.
