Abstract: 3M468 3M-467MP QUANTUM CAPACITIVE Qmatrix membrane key AN-KD01 3M-467 xy capacitor 3M Touch Systems
Contextual Info: QUANTUM RESEARCH APPLICATION NOTE AN-KD01 QMatrix Panel Design Guidelines Applies to all 16 key+ QT60xxx QMatrix™ ICs 10 October 2002 Quantum's QMatrix™ controllers use sequentially scanned transverse electrodes composed of two parts; this differs markedly when compared with the single-ended electrodes used with QT1xx and QT3xx devices.

ATMEL touch controller IC
Abstract: Qmatrix QAN0015 QUANTUM CAPACITIVE ANKD01 QT2160 QTAN0030 Example capacitive touch slider AN-KD01 CHARGE-TRANSFER TOUCH SENSOR
Contextual Info: QTAN0030 Implementing a Long Slide Control Using a QMatrix IC QMatrix ICs such as the QT2160 can be used to produce very effective slider controls by merging the touch signals from a number of closely spaced keys. The basic technique will produce controls of up to 60 mm in length, but special interpolation
