  • Patent number: 7743667
    Abstract: A capacitive device and method with an enhanced measurement error correction capability is disclosed. In one embodiment, an apparatus includes a sensor capacitor based on one or more pairs of parallel conductor surfaces, a housing to encompass the sensor capacitor, a digitizer module in the housing to generate a digital measurement based on a change in a capacitance of the sensor capacitor when a contact zone of the housing is deflected by a force applied on the contact zone. The apparatus also includes a compensation module of the digitizer module to apply another digital measurement of one or more distortion factors to the digital measurement to minimize an effect of the one or more distortion factors to the apparatus. In addition, the apparatus includes a communication module to communicate an analog signal and/or a digital signal through a wired channel and/or a wireless channel.
