    摘要： A system and method for reducing the number of electrodes needed to operate a touch sensor by arrangement of drive and sense electrodes on a single layer touch sensor, the electrodes being arranged such that drive signals that are sent to the electrodes are sent in a non-uniform pattern that enables selected regions of the touch sensor to generate a useful drive signal while the remaining regions do not. The arrangement of the drive and sense electrodes is such that the routing of signals to and from the electrodes may not interfere with operation of the touch sensor.

    摘要： A touch sensor having a plurality of parallel drive electrodes that are being electrically driven, providing stimulus on one end or simultaneously on both ends, thus creating a linear or varying electric field across the length of the drive electrodes, wherein adjacent sensor electrodes are connected to a sense amplifier and analog-to-digital (ADC) converter to determine the position of an object that comes near to the drive and/or sense electrodes, wherein the system uses self-capacitance and measures the amount of current driven by each driver, wherein the system uses a mutual capacitance current divider in a first method by driving an electrode with a time varying voltage and measuring induced currents at each end of an adjacent sense electrode and using ratiometric equations to determine finger position, and using a mutual capacitance voltage divider in a second method.

    摘要： A system and method for balancing the capacitive charge on touch sensor electrodes so that every two adjacent routes have the same capacitance as any other adjacent two routes, wherein routing electrodes are spaced further and further apart, or graduated, as they get longer, to thereby balance the capacitance on the touch sensor electrodes without having to add or subtract an offset from each touch sensor electrode.

    摘要： Capacitive sensing electrodes may be placed in strategic locations inside, outside or inside and outside of a card reader, wherein touch sensor circuitry is then used to take mutual capacitance or self-capacitance measurements that are saved in non-volatile memory as a reference intrusion measurement that is not deleted when power is removed, wherein the reference intrusion measurement may then be used during subsequent intrusion measurements to determine if a skimming device has been disposed adjacent to the card reader, and if a skimming device is detected, appropriate action may be taken such as the automatic disabling of the card reader, the display of a message indicating that the card reader should not be used, or any other action that may prevent a financial card from being compromised.
