System And Method For Using Signals Resulting From Signal Transmission In A Touch Sensor

A system comprising:

• a first line of electrodes arranged along a first axis;
• a first track coupled to the first line of electrodes and electrically coupled to a controller, the impedance of the first track less than the impedance of the first line of electrodes;
• a second line of electrodes arranged along the first axis and spaced apart from the first line of electrodes along a second axis;
• a second track coupled to the second line of electrodes and electrically coupled to the controller, the impedance of the second track less than the impedance of the second line of electrodes, the ratio of impedances of the second track to the second line of electrodes being substantially equal to the ratio of impedances of first track to the first line of electrodes;
• a third line of electrodes arranged along the first axis and spaced apart from the second line of electrodes along the second axis;
• and
• a third track coupled to the third line of electrodes and electrically coupled to the controller, the impedance of the third track less than the impedance of the third line of electrodes, the ratio of impedances of the second track to the second line of electrodes being substantially equal to the ratio of impedances of third track to the third line of electrodes.

A method comprising:

• sending, by a controller coupled to a first set of electrodes, a first set of signals through a transmission medium to the first set of electrodes, the first set of electrodes substantially arranged along a first axis, an impedance of the transmission medium different than an impedance of the first set of electrodes;
• receiving, by a controller, a second set of signals, the second set of signals comprising characteristics resulting from effects on the first set of signals from the first set of electrodes and the transmission medium;
• changing, by the controller and in response to analyzing the second set of signals, one or more of the following:
• an impedance of the controller and a voltage associated with the controller.
