A projected capacitive touch sensor system includes a substrate that defines a plurality of non-overlapping areas. Each non-overlapping area includes a plurality of detection electrodes arranged in non-overlapping columns. The columns include a horizontal detection electrode that extends along substantially an entire height of a first column, and at least a second column of at least two vertical detection electrodes that are electrically isolated from one another. The system further includes a measuring circuit configured to measure a mutual capacitance between the horizontal detection electrode and each of the at least two vertical detection electrodes in a given area. A processing logic circuit of the system is configured to determine horizontal detection electrode and vertical detection electrode combinations that have a changed mutual capacitance. The processing logic is also configured to determine the touch location based on a location of the determined horizontal detection electrode and vertical electrode combinations.

System and method for detecting locations of touches on a touch sensor

A touch input system includes a substrate configured to support propagation of acoustic signals, a transducer in communication with the substrate and configured to transmit or receive the acoustic signals before or after the propagation, and an array of reflectors disposed on the substrate. Each reflector is oriented on an angle to redirect the acoustic signals along a path toward or away from the transducer. The transducer includes a stepped interface for the redirected acoustic signals. The stepped interface includes a set of interface elements distributed across a width of the acoustic signals and offset from one another along the path to compensate for the angle of the reflectors.
