摘要： A bending wave touch system includes at least one sensor and a touchscreen controller. The at least one sensor is coupled to a substrate and is responsive to vibrations in the substrate. The at least one sensor outputs signals. The controller receives the signals from the at least one sensor and identifies touch coordinates based on high frequency components of the signals when a touch on the substrate includes at least one of a tap, a drag and a lift-off. The controller identifies a status of a hold condition of the touch based on at least two different time averages of low frequency components of the signals.

摘要： Resistive touchscreen system has substrate and coversheet with first and second conductive coatings. The substrate and coversheet are positioned proximate each other such that the first conductive coating faces the second conductive coating. The substrate and coversheet are electrically disconnected with respect to each other in the absence of a touch. First set of electrodes is formed on the substrate for establishing voltage gradients in first direction. Second set of electrodes is formed on the coversheet for establishing voltage gradients in second direction wherein the first and second directions are different. Controller biases the first and second sets of electrodes in first and second cycles and senses a bias load resistance associated with at least one of the sets of electrodes. The bias load resistance has a reference value associated with no touch. A decrease in the bias load resistance relative to the reference value indicates two simultaneous touches.

摘要： A touch sensor device, and its method of operation, that provides information as to the position of a touch thereon together with information as to the amount of pressure applied to the sensor at the touch position. The device has a pair of spaced-apart membranous sheets with coatings thereon suitable for the determination of position information in a conventional manner. In addition, switching units are included which, during a given time interval of operation, supply a uniform electrical potential in one of the sheets. During that same interval contacts or electrodes on opposite edges of the second sheet are rapidly switched to alternately be oppositely connected to ground on one edge and to the information processing unit at the other edge. In this manner, there is a fixed potential applied to the contact resistance circuit created between the sheets due to the touch pressure, and the alternate switching averages the potential on the second sheet. As a result, the pressure information is substantially independent of the position of touch on the sensor.
