  • Touch panel using acoustic wave reflection
    Patent number: 6078315
    Abstract: A touch position sensor is shown in which a transducer or transducer array mounted to a side of a substrate generates pulse shear-mode acoustic wave and receives the partial wave reflected by the finger or other styles. An electronic circuitry connected to the transducers determine the position of the finger or style in geometrical coordinate terms by detecting time interval between the transmitted wave and reflected wave.
