  • CURVED PROFILE TOUCH SENSOR SYSTEMS AND METHODS
    Publication number: 20140104196
    Abstract: Systems and related methods providing for touch sensors having at least one non-linear edge. A touch sensor may include a substrate configured to propagate surface acoustic waves. The substrate may include a front surface, a back surface including a reflective array, and a connecting surface joining the front surface and the back surface. The front surface may define a front bowed edge and the back surface may define a back bowed edge. The connecting surface may be between the front bowed edge and the back bowed edge. The reflective array may be configured to cause the surface acoustic waves to propagate from the back surface, is the connecting surface, to the front surface. The touch system may further include circuitry configured to determine a coordinate of a touch event on the front surface based on received attenuations in the surface acoustic waves.

  • Method and apparatus for detecting hold condition on an acoustic touch surface
    Patent number: 8659579
    Abstract: 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.
