Abstract:
Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

Claim (Index 9):
The device of  claim 1 , wherein determining the location of the contact by the object on the surface comprises:\n determining a first time-of-flight of an ultrasonic wave propagating between a first edge the surface and a first leading edge of the object proximate to the first edge; determining a second time-of-flight of an ultrasonic wave propagating between a second edge the surface and a second leading edge of the object proximate to the second edge; determining a third time-of-flight of an ultrasonic wave propagating between a third edge the surface and a third leading edge of the object proximate to the third edge; and determining a fourth time-of-flight of an ultrasonic wave propagating between a fourth edge the surface and a fourth leading edge of the object proximate to the fourth edge.
