Abstract: A touch sensing system may include a pressure and force sensing device capable of sensing dynamic pressure or dynamic force applied to a piezoelectric sensing array. In such implementations, an applied force may be detected (and optionally recorded) during a period of time that the force is applied and changing. The force-sensing device may have a sufficiently high resolution to function as a fingerprint sensor. The touch sensing system may include one or more additional components capable of fingerprint sensing, such as an ultrasonic transmitter that allows the device to become an ultrasonic transducer capable of imaging a finger (or another object) in detail. The force-sensing device also may be capable of functioning as an ultrasonic receiver.

Abstract: A computer control system and a method of controlling a computer are disclosed. One such system includes an area-array sensor and a processor. The processor may have a navigation mode, and when set to this mode, the processor is configured to execute certain tasks. Those tasks may include acquiring a first information set and acquiring a second information set from the sensor.
