1. A touch sensitive device, comprising:
- a touch sensor system having a touch sensitive surface that senses contact made by an object to or proximate to the touch sensitive surface and that generates touch signals indicative of the contact sensed by the touch sensor system;
a vibration sensor system that senses vibrations that occur when the contact is made by the object to the touch sensitive surface and that senses vibrations that are not associated with the contact and that generates vibration signals indicative of the vibrations sensed by the vibration sensor system;
a sensor data memory; and
at least one controller adapted to receive the vibration signals and to cause vibration data indicative of particular vibrations sensed during each of a plurality of sample periods to be stored in a vibration data in the sensor data memory, wherein the controller is further adapted to receive the touch signals and to cause touch data to be stored in the sensor data memory in temporal association with the vibration data record, wherein the at least one controller provides a first portion of the vibration record data that is in temporal association with the touch data for the contact to a processor, and wherein the at least one controller does not provide a second portion of the vibration data that is not in temporal association with the touch data for the contact to the processor so that the second portion of the vibration data corresponds to vibrations that are not associated with the contact.

Abstract
Touch sensitive devices having sensor systems and sensor systems for use with touch sensitive devices are provided. A vibration sensor senses vibrations and a touch sensor senses contact with an object. Vibration data representing sensed vibration is stored in a sensor data memory and touch data indicative of contact between the object and the touch sensitive surface is stored in the sensor data memory in temporal association with the vibration data. The touch data and the temporal association with vibration data can be used to identify segments of the vibration data that are of interest.

17. A sensor system for use in a touch sensitive device, comprising:
-
a first sensor adapted to sense a first physical condition experienced at the touch sensitive device and to generate a first sensor signal, the first physical condition associated with when a contact is made by an object proximate to or in direct contact with the touch sensitive surface and that generates the first sensor signal; and a sensor driver adapted to receive the first sensor signal and store first sensor data in a sensor data memory representing conditions, including the first physical condition, sensed during each of a sequence of sample periods and further adapted to receive a vibration signal indicative of a plurality of conditions, including the first physical condition and a second physical condition experienced at the touch sensitive device, and to store second sensor data for the vibration signal in the sensor data memory in temporal association with the first sensor data, wherein the second physical condition is independent of the first physical condition; wherein the sensor driver is adapted to provide a first portion of the first sensor data and the second sensor data that are temporally associated together in association with the first physical condition to a processor, and wherein the sensor driver is adapted to not provide a second portion of the first sensor data and the second sensor data that are temporally associated together in association with the second physical condition to a processor. - View Dependent Claims (18, 19)
