Patent ID: 8508504

Claim:
A method comprising: (a) performing, while a touch panel is being touched, a series of scans of the touch panel at a single frequency, with each scan yielding a scan value; (b) comparing the scan values of the series to each other to find a set of scan values that are close to each other in that they differ from each other by less than a threshold; (c) if the set of close scan values are found, then setting a final scan value to an average of the close scan values; (d) repeating steps (a)-(c) at the same single frequency until (i) the set of close scan values are found within a single series, or (ii) steps (a)-(c) have been performed a predetermined number of times, whichever occurs first; and (e) if steps (a)-(d) have been performed the predetermined number times without the set of close scan values being found within a single series, then repeating steps (a)-(d) with a different frequency.
