Abstract:
In one embodiment, the present invention receives sensitivity data corresponding to a plurality of first sensor channels of a respective plurality of capacitive sensing devices and utilizes the sensitivity data to determine a range of expected variation pertaining to the plurality of first sensor channels. The range of expected variation has an upper and a lower limit. The present embodiment also relates the range of expected variation to a sensitivity value corresponding to one of the plurality of first sensor channels. The present embodiment determines at least one performance characteristic of the one of the plurality of first sensor channels near at least one of the upper limit and the lower limit. In this embodiment, the at least one performance characteristic enables the tuning of the plurality of first sensor channels of the respective plurality of capacitive sensing devices.
