Abstract:
1. A method for enabling the tuning of a capacitive sensing device, said method comprising: receiving sensitivity data corresponding to a plurality of first sensor channels of a respective plurality of capacitive sensing devices; receiving a range of expected variation pertaining to said plurality of first sensor channels, said range of expected variation pertaining to said plurality of first sensor channels having an upper limit and a lower limit; relating said range of expected variation pertaining to said plurality of first sensor channels to a sensitivity value corresponding to one of said plurality of first sensor channels; and determining at least one performance characteristic of said one of said plurality of first sensor channels near at least one of said upper limit and said lower limit of said range of expected variation pertaining to said plurality of first sensor channels, said at least one performance characteristic enabling the tuning of said plurality of first sensor channels of said respective plurality of capacitive sensing devices.
