| 1. A method of automatically adjusting gain when scanning an array of pressure or force responsive sensor elements, the method
comprising:
(A) detecting a frame of received signals corresponding to a plurality of sensor elements of the array being scanned;
(B) determining a signal strength value at least partially based on the frame of received signals, the signal strength value
comprising a count of a number of the received signals of the frame that are greater than a threshold signal value; and
(C) adjusting a gain applied to at least some signals received from the array based at least partially on the signal strength
value.
