Claim 13:
14. A system comprising:
a substrate:
a set of sense electrodes arranged on the substrate;
a set of drive electrodes arranged proximal the set of sense electrodes to form an array of drive and sense electrode pairs;
a controller configured to:
at a first time, read a first sense signal from a first drive and sense electrode pair, in the array of drive and sense electrode pairs, the first sense signal characterized by a first alternating component and a first direct component;
in response to a first magnitude of the first direct component of the first sense signal falling below a threshold magnitude, detect a first input at a first location proximal the first drive and sense electrode pair based on the first alternating component of the first sense signal;
at a second time, read a second sense signal from a second drive and sense electrode pair, in the array of drive and sense electrode pairs, the second sense signal characterized by a second direct component; and
in response to a second magnitude of the second direct component exceeding the threshold magnitude, detect a second input at a second location proximal the second drive and sense electrode pair based on the second direct component of the second sense signal.
