Abstract
Apparatuses and methods for coupling a group of sensor elements together in one mode to collectively measure a capacitance on the group of sensor elements, in addition to individually measuring a capacitance on each of the sensor elements in another mode. The apparatus may include a processing device, and a plurality of sensor elements that are individually coupled in a first mode for normal sensing and collectively coupled in a second mode for proximity sensing.
