Abstract
In one embodiment, an apparatus includes a sensor having a plurality of electrodes and a controller having a processor and a memory. The memory includes logic operable, when executed by the processor, to connect each electrode of a first subset of the plurality of electrodes, apply voltage to the first subset, and determine a first value associated with a capacitance of the first subset. Based at least on the first value, the logic is further operable to connect each electrode of a second subset of the plurality of electrodes, the second subset having fewer electrodes than the first subset, apply voltage to the second subset, and determine a second value associated with a capacitance of the second subset.
