Patent ID: 8558802

Claim:
A method for performing capacitive touch sensing and proximity detection, the method comprising the steps of: storing an individual electrode baseline value for each individual electrode of a plurality of individual electrodes; storing one proximity electrode baseline value for a proximity electrode that comprises multiples ones of the plurality of individual electrodes; establishing a first connection with an individual electrode of the plurality of individual electrodes in order to receive one or more first signals indicating a state of the individual electrode; performing a first analysis of the one or more first signals to determine whether to perform a first updating process for the individual electrode baseline value previously stored for the individual electrode; establishing simultaneous second connections with the multiple ones of the plurality of individual electrodes that form the proximity electrode in order to receive one or more second signals indicating a state of the proximity electrode; and performing a second analysis of the one or more second signals to determine whether to perform a second updating process for the proximity electrode baseline value previously stored for the proximity electrode, wherein the first analysis and the second analysis are different from each other.
