摘要:
Capacitive detection systems, modules, and methods. In one embodiment, time interval measurement(s) are generated that are monotonic functions of the capacitance(s) of capacitive sensor(s) in a capacitive sensing area. In one embodiment, the generated time interval measurement(s), or any other monotonic function(s) of capacitance(s) of capacitive sensor(s) in a capacitive sensing area, may be analyzed to detect the presence of an object near the capacitive sensing area and/or to detect the position of an object near the capacitive sensing area.
