发明名称 Automatically balanced sensing device and method for multiple capacitive sensors
摘要 Disclosed is method for compensating for variation in the capacitance between multiple capacitive sensors. Prior to sensing operations, baseline capacitance values can be acquired for all sensors. A correction factor can be calculated based on such baseline values. During sensing operations (run-time), variations in capacitance from baseline values can be modified by appropriate correction factors. Sensitivity between sensors can thus be made more uniform.
