Abstract
A pattern recognizer includes a sequential data extractor, a data pairer, and a recognition engine. The sequential data extractor extracts a region of measured data obtained from a measuring device. The measuring device is preferably capable of detecting changes in impedance. The measured data should contain position information of the changes in impedance. The data pairer associates the region of measured data with a priori pattern data that contains expected positions of the changes in impedance. The recognition engine decides whether the associated region of measured data and the a priori pattern data differ within predetermined criteria, the predetermined criteria including: non-expected impedance changes; excessive dither; and missing impedance changes.
