Patent ID: 8358809

Claim:
A pattern recognizer comprising: a) a sequential data extractor configured to: i) extract a region of measured data from measured data, the measured data obtained using a measuring device, the measuring device capable of detecting changes in impedance; and ii) processing the region of measured data to determine discrete position information of the individual changes in impedance; b) a data pairer configured to: i) receive the processed region of measured data from the sequential data extractor; ii) receive a priori pattern data, the a priori pattern data containing expected positions of the individual changes in impedance; iii) associate the processed region of measured data and the a priori pattern data; c) a programmable recognition engine device having a decision output, the decision output configured to indicate whether the associated processed region of measured data and the a priori pattern data differ within predetermined criteria, the predetermined criteria including: i) non-expected impedance changes; ii) excessive dither; and iii) missing impedance changes; and wherein the recognition engine is a serial major-minor reset finite state machine.
