1. 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.
