摘要

Apparatus for simultaneously comparing a given signal with a plurality of reference signals to determine if the given signal matches a reference signal of the plurality of reference signals comprising: an optical pattern detector for each reference signal of the plurality of reference signals that generates an output signal when illuminated by a predetermined light pattern uniquely associated with the reference signal; and an optical pattern generator that generates a light pattern unique to the given signal simultaneously on each of the optical pattern detectors.
