from the examiner’s rejection of claims 49-61, which
constitute all the claims remaining in the application.
The disclosed invention pertains to a method and
apparatus for reconstructing a bar coded symbol based on a
plurality of separate scanned fragments of the full symbol.
Representative claim 49 is reproduced as follows:
49. An improved scanner of a type having scanning means
for repetitively scanning a code and for providing a scan
signal repetitively corresponding to at least a fragment of
said code; clock means for generating counts; storage means
for repetitively storing said scan signal; and a processor for
combining successive scan signals into an extended scan signal
cluster; the improvement characterized by:
said scan signal comprising a series of stored counts,
each of which corresponds to a transition between code
elements; and
said processor further comprising:
means for comparing stored counts from successive scan
signals;
means for detecting matching portions of compared counts;
means for combining successive counts having matching
portions into the extended scan signal cluster; and
means for decoding said cluster.
The examiner relies on the following reference:
