(under subclass 439) Subject matter in which the coded indicia on the record is sensed by more than one complete sensing structure.
(1) Note. Each sensing structure may include an array of or
multiple sensing elements.
(2) Note. Classification is not proper here if one of two sensing structures is that which senses timing marks.
(3) Note. The sensing structures may be used to simultaneously sense separate areas of the record or to sense the same areas at different points in time.
(4) Note. The sensing structure may include diverse types.
