Paul Dvorkis, Edward Barkan, Harold Charych, James Giebel, Stephen Osterweil, Sundeep Kumar, John Barile, Paul R Poloniewicz, Anthony D Biuso, Steven M Chew: Laser scanning system and scanning method for reading bar codes. Symbol Technologies, Finnegan Henderson Farabow Garrett and Dunner L, October 1, 1996: US05561283 (48 worldwide citation)

A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbo ...

A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edge of the symbol, not beyond. The s ...
