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 ...

Chinh Tan, Paul Dvorkis, Ron Goldman, Narayan Nambudiri, Carl Wittenberg, Miklos Stern, Dmitriy Yavid, Frederick F Wood: Method and apparatus for capturing images using a color laser projection display. Symbol Technologies, Kirschstein et al, November 27, 2007: US07302174 (47 worldwide citation)

A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a pict ...
