Filed:

Mar 5, 2001

Appl. No.:

09/801111

Inventors:

Alex Roustaei - La Jolla CA
Wenji Xia - Nepean, CA
Dennis G. Priddy - Clearwater Beach FL

Assignee:

Symagery Microsystems, Inc.

International Classification:

G06K 0710

US Classification:

23547201, 23546225

Abstract:

An improved optical code reading system and method that enhances the ability of a reader to locate a symbol within a field of view and enhances the error-correcting properties of the encoding scheme commonly used in 2D bar codes. The reader offsets the effects of damaged finder patterns and missing symbol perimeters and, thereafter, detects high-level symbol information such as the code type, symbol size, and the number of rows and columns in the symbol. The reader then identifies those missing portions of a damaged symbol and marks each missing data bit location with a predetermined indicator. A decoding algorithm then interprets the missing bit indicator as an error of known location (e. g. , an âerasureâ), thereby nearly doubling the error correcting strength of all bar codes employing the Reed-Solomon error correction scheme.

Filed:

Oct 18, 1999

Appl. No.:

09/420459

Inventors:

Dennis G. Priddy - Bedford NH, US

International Classification:

H04N 5/225
H04L 9/00

US Classification:

3482201, 713186

Abstract:

A system and architecture that supports an integrated imaging module for use between networks and portable communications products. The integrated imaging module contains a lens, memory, an input/output device, and a multi-function semiconductor device, such as a Complementary Metal-Oxide Semiconductor (CMOS). Within the design of the multi-function semiconductor device are the functions of still and full-motion digital imaging, image processing, automatic identification, a secure personal database, biometric attribute identification for access control, personal finance information, wireless communication protocols, general purpose processing, and memory. The module may be incorporated into any portable wireless communication product and used to capture text and image data for incorporation into a wireless transmission to a remote device.

Filed:

Jun 23, 1994

Appl. No.:

8/264789

Inventors:

Dennis G. Priddy - Safety Harbor FL
Robert S. Cymbalski - Clearwater FL

Assignee:

International Data Matrix, Inc. - Clearwater FL

International Classification:

G06K 1906
G06K 710

US Classification:

235494

Abstract:

A machine readable binary code which is dynamically variable in size, format and density of information is provided. The binary code is formed as a matrix having a perimeter and data contained therein. The perimeter is provided with density indicia for indicating the density of data contained within the matrix. The perimeter is also provided with size indicia for indicating the size of the matrix. By utilizing the density indicia and size indicia, a scanning device is able to calculate the size and information density of the binary code.
