Assignee:

Metrologic Instruments, Inc. - Blackwood NJ
International Classification:

G06K 710
US Classification:

23547201, 23546201
Abstract:

A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

US Patent:

6412700, Jul 2, 2002
Filed:

Mar 22, 1999
Appl. No.:

09/273825
Inventors:

Robert Blake - Woodbury Heights NJ
Carl H. Knowles - Moorestown NJ
George B. Rockstein - Audubon NJ
David M. Wilz - Sewell NJ
Assignee:

Metrologic Instruments, Inc. - Blackwood NJ
International Classification:

G06K 710
US Classification:

23547201, 23546201
Abstract:

The invention is a method and apparatus for automatically reading bar code symbols. One aspect of the present invention concerns a method of reading bar code symbols using an automatic hand-holdable bar code symbol reading device. In general, the automatic bar code symbol reading device comprises a hand-holdable housing containing operative elements which provide an object detection field and a scan field each defined external to the housing. The method involves automatically detecting the presence of an object within the object detection field by sensing object sensing energy reflected off the object. In a preferred embodiment, the object sensing energy is IR radiation produced from an object sensing energy source disposed within the housing. In automatic response to the detection of the object within the object detection field, the hand-holdable device detects the presence of a bar code within the scan field using a laser beam produced within the housing. Then, in automatic response to the detection of a bar code in the scan field, the automatic hand-holdable bar code symbol reading device reads the detected bar code in the scan field by producing scan data signals from the detected bar code and thereafter collecting and analyzing the same.

Appl. No.:

09/792239
Inventors:

Carl H. Knowles - Moorestown NJ
George B. Rockstein - Audubon NJ
David M. Wilz - Sewell NJ
David P. Bubnoski - Marlton NJ
Assignee:

Metrologic Instruments, Inc. - Blackwood NJ
International Classification:

G06K 710
US Classification:

23546244, 23546245, 23547201
Abstract:

A portable automatic code symbol reading system having a laser scanning engine that provide hands-free automatic laser scanning capabilities. The automatic code symbol reading system includes a self-contained power supply aboard its housing, and a power-conserving control subsystem for conserving the consumption of electrical power during automatic portable laser scanning operations. The control subsystem of the present invention has a plurality of control centers which control the operation of the system components in accordance with preselected system control operations. Each of the control centers is responsive to control activation signals generated by certain of the system components upon the occurrence of predefined conditions. Certain of the control centers are capable of overriding other control centers to provide diverse control capabilities. These control capabilities facilitate execution of intelligent functions and power consumption measures required during automatic, hands-free code symbol reading operations.
