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 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.

International Classification:

US Classification:

23546201, 23546225, 23546244

Abstract:

Disclosed is an automatically-activated body-wearable code symbol reading system comprising a bar code symbol reading mechanism contained within a body-wearable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e. g. product, bar code menu, etc. ) so that the bar code symbol is scanned, detected and decoded in a cyclical manner.

Abstract:

Disclosed is an automatically-activated code symbol reading system comprising a code symbol reading mechanism contained within a hand-supportable housing having a manually-actuatable data transmission switch. The symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more code symbols on an object during each symbol reading cycle, and automatically generating a new symbol character data string in response to each read symbol. The user visually aligns the laser scanning pattern with a code symbol on an object. Each time the scanned symbol is successfully read in a cyclical manner, a new symbol character string is produced, and an indicator light is actively driven. During the symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a subsequently produced symbol character data string to be automatically selected and transmitted to the host system.
