摘要:
A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel (100) is used to read bar codes on packages (101, 102, 109-116) entering the tunnel, while a package dimension subsystem (3500) 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 (3502) 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.
摘要:
A bar code symbol driven system for accessing information resources from information servers connected to communication networks, including the Internet. The system includes a bar code symbol reader (7a) for reading bar code symbols encoded with information representative of information resources stored in information servers connected to the Internet and supporting the TCP/IP standard. A computing platform (6) is provided for supporting an Internet browser. A telecommunication modem is operably connected to the computing platform in order to establish a two way telecommunication link between the Internet browser and an Internet service provider (ISP) connected to the Internet. In response to reading bar code symbols (8), the Internet browser automatically accesses information resources from Internet information servers (2) using the information encoded in bar code symbols read by the bar code symbol reader (7a).
摘要:
Methods of and systems for illuminating objects using planar laser illumination beams having substantially planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising a plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images.

A novel transaction-enabling method and system (3) are disclosed, wherein a transaction-enabling Java-Applet is embedded within 2-D bar code symbol. One or more HTML-encoded documents, including a framework-style HTML document, are created and stored in an HTTP server (2) for use in enabling the transaction process of the present invention. When a bar code symbol encoded with a transaction-enabling Applet is read using a bar code symbol reader (7A) interfaced with a Java-enabled Internet terminal, the corresponding HTTP document(s) are automatically accessed and displayed at the terminal, and the transaction-enabling Java-Applet initiated for execution so that the customer, consumer or client desiring the transaction can simply and conveniently conduct the information-related transaction over the Internet. The transaction-enabling Internet terminal can be in the form of an Internet kiosk installed in a public location, in the manner as conventional ATMs.
