Abstract: A bar code symbol scanning system for laser scanning bar code symbols within a 3-D scanning volume and automatically producing bar code symbol position information specifying the position of each bar code symbol detected within said 3-D scanning volume. The system comprises a laser scanning mechanism and a scan data signal processor. The laser scanning mechanism generates and scans a laser beam so as produce a laser scanning pattern which is substantially confined within a 3-D scanning volume having a plurality of focal planes. During system operation, the laser scanning pattern, consisting of a plurality of scanlines disposed within each focal plane, scans the bar code symbol on each object transported through the 3-D scanning volume. In response thereto, the laser scanning mechanism automatically produces scan data indicative of the scanned bar code symbol.

Abstract: A bar code scanner for stationary disposition at a counter to projecting a scanning pattern comprising first, second, third, fourth and fifth groups of parallel scan lines within a relatively narrow, yet diverging, volume, e.g., pyramid, cone, etc., centered about a projection axis. The scanner includes a compact housing mounted on an adjustable base. The housing includes a window, five stationary mirrors, a laser diode, a rotating reflective polygon for sweeping the laser beam from the diode across the mirrors and out a window so that the projection axis is substantially but not precisely perpendicular to the window. The scanner also includes a fixed curved collecting mirror and a concentrating lens to focus light which is reflected off of a bar code to a photodetector. One mirror extends along an axis parallel to the transverse axis to produce the first group of scan lines.

Abstract: The first scanner generates an omnidirectional laser scanning pattern within a large 3-D scanning volume in order to detect the location of a code symbol therewithin and produce data indicative of its location therewithin. Using this location data, the second scanner produces a high density scanning pattern to aggressively scan the region in which the code symbol has been detected, and collect scan data for decode processing. In the illustrative embodiment, the first scanner is realized as a multiple-focal plane holographic scanner, whereas the second scanner is realized as a high-speed 2-D scanner. By virtue of the system and method of the present invention, it is now possible to read bar code symbols located anywhere within very large volume of space, with a high degree of accuracy hitherto impossible using prior art techniques.

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.

Abstract: 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 an 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 laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

Abstract: An automatic bar code symbol reading system for automatically reading bar code symbols on packages transported along a conveyor belt through a 3-D scanning volume. The system includes a holographic-based bar code symbol detector and a bar code symbol scanner mounted above the conveyor belt. The holographic-based bar code position detector produces a first laser scanning pattern within the 3-D scanning volume, and scans each transported package, detects the position of the bar code symbol therein, and automatically produces bar code position data specifying the position of the detected bar code symbol. In automatic response to the produced bar code position data, the bar code symbol scanner is steered so as to collect light reflected off the detected bar code symbol, and produce scan data indicative of the detected bar code symbol.

Abstract: A code symbol driven system and method are disclosed for producing graphical user interfaces which enable prespecified information-related transactions over the Internet. In the illustrative embodiment, the code symbol reader is integrated with a Java-enabled Internet terminal. The code symbol reader is used to read a code symbol (e.g., magstripe or bar code) encoded with information related to or specifying a predetermined Uniform Resource Locator (URL).

When the code symbol is read using the code symbol reader, and data representative of the URL is provided to a Java-enabled browser program, the corresponding HTTP document is automatically accessed and displayed at the terminal.

Abstract: A holographic laser scanner for scanning bar code symbols, in which a plurality of scanning planes are projected through a plurality of different focal regions in order to provide, at each such focal region, a plurality of scanlines that are substantially confined within the highly-defined 3-D scanning volume of the holographic laser scanner. This remarkable capability of the system ensures that the scanlines of the holographic scanner extend only where scanning is required (e.g., within the highly-defined 3-D scanning volume). This avoids scanning regions of space where bar code symbols are known to not be present, or collecting scan data from such “empty” regions of space. By virtue of the present invention, the highly-defined 3-D scanning volume of the holographic laser scanner can be easily positioned above a doorway, conveyor belt, loading dock or the like where objects bearing bar code symbols are expected to pass.

Abstract: A universal transaction machine (UTM) is disclosed, wherein a code symbol reader is integrated with a Java-enabled Internet terminal to enable the reading of a code symbol (e.g. magstripe or bar code) encoded with information related to a predetermined Uniform Resource Locator (URL). The predetermined URL specifies the location of a HTML-encoded document stored in an HTTP server and contains one or more transaction-enabling Java-Applets. When the URL-encoded symbol is read using the code symbol reader and provided to the Java-enabled browser program, the corresponding HTTP document is automatically accessed and displayed at the terminal. Preferably, the transaction-enabling Java-Applets are executed in order to produce a graphical user interface on the display screen of the terminal, thereby enabling the user to carry out data read and entry operations related to the prespecified information-related transaction.
