    Abstract: A radio frequency identification (“RFID”) method, computer-readable medium, apparatus, and system are provided. In one embodiment, the method acquires dimensions of an item. The dimensions and speed of the item are used to determine the item's location on a conveyor (i.e., to track the item on the conveyor). The location of the item is used to determine which switch RFID reader antenna in a plurality of RFID reader antennas is the most suitable RFID reader antenna to communicate with a transponder located on the item. In other embodiments, the apparatus, system, and computer-readable medium are also provided which perform similar features recited by the above method.

    Abstract: A planar laser illumination and imaging system for illuminating an object and forming an image thereof. The planar laser illumination and imaging system which comprises an image formation and detection module having a field of view (FOV) focused at an image detecting array. A planar laser illumination array (PLIA) constructed from an plurality of planar laser illumination modules (PLIMs) is arranged in rectilinear manner. Each planar laser illumination module comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged therewith to produce a planar laser illumination beam component; and wherein the individual planar laser illumination beam components produced from the plurality of planar laser illumination modules are optically combined to produce a composite substantially planar laser illumination beam having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of the image formation and detection module, so that laser light reflected off an object illuminated by the planar laser illumination beam is focused along the field of view and onto the image detecting array to form an image of the illuminated object.

    Abstract: An automatic bar code symbol reading system provides a hand-supportable laser bar code reading device which can be used in either an automatic hands-on mode of operation, or in an automatic hands-free mode of operation. The system includes a scanner support frame for supporting the hand-supportable device in a user-selected mounting position, and permits complete gripping of its handle portion for use in the hands-on mode of operation. In general, the hand-supportable bar code reading device has long-range and short-range modes of object detection, bar code presence detection and bar code symbol reading. Pursuant to one illustrative embodiment, the long-range mode is automatically selected when the hand-supportable bar code reading device is placed within the scanner support stand during the automatic hands-free mode of operation. When the hand-supportable bar code reading device is picked up from the support stand and used in its hands-on mode of operation, the short-range mode is automatically selected to provide CCD-like scanner emulation. When used in either mode of operation, the automatic bar code reading device is capable of reading, in a consecutive manner, one or more bar code symbols on an object, while preventing multiple reading of the same bar code symbol due to dwelling of the laser scanning beam upon the bar code symbol. The automatic bar code symbol reading system of the present invention is disclosed in several different mounting arrangements at a point-of-sale station, illustrating novel methods of reading bar code symbols using the automatic hand-supportable optical scanning device of the present invention.
