  • Patent number: 6164545
    Abstract: A scanner for reading two-dimensional optical information sets is described which includes a housing for supporting a photosensitive array associated with an optical string adapted to focus optical information on the array. Also provided are array and optical string controls for controlling the array and optical string such that the output of selected images on the array are processed via pattern recognition techniques. Images recognized to contain decodable optical information are displayed and highlighted by a display. In addition, the scanner provides autodetect circuitry for determining the type of terminal to which it is attached and automatically converts the two-dimensional code information into an appropriate one dimensional format, as needed, for communication to an attached terminal.

  • Patent number: 5955720
    Abstract: A semi-retroreflective optical scanning system has an optical scanning element which directs a scanning light beam via a stationary holographic optical element in a scan path across indicia to be read. Light from the indicia is collected by an optical collector, such as a lens or a mirror, which focuses it onto a small optical detector via the scanning element. The field of view of the optical detector scans across the indicia in synchronization with the outgoing scanning beam from the holographic optical element. Since the incoming reflected light is not limited by the aperture of the scanning element, the signal-to-noise ratio remains high even when a small scanning element is used. In a further embodiment the light source, scanning element collector and detector are provided in a common plane, the collector and scanning element sharing a common optical axis and a light source being provided substantially off axis to allow reduction in the scanning element size.

  • Patent number: 5939697
    Abstract: An evaluation system having one or more scanner units providing arrangements to enable the computer controlled, rapid setup and calibration of each included scanner unit to be employed for evaluation. The calibration is effected with specific settings established using stored calibration parameter groups. The calibration parameter groups, which are previously determined using special calibration targets, are stored and available for later recall and use, as needed. The evaluation system arrangements provide for slidably mounted scanner units to enable the distance between the scanner unit and a target indicia to be adjusted to a known distance to produce a selected spot size for the subsequent evaluations. A computing unit is provided having a memory to store the plurality of calibration parameter groups, with each stored calibration parameter group available to provide parameter values to be applied for use with the included scanner units.

  • Patent number: 5917172
    Abstract: When bar code data of a left or right block flanked by a guard bar and a center bar is input, several characters including the first character are demodulated, and a decision is made as to whether demodulation should be continued or not. If demodulation has already been performed a specified number of times, or demodulation free from significant distortion has already been performed, on the block currently subjected to demodulation, the demodulation process is discontinued and demodulation is not performed on the remaining characters.

  • Patent number: 5902990
    Abstract: A scanner guide for attachment to a pre-existing bar code scanner wand to enable such a wand to read bar coded labels disposed on a cylindrical surface of a relatively small diameter such as containers used for the collection of medical specimens. The scanner guide includes a cylindrical pin having a mounting base for positioning the same in generally parallel relation to a center axis of the scanner wand at a predetermined distance therefrom based upon the diameter of the cylindrical containers whereon the bar coded labels are disposed. A bottom surface of the mounting base is shaped to conform to the contour of the wand whereon it is to be mounted. In such an arrangement the scanner wand is held at a proper disposition in relation to the bar coded label as it is passed in a longitudinal direction over the same on the cylindrical surface.

  • Patent number: 5886337
    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.

  • Patent number: 5883375
    Abstract: Disclosed is a fully automatic bar code symbol reading system having an 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 prior to its 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. In the 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.

  • Patent number: RE36596
    Abstract: A filing system is provided for locating a particular file contained in a file holder which contains a plurality of files. The apparatus includes a machine-readable code mounted on each of the files, a guide attached to each file holder, a scanner for reading the codes on the files in a file holder, and an indicator for indicating when the particular machine-readable code corresponding to the particular file is located. The apparatus uses an improved bar code in which character boundaries are eliminated and the number of ONE's and ZERO's in a code are variable, resulting in increased data density. The unique numeric values which result from the improved bar code sparsely populate the possible range of values, and therefore a mapping algorithm is provided to map the bar code values to a sequential numeric system for ease of use.
