  • Patent number: 5204526
    Abstract: A magnetic marker has a plurality of thin strips or wires of saturatable magnetic material having square .phi.-H characteristics and coercive forces different from each other. Amorphous magnetic material may be used. When the marker is subjected to magnetization reversal by an external magnetic field, variations of magnetic flux corresponding to a plurality of magnetization reversals can be chronologically detected as a voltage pulse train by detecting coils. By processing this voltage pulse train, a pattern can be made, recognized, so that the magnetic marker effectively identifies the kind of article to which it is attached. A magnetic marker reading and identifying apparatus has a plurality of exciting coils for producing a rotating magnetic field, with the axis of at least one of the exciting coils being orthogonal to the axis of at least one other exciting coil.

  • Patent number: 5202551
    Abstract: A reading device for an integrated circuit card includes a slide movable in an insertion direction of the integrated circuit card between a rest and an operational position and is loaded by a spring in a direction opposite to the insertion direction. The slide is blocked in its rest position by a locking device switchable between a blocking position and first and second release positions. The locking device is loaded by a further spring in the direction of the blocking position when the integrated circuit card is not inserted. At the end of an insertion movement of an integrated circuit card past a read position into an adjacent over position, the locking device is switched into its first release position by the integrated circuit card, whereby the slide is moved from its rest position into its operational position. During movement of the slide, a contact carrier is moved into contact with contacts on the circuit card.

  • Patent number: 5198649
    Abstract: The scanner and scanning method of the present invention effect bar code scanning to determine the bar code data printed thereon by repeatedly sweeping a scanning beam in scan paths across the labels. The bar code labels bear bar codes of the type which include a primary code portion and which may also include an Add-On code portion. The method of the present invention includes the steps of sweeping a scanning beam across the label until the beam sweeps the entire primary code portion in a first scanning pass along a first scan path; immediately sweeping the scanning beam across the label in additional scanning passes along additional scan paths adjacent and parallel to the first scan path; and, if the beam sweeps the entire primary code portion in the additional scanning passes, and, if an Add-On code portion is not scanned in part during either the first or additional scanning passes, then the data scanned during the first and additional scanning passes is accepted as valid scan data.

  • Patent number: 5189292
    Abstract: An optically encoded information bearing label containing a two dimensional array of data cells includes a finder pattern comprising a plurality of spots arranged in a predetermined geometric pattern substantially analogous to the predetermined geometric pattern of said two dimensional array of data cells. The finder pattern is detected by first scanning the image area to detect spots. The locations of detected spots are compared to the known geometry of the finder pattern in order to provide for rapid and reliable finding of the finder pattern and the information bearing label. Additionally, the detected finder pattern spots provide information for decoding the two dimensional data array in order to compensate for label magnification, tilt and other distortions.

  • Patent number: 5177346
    Abstract: A bar code reader system for reading bar code labels with highly specular spaces and bars with low contrast. The bar code label is illuminated with radiation polarized in a first direction. The radiation polarized in a first direction reflected from the bar code label is received and blocked by means of cross polarization. This blocked radiation is representative of the spaces and other radiation passing through unblocked is representative of the bars. The resulting radiation pattern representative of the bars and spaces is consequently inverted from its initial state into a secondary state. The radiation image passed by the block is detected in order to generate a signal representative of the bars and spaces. The strength of the signal representing the spaces is substantially diminished in intensity. The widths of the areas representing the bars and spaces is determined, and the widths representing the bars and spaces are interpreted to obtain the information of the bar code.
