  • Patent number: 6098881
    Abstract: Magnetic stripe documents are identified and authenticated on the basis of repeatable magnetic characteristics of a stripe recorded with digital data. Stripes are sensed to provide an analog signal, only a portion of which is used, specifically, the portion storing leading zeros. Cyclically, the leading zeros are sampled and digitized as a target number of samples using a frequency locked loop. The target number of samples for each zero is then reduced by a selection process that attains a predetermined number of digital samples that represent a magnetized portion of a leading zero, specifically, a space between data transitions. Groups of selected predetermined number of digital samples are then combined to provide a card magnetic characteristic identifier. Documents are verified by correlating reference and recent characteristic identifiers. Specific forms of sensor structures are utilized for the applications involving multitudes of different documents and sensor structures.

  • Patent number: 6095419
    Abstract: A demodulated data storage buffer is stored with bar width data sets obtained by scanning a coupon code with a scan optical system. A CPU first executes a demodulating process on these bar width data sets in accordance with a demodulation algorithm in a WPC code system. If an end guard bar (RGB) of the WPC code is contained in the demodulated data by the demodulating process, the demodulating process is executed on the same bar width data sets in accordance with a demodulation algorithm in a CODE 128 code system.

  • Patent number: 6095420
    Abstract: A bar code reader decodes a bar code in different directions if the bar code contains special characters whose bar widths have been corrected. The bar code reader compares the decoded results in the different directions with each other, to improve the bar code reading reliability. If the decoded results agree with each other, the results are accepted, and if not, they are discarded.

  • Patent number: 6092724
    Abstract: A secured network system comprising a readykey controller which has a first card reader and a power relay switch connected thereto. The user of the stem inserts a microchip embedded card into the first card reader which then transmits an authorization signal to the readykey controller. The readykey controller then activates a power relay switch affixed to the computer which connects the computer's power supply to an external power source activating the computer. The secured network system also has a data relay switch which includes a manual A/B secured network switch. The manual A/B switch allows the user to receive and process classified data, by setting the switch to a predetermined position which connects a secured network server to the computer. The user inserts his proximity card into a second card reader which transmits a second authorization signal to the readykey controller. The readykey controller, responsive to the second authorization signal, activates the data relay switch.

  • Patent number: 6082621
    Abstract: A multi-bit digitizer (30) for a barcode reader detects the presence of edges of a scanned barcode symbol, and also measures the strength of each detected edge. A polarity or edge direction signal (8) indicates the direction of each detected edge, and a timing signal (6) is representative of the timing and also, by means of a variable pulse width, the strength of each edge. A gating signal (200) indicates that the data are unreliable and invalid if the measured voltage applied to the scanner motor of the barcode reader is higher or lower than defined limit values. Any scans made at a speed which were too high or too low are rejected.

  • Patent number: 6082620
    Abstract: A liquid crystal dynamic barcode display apparatus includes a liquid crystal layer having a plurality of elongated barcode display elements positioned in close side-by-side parallel relation formed thereon. The barcode display elements are activated in patterns to form a barcode pattern which can be scanned by a conventional barcode scanner. Spacing between adjacent barcode display elements is less than that which can be detected by the barcode scanner such that multiple adjacent barcode display elements can be activated to form relatively wide bars of the barcode symbology. Preferably, the display apparatus also includes alphanumeric display elements which are simultaneously activated to form human readable symbols corresponding to characters represented by the barcode pattern.

  • Patent number: 6079621
    Abstract: A secure card such as a credit card having a magnetic strip thereon is disclosed. The magnetic strip is coated with a thin amorphous layer having electrical characteristics and a processor. In a first state, the amorphous layer acts to interfere with reading of information from the magnetic strip. Identification of a user of the card as an authorized user thereof results in a second state in which the information stored in the magnetic strip is accessible. For example, biometric identification or the use of a PIN entered either directly into the card or through an input terminal cause the processor to switch power from the amorphous strip thereby removing the interference and unmasking the information on the magnetic strip.

  • Patent number: 6079619
    Abstract: An identification tag is attached to or imbedded in each article a plurality of which are located nearby or stacked together. The identification tag wirelessly communicates with a remote controller such as a hand-held terminal to send data or receive command. Electric power to operate the identification card is also wirelessly supplied from the remote controller. The electric power is received only by a particular identification card which is communicating with the remote controller, and is turned off when the communication is completed. The electric power is then supplied to the next identification card which communicates with the remote controller. Thus, all the identification tags sequentially send data thereof one by one to the remote controller. The remote controller includes an indicator that indicates whether the communication with all the identification tags is completed, so that the remote controller can be positioned at a right place until the end of the communication.
