  • Patent number: 6126070
    Abstract: An IC memory card for use with a host information processing has an interface with the host information processor, a common memory having one or more IC memories and a security circuit for prohibiting access to the common memory if address data input from the host processor does not coincide with preset data. The IC memory card may further provide with an attribute memory which stores a security data and attribute information about the IC card wherein the security circuit checks not only the address data but also the data read out from the attribute memory to enhance the security.

  • Patent number: 6126075
    Abstract: An amplifier has an input responsive to an optical detector. An analog-to-digital converter is responsive to an output of the amplifier. A processor activates an optical emitter, and reads a first sample from the analog-to-digital converter. Upon determining that the first sample is less than a first threshold, the processor applies a first signal to a control input of the amplifier for a first duration. The processor reads a second sample from the analog-to-digital converter. Upon determining that the second sample is greater than a second threshold, the processor applies a second signal to the control input for a second duration less than the first duration.

  • Patent number: 6126077
    Abstract: Method and apparatus for providing communication with a higher communication rate while maintaining the occupied frequency band narrow, a signal processing unit of a reader/writer unit Biphase Shift Keying (BPSK)-modulates data to be transmitted, and thereafter outputs the modulated signal to a modem. The modem Amplitude Shift Keying (ASK)-modulates the modulated signal and outputs the ASK-modulated signal to a first loop coil. The first loop coil generates a magnetic field corresponding to the modulated wave. An IC card converts a part of the magnetic field radiated from the reader/writer unit with another loop coil to generate a power source from the electrical signal, and also extracts the data transmitted. In the case of transmitting the data to the reader/writer unit, a load of another loop coil is changed in accordance with the data. The reader/writer unit detects, with the first loop coil, any change in load of another loop coil of the IC card magnetically coupled with the first loop coil.

  • Patent number: 6126078
    Abstract: An identification medium with passive electronic data carrier and contactless, encoded communication with an associated read and write station (WR) has in a memory (42) a data organization with a common data field (CDF), with invariable, uncopiable master data (44), with a segmentable application data field (ADF), in which several independent applications can be written in application segments S1, S2, S3). A hierarchical authorization system (A) valid for all the identification media (IM-S) and all the read and write stations (WR) is established, with which each identification medium (IM-S) must be initialized and which ensures the mutual uninfluenceability of all the independent applications.

  • Patent number: 6119944
    Abstract: A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

  • Patent number: 6116507
    Abstract: A dot code recorded on an information recording medium consists of a data code corresponding to the contents of multimedia information to be reproduced, and a pattern code for determining a read reference point for the data code. The pattern code consists of pattern dots arranged at predetermined positions with respect to the data code, and markers arranged at predetermined positions with respect to the pattern dots and used to detect the pattern dots. In an information reproduction system for optically reading and reproducing a dot code from an information recording medium on which such a dot code is recorded, the dot code is imaged by an image input section. A data read reference point determining section then recognizes the pattern code from the picked-up image, and determines a data read reference point for reading the data code. A data reading section reads the data code on the basis of the data read reference point determined by thus data read reference point determining section.

  • Patent number: 6116510
    Abstract: A code pattern image printed/recorded on a recording medium and adapted to be picked up and read is electronically taken up and read and then processed by a decoder to restore the original data, which is then transformed into an image data of the code pattern image by an encoder and printed/recorded on another predetermined recording medium to reproduce the code pattern image by a printer. The code pattern image printed/recorded on the recording medium is made to contain an operation control data for permitting or prohibiting the operation of the encoder and the operation control data is extracted from the code pattern image by an operation control data extracting unit so that encoding operation control section permits or prohibits the operation of the encoder according to the extracted data.

  • Patent number: 6112981
    Abstract: A system and method to adapt a fuel dispenser and related facilities to accept bar coded cards in addition to or instead of magnetic strip cards. A standard bar code reader is used in conjunction with a magnetic strip card reader. The bar code reader includes a light detector and a light source. The light detector and light source are secured so that they may visually access a card in the magnetic strip card reader. This allows the light detector to access bar coded data that is printed on a bar coded card. Furthermore, the addition of the bar code reader does not prevent the magnetic strip card reader from also reading a magnetic strip if it is present on the card. When a bar coded card is slid into the magnetic strip card reader, the bar code reader interprets the signals generated thereby and "decodes" the signals into corresponding numbers. These numbers are then sent over a data bus to a controller, where they are interpreted.
