  • Patent number: 6719634
    Abstract: A system for loading, through a shop terminal, a game application into an IC card which disables playing of the game after a plurality of times in the same pattern by invalidating the game pattern when the play is completed and program log data is stored in the IC card. The log data is collected by a management server for each connection of the IC card and the shop terminal so as to administrate the collected data to enable dynamic management of game parameters, thereby the game application may be safely introduced to the IC card system, thereby increasing a user desire to use the card.

  • Publication number: 20040060979
    Abstract: A terminal device capable of operating with a smart card which includes a storage device and an input/output interface. The storage device stores an application program having at least one component that can run under an operating system in the smart card and an interpreter for interpreting scripts. The terminal device includes an operating system which executes loading of a command to exchange game scripts and scripts to be exchanged with a script stored in the smart card via the input/output interface. The scripts define a sequence of executing components included in the application program.

  • Patent number: 6681995
    Abstract: A method enables loading/unloading of a plurality of types of games as part of an application program, typically, a game application program installed on a smart card system with a high ability to store information for which highly-reliable security is achievable, extending the range of use of the card. Of a Program to run on the card, the processing parts that can be executed in common are packaged as modules and game definitions described in scripts are loaded/unloaded into/from the card as required from a terminal operating with the card. In the program, a script interpreter that interprets and executes scripts, a controller that controls the loading/unloading of scripts, a controller that performs the management of point data and rights to play a game are provided, whereby dynamic loading/unloading of types of games is possible and one application can offer a plurality of types of games that can be selectively executed.

  • Patent number: 6612486
    Abstract: In the case where a card issuer and a service provider are different in operating and managing a smart card for multi-application programs, when the card issuer sends a request of sending an initial load application program personalized when initially issuing the card to the service provider, the service provider can not select a proper application program and determine an object for personalizing. This is solved by assigning a unique number to the smart card issue application form for cooperating the card issuer with the service provider.

  • Publication number: 20020056079
    Abstract: A method, by which if a reissued smart card is issued based on an old smart card, the application program loaded in the old smart card is smoothly reloaded in the reissued smart card, is disclosed. Its specific configuration will be described as below. A method for loading an application program in a smart card comprises the steps of: in response to a request for loading one application program for a smart card in the smart card that has been reissued based on an old smart card, judging whether or not said one application program was loaded in the old smart card, according to a relationship between a card id of the reissued smart card and a card id of the old smart card; and if it is found out that said one application program was loaded, loading said one application program in the reissued smart card.

  • Patent number: 5612959
    Abstract: Distributed LANs are connected to a wide area network through terminal adapters, which are interconnected by virtual circuits to form a logical bus network. Each terminal adapter copies cells received through the virtual circuit that is allocated for multicasting, and transfers the copied cells to the adjacent terminal adapters via preset virtual circuits. The terminal adapters assemble a part or all of the transmitted message from the received cells and, according to the contents of the assembled message, transfer the copies of the cells to the adjacent terminal adapters through predetermined virtual circuits.

  • Patent number: 5604910
    Abstract: The present invention relates to a method of search in which a plurality of candidate of character strings likely to coincide with a designated key word are detected from a text character string, and it is decided whether the candidate character strings detected include a character string coincident with the key word character string. Further, the sequence of detection of character string candidates is determined in such a manner that a portion having a succession of characters coincident with any of a plurality of characters included in the key word character string is selected as a candidate character string.

  • Patent number: 5226135
    Abstract: A vector processor is provided for nonnumeric processing, and more particularly for performing a sort method which performs sorting at a high speed. It is an object to provide a method for sorting, by vector processing, keys whose lengths are longer than a sortable given length determined by the vector processor. In the sort method, partial keys of the keys which are equal in length to the given length are extracted and they are sorted by the vector processing. If there are partial keys of the same value as a result of the sorting, the succeeding partial keys of those partial keys having the same value are extracted and they are sorted. In this manner, the sorting of the original keys is permitted. The vector processor is provided with circuits for extracting the partial keys, sorting and detecting the partial keys having the same value in the sorted partial keys, all by vector processing.
