A tag access control system for controlling data communication between a plurality of reader/writers respectively having a plurality of antennas and one or more IC tags moving sequentially through communication ranges of the plurality of antennas includes a storing portion for storing movement information and reader/writer information, a command accepting portion for accepting a command, a dividing portion for generating a plurality of divided commands from the command, a detecting portion for detecting the IC tag located within the communication range of the antenna in one reader/writer of the plurality of reader/writers, a job controlling portion for sequentially assigning the plurality of reader/writers the plurality of divided commands according to the movement information and the reader/writer information, and a returning portion for returning a result of processing the command. In this way, the tag access control system can improve a success rate of reading data from and writing data in a plurality of IC tags without lowering a moving velocity of articles.
摘要:
The reader/writer repeatedly reads data, which is stored in an IC tag existing in an area where communication with the reader/writer can be established, from the IC tag in a noncontact method. The reader/writer transmits the read data to the administrative device. The administrative device generates read data which shows the result of reading in chronologic order and generates feature data indicative of the feature of the result of reading on the basis of the generated time series data. An IC tag is sorted as a target tag or an unnecessary tag by sorting the read data as necessary data or unnecessary data on the basis of the generated feature data.

An information processing apparatus that conducts positioning on the basis of received signal strength indications obtained from access points, includes, a contact information detector that detects contact information between the information processing apparatus and a dielectric body, a recording module that stores a gain table including gain data corresponding to obtained contact information, a gain data correcting unit that extracts the gain data corresponding to the contact information obtained by the contact information detector from the gain table of the recording module and corrects gain by using the extracted gain data, and a positioning module that conducts the positioning by using the gain obtained by the correcting unit and the received signal strength indications.
摘要:
An active tag device includes a controller to cause the wireless communication unit to carry out data transmission at intervals of a first period, and to cause to start measurement of a second period set for determining a timing for causing a wireless communication unit to carry out carrier sense to detect data output by a reading writing apparatus, synchronously with the data transmission, and to cause the wireless communication unit to carry out the carrier sense after the second period elapsed. The reading writing apparatus includes a controller to cause to start measurement of the first period set for synchronizing with carrier sense of the active tag device after a wireless communication unit detected reception of data from the active tag device, and to cause the wireless communication unit to carry out data transmission to the active tag device during the second period after the first period elapsed.
摘要:
A group contact system includes a server 4 for managing user information, and a plurality of user terminals (2) which mutually and commonly engage in a communication service operated on the server. The user terminal (2) includes a card forming instruction means (5) and a content acquiring means (9). The server (4) includes a user information storage means (7) and a card forming means (8). Members who establish communications in, for instance a chat of the communication service, are eligible to be designated a group member. Anyone using the service can request that the server form a group card. Every item to be included in the group card has an access level that may be set by a user so that certain items may be excluded from the group card. As a result, the group card for user A may not have the same items as a corresponding card for user B. The group members acquire the formed group card and save the content of the formed group card. The invention also permits any group member to mutually make contact with other members by using the information on the card to access another communication means such as a telephone or a facsimile. Also, a snapshot of each member of the group members may be included on the card. Therefore, a friendship may develop among the group members.

An information processing apparatus includes a user interface, a switching unit, and a computer. The user interface is for a user that operates a first processing unit that runs a first operating system or a second processing unit that runs a second operating system. The switching unit selectively switches between the first processing unit and the second processing unit to be associated with the user interface. The computer functions as the first processing unit. The computer functions as the second processing unit. The computer runs a first application program on the first operating system. The computer activates, on the second operating system, a second application program related to the first application program, in a state in which the first processing unit is associated with the user interface. The computer controls the switching unit upon completion of the activation of the second application program.
