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.
摘要:
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:
A tag access control system capable of setting an appropriate parameter for controlling a reader/writer can be provided. The tag access control system includes a control portion that controls data communication between an IC tag and a reader/writer by sending a command to the reader/writer in accordance with a parameter and receiving an execution result; and a parameter adjustment portion that adjusts the parameter to an appropriate value. The parameter adjustment portion includes a parameter change portion that changes the parameter a plurality of times, a result storage portion that records execution results of commands based on a plurality of parameters that are changed and a calculation portion that calculates an appropriate parameter based on the execution results stored in the result storage portion.

摘要:
An IC-tag reading necessity determination method and system include preparing success rate information indicating a rate of success of receiving a response from an IC-tag to a first signal each time a set or a plurality of sets of transmitting the first signal to the IC-tag a plurality of times is performed, performing processing to transmit a second signal to a target IC-tag from a reading apparatus a plurality of times to acquire response reception success/failure information indicating success/failure of reception of a response to the second signal; and determining whether the target IC-tag is to be read based on the success/failure of each time indicated in the response reception success/failure information and a rate of success of each time indicated in the success rate information.
摘要:
Simplified sharing of information among service-provision systems. A first message (Msg1) containing service information is transmitted from a first service-provision server (2a) to a first service controller (11a) [#1], wherein it is interpreted, and, for example, a second message (Msg2) is created from the service information contained in the first message (Msg1) and is transmitted to a message router (12) [#2]. The second message (Msg2) is further sent to a router controller (14) and interpreted [#3], and an action rule is determined [#4]. The action rule is executed by the message router (12), whereby the second message (Msg2) is transmitted to a second service controller (11b) [#5]. As a result, a portion of the service information contained in the second message (Mesg2) is extracted, and a third message (Msg3) is created and transmitted to a second service-provision server (2b) [#6]. The second service-provision server (2b) receives the third message (Msg3) and carries out processes corresponding to services that are provided.
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.
