Abstract:
[PROBLEMS] To provide an ID tag package for RFID, which performs excellent wireless communication regardless of existence of external metal or water and is strong against stresses from the external even under severe use environment, and to provide a RFID system using such package. [MEANS FOR SOLVING PROBLEMS] In the RFID system, an ID tag package (20) has a structure, which covers an ID tag (22) for RFID and has thicknesses (L1, L2) required for reducing electromagnetic wave attenuation due to existence of at least external metal or water. The RFID system includes an elastic layer (24) which can relax stresses from the external.
Abstract:
PROBLEM TO BE SOLVED: To provide a device and method for recognizing information held in an IC tag which can discriminate such a case that an IC tag is intentionally held over an antenna from the other case. SOLUTION: When a decision device 23 detects an IC tag, a clocking part 44 starts counting of an elapsed time. A determination part 43 monitors the change of the receiving circumstances of the IC tag. The decision part 43 decides that the reading of an IC tag has been performed by an operator's act to intentionally read the IC tag under conditions that all the next conditions are satisfied. A first condition shows that the IC tag is read by two antennas, read by only one antenna, finally read by the two antennas, and not read by the two antennas. A second condition shows that the preparation of the first condition has been completed within a specified time. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To manage as many articles as possible by using readers/writers as few as possible in an RFID system. SOLUTION: This RFID system is characterized in that the system includes an antenna system 30 for an RFID equipped with: a first antenna 38 which is able to communicate with an external reader/writer; an antenna switcher 36 connected to the first antenna 38; and a plurality of second antennas 34 which can be successively connected to the first antenna 38 through the antenna switcher 36, that is, the plurality of second antennas 34 which are able to communicate with an IC tag mounted on an object 39 placed in the region decided by the second antenna 34.

Abstract:
PURPOSE: To provide a portable computer which can easily and also cheaply reduce an electromagnetic wave noise emitted by an electric potential difference that is generated between a portable computer and a docking device for this portable computer, and the docking device for the portable computer. CONSTITUTION: A notebook type personal computer has a conductive contact part material 304 that is connected with the reference electric potential part of the personal computer main body inside a pair of recess parts 302 that are formed on the bottom separated from a connector, and a docking device has a conductive retaining riece 135A which is connected with the reference electric potential part of the docking device main body and can frequent from an opening 130A inside the opening 130A which is formed at the position that corresponds to the recess parts 302 of the personal computer when the personal computer is completely mounted. As the contact part material 304 and the retaining riece 135A are mounted on the position which is separated from the connector, the electric potential difference between the personal computer and the docking device can be removed.
Abstract:
PROBLEM TO BE SOLVED: To provide a storage case for enabling information of RFID tagged items to be accessed without opening the case, and capable of being formed even by materials such as metal etc. which is hard to make an electric wave passed therethrough, and to provide an RFID system using the case. SOLUTION: The storage case includes a built-in antenna disposed facing an antenna of an RFID tag to be mounted to the items, and performing communication with the RFID tags, and an outer surface coaxial connecter or a transmission reception antenna for relaying connected to the built-in antenna and provided on an outer surface of the case for performing communication with the external RFID reader/writer. The communication between the built-in antenna and the RFID reader/writer is performed by connecting the outer surface coaxial connecter with the RFID reader/writer, or via communication (electric power supply and data exchange) between the transmission reception antenna for relaying and the transmission reception antenna of the RFID reader/writer. The antenna for relaying may be provided separately from the case, and may be connected to the outer surface coaxial connector of the case. COPYRIGHT: (C)2008,JPO&INPIT
