  • Patent number: 8564440
    Abstract: When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.

  • Patent number: 8111163
    Abstract: Disclosed is a cable identifying system for accurately discriminating one cable from another on site over a long period of time, the system enabling a cable layer or a cable user, when laying out an RFID built-in cable, to do without manually writing any information in the RFID tags built in the cable. One cable having RFID tags built therein can be accurately realized. The individual ID's of the RFID tags are read and stored in a storage apparatus. When a part of the cable is cut, the ID's of the RFID tags nearest to the both end of the cable are read out, and the ID-related data of the RFID tags in the cut-out cable are recorded on a desired medium or electronic information medium.

  • Publication number: 20100224328
    Abstract: An RFID built-in cable manufacturing device including: an RFID applicator for sticking an RFID tag onto a composite strand; a sheath molder for providing sheath for the composite strand on which the RFID tag has been stuck at the RFID applicator with resulting an RFID built-in cable; an RFID reader for sequentially reading ID of the RFID tag as the RFID built-in cable is fed to a cable take-up drum; and a server for storing data having been read out by the RFID reader.
