  • 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.

  • Publication number: 20120035802
    Abstract: A learning diagnostic system for a working machine is capable of making a fault diagnosis of the working machine universally relative to various types of sensor information, and preventing a failure in the working machine by enabling a fault diagnosis even in a transient operating state that represents a transitional state between operating states. A state learning device 201 sorts inputted sensor data 101a into one under a steady operating state and one under a transient operating state, and generates, through learning, steady state data 102a and intermediate state data 103a, each including a permissible error. A state diagnostic device 202 uses the steady state data 102a to determine whether an operating state of the working machine related to the inputted sensor data is the steady operating state or the transient operating state, and make a fault determination in the steady operating state.

  • 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.
