  • Patent number: 9514431
    Abstract: A system for monitoring a plurality radio frequency identification tags is described. The system uses at least one set of radio frequency identification tags. Each tag is attached to a container and includes several sensors for detecting physical conditions of said container. The system includes at least one autonomous intermediate reader in wireless communication with the frequency identification tags. The intermediate reader includes external wireless communication system, intermediate reader logic controller, and a self-contained rechargeable power supply. The system uses a central status reporting system in communication the intermediate reader.
    Type: Grant
    Filed: August 4, 2014
    Date of Patent: December 6, 2016
    Assignee: UChicago Argonne, LLC
    Inventors: Han-Chung Tsai, Yung Y. Liu, Hok L. Lee, Brian Craig, Kevin Byrne, Ketan Mittal, Justin C. Scherer

  • Patent number: 8013744
    Abstract: An enhanced method and apparatus are provided for tracking and managing a plurality of packagings, particularly packagings containing radioactive and fissile materials. A radio frequency identification (RFID) surveillance tag is provided with an associated packaging. The RFID surveillance tag includes a tag body and a back plate including predefined mounting features for mounting the surveillance tag to the associated packaging. The RFID surveillance tag includes a battery power supply. The RFID surveillance tag includes a plurality of sensors monitoring the associated packaging including a seal sensor. The seal sensor includes a force sensitive material providing a resistivity change responsive to change in a seal integrity change of the associated packaging. The resistivity change causes a seal integrity tag alarm. A tag memory stores data responsive to tag alarms generated by each of the plurality of sensors monitoring the associated packaging.
