  • SECURITY DEVICE FOR PRODUCT PACKAGING
    Publication number: 20200364530
    Abstract: An RFID security device for product packaging is disclosed. The security device includes an RFID tag disposed on a first portion of a product package, and a booster antenna disposed on a second portion of the product package. The RFID tag and booster antenna are positioned on the product package so that the RFID tag will be electromagnetically coupled to the booster antenna when the product package is closed, and the RFID tag will be decoupled from the booster antenna when the product package is open.

  • Controllable read blocking based radio-frequency identification
    Patent number: 10521711
    Abstract: In some examples, a controllable read blocking based radio-frequency identification (RFID) device may include a substrate layer, and a trace formed of a conductive material and disposed on, partially within, or fully within the substrate layer. The controllable read blocking based RFID device may further include a controllable read blocking layer disposed on the substrate layer and the trace and including a fluid disposed in the controllable read blocking layer to selectively block or allow passage of electromagnetic waves to the trace to respectively inhibit or allow communication of a RFID reading device with the controllable read blocking based RFID device.

  • Thin film transition metal dichalcogenides and methods
    Patent number: 9991390
    Abstract: A coated substrate including a thin film of a transition metal dichalcogenide and associated methods are shown. In one example, the substrate is a semiconductor wafer. In one example, the thin film is atomically thin, and the substrate is a number of centimeters in diameter. In one example a crystalline structure of the thin film is substantially 2H hexagonal.
