  • Publication number: 20230136728
    Abstract: This disclosure includes, and results in the creation of, a printed carbon nanotube and/or graphene hybrid antenna and/or EMI shield, comprised of a conductive layer that comprises a metal mesh (MM) layer or a nanowire layer on a substrate, with a printed Signal Enhancement Layer (SEL) on the conductive layer. The SEL includes an ink that includes one or both of carbon nanotube (CNT) and graphene. The circuit pattern results after the “exposed” conductive layer (i.e., the regions where the CNT/graphene ink is not printed) is removed via chemical etching or mechanical cutting. The structure (the antenna/EMI shield) is preferably but not necessarily transparent.

  • Patent number: 9904895
    Abstract: A guest monitoring and identification system is shown. The system comprises an RFID carried by a guest and includes therein programmed predetermined data identifying a guest. An activating transmitter transmits a monitoring signal over a designated area to be traversed by a guest having the RFID. A receiver receives from the RFID a transmitted data signal containing the programmed predetermined data identifying the guest. A guest identification and service information processor receives the transmitted data signal. The processor interprets the programmed predetermined data identifying a guest and generates data/information signals providing the name and service profile for an identified guest. A communication device communicates to service staff the name and service profile for an identified guest.
