Our Patents

  • (1) cloud-based, RFID-indexed system requiring contemporaneous data entry;

    (2)cloud-based RFID index system providing a map indicating assets with different ownership or different function

    A system for managing underground assets with RFID tags provides for expanded virtual storage by wirelessly linking the field RFID tag reader to a centralized database through a unique series code in the RFID tag. Real-time updating of information about underground assets coordination between multiple users may be accomplished through use of the central database as an information broker.

  • A monument usable for locating stationary geographical positions and/or assets includes a housing, comprising a body and a cap; at least one permanent magnet mounted on or in the housing; and at least one electronic marker located on or in the housing. The magnet has a magnetic field of sufficient strength for its location to be readily identified from outside the housing using a portable magnetic locator and the electronic marker includes an electronic transceiver for receiving and/or transmitting electronic information unique to the geographical location and/or functional properties of the monument or an asset associated with the monument.

  • Magnet plus UHF RFID tag with reflector.

  • A packaging structure for a four-channel integrated tunable laser array chip (100) comprises a carrier (200), a cryogenic refrigerator (300), a lens assembly (400), an isolator assembly (500), a package (600), a transition ring (700), and a thermistor. The packaging structure for the four-channel integrated tunable laser array chip (100) can realize a flexible tuning upon an active coupling of optical paths and ensure a reasonable switching of optical paths between optical assemblies, thereby improving a coupling efficiency for the optical paths and increasing a transmission distance of a digital signal. Furthermore, a design of a radio frequency circuit ensures integrity of a transmitted signal and reduces loss during the transmission. See full description

  • An RFID tag for marking storm drains incorporates the tag circuitry into a dome decal providing a flexible substrate capped by a self-leveling clear polymer. The RFID tag is placed between the polymer and the substrate on an electromagnetic radiation decoupling layer allowing a low profile fitting within the decal while allowing the decal to be used on metal drain surfaces. The decal includes a printed environment-promoting message relating to connection of the storm.
