Patent number: 7982611Abstract: Rogue RFID readers are detected by listening to communication between rogue reader and a tag, capturing a time stamp and/or a channel associated with the communication, and checking the captured time stamp/channel to determine whether it is a result of a command from another legitimate reader. Audible or visible alerts may be issued, flags may be set, or messages transmitted to an administrator upon determining the operation of the rogue RFID reader. Based on the alert(s) affected tags or the rogue reader may be jammed or an effect of the illegal transmission by the rogue reader may be reversed or tags replaced.Type: GrantFiled: November 17, 2008Date of Patent: July 19, 2011Assignee: Impinj, Inc.Inventors: Brent A. Picasso, Paul Dietrich, Michael J. Dacquisto, Joseph Baird, Christopher J. Diorio, Harley K. Heinrich

Patent number: 7982609Abstract: An “RFID-Based Inference Platform” provides various techniques for using RFID tags in combination with other enterprise sensors to track users and objects, infer their interactions, and provide these inferences for enabling further applications. Specifically, observations are collected from combinations of RFID tag reads and other enterprise sensors including electronic calendars, user presence identifiers, cardkey access logs, computer logins, etc. Given sufficient observations, the RFID-Based Inference Platform automatically differentiates between tags associated with or affixed to people and tags affixed to objects. The RFID-Based Inference Platform then infers additional information including identities of people, ownership of specific objects, the nature of different “zones” in a workspace (e.g., private office versus conference room).Type: GrantFiled: June 18, 2008Date of Patent: July 19, 2011Assignee: Microsoft CorporationInventors: Venkata Padmanabhan, Lenin Ravindranath Sivalingam, Piyush Agrawal

Patent number: 7982616Abstract: This disclosure describes a radio frequency identification (RFID) tag that includes a three-dimensional (3D) loop antenna. The 3D loop antenna includes a first conductive portion having a length and width that substantially exceed a thickness. The length and width of the first conductive portion substantially lie in a first plane. The 3D loop antenna includes a second conductive portion having a length and width that substantially exceed a thickness. The length and width of the second conductive portion substantially lie in a second plane that is substantially parallel to the first plane. An RFID circuit electrically connected to the loop antenna excites a current through the first and second conductive portions in a current loop that lies in a third plane that is not substantially parallel to the first and second planes. In some instances the third plane may be substantially perpendicular to the first and second planes.Type: GrantFiled: June 20, 2008Date of Patent: July 19, 2011Assignee: 3M Innovative Properties CompanyInventors: Swagata R. Banerjee, Robert A. Sainati, William C. Egbert, David K. Misemer

Patent number: 7980477Abstract: A dual interface inlay having a bottom sheet; an antenna wire mounted to the top surface of the bottom sheet; end portions of the antenna wire formed with squiggles or meanders forming contact areas of increased surface area for subsequent attachment of a chip or chip module to the antenna wire; conductive material applied to the end portions of the antenna wire; a top sheet disposed over the bottom sheet for lamination thereto; and recesses formed in a bottom surface of the top sheet, at positions corresponding to the contact area. The antenna wire may be insulated wire, and insulation may be removed from the end portions of the antenna wire. Silicon cushions may be disposed in the bottom sheet under the contact areas.Type: GrantFiled: May 9, 2008Date of Patent: July 19, 2011Assignee: Féinics Amatech TeorantaInventor: David Finn

Patent number: RE42777Abstract: A simple trip-wire or magnetic circuit associated with a shipping container provides continuity, which is detected electrically. Simply, if continuity is disabled by a forced entry of the container, electrical detection means, such as a radio-frequency-identification (RFID) tag, will alert the owner or monitoring station. The trip-wire concept would require the replacing of a broken trip wire (resulting from forced entry), while the magnetic circuit concept can be reused repetitively. In a second embodiment a magnetic circuit and the detection device (RFID tag) are embedded into the shipping article during manufacturing. The preferred detection device, an RFID tag, could also be a battery backed transceiver type on which a replaceable or rechargeable battery could be mounted on the inside of the shipping container during manufacturing. The RFID tag would communicate with an interrogator unit, which could be connected to a host computer.Type: GrantFiled: March 27, 2008Date of Patent: October 4, 2011Assignee: Round Rock Research, LLCInventor: John R.
