  • Patent number: 8588686
    Abstract: A Method and system for remote power distribution and networking for passive devices is provided. In this regard, a sensor comprising a leaky wave antenna may be powered utilizing energy from a radio frequency signal received via the leaky wave antenna. The sensor may be operable to recover a baseband signal from the received radio frequency signal. The sensor may be operable to generate one or more sensor readings in response to the received baseband signal. The sensor may be operable to communicate the sensor reading to a source of the received radio frequency signal via a backscattered signal. The backscattered signal may be generated by controlling spacing between surfaces of the leaky wave antenna. The backscattered signal may be generated by switching a load in and out of a receive path of the sensor and/or by switching between a plurality of feed points of the leaky wave antenna.

  • Patent number: 8585988
    Abstract: The present invention relates to a method to turn cassettes for biological tissue samples into devices traceable with RFID technology, using a system with inlays tagged with an RFID chip, which inlays are placed in the tissue sample chamber of the tissue cassettes, wherein the part of the inlay that contains the antenna of the RFID chip is running around an opening or is folded together. Such inlays do not risk being affected by damaging forces outside the tissue cassettes. With an inlay that at every suitable moment can be positioned in the tissue sample chamber for one or more limited periods of time, or indefinitely, tissue cassettes can be tracked and traced with RFID technology without the fear of destroying the RFID chip during processing that involves the use of a microwave oven. During that period the inlay can be temporarily removed from the tissue cassette.

  • Patent number: 8581707
    Abstract: Systems for identifying and categorizing distributed devices, e.g., lighting fixtures and thermostats, is disclosed. In an embodiment, a user (200) sends a low power discovery message to devices (201) using a portable programming tool (100). The devices (201) within range respond with identification information. The portable programming tool (100) organizes the responses by proximity and sends a “flash” message to the device with the closest perceived proximity. That device responds with a visual or audible signal (202), allowing the user (200) to determine whether that device is the one intended for selection. If so, the user initiates a store routine in which identification information, including category information, is stored in one or more locations, such as, the selected device (201), the portable programming tool (100), and/or a central or local controller (1100). The identification and categorization can, for example, be used to automate load shedding and to reduce energy consumption.

The wireless-IC-device main component includes an insulating substrate, which is provided with a loop electrode and an electromagnetically coupled module coupled to the loop electrode. A signal from the reader/writer causes an eddy current to flow across a conductor principal plane of a metal article. The eddy current causes a magnetic field to be generated in a direction perpendicular or substantially perpendicular to the conductor principal plane of the metal article. Then, the loop electrode is coupled to the magnetic field. Thus, the wireless-IC-device main component functions as an RFID tag even for signals from the principal plane opposite to the wireless-IC-device main component. Thus, it is possible to reduce the cost of manufacturing a metal article, and to provide a wireless IC device using the metal article as a radiator.

An electronic device or tag paced at the edge of the cavity experiences a high electric field strength on account of this enhancement and is driven into operation.

  • Patent number: 8501120
    Abstract: A method and apparatus for providing more reliable wireless communication and power to sensors in electrically challenging bioprocess environments is disclosed. An unconnected antenna is located within the bioprocess environment, preferably in the same plane as the primary powered antenna. This unconnected antenna, also referred to as reflective antenna, enhances and confines the electromagnetic field created by the powered antenna. This reflective antenna is incorporated in or proximate to the devices containing a sensor or communication device. In one embodiment, the reflective antenna is incorporated into the filter housing. In another embodiment, it is incorporated into the filtering element itself. In another embodiment, it is incorporated into or affixed on the disposable bioprocess components, such as bags and tubes.

  • Patent number: 8497776
    Abstract: A radio frequency identification (RFID) system used to perform electronic article surveillance comprises a RFID tag and a RFID reader. The RFID tag is affixed to an object, and the RFID reader, having a plurality of antennas, is in radio frequency (RF) communication with the RFID tag. The plurality of antennas are arranged to have a spatial relationship with one another to monitor and communicate with the RFID tag such that a likelihood of a security breach of the RFID tag is determined. Determining the likelihood of the security breach is based, at least in part, on a signal strength of a read of the RFID tag at each antenna relative to the plurality of antennas.

  • Patent number: 8493215
    Abstract: A communication antenna has a rectangular radiating section, and has a structure that emits an electric field of linear polarized waves only in a vicinity of the radiating section of the antenna. An RFID tag has an IC chip and a tag antenna that is long in a predetermined direction. The tag antenna has a main antenna portion that is rectilinear and extends over substantially an entire length in a longitudinal direction of the tag antenna, and folded-over antenna portions at which currents induced by an external electric field offset one another due to portions that extend in mutually different orientations in the longitudinal direction. A parallel interval between the main antenna portion and a first folded-over antenna portion exceeds a width of the radiating section of the communication antenna.

  • Patent number: 8479999
    Abstract: A composite magnetic antenna for information communication utilizes a magnetic field component as well as a composite RF tag using the composite magnetic antenna, which can be embedded in metals while maintaining a sufficient communication sensitivity unlike conventional RF tags which are unusable in the metal embedding applications. The composite RF tag for transmitting and receiving information using an electromagnetic induction method includes a magnetic antenna on which an IC is mounted, and an insulating material and a metal material or a conductive material which are formed around the magnetic antenna. The magnetic antenna includes a central core formed of a magnetic material, and an electrode material formed into a coil around the central core. The insulating material is formed around the magnetic antenna except for one longitudinal end of the coil of the magnetic antenna. The metal material or the conductive material is formed on an outside of the insulating material.
