  • Patent number: 8395515
    Abstract: A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. Each compliance badge receives dispense event signals corresponding dispenser identification information associated with dispense events initiated by the wearer of the compliance badge. The badges store dispense event records associated with each dispense event initiated by the wearer and thus keep track of all dispense events initiated by the wearer of the compliance badge.

  • Patent number: 8395507
    Abstract: In one embodiment the present invention includes a radio frequency identification (RFID) system with a shorting loop. The shorting loop at least partially surrounds the antenna. The shorting loop distorts the electromagnetic field generated by the antenna to improve the definition of the border of the read region of the antenna. In this manner, the RFID system provides more accurate discrimination between RFID tags inside the read region versus RFID tags outside the read region (i.e., improves the accuracy of determining that a particular RFID tag is inside the read region).

  • Patent number: 8390431
    Abstract: RFID reader systems, readers, components, software and methods cause RFID tags to backscatter a combination made from at least portions of a first code and a second code, without transmitting any commands in the interim. The first and/or second codes may include a tag response to a reader challenge. In a number of embodiments, a separate command does not have to be sent for reading the second code along with the first code, thereby saving time in inventorying the tags. Plus, the combination can enable reading tag codes during tag manufacturing that are not otherwise readily available to read in the field. In some embodiments, the combination may further include one or more error-checking codes.

    Abstract: Method for manufacturing a long-range RFID metallic product and structure thereof are provided so that UHF RFID skills can be smoothly applied on the various metallic products without interference. Electromagnetic waves radiated from a transmitter can be received by a metallic first antenna. With the resonance and induction generated by the resonance chamber located in the metallic first antenna and a second antenna of the electronic tag module patch, the signal generated can be transmitted to the RFID chip to achieve long-range reading and transmitting effects. Due to the breaking cutlines of the first rigid clip located on the second antenna of the electronic tag module patch, the second antenna of the electronic tag module patch is damaged when removing the electronic tag module patch from the metallic first antenna by tearing along the breaking cutlines of the first rigid clip, thereby preventing the RFID from being duplicated.

  • Patent number: 8344958
    Abstract: The invention relates to a secured document in the form of a booklet of at least one sheet which may be folded about a folding axis, the document having a transponder with an electronic chip provided with a memory for storing data and a transponder antenna. The document also includes a foldable amplifier antenna, distinct from the transponder antenna and arranged on the document such that, when the same is open, the amplifier antenna amplifies the electromagnetic flux received by the transponder antenna to permit communication of the document with a remote reader and, in the closed position of the document, the amplifier antenna reduces the electromagnetic flux received by the transponder antenna beneath a minimum threshold permitting communication of the electronic chip with a remote reader.

  • Patent number: 8325046
    Abstract: A radio frequency identification (RFID) system includes a plurality of RFID tags and a reader-writer. Each of the plurality of RFID tags has a tag antenna and a tag circuit that stores identification information. The reader-writer includes a first transceiver that reads the identification information of the plurality of RFID tags using an antenna. In this regard, the first transceiver transmits a reading command via the antenna for reading the identification information of the plurality of RFID tags. When the first transceiver does not read the identification information from one of the plurality of RFID tags due to an occurrence of a reading error in the first transceiver, the reader-writer adds reading error information, which indicates the occurrence of the reading error, to the next reading command to be transmitted from the first transceiver via the antenna.
