- RFID TRANSCEIVER SENSITIVITY FOCUSING SYSTEM
INCOM CORPORATION
August 14, 2008
Shielding of a particular material and geometry is interposed between a radio frequency identification ('RFID') antenna transceiver and a zone to be monitored by the antenna. The shielding has an aperture therein that to some extent defines a degree of focusing of the radio frequency ('RF') field associated with the antenna. RFDD tags having appropriate RFID circuitry are only detected by the antenna when they pass within the focused RF field. The shielding is formed of a thin metalized plastic material, such as film used in forming anti-static material for storage of sensitive electronics. One particular formulation is primarily polyethylene film with an aluminum coating or layer thereon. - ITEM LEVEL INVENTORY WITH A RADIO FREQUENCY IDENTIFICATION (RFID) SYSTEM
SENSORMATIC ELECTRONICS CORPORATION
August 14, 2008
A radio frequency identification (RFID) system for item level inventory and a method for performing an RFID item level inventory may be provided. The method may include selectively controlling with an RF signal each of a plurality of multiplexers connected to a plurality of local antennas and selectively enabling with an RF signal the plurality of local antennas using the plurality of multiplexers to perform RFID interrogation on a plurality of RFID tags. The method further may include acquiring inventory information based on the RFID interrogation. - DROPLET COLLECTION DEVICES AND METHODS TO DETECT AND CONTROL AIRBORNE COMMUNICABLE DISEASES UTILIZING RFID

A filtering face mask that comprises: (a) a mask body; and (b) at least one diagnostic device for identifying whether the wearer of the mask is infected with a contagious disease. - RFID CARD CONTAINER AND RFID COMMUNICATION AUXILIARY SHEET
TAIYO INC.
August 14, 2008
Provided is an RFID card container which contains a plurality of RFID tags and permits only one desired RFID tag to start up to be readable and other RFIDs to be unreadable when magnetic field is applied from an RFID reader. An RFID communication auxiliary sheet is also provided. The RFID card container and the RFID communication auxiliary sheet are manufactured by using a board-like member having a magnetic material layer, a conductor layer and a gap layer. In the RFID card container and the communication auxiliary sheet, the board-like member is used to be arranged between a first RFID tag and a second RFID tag. When magnetic field is applied from the RFID reader positioned on the side of the first RFID tag, the first RFID tag starts up a... - HIERARCHICAL RFID
INTERNATIONAL BUSINESS MACHINES CORPORATION
August 14, 2008
An RFID tag is provided including an object ID and a counter. Such an RFID tag may be employed in an RFID tag system including a parent RFID tag having an object ID and a counter, a child RFID tag, and a reader/writer configured to read the object ID and the counter of the parent RFID tag, combine values of the object ID and the counter, and write the combined value to an object ID of the child RFID tag. - PHOTOVOLTAIC DEVICE COMPRISING AN RFID SAFETY DEVICE, AND METHOD FOR THE PRODUCTION THEREOF
SOLARTEC AG
August 14, 2008
The invention relates to photovoltaics for converting solar energy into electric energy, comprising at least one solar cell (25) fastened to a carrier plate (20), and at least one RFID tag (55) for storing identifying data of the photovoltaic device (10), wherein the RFID tag is an RFID tag (55) that is electrically insulated from the at least one solar cell (25). The invention further relates to a method for the production thereof. -
