| Number | Title | Issue Date |
| 7916028 | RFID inventory monitor Moving a mobile RFID reader with an area in a systemic manner to do non-inventory tasks, while doing the non-inventory tasks, integrating RFID tags associated with inventory, and updating a database with the inventory information obtained from the RFID tags. ... | 03/29/2011 |
| 7884719 | Radio frequency identification (RFID) tag lamination process An antenna web can include an RFID antenna on a first side of a substrate. An adhesive can be laminated on a second side of the substrate. The antenna web can then be cut into individual segments for use in constructing an RFID label. ... | 02/08/2011 |
| 7859415 | RFID based identification device A RFID-based identification device comprising a first RFID antenna; and a second RFID antenna, wherein the first and second RFID antennas are in a first arrangement, the resonant frequencies of the antennas are away from an interrogation frequency such that no ident... | 12/28/2010 |
| 7791483 | Game system using RFID tags A game can comprise a board with multiple RFID antennas and a game piece with a RFID antenna. When one of the multiple RFID antennas is adjacent to the RFID antenna in the game piece, the response characteristics of these RFID antennas can change so that the positio... | 09/07/2010 |
| 7674649 | Radio frequency identification (RFID) tag lamination process using liner A method of constructing an RFID unit can include using a protective layer to hold an integrated circuit chip module to a substrate layer with an antenna unit while a conductive adhesive has not yet fully set. ... | 03/09/2010 |
| 7639184 | Method for forming radio frequency antenna A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate. The antenna coil pattern is formed using a conductive ink which is patterned on the substrate. The conductive ink is cur... | 12/29/2009 |
| 7456752 | Radio frequency identification sensor for fluid level A sensor can detect the presence of fluid by the changing of the response characteristics of an RLC circuit. A window in the sensor is used to position a short caused by the fluid. ... | 11/25/2008 |
| 7456506 | Radio frequency identification (RFID) tag lamination process using liner A method of constructing an RFID unit can include using a protective layer to hold an integrated circuit chip module to a substrate layer with an antenna unit while a conductive adhesive has not yet fully set. ... | 11/25/2008 |
| 7388542 | Method for an element using two resist layers A two resist layer process allows a seed layer to be used to electroplate a conductive layer of an element in a way that a portion of the seed layer can be removed. ... | 06/17/2008 |
| 7377447 | Tuned radio frequency identification (RFID) circuit used as a security device for wristbands and package security A tamper evident RFID circuit uses a fold section that forms a capacitive element when folded together. ... | 05/27/2008 |
| 7298331 | Method for forming radio frequency antenna A metalized circuit suitable for application as a radio frequency antenna is produced by forming an antenna coil pattern on a flexible substrate.
