| 20090051539 | RFID TAG HAVING ANTENNA WITH CO-PLANAR RADIATION PATTERN - An radio frequency identification (“RFID”) system and RFID tag that include a substrate body having a surface where the substrate body defines a plane of the tag, an RFID integrated circuit disposed on the surface of the substrate body, and an antenna that has an antenna pattern, which is disposed on the substrate body and in electrical communication with the RFID integrated circuit, the antenna generating a radiation pattern with maximum gain along an axis that is substantially coplanar with the tag. The antenna can include a first antenna portion and a second antenna portion, the first antenna portion having a first antenna end and a second antenna end, the first antenna end of the first antenna portion in electrical communication with the RFID integrated circuit and the first antenna portion forming an antenna pattern in a counterclockwise direction, and the second antenna portion having a first antenna end and a second antenna end, the first antenna end of the second antenna portion in electrical communication with the RFID integrated circuit and the second antenna portion forming an antenna pattern in a clockwise direction. | 02-26-2009 |
| 20090205381 | Identification/surveillance device with removable tack button - An identification/surveillance device including a tag portion and a tack. The tack includes a button and a pin having a dull end and a sharp end. The identification/surveillance device is secured to an article to be identified/surveilled by inserting the pin through the article and engaging the pin with the tag portion. The dull end of the pin is releasably engaged with either the button or the tag portion such that when the identification/surveillance device is removed from the article the sharp end of the pin remains engaged with either the tag portion or the button and only the dull end of the pin is exposed. | 08-20-2009 |
| 20100148969 | OPTIMIZATION OF THE FIELD PROFILE ON A HIGH FIELD STRENGTH MAGNETIC DETACHER - A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet. | 06-17-2010 |
