| 20080235937 | WAVE ANTENNA WIRELESS COMMUNICATION DEVICE AND METHOD - A wireless communication device coupled to a wave antenna that provides greater increased durability and impedance matching. The wave antenna is a conductor that is bent in alternating sections to form peaks and valleys. The wireless communication device is coupled to the wave antenna to provide wireless communication with other communication devices, such as an interrogation reader. The wireless communication device and wave antenna may be placed on objects, goods, or other articles of manufacture that are subject to forces such that the wave antenna may be stretched or compressed during the manufacture and/or use of such object, good or article of manufacture. The wave antenna, because of its bent structure, is capable of stretching and compressing more easily than other structures, reducing the wireless communication device's susceptibility to damage or breaks that might render the wireless communication device coupled to the wave antenna unable to properly communicate information wirelessly. | 10-02-2008 |

| 20100259392 | MERCHANDISE SECURITY KIT - A merchandise security kit includes a tag body, a first tack adapted to be removably attached to the tag body to form a first reusable hard tag that is limited to electronic article surveillance (EAS) capabilities, and a second tack adapted to be removably attached to the tag body to form a second reusable hard tag that is provided with both EAS and radio frequency identification (RFID) capabilities. The tag body comprises a security inlay that is disposed within a protective casing, the security inlay including an antenna and an EAS marker. The second tack comprises an enlarged head, a sharpened pin connected to the head and an integrated circuit (IC) chip embedded within the head. With the second tack attached to the tag body, the IC chip either conductively or reactively couples to the antenna in the tag body to provide the second hard tag with its RFID capabilities. | 10-14-2010 |

| 20090108993 | RFID TAGS WITH MODIFIABLE OPERATING PARAMETERS - A radio-frequency identification (RFID) tag includes a facestock and a liner. The facestock includes an RFID circuit with an operating parameter, and the liner is releasably attached to the facestock such that when the liner is detached from the facestock, the operating parameter of the RFID circuit is desirably modified. The RFID tag may be configured so that the operating parameter that is modified is, for example, a read range or a propagation direction. The RFID circuit may include an RFID chip and an antenna, and the liner may include an electrical element that modifies a read range of the RFID circuit when the liner is attached to the facestock. More specifically, the electrical element may electrically couple with the antenna when the liner is attached to the facestock, thereby reducing the read range of the circuit. When the liner is removed, the antenna is decoupled from the electrical element and thereby enabled to operate at another read range, i.e., a specified operating range. Alternatively, the electrical element may couple with the antenna of the RFID circuit so that energy is propagated from the element in a direction that is orthogonal to a normal direction of propagation of the antenna. | 04-30-2009 |
| 20090205515 | RFID TAG THAT PROVIDES A FLAT PRINT AREA AND A PINCH THAT ENABLES THE SAME - A radio-frequency identification (RFID) tag includes a face stock and an RFID device. The face stock has a printable side and an inlay side, with the RFID device mounted to the inlay side. A layer of adhesive is coated on the inlay side of the face stock. A liner is releasably adhered to the layer of adhesive and includes a relief area that accommodates for defection of the RFID device. The accommodation of the thickness of the RFID device results in a tag that has a substantially uniform printable surface. Accordingly, when passing through a printer, the printable surface is maintained substantially flat or linear at the print head of the printer, thereby minimizing jamming and enhancing printability. A pinch roller for a printer also accommodates for deflection of the RFID tag by providing a deformable section along a length thereof the body that has a greater resiliency than the rest of the body. At the location of the RFID device, the layer of adhesive may also include a blank that is substantially free of adhesive for accommodating the RFID device. | 08-20-2009 |
| 20090219137 | Variable frequency tag - An antenna assembly is operative for receiving interrogating radiation at a variable frequency tag and generating a corresponding received signal, and for receiving a signature signal and radiating corresponding response radiation. A logic unit is operative for receiving the received signal and outputting the signature signal in response, the signature signal including a signature code for use in identifying the tag. A voltage controlled oscillator is operative for controlling a rate at which the signature code is output; and a power supply is operative for providing an electrical potential difference for energizing the tag. The voltage controlled oscillator is operable to output the signature code at a rate which is governed by the magnitude of the received signal. | 09-03-2009 |
| 20090219138 | Reader interfacing device - A reader interfacing device is operative for providing a communication path between a tag or smart label reader configured to emit and receive interrogating radiation suitable for interrogating tags or smart labels at a first radiation frequency; and a remote tag or smart label is configured to be interrogated using radiation of a second frequency, the first frequency and the second frequency being mutually different by at least an order of magnitude, and the reader being operable to communicate through the device to the remote tag or smart label. The device includes a power supply for converting interrogating radiation received at the device from the reader to generate power supply potentials for powering the device. Moreover, the device is mutually magnetically coupled to the reader for receiving the interrogating radiation therefrom and for providing a modulated load thereto for communicating back to the reader. In order to achieve such magnetic coupling, the device including a loop antenna for magnetically coupling to a corresponding loop antenna of the reader. The device provides, for example, the advantage that the reader can conform to a standard ISO 15693 and the device enables remote tags and smart labels not conforming to the standard to communicate with the reader. | 09-03-2009 |
