20110206523 | WELDING PROCESS AND COMPONENT FORMED THEREBY - A process of fabricating a rotating component and a rotating component formed thereby. The rotating component has a rotational axis, at least one rim member, at least one disk member, and at least one airfoil member. The rim and disk members are welded together to define a first solid-state weld joint lying in a first plane that is not parallel to the rotational axis of the rotating component. The airfoil member is welded to the rim member to define a second solid-state weld joint lying in a second plane that is not parallel to the rotational axis of the rotating component. The rim member is located in a radially outward direction from the disk member, and the airfoil member is located in a radially outward direction from the rim member. | 08-25-2011 |

20090315716 | Identification band using serpentine paths to detect tampering - A tamper-resistant RFID wristband that becomes permanently disabled upon tampering. The wristband includes a plurality of holes for snugly securing the band to a wearer, an RFID circuit, and an electrically conductive loop disposed in the band. The RFID circuit and the conductive loop are electrically coupled to form a series circuit, severance of which disables the wristband. The electrically conductive loop includes a first layer and a second layer that are electrically isolated from one another, save for at least one electrical connection made preferably by a via at the end of the band distal from the antenna element. The first layer encircles the holes in a serpentine path on one layer of the band and the second layer encircles the holes in a complimentary serpentine path on a different layer of the band | 12-24-2009 |
20100012733 | Identification band using a conductive fastening for enhanced security and functionality - An identification device formed from a band of material and a non-reusable tamper-resistant fastening arranged to join opposite end regions of the band. A Radio Frequency Identification (RFID) transponder is disposed in the band. The transponder includes and RFID circuit, such as may be formed on an integrated circuit (IC) chip, and an antenna. In the present invention, the tamper-resistant fastening serves additional functions beyond securing the opposite end regions of the band together. Namely, the fastening can be made of a conductive material and designed to create electrical continuity between multiple conductors to enable or disable certain circuit functionality. In one variation, this continuity allows the excess tail portion of the wristband to be cut without disrupting circuit functionality. In another variation, the fastening mechanism is designed to crimp conductors together. In yet another embodiment, the RFID circuit itself is wholly or partially formed within the fastening mechanism to better protect and support the circuit, as well as to make it more difficult to defeat the tamper-resistant functionality of the device. | 01-21-2010 |
20100095522 | Method of manufacture of an identification wristband construction - A method of manufacture of a wristband includes the steps of providing a bottom substrate. First circuit elements are deposited on the bottom substrate. A dielectric material is deposited at predetermined areas on the bottom substrate. A remainder of the circuit is deposited on the bottom substrate and dielectric materials. A transponder chip is secured to the bottom substrate to form a transponder. A second substrate is affixed to the bottom substrate such that the dielectric material and transponder are disposed between the bottom substrate and second substrate. | 04-22-2010 |

20090048936 | Method and system for RFID transaction integrity utilizing an EEPROM - A method for purchasing goods in a cashless operation utilizing an RFID apparatus is provided. The RFID apparatus includes an EEPROM, the EEPROM being formatted to include a first group of data blocks and a second group of data blocks. Transaction data is stored in the first group of data blocks. When placing an order for goods or services, an RFID scanner scans the EEPROM. The RFID scanner reads a start block pointer value from a data block of the EEPROM. The pointer value corresponds to the address of the last written of the first group of data blocks or second group of data blocks. Data is then read from the last written group of data blocks. As the transaction is processed, the transaction data is modified in accordance with a purchase order to create modified data. The modified data is written to the second group of data blocks. Once it is determined that the writing to the second group of data blocks is successful, the pointer value stored in the EEPROM is changed to indicate the second group of data blocks. | 02-19-2009 |
