20090021379 | SYSTEMS AND METHODS FOR A RFID ENABLED METAL LICENSE PLATE - In the embodiments described herein, a RFID enabled license plate is constructed by using the license plate, or a retro-reflective layer formed thereon as part of the resonator configured to transmit signals generated by and RFID chip integrated with the license plate. Such an RFID enabled license plate can include a metal license plate with a slot formed in the metal license plate, and a RFID tag module positioned in the slot. The RFID tag module can include a chip and a loop, and the loop can be coupled with the metal license plate, e.g., via inductive or conductive coupling. In this manner, the metal license plate can be configured to act as a resonator providing increased performance. | 01-22-2009 |
20090122986 | SYSTEMS AND METHODS FOR PREVENTING TRANSMITTED CRYPTOGRAPHIC PARAMETERS FROM COMPROMISING PRIVACY - A method for secure cryptographic communication comprises transmitting information that identifies a group key from a first device to a second device. The method further comprises, in the first device, using the group key to encrypt an input vector, transmitting the encrypted input vector, encrypting privacy-sensitive information using a device key, an encryption algorithm, and the input vector, and transmitting the encrypted privacy-sensitive information to the second device. | 05-14-2009 |
20090251293 | SYSTEMS AND METHODS FOR MANAGING INVENTORY OF ITEMS HELD IN A CABINET USING RADIO FREQUENCY IDENTIFICATION (RFID) - A RFID cabinet comprises a cabinet structure and one or more drawers or shelves. Chambers are formed within the cabinet to house the one or more drawers or shelves. An RFID scanner is configured to scan items tagged with RFID tags in the chambers via one or more antennas. The antennas can include transmit and receive antennas or antennas configured to perform both transmit and receive functions. The drawers can have a access cover, or lid that can be controlled so as to control access to the drawer. The scanner can be configured to perform inventory control for the tagged items. | 10-08-2009 |
