International Classification:

G08B 1314

US Classification:

3405721, 3405724, 3405727, 3405728, 340 101

Abstract:

A method for using multi-functional RFID tag assemblies, passive repeater systems and modular antenna systems. One embodiment comprises a method for communicating with an RFID tag by providing a passive loop modular antenna system, moving the RFID tag through a field related to the modular antenna system and transmitting energy through the antenna to communicate with the RFID tag. In a further embodiment, the RFID tag includes a passive loop in proximity with the RFID tag to improve the signals received and transmitted by the tag. In another embodiment, the RFID tag is removeably attached to a product container having a product therein and adapted to be removed from the container and re-attached to the product or a second container.

Appl. No.:

12/637299

Inventors:

Hao Su - Cupertino CA, US
Mark Nicholson - San Mateo CA, US

Assignee:

Juniper Networks Inc. - Sunnyvale CA

International Classification:

H04L 12/26

US Classification:

370244, 370249, 370250

Abstract:

A switch fabric for a modular router may be tested without connecting the switch fabric portion of the router to the other modular portions of the router. The switch fabric may generate test data units and insert the test data units into one or more elements of the switch fabric. The switch fabric may operate with the inserted test data units. A control component may receive data units from the switch fabric after operation of the switch fabric and analyze the received data units to determine whether the received data units correspond to the inserted test data units.
