Abstract: An on-demand upgrade system and method for upgrading components of a distributed system is provided in which an upgrade notice is used.

Abstract: A real-time query processing system to locate and retrieve object data in a RFID network is presented. The object data can be located in any data stored on the network or may be data that is generated in response to the user request. The system is operated by a user-friendly web-based GUI that allows remote access by out-of-network computer systems. The real-time query processing system provides comprehensive and flexible searching of the RFID network using a simple interface that can be accessed from anywhere in the world. It enables an immediate and tailored response to supply chain and business management questions as they arise, and greatly facilitates management of the entire supply chain and the RFID network.

Abstract: A bidirectional radio frequency identification (RFID) network system and method are presented. The system allows users to configure, monitor, and manage different sensor devices by using a graphical user interface real-time. The reconfiguration is done through a network management computer at the top system level that receives user input, generates code images according to the user input, and appropriately routes the code images to sensor routers that directly control the sensors. If the system is multi-layered, some code images are also sent to the intermediate-level network management computers. The system allows users to not only monitor a business flow but react to problematic situations quickly by adjusting the workflow. The aspect-oriented nature of the system allows users to reconfigure the system based only the Functionality aspects without worrying about the Partitioning aspects (e.g., how the network and the sensors are physically connected).
