Abstract: A system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) coupled to the EMS, the RIED for storing event information gathered by the EMS and a task management system (TMS) for ensuring that the RIED is updated by one transaction at a time. With this particular arrangement, a system for managing a large number of real-time events is provided. In one embodiment, the control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and/or temporally from an adjacent level in the hierarchy. This approach results in an intelligent network and also lends itself to scalability.

Abstract: A system and method for providing the capability of peeling thin polymer films from a substrate is provided. Generally, the method contains the steps of: providing a substrate having a top surface and a bottom surface; placing a peel initiator on the top surface; applying a polymer on the top surface of the substrate and a top surface of the peel initiator; curing the polymer, resulting in a thin-polymer film; and peeling the peel initiator from the substrate, thereby removing the thin-polymer film from the top surface of the substrate.

Abstract: In accordance with the present invention, a radio frequency identification (RFID) tag for use with an RFID system which includes one or more RFID tag readers, includes a tag communication device adapted to communicate with each of the one or more tag readers, a one-way hash function stored on the RFID tag, and a memory having stored therein a metaID. The tags may be locked and unlocked. The system includes a reader and a database. The system communicates with the tags via a forward channel and a backward channel. The present invention can singulate one tag from several responding tags and acquire the ID for the singulated tag.

Abstract: This invention relates to security protocols for RFID systems. Systems and methods are presented to protect the system from hackers attempting to compromise the RFID system. Also, methods and systems for improving RFID security are disclosed. The systems utilize mechanisms to determine the authenticity of the RFID tags used in such systems. The systems and methods also reduce unauthorized access to the RFID system. A system and method to make tags more difficult to compromise or counterfeit is also described.

Abstract: Systems and methods of using RFID tags and a mobile RFID reader device for determining a geographic position of assets within a prescribed region is provided. A method of inferring the geometric location of assets within a prescribed region comprises the steps of moving a mobile RFID reader through said prescribed region; wirelessly detecting, by the mobile RFID reader, a first RFID location transponder while moving through said prescribed region; wirelessly detecting, by the mobile RFID reader, at least one RFID asset tracking transponder while moving through said prescribed region; wirelessly detecting, by the mobile RFID reader, a second RFID location transponder while moving through said prescribed region; and determining the geographic location of assets associated with said at least one detected RFID asset tracking transponder based upon said detected first and second RFID location transponders and a known position and identification code of said first and second RFID location transponders.

Abstract: In one embodiment, a central data repository stores product code information. The central data repository can receive permissions from providers of the produce code information. The permissions can indicate whether the product code information can be provided to a third party.

Abstract: The present invention provides various techniques to improve the security of data transmissions in RFID systems. Systems and methods for constructing more secure RFID tags, readers, and servers are disclosed enabling individuals to minimize privacy exposure while taking care to avoid needlessly overcomplicating the user's RFID transactions.

Abstract: A method and system are provided for controlling the simulated interfacing of a controlled first body, for example a tool, with a second body while providing haptic feedback to a user on such interfacing. Selected representations of the first and second bodies are stored in a memory of a processing apparatus and are used by such apparatus to control simulated movement of the first body relative to the second body in response to a user controlled haptic interface device. Collisions between the first and second body are detected, including the position on each body of each collision, the direction of the collision and the force of the collision, and this information is converted for each collision into a force vector on the first body which is fed back as a corresponding force vector to the interface device, and thus to the user. A feature of the invention is storing a point cloud representation of at least one of the bodies, which point cloud representation is utilized in the simulations.

Abstract: A computer based virtual reality trading system for trading financial products such as commodities and stocks uses a server based system for generating a virtual trading floor to simulate an exchange. Traders use local PC's to direct their individual avatars interactively on the virtual trading floor, using hand and voice signals similar to a non-virtual exchange. This allows an exchange to be de-coupled from its physical geographic location as traders in diverse locations can interact on the virtual trading floor. The system enables accurate tracking for audit of the trade activity and simplified trade clearing, while retaining the dynamics of a non-virtual exchange.
