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.

An object name system (ONS) for locating one or more servers associated with an Electronic Product Code (EPC) is described. The system utilizes translation format strings to translate an EPC to an EPC domain prefix. The ONS server matches the EPC number to the address of a second server which has extensive information about the product. The second server recognizes the incoming EPC's as belonging to a particular object or service.

Methods and a computer program product for deriving temperature information with respect to surfaces within a scene that is imaged radiometrically. A time sequence of radiometric data is acquired in frames viewed from distinct angles. A three-dimensional structure of the scene is derived, allowing viewing angles and distances to the imaged surfaces to be inferred. Normalized surface areas of the imaged surfaces are calculated based on the inferred viewing angles and emissivities of the imaged surfaces are corrected accordingly. Corrections also account for background radiation impinging on the imaged surfaces. The radiometric data are converted to a perceptible temperature map of the imaged surfaces.

Methods and a computer program product for deriving a super-resolution image of a physical object, the super-resolution image characterized by a resolution exceeding a “camera imaging resolution” associated with each of a sequence of lower-resolution images of the physical object. The sequence of images of the physical object is obtained at a plurality of relative displacements with respect to the object. An offset is passively associated with each of the plurality of images to derive effective camera movement, allowing for calculation of a kinetic point spread function on the basis of the effective camera movement. The image sequence is deconvolved, using the kinetic point spread function, to solve for a high-resolution image. Various applications such as portable cameras and infrared imaging for energy conservation are described.

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. By including optional filters and queues in the EMS, the EMS can be configured as desired.

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.

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.
