Abstract: A current state of an item being tracked by an item-tracking system may be determined using prior state information about the item. To ensure proper temporal order of the state information, software events triggered by physical events associated with the item are received from a reader at an event interpretation system. A database or queue within the event interpretation system holds the software events for a delay time determined by a maximum transmission delay time of the software events. A sorter within the event interpretation system orders the software events relative to one another so as to correspond to an order of the physical events. An association model of the event interpretation system may determine state information related to the item for storage in a state information database. Accordingly, system exceptions in the item tracking system may be reduced, and an accuracy and reliability of the system may be improved.

Abstract: Systems, methods and computer program products, implementing techniques for automatic data acquisition and the real-time display of automatically acquired data. A system implementing the techniques includes one or more automatic data acquisition devices that emit data; and a data integration system that receives data from the automatic data acquisition devices and processes the data. The data integration system includes a display system for displaying the data to a user. The display system is operable to generate a graphical display and to update the graphical display automatically and only when new data from the automatic data acquisition devices is available. The display system is operable to update only affected parts of the graphical display but not necessarily the entire display.

Abstract: Methods and apparatus, including computer program products, for receiving constraint characterizing data applicable to a sensor network, receiving a logical representation of a requirements specification for the sensor network, and processing the constraint characterizing data and the logical representation of the requirements specification to generate a modular representation of the sensor network. The constraint characterizing data includes physical environment data, sensor constraint data, and application domain data. The modular representation of the sensor network defines sensor node placement and sensor distribution within the sensor network.

Abstract: In accordance with an exemplary embodiment of the invention, a substrate of a first conductivity type silicon is provided. A substrate cap region of the first conductivity type silicon is formed such that a junction is formed between the substrate cap region and the substrate. A body region of a second conductivity type silicon is formed such that a junction is formed between the body region and the substrate cap region. A trench extending through at least the body region is then formed. A source region of the first conductivity type is then formed in an upper portion of the body region. An out-diffusion region of the first conductivity type is formed in a lower portion of the body region as a result of one or more temperature cycles such that a spacing between the source region and the out-diffusion region defines a channel length of the field effect transistor.

Abstract: A trenched field effect transistor is provided that includes (a) a semiconductor substrate, (b) a trench extending a predetermined depth into the semiconductor substrate, (c) a pair of doped source junctions, positioned on opposite sides of the trench, (d) a doped heavy body positioned adjacent each source junction on the opposite side of the source junction from the trench, the deepest portion of the heavy body extending less deeply into said semiconductor substrate than the predetermined depth of the trench, and (e) a doped well surrounding the heavy body beneath the heavy body.
