Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that allows a ring node to bridge user traffic in the case that no switch table entry is present for that traffic. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.

This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link where the unidirectional break is not sensed as an OPER DOWN state.

The present invention is a method and system for estimating liability reserve amounts for incurred but not yet paid (EBNP) insurance claims by means of projecting paid claims (either gross or per exposure) by lag time based on adjusted average monthly paid amounts in historical data. Two versions of this method are disclosed, one which assumes that future paid claim amounts are independent of claims incurred and already paid, and the other which assumes that future paid claims are correlated with cumulative incurred and paid claims through the valuation date. Both versions have been shown to give significantly more accurate results than the traditional Completion Factor and Incurred claims Methods when applied to sets of real data.

Light reactive deposition can be adapted effectively for the deposition of one or more electrochemical cell components. In particular, electrodes, electrolytes, electrical interconnects can be deposited form a reactive flow. In some embodiments, the reactive flow comprises a reactant stream that intersects a light beam to drive a reaction within a light reactive zone to produce product that is deposited on a substrate. The approach is extremely versatile for the production of a range of compositions that are useful in electrochemical cells and fuel cell, in particular. The properties of the materials, including the density and porosity can be adjusted based on the deposition properties and any subsequent processing including, for example, heat treatments.

There is a method of manufacturing a cast collimator that includes pre-heating a mold, filing the mold with material in a liquid phase, and simultaneously applying vacuum, heat and vibration to the mold until the material reaches a substantially solid phase.

A porous structure having a plurality of bonded sheets each sheet having at least one aperture that partially overlaps an aperture of at least one other sheet. A method of producing a porous structure including stacking a plurality of sheets each sheet having a multiplicity of apertures, and bonding each sheet to its adjoining sheet. An open-pore network structure having a multiplicity of sheets each having a repeatable pattern. At least a portion of each sheet is bonded to the web of an adjacent sheet. The porous area of at least one of the sheets is askew to the porous area of at least another of the sheets. An open-pore structure having a multiplicity of bonded sheets, each sheet having a repeatable pattern defining a multiplicity of perforations, and a plurality of apertures defined by the repeatable pattern, the apertures extending through the perforations of at least two adjacent plates.
摘要:
An apparatus for synchronized operation of a plurality of EAS systems. The system includes two or more EAS systems. Each EAS system has a receiver for receiving the same RF synchronization signal sent from a remote source, a transmitter for transmitting a marker exciter pulse and an exciter pulse receiver. The transmitter and exciter pulse receiver of each of the EAS systems are selectively enabled a predetermined time after receiving the RF synchronization signal so that all EAS systems in a localized area can be synchronized with one another.
摘要:
A dental instrument for endodontic applications comprising an elongated shaft having a proximal end and a reduced diameter distal end and a tapered working portion extending from the proximal to the distal end, the working portion having at least one helicoidal cutting/scraping edge, the taper of the shaft working portion being defined by an initial relatively large radius of concavity at the distal end and of continually reduced radius of concavity terminating in a final relatively small radius of concavity at the proximal end. In one embodiment the radii of concavity varies with substantial elliptical conformity.

A system and method for integrating point of sale (POS) data with electronic article surveillance (EAS) data, comprising a general-purpose computer for receiving and processing POS and EAS data is disclosed. The system and method preferable comprise reporting analyzed and collated data to a user.
摘要:
Textured surface having micro recesses such that the outer surface overhangs the micro recesses. Embodiments of the textured surface include sharp edges for promoting bone deposition and growth within the micro recesses, protrusions of varying depth from the surface that include overhangs, and micro recesses that are at least partially defined by complex ellipsoids.
