Abstract: An un-indexed, partitioned temporary table and an exchange table are used in the inferencing of semantic data in a relational database system. The exchange table has the same structure as a semantic data table storing the semantic data. In the inferencing process, a new partition is created in the semantic data table. Inference rules are executed on the semantic data table, and any newly inferred semantic data generated is added to the temporary table. Once no new data is generated, the inferred semantic data is copied from the temporary table into the exchange table. Indexes that are the same as indexes for the semantic data table are built for the exchange table. The indexed data in the exchange table is then exchanged into the new partition in the semantic data table. By use of the un-indexed, partitioned temporary table, incremental maintenance of indexes is avoided, thus allowing for greater efficiency.

Abstract: An ultrasound system visualizes shear wave propagation in real time by slowing down the propagation of the shear wave as seen by the ultrasound probe. The shear wave source propagates shear waves into the medium at a frequency ?. The ultrasound probe is vibrated by a vibrator at the frequency ????, where ?? is much smaller than ?. The wave propagation as seen by the ultrasound probe is slowed down by a factor ??/?. An appropriate value of ?? allows real-time visualization of the wave propagation. Variations include electronically producing a virtual vibration and the use of multiple shear wave sources.

Abstract: An apparatus, system and method for adaptively controlling a frame interval between ultrasound scanning frames of an ultrasound elasticity imaging scan. The system includes a transmitter for transmitting ultrasound beams to a subject during an ultrasound elasticity imaging scan, and a receiver for receiving ultrasound beam echoes from the subject responsive to transmitted ultrasound beams. The system also includes a processor for processing a plurality of the ultrasound beam echoes to determine a strain variation of the tissue undergoing strain, calculating a value for an ultrasound scanning frame interval adapted for imaging the tissue undergoing the determined strain variation, and setting the value of the ultrasound scanning frame interval for acquiring ultrasound elasticity images of the tissue undergoing the determined strain variation.

Abstract: A repository server that makes stored copies of Web-accessible documents available at times when the documents themselves are inaccessible via the Web, because the server the document is located on is unavailable, because the server has removed or renamed the document, or because the server has replaced the version of which the stored copy is a copy with a different version. A client of the repository server may register a document in the repository server. The repository server makes a copy of the registered document and returns a repository URL for the copy to the client. The repository URL may be used to fetch the copy from the repository URL. Registration further relates the stored copy to its document URL, to an identifier for the stored copy, to a fingerprint that is a condensed representation of the stored copy's content, and to a set of stored copies having similar content.

Abstract: This is an innovative Over-Current Protection device that uses a unique method of controlling the energy to a compact tripping solenoid of a mechanical circuit breaker mechanism to cut off power to an electric circuit whenever the load current exceeds a specified level. Unlike previous Over-Current Protection devices, this device also maintains independent levels or stages of over-current protection and is able to distinguish between stages via independent current detection circuits that define the operational characteristics of each over-current stage. The device includes a current sensing transformer, independent current-threshold detectors, time delay circuits and a random phase, energy-accumulating circuit which generates a controlled trigger-pulse to trip the compact tripping solenoid of the mechanical circuit breaker mechanism. This device is also designed to connect directly onto, and operate in conjunction with, an existing GFCI (Ground Fault Circuit Interrupter) module.

Abstract: A low current detector using magnetoresistive sensor is used in a ground fault detector that opens a current carrying circuit when an unbalanced or dangerous condition occurs in the circuit. The current circuit has windings wrapped around a toroidal member of magnetic material having a cross sectional gap. First magnetic flux lines induced in the toroidal member by the circuit project from the gap toward a permanent magnet having second emergent magnetic flux lines that bend the first flux lines in a flux line mesh zone when an unbalanced current exists in the current carrying circuit. The flux lines are non-existent in the gap of the toroidal member when the circuit is in a balanced or non-fault state. A magnetoresistive sensor is disposed in the mesh zone in a position producing a signal indicative of an unbalanced condition caused by a current fault. A circuit breaker, connected to flux sensor responds to the signal indicating an unbalanced condition by opening the circuit.

Abstract: Disclosed are stabilized unimolecular initiator compounds which are useful for initiating living radical polymerization of polymerizable hydrocarbons. The stabilized unimolecular initiator compounds are the reaction products of polymerization initiator radical-forming compounds, such as organo peroxides and azo compounds, and stable radical-forming compounds, wherein the polymerization initiator radicals are capable of initiating polymerization of polymerizable hydrocarbons and the stable radicals, alone, are not capable of initiating polymerization of hydrocarbons. An exemplary stabilized unimolecular initiator compound is 1-benzoylperoxy-2,2,6,6-tetramethyl-1-piperidine which is the reaction product of benzoyl peroxide, (BPO), and 2,2,6,6-tetramethyl-1-piperidineyloxy, (TEMPO).
