Title: Casing expansion and formation compression for permeability plane orientation
Inventor: SCHULTZ ROGER L
IPC: E21B29/00
Filed: 2007-08-03
Abstract: Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.

Abstract: Un support lisible par ordinateur comprend des instructions exécutables pour comparer des bases de données. Les instructions exécutables sont configurées en vue d'identifier le moment où un segment d'une première base de données est conditionnellement hors synchronisation avec un segment correspondant pour établir un état conditionnellement hors synchronisation, en un premier temps. Des instructions exécutables permettent une période de latence après le premier temps, période durant laquelle des changements sont faits dans la première base de données et dans la seconde base de données. Des instructions exécutables déterminent également, après la période de latence, si le segment de la première base de données est en synchronisation avec le segment correspondant de la seconde base de données. Des instructions exécutables fournissent également une table de resynchronisation qui est utilisée, par un mécanisme de réplication, pour apporter des lignes asynchrones dans une synchronisation.

Title: Method for incorporating identifying error information into a data carrying disc
Inventor: HEYLEN RICHARD A A
IPC: G11B7/0037
Filed: 1999-09-29
Abstract: The manufacturing process for a data carrying disc, such as a CD, begins with the production of a master, and in the physical manufacturing process of a master, variations are introduced which give the master distinctive physical characteristics and cause errors in the data. The master is used to form generations of discs, and the physical characteristics of the master are passed on down the generations. A group of discs manufactured from the same source consistently exhibit the physical characteristics of the master, and those physical characteristics can be used as a signature for identifying the disc. To determine the provenance of a data carrying disc, uncorrected data is read from the disc. Information about errors is extracted from the data read. The error information may then be compared with a stored list of characteristic error information to determine whether the data carrying disc is genuine. The error information extracted is representative of errors arising from the physical manufacturing process.

Title: High strength and sagging resistant fin material
Inventor: TANGEN STIAN
IPC: C21D8/02
Filed: 2007-10-11
Abstract: The present invention provides a method for producing AIMn strip or sheet for making components by brazing, as well as the products obtained by said method. In particular this method is related to fin materials used in heat exchangers. The fins can be delivered with or without a cladding depending on application. Rolling slabs are produced from a melt which contains 0.3-1.5% Si, <=0.5% Fe, <=0.3% Cu, 1.0-2.0% Mn, <=0.5% Mg, <=4.0% Zn, <=0.3% each of elements from group IVb, Vb, or VIb elements, and unavoidable impurity elements, as well as aluminium as the remainder in which the rolling slabs prior to hot rolling are preheated at a preheating temperature of less than 550°C, preferably between 400 and 520°C, more preferably between 450 and 520°C to control the number and size of dispersoid particles, and the preheated rolling slab is hot rolled into a hot strip. The strip is thereafter cold rolled into a strip with a total reduction of at least 90%, and the cold rolled strip is heat treated to obtain a 0.2% proof stress value that is 50 - 90% of its proof stress value in the as cold rolled condition to a proof stress value in the range between 100 and 200 MPa. The strip may alternatively be produced by twin- roll strip casting. The composition of the melt tailors the microstructure development during the complete processing to give the desired post braze properties and performance during brazing in combination with adequate delivery properties of the strip. In particular the high post braze strength combined with a good sagging resistance and low susceptibility to liquid core penetration during brazing, as well as a relatively good formability in the delivery condition prior to fin forming.

Title: Trustworthy multi-objective structural synthesis and expert knowledge extraction with application to analog circuit design
Inventor: MCCONAGHY TRENT
IPC: G06F17/50
Filed: 2008-05-16
Abstract: A system that does trustworthy multi-objective structural synthesis of analog circuits, and extracts expert analog circuit knowledge from the resulting tradeoffs. The system defines a space of thousands of possible topologies via a hierarchically organized combination of designer-trusted analog building blocks, so that unlike open-ended synthesis approaches, the resulting topologies are guaranteed trustworthy. The system can perform a search that is a multi-objective evolutionary algorithm that uses an age-layered population structure to balance exploration vs. exploitation, with operators that make the search space a hybrid between vector-based and tree-based representations. A scheme employing average ranking on Pareto fronts is used to handle a high number of objectives. Good initial topology sizings are quickly generated via multi-gate constraint satisfaction. To explicitly capture expert analog design knowledge, data mining is employed on the sized circuits to:  automatically generate a decision tree for navigating from performance specifications to topology choice, to do global nonlinear sensitivity analysis, and to generate analytical models of performance tradeoffs. Experiments are performed by simultaneously searching across thousands of different one- and two-stage op amp topologies, followed by data-mining-based topology knowledge extraction.

Patent CA-2636442-A1 (CA)
Inventor: FACCIN MARCO
IPC: H05B41/298
Filed: 2007-01-22
Abstract: A device for protecting an electronic converter, e.g.for halogen lamps, includes a comparator (10) having an output (Vo) as well as non-inverting (14) and inverting (12) inputs for receiving a first input signal (Vi(P)) indicative of the load applied to the converter and a second input signal (Vref(T°)) indicative of the temperature of the converter. The comparator (10) is in a non-inverting Schmitt-trigger configuration having an input-output characteristic with hysteresis. Consequently, the output (Vo) is switched from a first value (Vol) to a second value (Voh) to switch off the electronic converter as the first input signal (Vi(P)) exceeds a first threshold value (VT1). The output (Vo) is switched back from the second value (Voh) to the first value (Vo1) to restart the electronic converter when the first input signal (Vi(P)) falls below a second threshold value (VT2). The second threshold value (VT2) is lower than the first threshold value (VT1), and both threshold values (VT1, VT2) are a function of the signal (Vref(T°)) indicative of the temperature of the converter. The converter is thus protected against both current overloads and temperature overloads.
