IPC: G06F17/00
Filed: 2006-01-20
Abstract: The apparatus and methods disclosed herein relate to diagnosis of disease through the detection of signals from portions of a body. The signals may be acoustic signals, which can be used to diagnose the presence, severity and/or location of occlusions in arteries, such as the coronary arteries. The signals may be detected through noninvasive methods such as, for example, passive reception. Such methods can avoid many of the problems associated with invasive angiogram and angioplasty procedures. The apparatus and methods described herein are not limited to use for diagnosing occlusions in the coronary arteries, but can be used for a wide variety of biomedical diagnosis in human and nonhuman animals.

Title: Method and system integrating thermal oil recovery and bitumen mining for thermal efficiency
Inventor: SPEIRS BRIAN C
IPC: E21C37/16
Filed: 2007-08-17
Abstract: Thermal oil recovery operations, such as SAGD, result in waste heat that is typically released to the environment. Bitumen mining operations require heat input for heating fluids used in the mining process. A method and system of recovering heat from a thermal recovery operation for use in bitumen mining operation is described. A heated donor fluid from a thermal recovery operation is used to heat an acceptor fluid for use in bitumen mining via proximal heat exchange using a power cycle or heat exchange module, such as an ammonia and water based Kalina® Cycle. By utilizing waste heat from thermal recovery operations to heat fluids used in bitumen mining, thermal efficiencies are realized.

Patent CA-2610420-A1 (CA)
Inventor: DANA YOSSI
IPC: F16K15/02
Filed: 2006-06-14
Abstract: The present invention relates to a magnetic flow controller which transforms a slow reduction in pressure of fluid flow over time to a measurable fluid flow.  Once a threshold pressure differential is reached, a flow passage through the flow controller opens rapidly to a relatively large opening, thereby generating a volume of fluid at high flux flowing through the passage, particularly to permit the measurement of the volume of fluid in a conventional flow meter. The device of the present invention integrates this low flux and transforms it to a measurable fluid flux, so that the fluid can be measured by the fluid meter within its optimum error range.This is accomplished while maintaining a pressure drop in the flow meter which is within the permitted standards. Thus, the invention provides relatively sharp shifts between substantially high flux flow and no flow, in a pulse-like manner.

Title: Yeast-leavened refrigerated dough products
Inventor: DOMINGUES DAVID J
IPC: A21D8/04
Filed: 1994-03-04
Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. The dough's composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast or by inactivating the yeast at high temperatures. Dough compositions made in accordance with the invention are capable of being leavened at elevated temperatures, yet stored in a sealed container at refrigeration temperatures for extended periods of time.  In a preferred embodiment the yeast used in the dough is substantially incapable of fermenting carbohydrates native to the dough and a predetermined quantity of a non--native carbohydrate fermentable by the yeast (e.g. galactose) is added to the dough to provide the desired amount of proofing. A diploid yeast is further provided with the further property of being inactive at low temperature.

Patent CA-2627310-A1 (CA)
Inventor: SEMPERE JEAN-CHRISTOPHE
IPC: E21B49/00
Filed: 2006-09-12
Abstract: Method for making a probabilistic determination of total seal capacity for a hydrocarbon trap, simultaneously considering both capillary entry pressure and mechanical seal capacity, and where capillary entry pressure is estimated by relating it directly to the buoyancy pressure applied by the hydrocarbon column to the top seal. The method thus considers the substantial uncertainty associated with input parameters, which uncertainty limits the utility of such analyses for robust hydrocarbon column height and fluid contact predictions.  The method disclosed for estimating seal capillary entry pressure, the requisite input parameter for capillary seal capacity analysis, by inverting trap parameters avoids the need for direct measurement by mercury injection capillary capacity tests on small pieces of rock, which test results often are not available for all desired locations nor are they necessarily representative of adjacent rocks in the seal.

Title: Method and system for updating a broadcast segment recognition database
Inventor: DUNN STEPHEN M
IPC: H04H60/35
Filed: 1993-04-30
Abstract: Broadcast segment recognition systems and methods are provided in which a signature representing a monitored broadcast segment is compared with broadcast segment signatures in a data base representing known broadcast segments to determine whether a match exists. Criteria for determining the validity of such a match are provided. In one aspect, signatures representing audio broadcast signals are formed by comparing temporally displaced portions of respective frequency band values within plural frequency bands of the broadcast audio signal. Systems and methods are provided for producing signatures representing intervals of a video signal which compensate for shifts in an edge of a picture represented by the video signal. In addition, signatures characterizing respective intervals of a broadcast signal exhibiting correlation are produced by generating a difference vector for each respective interval and carrying out vector transformations of the different vectors to reduce such correlation. Moreover, signatures characterizing intervals of a video signal are produced with corresponding mask words representing reliability of values comprising the signature.  Mask words of first and second signatures thus formed representing different portions of the video signal displaced from one another are compared to establish the values of the mask word.
