Title: Acoustic echo cancellation
Inventor: REED MARTIN
IPC: G10L21/0232
Filed: 2000-05-18
Abstract: A multiple channel steered spatialised signal is generated from a signal input (12) modified according to respective spatialisation gain functions (g1, g2) to generate a plurality of audio channels (x1(t), x2(t)). An echo cancellation signal e(t) is applied to a return path (22) using a combined spatialisation and echo path estimate (h1, h2). The estimate is derived from the gain functions applied to the respective channels 14L, 14R. When the gain functions applied in the respective channels are changed, for instance to represent a different apparent position of the sound source (10), a new estimate (h1, h2) of the echo paths (h1, h2) is generated, based on a previous estimate of the echo path and on the new gain functions (g1, g2).

Patent CA-2380724-A1 (CA)
Inventor: MCARTHUR DON
IPC: B65D65/40
Filed: 2002-04-04
Abstract: A laminate for gum packaging is defined. The laminate includes a metal layer, a polymer layer, a paper layer, and an electron beam cured coating. The laminate provides as good or better barrier properties as a conventional laminate for gum packaging. However, the laminate has "reacted-in" slip agents in the electron beam cured coating, thereby avoiding the common problems of slip agent migration. Further, the laminate of the invention is more economical to produce than is the conventional laminate.
Patent CA-2384939-A1 (CA)
Inventor: SMITH GORDON M
IPC: F16K31/528
Filed: 2001-07-11
Abstract: In the stem set configuration for a double block and bleed plug valve, the improvement provides an operator (40) which can be significantly shorter and more compact than conventional operators for such valves. The invention makes use of a novel nesting of the threading section whereby a conventional female thread is replaced by a nested male thread surrounded by the translation section. The translation section (44), in turn, houses the indication (41) section inboard of the nested male threads thereby compacting three functions into one location. This design lends itself nicely to investment casting technology obviating conventional machine shop practices. The invention also combines by use of a long plug stem pin (56), the plug connection and L slot (58) functions into one location. The input function still remains separate, however, combining ultimately all functions in only three discrete locations and what appears at this time to be the ultimate compacted or nested arrangement.

Title: Plastic wood fiber foam structure and method of producing same
Inventor: RIZVI GHAUS M
IPC: B29C48/385
Filed: 2002-05-03
Abstract: A process for producing plastic/wood fiber composite foamed structures includes the steps of pre-drying wood fiber filler; mixing it with plastic to form a mixture; feeding the mixture into an extruder; introducing and mixing a blowing agent;  subject the mixture to high shear forces and extruding the mixture to produce a plastic/wood fiber composite foamed structure. The filler has a degradation temperature and an active volatization temperature. During the pre-drying step the temperature is maintained below the degradation temperature. During the mixing step the mixing temperature is maintained below the active volatilizing temperature. During the introducing and mixing step a blowing agent is introduced into the plastic/wood fiber mixture and is mixed therewith to produce a plastic/wood fiber/gas mixture.  During the subjecting step the plastic/wood fiber/gas mixture is subjected to high shear forces in the presence of high pressures and the temperature is maintained below an active volatilizing temperature.

Patent CA-2401977-A1 (CA)
Inventor: BABIN FRANCOIS
IPC: G01J1/02
Filed: 2001-03-02
Abstract: A photodetector device comprising a photosensitive detector (12; 22) and one  or more interfaces (20', 20", 28, 98) between dissimilar media is configured  so that a light beam (LB) for detection will pass through the interface(s) along a beam axis that is not normal to the interface(s). The deviation .theta. from the normal will be such that polarization dependent transmissio n introduced at the interface(s) will compensate for inherent polarization dependencz of the detector (12; 96). The deviation may be achieved by inclining the interface(s) relative to a predetermined direction along which  the light beam will be incident. Where the photosensitive detector is in a housing (84) with a window (20) through which the light beam enters the housing, the housing can be tilted. In such a case, there are three interfaces, one (28; 98) at the surface of the detector (12; 96), and one at  each surface (20', 20") of the window (20). Alternatively, the detector surface and/or the window could be tilted. Where a pigtail fiber (116) is permanently attached to the photodetector device to input the light beam through an interposed lens (106), the end of the pigtail fiber may be offset  laterally from the lens optical axis (LOA) so that the beam axis deviates fr om the normal by such an angle that the resulting polarization dependent transmission (PDT) substantially corrects for polarization dependent respons e (PDR) of the photosensitive detector. An end facet of the pigtail fiber, the  lens, and/or the window may be inclined so that they are not perpendicular t o the propagation direction of the light beam so as to reduce interference and  backreflection effects.

Inventor: MCGARIAN BRUCE
IPC: E21B47/09
Filed: 2001-04-24
Abstract: The present invention relates to a downhole method and apparatus for locating a window in a wellbore casing and determining the depth and orientation of said window. Apparatus of the present invention comprises a body (4) and a window engaging member (6) mounted on said body (4) so as to be movable between a retracted position and an extended position. The engaging member (6) is adapted to project into a wellbore window when in the extended position during use and is further adapted to engage with a first position of said window in such a way that, when pressed against said window portion, the engaging member (6) tends to slide along a wellbore edge defining said window portion so as to locate the engaging member (6) centrally in said window portion before preventing movement of the apparatus in the direction of pressing. The invention thereby allows the depth and orientation of a window in a wellbore to be determined.

Title: Pressure sensitive sensor and method of treating terminal of pressure sensitive sensor
Inventor: ISHIHARA HIDENORI
IPC: G01L1/20
Filed: 2002-12-11
Abstract: According to a pressure sensitive sensor and a method of treating a terminal of a pressure sensitive sensor of the invention, a covering portion is formed by a thermoplastic resin material for hot melt molding or a photo-curing resin material cured by absorbing light energy. That is, molding pressure in molding is lower than molding pressure in molding by a general injection molding method. Therefore, a possibility of effecting adverse influence on respective connecting portions of an electrode line, a resistor, a conductive piece and a lead wire by the molding pressure is extremely low and disconnection caused by operating the molding pressure on the connecting portions can reliably be prevented.
