Patent CA-2160968-C (CA)
Inventor: MEYER HAROLD WALLACE JR
IPC: G01V3/38
Filed: 1995-10-19
Granted: 2006-05-23
Abstract: The current invention is directed toward the use of a downhole computer and downhole storage within a measurement-while-drilling (MWD) downhole subassembly to process data from the response of a plurality of sensors of different classes or one or more sensors of the same class which exhibit different measure points and vertical resolutions. Classes or types of sensors applicable to the invention include, but are not limited to, electromagnetic, acoustic, and nuclear. Sensor measurements are made essentially simultaneously. In combining downhole responses from one or more sensors to obtain parameters of interest, a critical prerequisite is downhole depth correlation and vertical resolution matching of all sensor responses prior to combination. Methods and apparatus are disclosed for performing these critical functions within the limits of telemetry and downhole storage capacities of current MWD systems, Alternate embodiments of the invention include wireline operations in which telemetry band width is limited by components such as single conductor logging cables employed in logging wells under high pressure.

Abstract: A speech-recognition system for recognizing isolated words includes pre-processing circuitry (3) for performing analog-to-digital conversion and cepstral analysis, and a plurality of neural networks (12-14) which compute discriminant functions based on polynomial expansions. The system may be implemented using either hardware or software or a combination thereof. The speech waveform of a spoken word is analyzed and converted into a sequence of data frames. The sequence of frames is partitioned into data blocks, and the data blocks are then broadcast to a plurality of neural networks. Using the data blocks, the neural networks compute polynomial expansions. The output of the neural networks is used to determine the identity of the spoken word. The neural networks utilize a training algorithm which does not require repetitive training and which yields a global minimum to each given set of training examples.

Title: Method of assembling log walls for log house and clamping bolt to couple the wall
Inventor: FUTAGI KOHZOH
IPC: E04B2/70
Filed: 1996-11-19
Granted: 2004-06-22
Abstract: A first story log house material is adhered to a base with a coach bolt and succeeding log materials after a second story are piled up in turn with clamping bolts.   A coach bolt or a clamping bolt has a height corresponding with one long thickness and is equipped with a nut portion and a wahser. This method of assembling log walls for the log house eliminates the accumulated shrinkage for the log wall during the drying period.

The barrier arm is positioned within the groove of the guide element and the needle cannula is positioned at least partially within the burner element. The barrier arm is movable from at least a first retracted position wherein the distal end of the cannula passes through the burner element so that the distal end of the needle cannula is exposed, to a second extended position wherein the barrier element surrounds the distal end of the needle cannula to help prevent accidental contact with the distal end of the needle cannula. Locking structure to prevent movement of the barrier arm from the second extended position is activated by movement of the barrier arm into the second extended position.

Title: Expandable stent and method for delivery of same
Inventor: PENN IAN M
IPC: A61F2/915
Filed: 1997-03-05
Granted: 2007-10-23
Abstract: An expandable stent comprising a proximal end and a distal end in communication with one another and a tubular wall disposed between the proximal end and the distal end. The tubular wall has a longitudinal axis and a porous surface defined by a plurality of intersecting members comprising a series of longitudinal struts disposed substantially parallel to the longitudinal axis of the stent. Each longitudinal strut in the series comprises flexure means for substantially complementary extension and compression of a diametrically opposed pair of the longitudinal struts upon flexure of the stent. The stent is expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force on the stent. The provision of such flexure means in the series of longitudinal struts leads to a very desirable balance of lateral flexibility of the unexpanded stent and radial rigidity of the expanded stent.
