Inventor: WATSON JOHN DAVID
IPC: E02D29/00
Filed: 2007-04-19
Abstract: The present invention discloses a selection process for installing underground workspace in or near a hydrocarbon deposit that is an appropriate workspace from which to drill, operate and service wells applicable to any of a number of methods of recovering hydrocarbons. The present invention includes a number of innovative methods for developing workspace for drilling from a shaft installed above, into or below a hydrocarbon deposit, particularly when the hydrocarbon reservoir is at significant formation pressure or has fluids (water oil or gases) that can enter the workspace. These methods can also be used for developing workspace for drilling from a tunnel installed above, into or below a hydrocarbon deposit. The present invention also discloses a procedure for evaluating the geology in and around the reservoir and using this information to select the most appropriate method of developing workspace for drilling from a shaft and/or tunnel.

Title: Method to control error floor in analog neural ldpc decoder
Inventor: BOIKO YURI B
IPC: H03M13/19
Filed: 2009-01-05
Abstract: Analog decoder for (16,4) Hamming code is simulated with neural design of the check nodes. Error distributions of 3D and 4D mapping for various check nodes based on multilayer perceptron architecture is obtained in simulation after supervised training of neural mappers. For random code-words performance of neural decoder is found to be suboptimal to atanh(.) based ideal decoder. Error floor is shown to be a function of the error distribution in the check nodes. Optimal distribution is achieved when error for training points and those most remote from training points are close to one another with overall precision been about twice better. Control of the error floor via optimization of the error distribution in the check node's mappers is demonstrated, improving the achieved error floor for neural analog type decoder down to BER values of about 10 -6.  Over-enhanced error distribution (with precision for intermediate points higher than that for training ones) exhibit deterioration in the performance, demonstrating error floor of about 10 -4 BER.

Title: Capacitive displacement transducer for a weak-motion inertial sensor
Inventor: ACKERLEY NICK
IPC: G01V1/18
Filed: 2009-03-06
Abstract: A capacitive displacement transducer for use in a broadband weak-motion inertial sensor having a frame, a movable inertial mass, a forcing transducer for keeping the inertial mass stationary relative to the frame during operation, and a flexure for suspending the movable mass in the frame. Two or more closely spaced, substantially parallel capacitor plates, at least one attached to the frame, and one attached to the movable inertial mass, form a capacitive displacement transducer. The capacitor plates have a plurality of apertures with dimensions and arrangement chosen to simultaneously minimize damping induced thermal noise and give a high spatial efficiency. An embodiment comprises three capacitor plates, each with the same hexagonal pattern of circular holes; the holes are aligned on all three capacitor plates. Radius and spacing of the holes are dictated by a relationship that determines the minimum damping per unit capacitively effective area for a desired spatial efficiency, gap height and capacitor plate thickness. In an embodiment the capacitor plates are made of a printed circuit board material which, through etching of the thin conductive layer, can be mounted directly to a conductive frame and conductive inertial mass without the use of non-conductive spacers.

Abstract: Apparatus for controlling the placement of seeds deposited by a seed placement device in a furrow. The apparatus comprise a guide member connected to the seed placement device adjacent an exit of the seeds from the placement device adapted to urge seeds discharged from the exit toward a sidewall of the furrow. The guide member of the present invention acts to stop seeds from bouncing off the sidewalls of the furrow and into the centre of the furrow. The guide member organizes the seeds to create one or more seed rows where the seeds are optimally positioned and prevents seeds from ending up in the middle of the furrow. If a fertilizer row is present below the seed furrow, this prevents damage to the seeds by preventing them from being too close to the fertilizer. The guide member also stops the seeds from being swept back into the central region of the furrow with the loose soil that flows back into this area after the knife implement has passed.

Filed: 2007-12-14
Abstract: The invention relates to a method of, and an apparatus for, controlling the transportation of a plurality of articles (Se-1.1, Se-1.2, etc). Each article has provided on it the specification of a destination to which the article is to be transported. Each article passes through a sorting installation (AnI-O, AnI-1, Anl-2) at least twice. During both passages through the sorting installation, a respective image of the article is generated, and this image comprises an image of the destination specification (ZP-1.1, ZP-1.2,etc.). As the article first passes through the sorting installation, the destination specification is read. This reading result is stored on an interim basis. As the article passes through the sorting installation again, an interim-storage reading result is determined. The reading results control the transportation of the articles. A check is made, according to the invention, as to whether an article has been misdirected. The method further establishes why an article was misdirected - incorrect reading result, incorrect determination of the reading result or transportation error.
