20080304358 | Method of Assisting The Deployment/Retrieval of Linear Acoustic Antennas Towed By A Vessel, During The Course of Which Distance-Measuring Means Carried By The Antennas Communicate with One Another - A method of assisting the deployment/retrieval of linear acoustic antennas towed by a vessel, said linear antennas each having geophysical data sensors, means for measuring the distance of at least one adjacent linear antenna, during the course of which at least one of said linear acoustic antennas has at least longitudinal mobility in relation to said vessel, including: at least one phase for configuring cells (Cn) each defined by a central position corresponding to a distance-measuring means (T), and by at least one peripheral position corresponding to another distance-measuring means (T) in proximity to said distance-measuring means (T) for said central position, reference distances between said central positions and said peripheral positions being predetermined; and at least one phase for controlling said central and peripheral positions with respect to said reference distances, by establishing communication between at least some of said distance-measuring means (T). | 12-11-2008 |
20090003135 | System for Localizing and Positioning Towed Acoustic Linear Antennas - A system for localizing and positioning towed acoustic linear antennas. In one aspect, a system for localizing and positioning towed acoustic linear antennas includes two or more linear antennas, where each linear antenna has at least one distance measurement device configured to measure the distance to at least one adjacent linear antenna and to transmit signals corresponding to distance measurements. The system further includes one or more navigational control devices along each linear antenna that are configured to control at least the lateral position of each linear antenna. The system also includes one or more controllers distributed over the length of each linear antenna, where each controller is configured to receive distance measurement signals from at least one distance measurement device, process the distance measurement signals, and to control at least one navigational control device according to the processed distance measurement signals. Other aspects are disclosed. | 01-01-2009 |
20100329075 | METHOD FOR ASSISTANCE IN THE LOCALIZATION OF TOWED STREAMERS COMPRISING A STEP FOR DEFINING AND A STEP FOR GENERATING DISTINCT ACOUSTIC CYCLES - A method for assistance in the localization of streamers towed by a vessel including at least one onboard acoustic controller, each streamer having: geophysical data sensors; acoustic means for measuring distance from at least one adjacent linear antenna; and means for the absolute localization of said antennas. The method includes at least one phase for the generating an acoustic cycle determining sequences and at least one phase for defining at least two distinct acoustic cycles representing a theoretical geometry capable of representing the shape of said streamers; at least one step for determining the real geometry of said streamers; at least one step for detecting a change in real geometry followed by a step for generating a new acoustic cycle, selected from among those defined during said phase for defining and adapted to said change in real geometry. | 12-30-2010 |

20140029379 | METHOD FOR STEERING A TOWED ACOUSTIC LINEAR ANTENNA - A method and apparatus are provided for steering a first acoustic linear antenna belonging to a plurality of acoustic linear antennas towed by a vessel. A plurality of navigation control devices are arranged along the plurality of linear antennas in order to act at least laterally on the position of the linear antennas. At least one of the navigation control devices arranged along the first acoustic linear antenna performs steps of: obtaining a local measurement of a feather angle or of a parameter linked to the feather angle, the local measurement being associated with the at least one of the navigation control devices arranged along the first acoustic linear antenna; computing a lateral force, as a function of the obtained local measurement; and applying the computed lateral force. | 01-30-2014 |
20140104981 | SEISMIC CABLE FOR SEISMIC PROSPECTION TOLERANT TO FAILURE ON POWER SUPPLYING AND/OR DATA TRANSMISSION LINES - A seismic cable including sensors, data transmission lines extending the length of the seismic cable for conveying data signals issued from the sensors. Controllers distributed along the seismic cable operate as an interface between the sensors and the data transmission lines. Power supplying lines supply power to the controllers and the sensors. X power supplying lines are alternately connected to one out of X successive controllers. Each controller is adapted for applying on a power supplying line detected as defective the electrical tension provided by another power supplying line. Y data transmission lines are alternately connected to one out of Y successive controllers. Each controller is adapted to redirect towards at least one adjacent controller the data associated with a data transmission line which is determined to be defective. | 04-17-2014 |

20110282133 | TRANSOBTURATOR SURGICAL ARTICLES AND METHODS - A surgical instrument for treating incontinence includes a handle portion elongate along a handle axis and a needle portion connected to the handle portion. The needle portion has a spacer portion along the handle axis, and has a distal end. The needle portion includes a substantially helical portion that is a variable spiral portion, extending from the straight spacer portion. The variable spiral portion is sized and shaped to extend from an incision substantially adjacent the patient's obturator foramen through the obturator foramen along a path in a region between the superior pubic ramus and the inferior pubic ramus. The needle portion has a structure near the distal end that associates the instrument with an implantable material configured to treat incontinence. | 11-17-2011 |
