20120106296SEISMIC DATA ACQUISITION SYSTEM COMPRISING MODULES ASSOCIATED WITH UNITS CONNECTED TO SENSORS, THE MODULES BEING AUTONOMOUS WITH RESPECT TO POWER SUPPLY, SYNCHRONISATION AND STORAGE - A module for operation in a seismic data acquisition system is described. The seismic data acquisition system includes a cabled network with a plurality of acquisition lines having electronic units assembled in series along a telemetry cable. Each electronic unit is associated with at least one seismic sensor and processes signals transmitted by the sensor(s). The module is designed to be associated with at least one of the electronic units to provide power supply and synchronization to the electronic unit(s). The module includes: autonomous synchronization means; bidirectional and autonomous power supply means to power at least one electronic unit upstream and/or downstream from the module; and means for storing and processing the signals processed by the electronic units, the storage means being bidirectional to store the signals from at least one electronic unit upstream and/or downstream from the module.05-03-2012
20100329075METHOD 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
