One apparatus comprises a source connected to a tow member; and an adjustment mechanism connected to the source and the tow member, the adjustment mechanism adapted to actively manipulate an angle of attack of the source. It... http://www.freshpatents.com/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-dt20081211ptan20080304358.php Fri, 19 Dec 2008 00:10:18 -0800 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... http://www.freshpatents.com/Processing-seismic-data-dt20081211ptan20080304359.php Fri, 19 Dec 2008 00:10:18 -0800 A method of processing seismic data including convolving at least first and second seismic data traces or respective portions of at least first and second seismic data traces to forma composite trace. The travel time of an event may then be determined in the composite trace. This provides an improved... http://www.freshpatents.com/Systems-and-methods-of-sonic-communication-dt20081211ptan20080304360.php Fri, 19 Dec 2008 00:10:18 -0800 In one embodiment the present invention includes a method of wireless communication. The method comprises receiving a sonic signal and determining a sequence of sonic tones from a received sonic signal. The receiving includes receiving the sonic signal at an electronic device using a microphone. The sonic signal includes a... http://www.freshpatents.com/Acoustic-ranging-dt20081211ptan20080304361.php Fri, 19 Dec 2008 00:10:18 -0800 Acoustic ranging may involve determining a distance between a first device and at least one other device using one or more acoustic signals. In an example embodiment, a first device emits a first acoustic signal and then receives the first acoustic signal at a first time. The first device also... http://www.freshpatents.com/Inter-diver-signaling-device-and-process-dt20081211ptan20080304362.php Fri, 19 Dec 2008 00:10:18 -0800 Taps on a beam-interrupt button of an underwater signaling transceiver are encoded as binary frequency shift-key modulated Golay codes, which are transmitted via 56-58 kHz compression waves generated by a ring-shaped electromechanical transducer. Light emitting diodes flash to signal the content of received signals and provide monitoring of the distance... http://www.freshpatents.com/Method-and-apparatus-for-positioning-a-center-of-a-seismic-source-dt20081211ptan20080304363.php Fri, 19 Dec 2008 00:10:18 -0800 The present invention provides a method and apparatus for positioning a center of a seismic source. The method includes determining a desired center-of-source of the seismic source and selecting one of a first and a second plurality of guns to form the seismic source based upon the desired center-of-source, a...
