| 20100142326 | Method For Identifying Gas Leaks Using A Stationary Seabed Placed Steered Beamformed Acoustic Antenna With Active Narrow Beam Transmitter Interrogation Capability - A method for identifying position of acoustic source proximate sediments below the bottom of a body of water includes deploying a plurality of arrays of acoustic sensors on the bottom of the body of water. Each array includes a plurality of lines of acoustic sensors disposed in a substantially radial pattern. The arrays have a center to center distance therebetween of about twice a diameter of each of the arrays. Signals are detected from each of the sensors for a selected time period. A direction of the acoustic source with respect to each of the arrays is determined by steering a response of the sensors in each array. A range of the acoustic source is determined using the determined directions. | 06-10-2010 |
| 20100328138 | SHORT BASELINE HELICOPTER POSITIONING RADAR FOR LOW VISIBILITY - A method for determining position and orientation of a rotating wing aircraft (e.g. helicopter) with respect to a ground station includes transmitting an electromagnetic signal from the aircraft. The signal includes a plurality of electromagnetic signals, each signal having a different selected frequency. The signal is detected at an array of sensors disposed on the ground surface in a selected pattern. The array includes at least one reference sensor and at least three spaced apart time difference determination sensors. A difference in arrival time of the signals between the reference sensor and each of the time difference determination sensors is determined and a spatial position of the aircraft is determined from the time differences. | 12-30-2010 |
| 20110158048 | SPIRAL SENSOR CONFIGURATION FOR SEISMIC BEAMFORMING AND FOCUSING - A seismic sensor array includes a plurality of seismic sensors disposed on a line. The line is arranged in a spiral. The seismic sensors are disposed at at least one of equal angular spacing between adjacent sensors and equal linear spacing between adjacent sensors. A recording system is in signal communication with each of the seismic sensors. The recording system includes means for beam steering a response of the sensors. | 06-30-2011 |

| 20110075520 | SEISMIC SOURCE WHICH INCORPORATES EARTH COUPLING AS PART OF THE TRANSMITTER RESONANCE - An acoustic energy source for imparting acoustic energy into the Earth's subsurface includes an electrically driven transducer coupled to a source of swept frequency alternating current. A tunable Helmholtz resonator is disposed proximate the transducer. In one example, the resonator has a tuning device configured to maintain a resonant frequency substantially equal to an instantaneous frequency of the alternating current. The tuning device includes an actuator coupled to a sleeve, wherein the sleeve is disposed over selected numbers of openings in a wall of a tube on the resonator. The transducer and the resonator are disposed in a wellbore drilled through rock formations. The wellbore has a plurality of layers of fluid therein, each layer thereof having a different density and/or viscosity. | 03-31-2011 |
