20100226203 | SYSTEM AND METHOD FOR UNDERWATER SEISMIC DATA ACQUISITION - A seismic source is provided that uses suitable low frequency acoustic transducers enabling a complex chirp to be used while increasing the effective power level and keeping the peak power down to a fraction of this effective power. The transducers can be driven using a pseudo-random coding of chirps that change frequency in each contiguous burst within the chirp and the interval between chirps varied to provide a pseudo-random duty cycle allowing multiple signals to be present in the water at the same time with a wider spectral coverage. By changing the timing of the drive signal for specific transducers, the direction of the source beam can be altered to steer the beam towards or away from certain objects or areas. | 09-09-2010 |

20110239327 | Nematicidal Effects of Cysteine Proteinases and Methods of Use Thereof to Treat Nematode Infestation - This invention provides methods and compositions for control of nematicidal damage to economically important plants by contacting the nematodes with cysteine proteinases. The cysteine proteinases may be provided as crude plant extracts or as refined enzyme extracts. In addition, the cysteine proteinases may be provided by the plants expressing these enzymes. Furthermore, the cysteine proteinase treatment according to this invention may be utilized to potentiate the anti-nematode effects of a non-enzymatic nematicide. | 09-29-2011 |

20140116715 | SYSTEM AND METHOD FOR MONITORING A SUBSEA WELL - A system for monitoring a subsea well is presented. The system includes the subsea well, where the subsea well includes a production tube, an annulus A co-axial to the production tube and positioned exterior to the production tube, an annulus B co-axial to the annulus A and positioned exterior to the annulus A, and a casing wall disposed between the annulus A and annulus B. Furthermore, the system includes a first sensor disposed on or about the production tube, the annulus A, the casing wall, or combinations thereof and configured to measure a first parameter. The system also includes a controller coupled to the subsea well and configured to analyze the first parameter measured by the first sensor and detect an anomaly in one or more components of the subsea well. Methods and non-transitory computer readable medium configured to perform the method for monitoring a subsea well are also presented. | 05-01-2014 |
