  • Patent number: 9811614
    Abstract: System and method for correcting the vertical structure of the ocean temperature and salinity based on velocity observations. Three relations that can be precomputed are exploited: (1) the relation between temperature and salinity throughout a water column, (2) the relation between temperature/salinity and geopotential, and (3) the relation between geopotential and velocity. The relations are stored in a form that allows efficient application through a cross-correlation matrix.

  • Patent number: 9594178
    Abstract: The technologies described herein include systems and methods for performing a first seismic survey and performing a second seismic survey after a predetermined amount of time has lapsed between the first seismic survey and the second seismic survey. The shot times and the shot positions of the second seismic survey may be substantially the same as the shot times and the shot positions of the first seismic survey. After performing the seismic surveys, seismic data generated by the first seismic survey may be processed to generate a first image, and seismic data generated by the second seismic survey may be processed to generate a second image. After generating the first and second images, a difference between the first image and the second image may be computed to generate a time lapse difference image.

  • Patent number: 9495778
    Abstract: According to one embodiment, an information presenting apparatus receives each observed value from sensors, and maintains a track of each target by updating the track based on an observed value having a correlation with the track. A likelihood ratio for a tentative track, which has not yet been determined to be a track of a target, is computed and compared with an upper limit threshold. When the likelihood ratio is greater than or equal to the upper limit threshold, the tentative track is determined to be a track of a target. When the likelihood ratio is greater than or equal to a monitor threshold which is lower than the upper limit threshold, the tentative track is determined to be a monitor track. The information of the track and the monitor track are presented.

  • Patent number: 9423490
    Abstract: A noise source localization process that uses as few as four microphones in an antenna array. The process combines different averaging to the information from the various signals with non-linear (wavelet-based) filtering, cross-correlation and triangulation to more particularly locate a noise source relative to a target point. The process calculates a propagation time based on the distance from a target to each microphones, delays each of the signals according to the propagation time from the target, calculates a continuous wavelet transform for each of the signals to band-pass filter each of the signals according to a predetermined frequency of interest, determines the product of each pair of signals to produce correlation fringes, and locates the noise source based on the product of the pairs of signals.
