  • Patent number: 7421348
    Abstract: A method for predicting emissions from an emissions source. Test values of process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated test values of the emissions variable to be predicted. Using the test values of the process variables, test values of a plurality of first coefficients are calculated for each process variable and associated with the process variable, and test values of a plurality of second coefficients are calculated for each value of each process variable and associated with the value of the process variable. Comparison values of the process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated comparison values of the emissions variable to be predicted.

  • Patent number: 7415356
    Abstract: A facility for producing a composite aerial image is described. The facility receives information specifying a geographic area. The facility obtains an aerial image showing the specified geographic area that was prepared using one or more aerial image sections. Each aerial image section covers a geographic area defined in terms of spherical coordinates, and was constructed by copying a portion of a master aerial image that was selected using rectangular coordinates into the master image that were determined by directly transforming the spherical coordinates defining the covered geographic area. The facility obtains information indexed to one or more distinguished geographic locations within the specified geographic area and, for each distinguished geographic location, composites into the obtained aerial image a visual indication of the information that is indexed to the distinguished geographic location.

  • Patent number: 7398158
    Abstract: A unique method has been developed which can show the presence of fractures in an Earth formation as a mappable attribute. This method uses the frequency spectra derived from P-wave seismic data over a pair of specific time windows above and below a seismic horizon or reflector of interest to infer the presence or absence of these geologic fractures based on an attenuation of high frequencies. The method produces a parameter value (t*) which is proportional to the shift in frequency spectra amplitudes (i.e., energy) from higher frequencies to lower frequencies, that is, from a time-window above a horizon or reflector of interest to a time-window below the horizon or reflector of interest.

  • Patent number: 7383132
    Abstract: Method for enhancing resistive anomalies in electromagnetic geophysical survey data. Scaled values of a measured electromagnetic field parameter are plotted on a depth section at locations related to corresponding source/receiver locations. Scaling is performed relative to a reference signal selected to represent a baseline free of unknown resistive bodies. Scaled values are represented by a color scale in the display, and the color scale may be adjusted to enhance perceived anomalies. The method may be employed in either the frequency domain or the time domain.

  • Patent number: 7383128
    Abstract: Representations of data inversions are generated by alternate forms of maximum likelihood estimating and associated least-squares and regression analysis which are rendered in correspondence with either single component residual deviations or projections between data samples and inversion-conforming data sets. Deficiencies in representing likelihood as related to errors-in-variables data and heterogeneous precision are compensated by composite weighting of likelihood elements. Composite weight factors employ both normalization to establish non-skewed homogeneous likelihood elements and fundamental weighting to compensate for associated non-linearly and establish common units for combining orthogonal coordinate-oriented data-point projections. Respective weight factors are related to alternately considered fundamental variables.

  • Patent number: 7366619
    Abstract: A signal processing unit includes an integrating unit. The integrating unit is composed of a plurality of digital elements and is operative to integrate a detection signal over every quarter of one cycle of the detection signal to generate an integration value. The integration values to be generated are represented as S1, S2, S3, and S4. A calculating unit includes a plurality of digital elements and performs addition and subtraction on the generated integration values in accordance with the following equations used to calculate an in-phase component and a quadrature-phase component of (Ip=S4p?3+S4p?2?S4p?1?S4p) and (Qp=S4.4?S4p??S4p?1+S4p). Where Ip represents the in-phase component and Qp represents the quadrature-phase component. An amplitude obtaining unit obtains an amplitude of the detection signal based on the in-phase component and the quadrature-phase component.

  • Patent number: 7356439
    Abstract: An image motion detection apparatus and method detecting a motion in a moving image by sequentially being input with a plurality of fields that are temporally successive and detecting motion information values representing presence and absence of motion for each pixel/block of an input nth field. A motion calculation buffer stores the motion information values for each pixel/block; and a motion calculation unit corrects the motion information values of the input nth field stored in the motion calculation buffer unit, based on the motion information values of the n+1th field. Thus, it is possible to quickly and correctly detect motion regions and still regions in a moving image by a relatively simple method of correcting the motion information values while suppressing a spurious still region occurrence in a currently interpolated field.

  • Patent number: 7328106
    Abstract: A gas detection method includes carrying out respective neutron and density logs, using neutron and density detectors, along a length of well. The density log is corrected for the dimensions and properties of the well casing. The corrected density log is then combined with the neutron log to compensate for regions of artificially high density outside the casing. The compensated density log is continuously calibrated against the neutron log. The dynamically calibrated density and neutron logs are inspected for crossovers that signify the presence of gas in a formation.
