  • Patent number: 7230879
    Abstract: The present invention provides a method and apparatus for arriving at true relative amplitude destretched seismic traces from stretched seismic traces. The method compensates for offset varying reflection interference effects due to normal moveout. Stretch factors ? and also input spectra are determined for NMOR stretched seismic traces. Estimates are then made of stretched wavelet spectra from the input spectra. A destretched wavelet spectra is then obtained. Shaping correction factors are determined by taking the ratio of the destretched wavelet spectra to the stretched wavelet spectra and are applied to the input spectra of the stretched traces to arrive at a destretched trace spectra. True relative amplitude scaling factors are computed by taking the ratio of a true relative amplitude property of the destretched wavelet spectra to a corresponding true relative amplitude property of the stretched wavelet spectra.

  • Publication number: 20040128074
    Abstract: A method for processing seismic traces to provide enhanced signal-to-noise ratio in seismic data is provided. A seismic survey of traces is obtained which has been collected over an areal region containing a grid of nodes. Each node is ideally representative of a reflection point from which multiple traces have been collected in the seismic survey. A rolling supergather aperture is used to select a subregion containing a working subset of traces. A model subset of traces is selected from proximate the center of the working subregion. Most preferably, the traces from only the center most portion of the rolling supergather aperture are selected for inclusion in the model subset of traces. The model subset of traces are composited to form a model trace. A modified subset of traces is created by comparing the individual traces with the model trace using an alignment technique, which is preferably a time varying trim statics technique.

A modified subset of traces is created by comparing the individual traces with the model trace using an alignment technique, which is preferably a time varying trim statics technique. These modified subsets of traces may then be composited into a reduced set of enhanced seismic traces having enhanced signal-to-noise ratio relative to the original seismic traces.

  • Patent number: 4390841
    Abstract: A monitoring apparatus and method are disclosed for monitoring and/or indicating energy that a battery power source has then remaining and/or can deliver for utilization purposes as, for example, to an electric vehicle. A battery mathematical model forms the basis for monitoring with a capacity prediction determined from measurement of the discharge current rate and stored battery parameters. The predicted capacity is used to provide a state-of-charge indication. Self-calibration over the life of the battery power supply is enacted through use of a feedback voltage based upon the difference between predicted and measured voltages to correct the battery mathematical model. Through use of a microprocessor with central information storage of temperature, current and voltage, system behavior is monitored, and system flexibility is enhanced.

  • Patent number: 4376536
    Abstract: A conical golf club grip for golf clubs with conventional shaft and head designs, the grip having a configuration designed to properly orient the upper hand of the user with respect to the club head and maintain the fingers firmly against the club grip throughout the backswing and follow-through, the grip having a button-hook style boss at the cap end of the grip with a downwardly directed end projection, such that there is formed a curved crotch against which the small finger of the upper hand is seated, wherein the crotch is defined in part by a straight slanted cut in the surface of the conical club grip opposite the end projection and directed toward the crotch forming a flat surface against which the end of the user's fingers can comfortably seat and automatically define a proper orientation of the club and club head with respect to the user's hands preparatory to swinging the club.
