摘要： In an exemplary media implementation, one or more electronically-accessible media include electronically-executable instructions that utilize an application programming interface, the application programming interface facilitating creation of callback-type dynamic function tables; each callback-type dynamic function table including a begin address, an end address, and a callback function, each callback-type dynamic function table corresponding to a code heap that stores code for multiple functions in a runtime environment; wherein interaction between the runtime environment and an operating system is precipitated upon calling the callback function to acquire exception handling and/or unwind information. In another exemplary media implementation, one or more electronically-accessible media include at least part of an operating system that is configured to request from a runtime environment exception handling and/or unwinding information for functions that are managed by the runtime environment.

摘要： A marine seismic bottom geophone anchor and coupling device comprising two rectangular fabric sections attached along their edges and along a plurality of lines between edges to form a plurality of pockets. The pockets are filled with a weighting material. Connecting means are provided so that when the combined fabric sections are wrapped around a marine seismic bottom geophone, it will be held in a generally cylindrical form to simultaneously anchor the geophones and associated cables at a desired marine bottom location, isolate the sensors from noise sources, and provide good coupling to the marine bottom for receiving desired seismic signals.

摘要： A method and system for using sonography to image the internal structure of geophysical and geologic models are disclosed. The sonography system includes a wand having a plurality of piezoelectric elements at an active surface thereof, each coupled to driver/receiver circuitry. Certain of the piezoelectric elements are selected as ultrasonic sources and receivers; the source/receiver designation may vary over time, as each of the elements may either generate or receive acoustic energy. A computer system, connected to the wand, receives signals from the receivers corresponding to reflected and refracted ultrasonic energy, and generates a zero offset trace image therefrom. In the geophysical case, the scale model is formed of materials such as plastics and rubbers having the desired properties for simulating the response of a portion or layer in the earth to ultrasonic vibrations. Sonography serves to measure the actual structure of the geophysical model, so that the effectiveness of seismic survey designs and data processing techniques may be evaluated. In the geologic case, the model is formed of clays, and a force applied thereto from one side. Sonography allows for real-time visibility into the internal structure of the model during the application of the force, so that the internal dynamics can be monitored. Dry sand geologic models can utilize sonographic inspection via a metal plate on the bottom of the model, which provides coupling of the ultrasonic energy into the dry sand bed.

摘要： A method of forming a scale model for simulation of a seismic survey is disclosed. The model includes layers which are formed by way of stereolithography or similar methods, from a CAD data base; the precision of the formation of the layers allows for construction of the model without adhesives between all layers for structural integrity of the model, although adhesive or a wetting agent may be used, depending upon the desired simulation experiment. The model also includes molded layers which are poured, injected, or otherwise introduced in liquid form. The liquid may then be solidified, or may remain in liquid form, depending upon the survey. These molded layers may be made into the prefabricated layers where appropriate, or during the process of constructing the model. Simulation of the survey may be made by imparting acoustic energy thereinto and detecting the same. The disclosed method allows for iteration of the simulation in an efficient manner, as certain of the layers may be removed and replaced with others, due to the precision of the prefabrication process. Further iteration may efficiently be made by reconstruction of the entire model, due to the efficiency of the formation of the various layers.

摘要： A marine seismic surveying system and method are disclosed. A plurality of receiver arrays, each arranged as groups of receivers (hydrophones or geophones) mounted along a cable, extend from a central location thereamong, and are connected to a platform near the central location. Systems with single and multiple platforms and their associated arrays are disclosed. The arrays each extend from the central location in different directions, preferably in a symmetrical fashion, and have their terminal ends fixed in position by way of an anchor or dynamic positioning means. Position and depth indicating instruments are also preferably mounted in each array, and at other locations in the area so that the receivers may be accurately located. The survey is accomplished by a seismic source traveling along a path which intersects the lines defined by one or more of the seismic arrays at an angle, for example a 45.degree. angle for perpendicularly deployed arrays. As a result, seismic data is acquired which is uniform in fold, and which has distributed offset distances and azimuths for each bin, so that full 3-D surveys and VSP can be readily performed with high accuracy and efficiency.

摘要： A seismic cable assembly having an acoustically transparent tubular enclosure has at least one hydrophone electrically connected and positioned within the cable assembly enclosure. The hydrophone is made up of a pair of formed, electrically conductive plates that fit against an insulating seal which also forms a fluid seal, providing a sealed chamber defined by the inside surfaces of the conductive plates. A pair of piezoelectric elements are interconnected and positioned within the sealed chamber, one element mechanically and electrically connected to the inside surface of one of the conductive plates and the other piezoelectric element mechanically and electrically connected to the inside surface of the other conductive plate. When pressure is applied to the conductive plates, they deform, causing the piezoelectric elements to flex. When the elements flex, an electrical output is presented on the conductive plates which serve as terminals. Depending upon the polarity relationship of the elements, the output is that of an acceleration-cancelling hydrophone, or that of an accelerometer.
