Patents by Inventor Sajad Jazayeri

Sajad Jazayeri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11169256
    Abstract: A new system and method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried objects. The method is useful in situations where clear isolated diffraction hyperbolas indicate the presence of an underground object, but the object's dimensions and filling may be unknown. The present invention acquires GPR data and applies advanced numerical methods to get the depth and size of the underground object in a very accurate manner. An embodiment of the invention includes five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.
    Type: Grant

  • Patent number: 10677914
    Abstract: In one embodiment, a method for detecting buried objects includes receiving ground penetrating radar (GPR) signals captured at discrete locations along a surface of a medium in which an object may be buried, computing parameters based on the received GPR signals that are indicative of the proximity of a buried object, plotting the computed parameters as a function of location, determining an apex of a hyperbola that results from the plotting of the computed parameters, and designating a location at which the apex occurs as an estimated location of the buried object.

  • Patent number: 10234552
    Abstract: A new method for FWI of common-offset GPR data, particularly targeting the dimensions and infilling material of buried pipes. The method is useful in situation where clear isolated diffraction hyperbolas indicate the presence of a pipe, but pipe dimensions and filling may be unknown. The invention is a method of taking GPR data and applying advanced numerical methods to get the depth and size of an underground pipe in a very accurate manner. An embodiment of the method consists of five main steps: GPR data processing, ray-based analysis to set a good initial model, 3D to 2D transformation of data, effective SW estimation, and FWI.
