First Claim
Patent Images
1. A method of identifying a double-layer dipole from a magnetic image, comprising:
- obtaining a magnetic image of a magnetic field generated by a double-layer dipole, wherein said double-layer dipole is of undefined shape, size, depth and orientation;
submitting said magnetic image to a current dipole constructing system to determine a 3D position and momentum of an electric current in accord with the magnetic image;
assigning the 3D position of the electric current to the geometric center of a single double-layer 2D patch; and
deeming the geometric center of the single double-layer 2D patch to the position of an equivalent dipole moment of said double-layer dipole, said equivalent dipole moment being characterized by the generation of an electric field substantially similar to that produced by said double-layer dipole.

Abstract
A system identifies double-layer dipoles in a magnetic image by defining two-dimensional patches of distributed point charges that simulate the double-layer dipoles. The geometric center of a two-dimensional patch is used as the location of an equivalent dipole moment of the double-layer dipole. The momentum of the equivalent dipole moment is determined by submitting the magnetic image to a dipole construction system that identifies the location and momentum based on the submitted magnetic image.
