Title: Innovations by David P Paul
Introduction
David P Paul is an accomplished inventor based in Essex Junction, Vermont. He has made significant contributions to the field of measurement technology, holding two patents that showcase his innovative approach to solving complex problems.
Latest Patents
One of his latest patents is titled "Method for measurement of full-two dimensional submicron shapes." This invention involves a method and apparatus for extracting two-dimensional image shapes from image data on a pixel array. The process includes selecting intensity versus pixel information in multiple directions near the edge of the image shape and recognizing scans with sufficient contrast as containing edge information. Acceptable scans undergo an edge detection algorithm to detect edge locations and generate a locus of points that define the two-dimensional shape of the image. The algorithm can be user-defined and tailored to specific applications.
Another notable patent is the "Method and apparatus for measuring the profile of small repeating lines." This method allows for nondestructive determination of the line profile or topographical cross-section of repeating lines on a substrate. It includes measuring line thickness, line width, and the shape of the line edge. The substrate is illuminated with broad-band radiation, and the diffracted radiation is collected and analyzed to provide an intensity versus wavelength curve. The method utilizes Maxwell's equations to adjust the model of the line profile until the best agreement between measured and calculated intensity curves is achieved.
