With a total of 4 patents to his name, Edmonson has made significant advancements in the technology of transparent materials and data storage systems.
Latest Patents
One of Edmonson's latest patents is a method of improving the color of transparent materials. This invention involves a faceted gemstone that has at least one thin layer of material coated on the pavilion of a transparent substrate. This innovative design allows the body of the gemstone to appear to have a different color, as the color of reflected light changes hues when viewed through the face of the gemstone at different angles. This unique feature causes the gemstone to appear to change color when tilted. The thin film is coated using low-temperature techniques such as sputtering.
Another significant patent by Edmonson is for a method and apparatus for coating thin film data storage disks. This invention presents a vacuum deposition system in the form of a sputtering system for rigid disk substrates. It utilizes a single vacuum envelope and a single transport to avoid multiple pump downs or valved isolation structures during the multiple coating processes. The design enhances system throughput by partitioning the longest duration process steps to be performed at multiple successive work stations.
