Title: The Innovative Contributions of Donald F. Shepard
Introduction
Donald F. Shepard is a notable inventor based in Evergreen, Colorado, with a remarkable portfolio of ten patents. His work primarily focuses on advancements in geolocation systems and materials science, showcasing his commitment to innovation and technology.
Latest Patents
One of Shepard's latest patents is a Physical Geolocation System. This real-time system determines the geographic movements of individuals or objects by sampling particulates contained thereon. The system includes particle collection, sample preparations, and sample analysis using three primary modes of detecting certain particulates. The first mode involves imaging pollen, spores, or other biological materials visible through a light microscope when properly stained or prepared. The second mode utilizes real-time polymerase chain reaction to amplify and detect target nucleic acid sequences. The third mode employs X-ray diffraction to identify mineral particles. The results from any mode, or any combination of modes, are analyzed by comparison to a reference database containing geographic information, and the results are compiled by a controller for visual display.
Another significant patent is for a High-Temperature, High-Emissivity, Optically Black Boron Surface. This article of manufacture comprises a substrate and an optically black surface on the substrate, having an absorptivity of more than about 0.89 and an emissivity of more than about 0.86. The surface consists of boron particles plasma spray applied to the substrate using a powder selected from the group consisting of crystalline boron with a particle size finer than about 200 mesh and amorphous boron.
