Title: Innovations of Peter Clark Smith
Introduction
Peter Clark Smith is a notable inventor based in Half Moon Bay, California. He holds a total of nine patents, showcasing his contributions to technology and innovation. His work primarily focuses on advancements in electron gun technology and radiation protection.
Latest Patents
One of his latest patents is a multi-layer heater for an electron gun. This invention features layers of substrate material made from ceramic powder, such as aluminum nitride. The conductive traces on these layers are formed from sintered tungsten or a refractory foil. When current flows through these traces, heat is transferred to a cathode thermally coupled to the heater assembly. Another embodiment includes a thermionic emission material that allows the outer layer to emit electrons directly. Additionally, a control grid can be formed above the thermionic cathode layer, enabling the fabrication of a complete electron gun assembly as a single unit.
Another significant patent is a lightweight radiation-absorbing shield. This flexible shield consists of heavy metal particles in one layer and mid-atomic number particles in another layer, which is adjacent to the patient. This design aims to protect the wearer and others from radiation emitted from a therapeutic source within the patient's body. The multi-layer construction minimizes backscattered radiation affecting the patient's adjacent tissue.
