Latest Patents

Eynon’s patent, “Hands-free cabin purification system for a vehicle,” describes a system designed to purify air inside a vehicle cabin. A fan moves air past a UVC light source and a photocatalytic oxidizer element coated with anatase and rutile forms of titanium dioxide. The illuminated coating helps convert compounds in the airflow into hydrogen peroxide, which is distributed into the cabin.

His patent, “Vehicle door handle apparatus and two-shot injection molding process for producing components with a metallic surface finish,” describes a handle with a reinforced structural core and a molded outer layer. The core uses an engineering thermoplastic reinforced with glass fibers, while the outer layer combines an engineering thermoplastic with milled material to create a metallic appearance. The patent also describes a two-shot injection molding process for producing components with this finish.
