With a total of 2 patents to his name, Lewis continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is the "Pulse Width Modulated Solenoid." This invention describes a solenoid system characterized by low noise levels. The noise reduction is primarily achieved by separating the solenoid device from the insulator and manifold housing using rubber isolators and multiple sets of o-rings. This design prevents metal-to-metal contact, which is a common source of noise. Additional noise reduction is accomplished by encapsulating all solenoids with the insulator, cover plate, housing, and screen carrier. Furthermore, the impact force of the armature against the sleeve is minimized by allowing fluid to vent into the upper area of the sleeve, creating a dampening effect.

Another significant patent by Lewis is the "Method of Overmolding Circuit." This method involves the punching of a bridge break and sealing it during the injection molding process of the lead frame. The bridge breaking tool is positioned over the bridge to be broken, with a collar pressing down on the circuit while a punch applies sufficient force to form the bridge break. After the bridge break is created, the punch is retracted, and molten polymer is injected to flow around the ends of the bridge break. The tool's hold-down collars and retracted punch create a molding area for the polymer, which encases the bridge break and exposed circuit area, ultimately forming a lead frame structure.
