Title: Innovations by David Perry

Introduction

David Perry is an accomplished inventor based in the Village of Lakewood, IL (US). He holds 2 patents that showcase his expertise in developing innovative solutions for circuit protection.

Latest Patents

One of his latest patents is titled "Voltage variable material for direct application and devices employing same." This invention provides overvoltage circuit protection by introducing a voltage variable material (VVM) that includes an insulative binder. The binder is designed to adhere intrinsically to both conductive and nonconductive surfaces. It is self-curable and can be applied in the form of an ink, which dries to a final form suitable for use. This innovation eliminates the need for separate devices or printed circuit board pads for electrical connections. The VVM can be directly applied to various substrates, including rigid laminates and polymers.

Another significant patent is "Connectors having circuit protection." This invention offers a device that works with existing or new connectors to provide overvoltage protection. It features a strip of conductive material with VVM applied along its length. The design includes an exposed portion without VVM deposition, allowing the VVM to contact multiple signal conductors while the exposed portion connects to at least one ground conductor. In the event of an overvoltage condition, the VVM transitions from a high impedance to a low impedance state, enabling the transient threat to dissipate to the ground conductor.
