I am an independent inventor (14 issued US Patents) and safety consultant / advisor. My patent work concerns: Safety, sensors, LEDs and light guide technologies. I am a peer reviewed globally published, peer reviewed author with SPIE (The Society for Advancing Light Based Research). I am on six ANSI Accredited U.S. Technical Advisory Groups (TAGs) for The International Organization for Standardization's: ISO/TC 58, Gas cylinders; ISO/TC 58/SC 2, Gas fittings; ISO/TC 58/SC 3, Cylinder design; ISO/TC 58/SC 4, Operational requirements for gas cylinders; ISO/TC 197, Hydrogen technologies; and ISO/TC 220, Cryogenic vessels.

The Hydrogen Technologies TAG's focus is on safety and performance for hydrogen vehicle pumps, stations, and the vehicle's receptacle. We develop and vote on the standards for all participating countries, including: China, India, Japan, Germany, Canada, France, Russia, etc.

I am an officially registered U.S. expert on four International Organization for Standardization (ISO) Working Groups (WGs) in the hydrogen technologies sector:

• ISO/TC 197/WG 5-Gaseous hydrogen land vehicle refueling connection devices.
• ISO/TC 197/WG 22-Gaseous hydrogen fueling station hoses.
• ISO/TC 197/WG 23-Gaseous hydrogen fueling station fittings.
• ISO/TC 197/WG 24-Gaseous hydrogen fueling stations – General requirements.

These WGs include hydrogen filling station components and their attachments to hydrogen powered vehicles, for all participating countries, including: China, India, Japan, Germany, Canada, France, Russia, etc.

Developed proprietary, high power, compact LED automotive lighting with RipDark Ltd., Shenzhen, China. RipDark is a cutting edge, engineer-based lighting company focused on advancing OEM, ODM and aftermarket LED automobile lighting. RipDark has filed fifty patent applications that focus on circuit performance, structure, and optical design.

I have twenty three years of safety, LED,  glass,  fiber optics and light guide technologies experience. My work concerns  illuminating surfaces and areas without bulbs, wires or wired sensors, in toxic, volatile or hostile environments. I have been on Working Groups for vented and non-vented gas equipment, and my work has many safety advances that can be applied to hydrogen technologies. In discussing safety with my TAG Chair I identified vehicle lighting improvements that could make vehicles safer. I have also developed compact premium LED daytime running lights with a global automotive lighting supplier. I hope to be on vehicle lighting TAGs administered by SAE, because that would enhance my standards work with ISO. We need to make hydrogen stations and vehicles as safe and consumer friendly as possible, as they roll out. So much is at stake.
