Darryl Nowak of New Jersey has been a marine construction consultant for over 33 years.
On Tuesday, Nowak licensed from the U.S. Navy a new tool for measuring the fatigue of metal structures.
Invented by the Naval Air Warfare Center's Aircraft Division (NAWCAD) at Patuxent River, Maryland, the patented technology will allow his customers to gauge the growth of invisible micro-cracks, which slowly grow to cripple metal structures.
