Novel, Multi-Impact, Energy Diverting, Energy Absorbing, Repairable Helmets

Executive SummaryThis technology addresses brain injuries while wearing a helmet. A novel technique adds an outer layer to helmet shells to absorb multiple impacts and divert energy away for the skull to reduce concussions. The innovation can also reduce projectile penetration in a way that is repairable and re-healable for low or multiple low-velocity...

Scanning interferometry technique for through-thickness defect/damage evaluation in multi-layered transparent structures

IntroductionHigh-strength, impact-resistant windshields, security components, and other multi-layered transparent composites (TC) are often constructed with glass and polymer laminates. Precise measurement of flaws in these structures, in all three dimensions, has not been possible. As a result, manufacturing costs include unnecessary scrap, and components...
