Shock Mitigation Utilizing Quiescent Cavitation

Abstract

The present invention is directed to a device for mitigating physical shocks that utilizes quiescent cavitation to temporarily store impact energy and is further directed to a concussion mitigation helmet employing this device. A primary use of helmets is to shield the head from injuries caused by impact or sudden accelerations. It is well-known in the art of helmet design to provide various types of impact absorbing material between an outer surface of a helmet and a wearers head. When the helmet is subjected to an impact this material collapses to absorb energy from the impact and to distribute the energy over a wider surface area for a longer period of time.
