Patent ID: 8714071

Claim:
An overpressure wave absorbing system comprising: a protective layer; a first deflectable planar layer with a first matrix of deflectable protrusions formed therein and a second deflectable planar layer with a second matrix of deflectable protrusions formed therein wherein the first deflectable planar layer and the second deflectable planar layer each have substantially greater than fifty percent planar surface area, wherein at least one deflectable protrusion of the second matrix of deflectable protrusions is attached to an opposing deflectable protrusion of the first matrix of deflectable protrusions, and wherein one or both of the first deflectable planar layer with the first matrix of deflectable protrusions and the second deflectable planar layer with the second matrix of deflectable protrusions are configured to absorb a portion of an incoming overpressure wave and reduce a magnitude of the overpressure wave incident on the protective layer.
