Abstract: A device for mitigating shock loads utilizes load-fitted and form-fitted fluid capsules. Each capsule includes a pair of substantially flat end caps. Further, the end caps are parallel and are centered on a common axis. In each fluid capsule, high-tension members interconnect the two end caps to limit the axial distance between the end caps to less than a predetermined value. For each capsule, a membrane interconnects the peripheries of the end caps to enclose the fluid capsule between the end caps. Also, each fluid capsule includes a valve through the membrane to allow fluid flow between fluid capsules when a pressure on the valve exceeds a predetermined level. When a force is applied against a fluid capsule, the membrane deforms before fluid flows from the capsule to mitigate shock loading.

Abstract: A cushion for use in a helmet or body armor to mitigate shock loads (i.e. blasts or blunt impact) against the human body includes a matrix having a plurality of fluid pockets. The fluid pockets themselves are either deformable, or they can be reconfigured (e.g. emptied) and are, therefore, connected in fluid communication with an empty receiver pocket. In the latter case, a vent connects each fluid pocket to at least one receiver pocket, and a valve is imbedded into the vent to control fluid flow through the vent. In either case, when the cushion receives a shock load, fluid in the cushion is transferred to reconfigure the cushion for mitigation of the resultant forces.
