Abstract: A protective helmet includes an outer shell and a controlled air dissipation (CAD) assembly installed within the outer shell. The CAD assembly includes an inner shell liner releasably mounted to the outer shell, a primary bellows unit disposed between an outer surface of the inner shell liner and the inside surface of the outer shell, and a secondary bellows unit disposed between an inner surface of the inner shell liner and the head of a person wearing the protective helmet.

Abstract: A protective helmet including an outer shell, a ridgeline recessed inwardly from the interior compartment of the helmet and protruding outwardly from the exterior surface of the helmet, padding disposed in the interior compartment of the, a facemask made from an ultra-high density high molecular weight polymer coupled to the helmet, and the facemask defines a flat region having a generally planar surface.

Abstract: A modular energy absorbing soft wall system consisting of a plurality of partially overlapping interlocking panel structures slidably mounted on anchors on the side surface of an elongated concrete roadway barrier or median. Each panel consists of a flexible core layer sandwiched between an front and rear high density plastic layer. The core layer consists of a plurality of vertically extending air chambers. An elongated top piece with a flat bottom and an arched top is secured to the top portion of the core layer. The bottom portion of the system rests upon intermittent supports which extend to the road surface. During a vehicular impact energy is absorbed when the plastic layers deform, the chambers collapse, and the trapped air in the chambers escape out apertures in the inner plastic layer and through the bottom of the rubber layer.
