Abstract: An elevation structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having anti-decubitus ulcer capabilities as part of a mattress overlay system, in which multiple elongate, positionally adjustable, relatively moveable risers are configured for selective placement in conditions of transverse, subposed, under-engagement with the sides of an overlay to create substantially non-inclined, elevated, depth-supplemented regions at locations along the length of the overlay. The elevation structure and overlay may each include a dynamic-response core expanse formed of an open-cell, compressible viscoelastic foam coated with an elastomeric, moisture- and gas-flow-managing, differential-thickness coating structure load-transmissively bonded to the entirety of the outside of said core expanse to function as a dynamically-responsive unit therewith.
Abstract: A vehicle safety seat and related methodology featuring (a) an anti-spring-back seat platform having a generally upwardly facing support surface, (b) a triggerable acceleration structure disposed cooperatively relative to that support surface in a manner whereby the acceleration structure is operatively interposed that surface and any person occupying the seat, with this acceleration structure being triggerable to accelerate such a person generally upwardly away from the support surface, and (c) trigger structure responsive to the detection of a preselected downward deceleration of the seat platform to trigger the acceleration structure. A viscoelastic, acceleration-rate-sensitive cushioning structure is selectively interposed the acceleration structure and any seated occupant.
Abstract: A site-selectable, helmet-installable load-cushioning pad structure employable inside a helmet shell as a part of a plural-spaced-pad distribution featuring a compressible viscoelastic foam core which resists rapid, but not slow-movement, compression. Associated methodology includes the steps of providing such a structure for installation inside the shell of a helmet, and pre-arming the core of that structure with a load-response characteristics which (a) resists sudden-movement, rapid compression, yet (b) offers less resistance to slow-movement compression. An encapsulating moisture barrier layer may be provided around the foam core.

Abstract: Structure, methodology and performance involving and utilizing body armor strand material which includes an elongate strand body possessing elongate brittle ceramic surface structure, elongate ductile core structure disposed within that surface structure, and elongate brittle/ductile transition structure operatively interposed and joining the surface and core structures. Methodology includes the steps of preparing a defined mass of elongate ceramic-surfaced, ductile-cored strand elements, each including, along the outside of its length, elongate, sharp-angular edges, and placing that mass in the impact path of such a projectile in a manner whereby edges in the strands face the projectile impact path.
Abstract: A moisture-barriered, body-contact protective interface structure including a core, viscoelastic, acceleration-rate-sensitive cushioning structure, and a moisture-barriering container surrounding the cushioning structure, with the container being operable to block the flow of moisture while accommodating gas breathability for the cushioning structure.

Abstract: A self-seeking, load-distributing, load-balancing and shock-managing head-engaging system for use inside, and in association with, the shell of a helmet, including (a) a collection of configurationally changeable, shock-absorbing pads removeably and changeably attached/attachable effectively as a variable distribution to the inside of such a shell, and (b) a cinchable, self-seeking/adjusting, self-load-balancing and load distributing chin-strap subsystem operatively associated with the pad distribution, and also attached to the shell. This sub-system is sensitive to the then-particularities of such a pad distribution, and is operable, on cinching of the subsystem through the simple act of pulling on just two strap ends, to stabilize the associated helmet shell on the head of a wearer, with all of the pads in the then-distribution of pads being thereby drawn into proper, defined, shock-managing, load-distributing and load-balancing condition relative to the wearer's head.
Abstract: A stretchable-adjustable, cushioning helmet insert employable in the hollow, domed interior of a helmet shell. The insert includes a generally domed cap formed of a reversibly stretchable fabric, and adapted for installation within the interior such a shell, and cushioning structure in the form of plural, spaced cushioning pads positionally affixed to the inside of the cap in a manner whereby expansion and contraction of the cap causes spatial retreat and closure, respectively, of the spacings existing between each pad and its neighboring pads. This insert accommodates proper-fit the “insertion”, into a single-size helmet shell, of the different “effective” head sizes associated with a single user, such as a firefighter, who may, at certain times, be wearing no other headgear, and at other times, may be wearing auxiliary (and somewhat bulky) head-borne equipment, such as an oxygen mask.
Abstract: An impact-G-force, vector-modifying seat structure in a vehicle, which seat structure introduces, in a forward crash situation, and in a generally vertical plane, a special forward, then upward, and then rearward rotation of the base of the spine of a seated occupant. This motion tends to minimize crash injuries.
Abstract: A method for making a multi-layer helmet shell wherein inner and outer, structural, load-bearing semi-rigid layers are spray-deposited onto opposite surfaces of a pre-shaped, pliable viscoelastic, acceleration-rate-sensitive, microcellular foam core.
Abstract: A shock-load G-force minimizing seat structure which responds principally in non-springy compression, rather than in spring-loading bending, to vertically directed shock loads. The seat structure features an anti-springy frame structure which supports a thin and very lightweight seat cushion support spanner web formed preferably of a non-stretchy material, such as a material made out of elongate carbon-fibre strands.
Abstract: A plural-panel articulated (segmented) foldable/unfoldable (in a zigzag fashion) structure which can be unfolded and deployed in the form of a rectangular mat, and which can be folded to form plural other shapes, including a fully-folded shape which takes the form of a stack-cube of panels which is very compact in overall size. Each panel includes a central, anti-projectile barrier structure, and a cushioning foam structure, which offers features and advantages relating to fluid buoyancy, thermal insulation, and cushioning.
