Problems solved by technology

it is an unfortunate and undisputed fact today that, over the course and duration of even an average human lifetime, one encounters many threatening situations and perilous circumstances which are potentially injurious, if not actually life endangering.
Clearly however, the degree of jeopardy to the body and life of a living human or animal subject will vary in severity and degree with each of these commonly occurring circumstances and risk categories.
Nevertheless, what is uniformly shared among all these unpredictable conditions and uncertain predicaments is the very real danger to life and limb caused by the penetration and subsequent shattering of solid objects and / or the direct physical impact of flying items or high velocity projectiles, regardless of how they came to be moving entities traveling at speed.

Abstract

The present invention is directed to structures, constructions and assemblies able and functional to protect living subjects from a range and variety of moving objects differing in size, volume, and overall shape; from projectiles traveling at many different rates of speed, and from the effects of exploding and / or advancing solid fragments moving at high velocity. More specifically, the present invention relates to protecting living human and animal subjects through the use of three-dimensional designed structures and assemblies which employ configured and dimensioned penetration-resistant plates prepared from laminated constructs comprising multiple individual layers composed of asymmetric composite materials. These penetration-resistant plates will protect living subjects from high velocity projectiles and fragments in both civilian and combat situations.More specifically, the invention relates to protecting subjects through the use of penetration-resistant prepared plates for use in a wide range and variety of erections, constructions and assemblies. As typical examples, the penetration-resistant plates can be used to great advantage as in the making of shatter-proof windows, doors, curtain wails, face masks, vests, flooring, helmets, tires, computer screens, television screens, housing, aircraft shelters / bunkers, boats, security vehicles, buildings, automotive, sport arenas, guard shields.

Description

CROSS-REFERENCE[0001]The present invention is a Continuation-In-Part of U.S. patent application Ser. No. 10 / 978,880 filed Jun. 29, 2004, now pending; which is a Continuation of International Patent Application No. PCT / US2004 / 043513 filed 22 Dec. 2004, now pending. The legal benefit and priority of these previously filed applications is expressly claimed.FIELD OF THE INVENTION[0002]The present invention is concerned generally with penetration-proof fabrications and constructions useful for the protection of living human and animal subjects from high velocity projectiles and explosion fragments in both civilian and military combat situations; and is directed particularly to articles, manufactures, and assemblies, constituted of configured and dimensioned plates which have been previously prepared as penetration-proof laminated constructs composed of asymmetric composite materials, and which are able to protect and defend living subjects from traumatic injury and / or deathBACKGROUND OF ...
