Abstract
Abstract A multi-layered composite comprising a protective layer, a retaining layer, a conductive layer and a filler layer intermediate the retainer and conductive layers. The filler layer is impregnated with liquid absorbent particles. A protective layer having specific characteristic for protection against extreme temperatures, physical impacts and the like is specifically disclosed for use in combination with the retainer, filler and conductive layers. The protective layer provides additional protection of the person from catastrophic events such as exposure of a person to fire and/or severe impact such as may be caused by gunfire.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
104 words
A multi-layered, liquid-retaining composite comprising: a conductive layer having an inner surface and an outer surface, said inner surface having a water proof, breathable coating whereby liquid is prevented from passing through said coating, but wherein air is permitted to pass therethrough; a filler layer impregnated with super-absorbent polymer particles and having a inner surface and an outer surface, said inner surface of said filler layer being in contact with the outer surface of said conductive layer; and a retainer layer having an inner surface and an outer surface, the inner surface of said retainer layer contacting the outer layer of said filler layer.
Claim 2
Dependent Claim
104 words
A multi-layered, liquid-retaining composite comprising: a conductive layer having an inner surface and an outer surface, said inner surface having a water proof, breathable coating whereby liquid is prevented from passing through said coating, but wherein air is permitted to pass therethrough; a filler layer impregnated with super-absorbent polymer particles and having a inner surface and an outer surface, said inner surface of said filler layer being in contact with the outer surface of said conductive layer; and a retainer layer having an inner surface and an outer surface, the inner surface of said retainer layer contacting the outer layer of said filler layer.
Claim 3
Dependent Claim
23 words
A multi-layered, liquid-retaining composite as set forth in claim 1 wherein the outer surface of said retainer layer is provided with protective means.
Claim 4
Dependent Claim
45 words
A multi-layered, liquid-retaining composite as set forth in claim 2 wherein said conductive layer, said filler layer and said retainer layer are attached to one another by seams in a generally quilted pattern whereby pockets are formed between said conductive layer and said retainer layer.
Claim 5
Dependent Claim
28 words
A multi-layered, liquid-retaining composite as set forth in claim 3 wherein said protective means is a fire resistant coating integrated with the outer surface of said retainer layer.
Claim 6
Dependent Claim
33 words
A multi-layered, liquid-retaining composite as set forth in claim 3 wherein said protective means is a discrete protective layer of fire resistant material in contact with the outer surface of said retainer layer.
Claim 7
Dependent Claim
41 words
A multi-layered, liquid-retaining composite as set forth in claim 3 wherein said protective means is a discrete protective layer, and, attachment means are provided for attaching said inner surface of said protective layer to the outer surface of said retainer layer.
Claim 8
Dependent Claim
39 words
A multi-layered, liquid-retaining composite as set forth in claim 6 wherein said attachment means is disposed for attachment and removal of said protective layer from said retainer layer without damage to either said protective layer or said retainer layer.
Claim 9
Dependent Claim
34 words
A multi-layered, liquid-retaining composite as set forth in claim 7 wherein said attachment means is a hook and loop means whereby said protective layer may be repeatedly attached and detached from said retainer layer.
Claim 10
Dependent Claim
21 words
A multi-layered, liquid-retaining composite as set forth in claim 8 wherein said protective layer is made of an impact resistant material.
Claim 11
Dependent Claim
50 words
A multi-layered, liquid-retaining composite as set forth in claim 9 wherein said filler layer is impregnated with liquid absorbent particles in a quantity sufficient to create an outward pressure within said pockets responsive to soaking in a liquid for a predetermined time so as to become an enlarged gelatin-like mass.
Claim 12
Dependent Claim
58 words
A multi-layered, liquid-retaining composite as set forth in claim 10 wherein said retainer layer is formed of a material having a predetermined porosity which permits said enlarged gelatin like mass to be forced through said retainer layer in response to an impact against said protective layer and to thereby reduce the effect of said impact upon a person.
Claim 13
Dependent Claim
31 words
A multi-layered, liquid-retaining composite as set forth in claim 11 wherein said protective layer is a rigid ballistic material configured to conform to the shape of the body of said person.
Claim 14
Dependent Claim
22 words
A multi-layered, liquid-retaining composite as set forth in claim 12 wherein said ballistic material is at least in part formed of "Kevlar".
Claim 15
Dependent Claim
46 words
A multi-layered, liquid-retaining composite as set forth in claim 13 wherein said liquid absorbent particles enlarge in size between 200 and 300 times from a dry size to a wet size responsive to soaking in a liquid for a period of between 15 and 25 minutes.
Claim 16
Dependent Claim
27 words
A multi-layered, liquid-retaining composite as set forth in claim 14 wherein the volume of each of said particles when dry is between 0.1 and 2 cubic millimeters.
