Posted on 10/11/2006 11:21:15 AM PDT by grandpa jones
Experimental testing has demonstrated that the system 100 is effective to defeat an AP bullet fired from a rifle at point-blank range (e.g. at impact V.sub.p.apprxeq.850 meters/second). Applications include, but are not limited to, body armor for infantry soldiers and law enforcement agencies, integral armor or armor appliques for vehicles such as aircraft, helicopters, and cars. Other uses include military applications, such as used in conjunction with ground vehicles or amphibious assault vehicles. Thus, the system 100 for protection against a projectile 105 having a speed, or velocity V.sub.p, comprises an accelerating layer 110, a plug layer 120, and (optionally) an energy absorbing layer 130. Typically, the plug layer 120 is planar to the accelerating layer 110 and the energy absorbing layer 130 is planar to the plug layer 120. The plug layer 120 includes at least one plug 140. These layers may be adjacent with perhaps an air gap between, but the same concepts could be applied to embodiments with intermediate layers. It is also possible to make the layers non-planar, such as for conforming or conformable clothing or other armoring.

And no trauma plate? That's pretty good.
The patent is from 2004. This is the basic idea behind Dragonskin armor. It's a bunch of small metal scales, basically.
This is what the patent protects:
1. A multi-layered armor for protecting a target against a projectile having a projectile velocity directed at the target, comprising:
an outer accelerating layer;
a plug layer adjacent the accelerating layer, the plug layer having an array of plugs; and
an energy absorbing layer adjacent to the plug layer;
wherein the accelerating layer is operable to initially receive the impact of the projectile, and to accelerate at least one plug of the array of plugs such that the plug thereby accelerated is in motion before the projectile strikes the plug;
wherein the plugs are made from a material different from the accelerating layer and after any plug is impacted by the projectile, that plug is operable to obtain the velocity of the projectile before the projectile perforates the plug;
wherein a projectile-plug combination is formed before the projectile perforates the plug, such that the projectile-plug combination increases the presented area of impact to an area greater than that of the projectile when the projectile-plug combination reaches the energy absorbing layer.
Interesting. I wonder what 62gr SS109 loaded to a bit over 2900fps would do.
Well, this vest might allow one to survive, but based on experience it's still serious "ouch" time.
A catcher's mitt for bullets. Cool.
Sorry, soldiers. You can't wear anything but official issue body armor. [Our buddies in procurement don't get their kickbacks when you buy *better than GI issue.*
But Law Enforcement can...
