  • Patent number: 7919418
    Abstract: A composite material which has excellent ballistic performance and has improved flexibility. Surprisingly, it has been found that a combination of poly(alpha-olefin) fiber and matrix resin provides these desirable product features. The resin matrix is a block copolymer of a conjugated diene and a vinyl aromatic monomer, preferably a styrene-isoprene-styrene block copolymer, that is applied as an aqueous composition. The fiber has a tenacity of at least about 35 g/d and a tensile modulus of at least about 1200 g/d. The composite has a total density equal to or less than about 100 g/m2 and a stiffness of less than about 2.5 pounds (1.14 kg) for a two layer structure of the composite, and a total areal density equal to or less than about 190 g/m2 and a stiffness of less than about 3.0 pounds (1.36 kg) for a four layer structure of the composite. The Peel Strength for a two layer structure of less than about 1.0 pounds (0.45 kg) for a two layer structure of the composite, and less than about 0.7 pounds (0.

  • Patent number: 7849497
    Abstract: Described herein are a method and system for analyzing the security of a computer network. According to various implementations, there is a device adapter associated with each device that has a significant impact on the security of the network (e.g., routers, switches, gateways, or “significant hosts”). The device adapter, which may be implemented as a piece of software executing remotely from the device, queries the device to determine what its security settings are (e.g., its firewall rules). The device adapter conducts the query using whichever form of communication the device requires (e.g., telnet, HTTP) and using whichever command set the device requires. Each type of device on the network has a software model associated with it. For example, there may be a router model, a switch model, a firewall model, and a gateway model. The model is made up of a series of rule sets. Each rule set includes rules that are derived from the configuration of the device (obtained by the device adapter).

  • Patent number: 7687412
    Abstract: Flexible ballistic resistant composite material that has improved resistance to pick-up of water and other liquids, the composite material comprising a plurality of non-woven fibrous layers. The fibrous layers are formed from a network of high tenacity fibers (aramid fibers, extended chain polyethylene fibers and/or rigid rod fibers). The fibers are embedded in a matrix of a thermoplastic polyurethane resin. Preferably, at least two adjacent fiber layers are oriented in a cross-ply arrangement with respect to each other. Flexible armor, such as body vests, are provided which are formed at least in part from the flexible composite material.

  • Patent number: 7629277
    Abstract: Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.
