  • Patent number: 7180302
    Abstract: A ceramic armor system with built-in conductive circuit attached to a ceramic component. The conductive circuit can be accessed by a user at contacts provided in the system. The circuit is arranged so that damage such as cracks that occurs within the ceramic component can propagate into the conductive material forming the circuit and thereby cause a rupture in the conductive circuit. An electrical probe such as an ohmmeter is used to measure the conductive circuit resistance that is then checked against an expected value. The results are used to determine if the ceramic armor component is in operable condition.

  • Patent number: 6517110
    Abstract: A dynamically deployed device shield (“DDDS”) including a cover, a loop shield, and a means for attaching the cover and loop shield to a vehicle structure. A dynamically deployed device (“DDD”) is contained in the loop shield and the loop shield is in turn contained in the cover. Upon deployment, a tear section in the cover separates and releases the loop shield and DDD. As the DDD expands and moves towards its location, the loop shield unfolds, guides the deployment of the DDD, and prevents the DDD from overshooting its final location. The shield also prevents the DDD from becoming caught on interior vehicle components and supplements the DDD with a larger protective impact surface. Optionally, a fabric shield is attached to the bottom of the DDDS to cover the area of a vehicle window below the deployed DDD and further increase the protective impact surface of the system.

  • Patent number: 6378897
    Abstract: A dynamically deployed device (“DDD”) assembly comprising a DDD, an anchor, and a mechanical stop, a vehicle member, a tether, or any other device that stops the rotation of the anchor. The anchor can be pivotally fastened to and stowed inside a vehicle structure member, with a DDD cord fastened to the end of the DDD anchor opposite the pivot attachment point. Upon deployment, the inflating DDD pulls the DDD cord tight. The DDD cord in turn pulls the anchor down such that the anchor rotates around its pivot attachment point and comes to rest against the stop, member, tether, or other similar device that stops the rotation. In this secured, locked position, the anchor provides a DDD attachment point offset from the vehicle structure member to which the anchor is fastened. Embodiments of the anchor include a link or cam.

  • Patent number: 6336656
    Abstract: A seat restraint system whose torso belt includes an inflatable structure that inflates upon impact to protect the occupants of a vehicle such as an automobile. The torso belt is secured to an anchor arm that is pivotally mounted on a side surface of a seat of the vehicle or a side structure of the vehicle. The anchor arm is rotationally biased to remove slack in the torso belt and locks up in the event of a vehicle crash or sudden stop. The inflatable structure is linked to a gas generator and crash sensor. The gas generator may be mounted in the seat or within the anchor arm itself. When an impact above a predetermined level of severity is detected, the gas generator is ignited, inflating the inflatable structure which contracts in length as it inflates. In a preferred embodiment, the inflatable structure is a braided tube. As the braided tube inflates, the diameter of the tube increases significantly and its length decreases significantly, due to the orientation of the fibers comprising the braided tube.

  • Patent number: 6332390
    Abstract: A ceramic composite tile armor which is reinforced at the more vulnerable joint and free edge areas, using glass or ceramic strips or overlays bonded with an adhesive to the outer surface of the tile joints and free edges. This reinforcement provides improved ballistic threat protection for ground vehicle, aircraft, watercraft, spacecraft, and body (personnel) ceramic tile armor applications. Glass or ceramic overlay strips assist in fracturing impacting projectiles that strike the tile joints or free edges. The substrate laminate backing can then capture fragments of the projectile and broken ceramic and prevent penetration. The invention provides improved protection over conventional joint and edge enhancements with higher reliability of accurate positioning over joint and free-edge areas, with less added weight, and at lower associated production costs.
