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.

Abstract: A vehicle safety restraint system for a vehicle that allows transfer of tensile force from a transferor belt to a transferee belt. One end of the transferor belt is secured to the vehicle and the other end is attached to a transferor plate. One end of the transferee belt is secured to the vehicle and the other end is fed through a transferee plate and attached to a tension transfer latch plate. During normal use conditions, the transferee plate and the tension transfer latch plate are united, the transferor plate and the tension transfer latch plate are engaged using a quick release mechanism, and the transferee plate is engaged in a buckle that is secured to the vehicle. When the vehicle experiences a sudden deceleration that exerts a tensile force on the transferor belt, the tension transfer latch plate is separated from the transferee plate if the tensile force exceeds a design value. When the tension transfer latch plate is separated, the tensile force is transferred to the transferee belt.

Abstract: A lightweight, ballistic resistant fabric armor constructed of multiple layers of high performance fiber woven fabric arranged in a quasi-isotropic orientation. The fabric armor is used in ballistic resistant garments to cover and protect vital portions of the human body. Used in a garment, the fabric armor is of minimal areal density and bulk while providing flexibility, freedom of movement, ventilation, and an inconspicuous appearance. The fabric armor meets many different global ballistic standards (e.g., the ballistic performance requirements of the National Institute of Justice Standard), with the number of woven fabric layers determined by the level of protection desired.

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.

Abstract: A system and method for deploying a belt-line inflatable structure with substantial axial tension, the system including an inflatable structure serial assembly held at its ends by two static anchors. The serial assembly can be independent inflatable structures connected together, or one continuous inflatable structure. One or more dynamic anchors, mounted opposite the static anchors, restrains the serial assembly at an intermediate portion of the serial assembly such that the serial assembly has a first axis between the one static anchor and the one or more dynamic anchors and a second axis between the other static anchor and the one or more dynamic anchors. The dynamic anchor(s) allow the serial assembly to move axially along the first axis and the second axis and to equalize the axial tension of the serial assembly along the first and second axes. The system can further include a shield covering the inflatable structures.

Abstract: A simple, low cost energy absorbing shear strip bender that provides constant load, tailored load, or adjustable load/displacement profiles for use in any application where a single use energy absorber is required. Examples include, but are not limited to: a spinal load attenuator for use in crash-resistant aircraft seats; crash-resistant aircraft landing gear; aircraft or automotive restraint harness attachments; cargo or high-mass item tie-downs; automotive bumper attachments; and collapsible steering columns. The present invention comprises a shear plate or other base material, a shear strip integral to the shear plate, and a shear strip tab, all of which are formed from a single sheet of ductile material. The energy absorber attaches to two objects and begins to displace when opposing forces applied to the shear plate and shear strip tab reach the design limit value such that shear strip shears and plastically deforms, i.e., bends.

Abstract: A flexible linkage system for connecting an environmentally sealed apparatus such as a parachute system to an external apparatus such as a parachute harness, the system comprising an internal link and an external link. The internal link is completely within the sealing packaging and is directly attached to the sealed apparatus. The internal link has a looped end wherein the sealing packaging is sealed around the internal link and joined in the center of the loop. A portion of the sealing is cut away from the center of the loop, thereby forming a void surrounded by the loop and the sealing material. The external link comprises a loop and a connecting hardware anchored to the external link. The loop in the external link is threaded through the center of the loop in the inner link and then it is connected to the connecting hardware.

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.

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.

Abstract: This invention is an Inflatable Tubular Bolster (ITB) which prevents or limits injury to an occupant of a motor vehicle due to a frontal or semi-frontal crash. In particular, the invention protects the front seat occupant's legs and lower torso by providing a cushioned barrier that absorbs impact energy and restricts the occupant's lower body from moving forward and into or underneath the instrument panel and toward the foot well. This invention can be effective in any vehicle where an occupant's lower body is subject to crash injury from a dashboard, instrument panel, or similar structure.

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.
