  • Patent number: 7937780
    Abstract: Body armor for ballistic protection of a user's extremities preferably comprising right and left arm protection units and/or right and left leg protection units. The units include a ballistic protection material which preferably covers most of the user's upper arm, elbow region, lower arm, shoulder, upper leg, knee region, and lower leg except for ventilation zones preferably located on the inner portion of the upper arm and the inner part of the upper leg. The back of the knee is preferably covered by a protective flap.

  • Publication number: 20060191544
    Abstract: An nstrumented thoracic model for measuring the effects of impacts is provided. The model has simulated skeletal components, simulated tissue, simulated internal organs, and sensors that are optimally placed in the simulated tissue and organs, said simulated organs and said simulated skeletal components. Simulated human tissue is made of a modified ballistic gelatin, comprising ordinance gelatin, chilled water and an antimicrobial agent in a desired volume or weight percentage. The resulting mixture is then poured into a container or mold having the desired tissue shape, and then chilled until the mixture has set. Simulated lung tissue is made of the modified ballistic gelatin, but also incorporates nicrospheres to approximate the density and modality of the lungs.

  • Patent number: 6405600
    Abstract: A material test specimen design is taught for the determination of critical strain and stress states for multiaxial fracture. The objective of the specimen is to increase the amount of data obtained per specimen while retaining simplicity in testing procedure by using standard tension testing machines to generate the primary deformation of the specimen. The specimen, in conjunction with analytical or computational simulation, uses nonuniform deformation fields produced by secondary and tertiary strain concentrations to generate and track these multiaxial strain states to fracture. Typically, the primary deformation is uniaxial tension of a panel, the secondary strain concentration is a circular hole in the panel and the tertiary strain concentrations are areas of reduced thickness within the deformation field of the circular hole. Multiaxial strain ratios from −0.50 to −0.10 and control over fracture initiation sites may be generated by a test specimen design of the type taught by this invention.

  • Patent number: 5519278
    Abstract: A method for reducing and/or shifting stress in at least one outer end poon of an actuator made from a piezoelectric material. The actuator is affixed to a substrate by an adhesive bond and adapted to cycle between an expanded and contracted positions, which creates stresses in the actuator and in the bond. The method includes the step of doping at least one outer portion of the actuator with a metal oxide to reduce piezoelectric activity therein. In a preferred embodiment, the doped outer portion has a gradient composition varying from the maximum at the end of the actuator to essentially zero concentration at a point inward of the end. The system includes a doped piezoelectric actuator adhesively bonded to a substrate and electrodes attached to the actuator for receiving electrical energy, the actuator containing a metal oxide dopant in the outer portions thereof.
