  • Apparatus and method to measure back face signature of armor
    Patent number: 9222864
    Abstract: An apparatus and method are provided for evaluating the backface signature of flat panel ballistic resistant composites with accuracy, repeatability and improved correlation to the expected backface signature of shaped ballistic resistant composites in actual field use. The apparatus separates the composite from a clay backing material with a suitable spacer so that the bulk of the backface deformation is inside an air gap space with minimal clay disturbance, thereby eliminating conventional testing error and producing an accurate test result.

  • Method to apply multiple coatings to a fiber web
    Patent number: 9200874
    Abstract: A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials.
