  • Patent number: 8751201
    Abstract: A process is provided for characterizing debris, such as predicted from a hydrocode model. The process uses simulation data currently from a CTH hydrocode system to generate a DATAOUT file, but can be easily modified to handle simulation data from other hydrocodes. The debris characterizing process completes iterative calculations to compare cell radii and determine cell connections. Cell connections are continually made to determine and characterize debris pieces. The process includes creating a dynamic scenario from the hydrocode model, producing a SPCTH file, translating the SPCTH file to a DATAOUT file, selectively eliminating materials from the DATAOUT file, reordering the input information in the DATAOUT file, determining connected cells to form single pieces of debris, storing connectivity in an integer array, storing piece information in a cell storage array; and displaying the debris information.

  • Patent number: 7921757
    Abstract: An armor plate is provided for a body jacket to include provision for electrical power. The plate includes a flexible substrate, a ceramic cover disposed on the substrate, and a battery. The cover includes cavities along the substrate, with the battery disposed within the cavities. The battery comprises sheets disposed within the cavities. The battery includes a first metal layer disposed on the substrate, an electrolyte layer disposed on the first electrode layer and a second electrode layer disposed between the electrolyte layer and the cover.

  • Patent number: 6945088
    Abstract: A multiple fragment impact test specimen, and a method for using it in multiple fragment impact tests against a target, is disclosed. The test specimen comprises two or more fragments fixed to one or more connecting members so that the fragments are held at a fixed distance apart during their flight to a target. The orientation and speed of the fragments at the moment of impacting the target are measured and the measurements are used to calculate the exact spacing and time delay between the individual fragment impacts. An experimenter can control the range of fragment spacings and time delays for a series of tests by choosing the lengths of the connecting members and thereby fixing the relative distances between the fragments.

  • Patent number: H1699
    Abstract: A thermal bond system is provided for bonding a first component that prods heat to a second component that dissipates heat. Carbon or other thermally conductive fiber tows are woven together to define a fabric mesh having first and second opposing woven surfaces. An adhesive bond that is flowable prior to drying is used to wet and cover the first and second opposing surfaces. The adhesive bond extends into interstices formed between adjacent fiber tows.
