Nathan L. Weber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System, method, and apparatus for improving the performance of ceramic armor materials with shape memory alloys
    Patent number: 8215222
    Abstract: Ring-shaped shape memory alloys put disk-shaped ceramic materials in a state of compression. The rings are radially deformed to introduce plastic strain into the rings. The rings are sized to closely receive the disk-shaped ceramic strike plates. When the assembly is heated, the rings attempt to regain their original shape and thereby put the ceramic strike plates into uniform, two-dimensional compression.
    Type: Grant
    Filed: August 22, 2007
    Date of Patent: July 10, 2012
    Assignee: Lockheed Martin Corporation
    Inventors: Brian T. Rosenberger, Craig A. Brice, Slade H. Gardner, Nathan L. Weber

  • System, method, and apparatus for forming ballistic armor from ceramic and shape memory metallic alloy materials
    Patent number: 7837086
    Abstract: A ballistic armor uses shape memory alloys and novel joining techniques to form a solution from a combination of shape memory metallic alloys (SMA) and ceramic materials. The SMA allows a high amount of strain to be recovered through a low temperature heat treatment. The amount of strain recoverable is much higher than that available through conventional thermal expansion mismatch solutions. Solid state or low temperature bonding methods are used to join the dissimilar materials. This joining technique avoids introducing excessive heat that would cause the SMA to transform before the armor system is assembled.
