  • Patent number: 6098402
    Abstract: An Infra-Red suppression device composed of systems designed to alter the infra-red spectrum bands produced by the exhaust plume and airframe friction in order to render infra-red seekers, both active and passive, and infra-red homing missiles ineffective, therefore substantially increasing air-craft and crew survivability, and the BET or battle extension time.
    Type: Grant
    Filed: January 22, 1990
    Date of Patent: August 8, 2000
    Inventor: Stephen D. Sawruk
  • Patent number: 4942820
    Abstract: A fragmentation device includes a core of munitions in the form of a sphere. The sphere of munitions is surrounded by a spherical outer shell of a rubberized material. Further provide is a fuze at the surface of the internal rubberized material which is an electrical communication with a detonator which is embedded within the spherical core of munitions. The rubberized spherical shell is provided with spherically symmetrical fractures which radiate out from the core to insure a symmetrical dispersion of the force associated with the detonated munitions core.

  • Patent number: 4623355
    Abstract: A prosthetic axon for electrically bridging damaged nerve fibers constitutes a semi-conductive disc having therein pores substantially parallel to the polar axis of the disc, the pores having an interior coating of electrically conductive material extending substantially from the top to bottom surfaces of the disc, in which respective sides of the damaged nerve fibers are conductively secured to opposite sides of opposite pore ends of the conductive interior coating of the pores. The disc is embedded within a protein gel which is in electrical contact with both the conductive pore coating and the damaged nerve fibers.
