  • Patent number: 5433132
    Abstract: A missile and launcher system that shields a missile from external electromagnetic radiation. Shielding is accomplished by separating the shielding system of the missile from the shielding system of its launcher system. Unique and separate shielding of the missile is accomplished by utilizing the missile launching enclosure. External signal isolation is accomplished by providing insulation on the interface cable between the missile and the launcher system to attenuate high frequency electromagnetic radiation signals. The present invention is implemented using an unconventional combination of technologies that includes the use of composite materials, vapor deposited conductive coatings, high frequency dielectric insulation filtering, and high frequency coupling of the radiation on the surface of the enclosure and the launcher system.

  • Patent number: 5042742
    Abstract: An apparatus for controlling an airborne vehicle (18) includes a guidance unit (28), remotely located from the vehicle (18), for generating frequency modulated steering and control signals. A signal conditioning circuit (38) within the vehicle (18) conditions steering and control signals from the guidance unit (28). An attitude position sensing circuit (56) within the vehicle (18) senses and generates vehicle attitude position information. A programmable microcontroller (70) within the vehicle (18) receives the steering and control signals from the signal conditioning circuit (38) and vehicle attitude position information from the attitude position sensing circuit (56), and generates flight commands for controlling the flight of the vehicle (18).
