  • Publication number: 20030142005
    Abstract: A system for defeating a threat posed by a guided missile. The system includes a broad band light source with a beam width of less than 4°, a DIRCM control system, a missile warning system, and a missile tracking system. The DIRCM control system is configured to aim a beam produced by the light source. The missile warning system is configured to supply the DIRCM control system with a first trajectory of the missile. The missile tracking system is configured to supply the DIRCM control system with a second trajectory of the missile, which is more accurate than the first trajectory.

  • Patent number: 5339690
    Abstract: An apparatus for measuring the rate of rotation and linear acceleration of a moving body in two perpendicular axis (X and Y). The rate of rotation is determined by measuring the force resulting from the Coriolus effect and the linear acceleration is determined by measuring the resulting force in the axis of acceleration. The apparatus includes an integral flexing unit which during rest extends in the Z axis, having a flexure zone with two degrees of flexing freedom. A proof mass is resiliently mounted on the flexing unit remote from the flexure zone with one degree of oscillation in parallel to the Z axis. The proof mass is caused to oscillate at constant amplitude by suitable electric means whereby, upon rotation of the body or linear acceleration thereof, the flexure unit oscillates by periodic bending of the flexure zone and the extent of flexure which is proportionate to the rate of rotation and/or linear acceleration, is determined by suitable electro optical means.

  • Patent number: 5142485
    Abstract: A new two-axis accelerometer comprising a rotating body linked to the motor rotor via a flexure zone. In a first type the rotating mass is concentrated and the flexure zone permits the rotating mass to perform a transversal parallel shift. In a second type the rotating body is an inertia rotor and the flexure zone is an extension of the rotor shaft that embodies a flexible portion. In either type the rotating body/flexure zone combination has two degrees of flexing freedom with two different flexure coefficients in two mutually perpendicular directions both normal to the electric motor shaft. The accelerometer further comprises a deflector shaft coaxial with the rotor shaft and extending beyond the rotating body and associated with electro-optical measuring means and processor means for measuring linear acceleration components in said two mutually perpendicular directions.
