Abstract: A system is provided for detection of surface glints on a water surface. A laser of the system produces a nearly horizontal or vertical linearly polarized laser light pulse. Lens of the system form an afocal imaging system with lateral magnification and longitudinal magnification that projects an image of the laser light at a pulse location onto the water surface. A portion of the laser light is focused onto a high speed detector. The output of the high speed detector is connected to a digitizer to provide system synchronization and to monitor the laser light. A glint image of the pulse location is detected by a broad band detector. The electrical output of the detector is input to the digitizer where the output is digitized. The output of the digitizer is then sent to a computer where the output is stored and analyzed.

Abstract: A method for actuating an inertial igniter. The method including: moving a mass contained within an interior of a body towards one of a pyrotechnic material or primer when an all-fire acceleration profile is experienced; hermetically sealing the interior of the body from an outside environment; restraining the movable mass from contacting the one of the pyrotechnic material or primer for acceleration profiles less than the all-fire acceleration profile; at least indirectly blocking the movable mass from movement towards the one of the pyrotechnic material or primer under acceleration profiles equal to or greater than the all-fire acceleration profile; and manually removing the blocking such that the movable mass can move towards and contact the one of the pyrotechnic material or primer when the all-fire acceleration profile is experienced to actuate the inertial igniter.

Abstract: A method and system of disabling a remote improvised explosive device (IED) that is triggered by a cell phone. A portable wideband network system, installed in a vehicle, is used to determine operator frequency or frequencies active on a route along which the vehicle will travel. The vehicle includes a wideband transmitter for raising a radio frequency noise floor across all of the active cellular frequencies in a limited area surrounding the portable wideband network system during passage along the route. A notch filter is used by the system for filtering a particular frequency from the noise floor. The power level of the portable wideband network system is increased so that the strongest signal at the particular frequency in the limited area is provided by the portable system's base station. All mobile terminals in the limited area around the vehicle are connected to the portable system and the portable system prevents call completion of any of the connected mobile terminals.

Abstract: A plasma antenna generator includes an ionizable material, an explosive charge capable of projecting the ionizable material upon detonation, and a detonator coupled with the explosive charge. An electromagnetic pulse transmitting system includes an electromagnetic pulse generator and a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator. A method includes providing an explosive device comprising an ionizable material, detonating the explosive device to propel the ionizable material, and ionizing the ionizable material to form at least one plasma trail. A sensing system includes an electromagnetic pulse generator, a plasma antenna generator capable of reradiating an electromagnetic pulse emitted from the electromagnetic pulse generator, and a sensing system capable of receiving and analyzing at least a portion of the electromagnetic pulse after being reflected from an interface.

Abstract: An active electromagnetic influence firing system has transmitter coils and eceiver coils mounted on a single warhead section. One set of receiver coils has vertical look capability for detecting surface ships and another set has 360.degree. look capability for detecting submarines. An influence electronics package automatically nulls out directly induced electromagnetic radiation and passes only the signature received from targets. Amplitude, duration, and frequency criteria implemented by circuitry in the influence electronics package determine whether there is a valid target.

Abstract: A fuze or igniter provided with an adjustable electronic unit (24), a separate energy supply (40) as well as a mechanical safety device (26). In order for this fuze to be independent of the weapons system and not be bound to a particular type of payload, the adjustable electronic unit (24) and the mechanical safety device (26) are accommodated in the essentially cylindrical, watertight housing (22) of a basic module (20) that has two end faces (28, 30). The energy supply (40) can be mechanically and electrically connected with the basic module (20). In the region of one of its end faces (28), the basic module (20) can be connected with either a programming device (136) in order to program in an ignition time and a sterilization time (desensitization time) or a payload (42) that is independent of the weapons system employed and is not ammunition specific.

Abstract: A pressure sensor for use with a sea mine for detecting the presence of a ssing vessel by sensing a change in ambient water pressure caused by the Bernoulli effect relating to hydrodynamic flow induced by the vessel's motion. The sensor emits a responsive signal which can be used alone, or with signals from other influence sensors (acoustic and magnetic), to determine when the sea mine shoud be exploded. The sensor provides for equal sensitivity independent of the ambient pressure of the water at various depths at which sea mines may be planted, and employs electrical filters to eliminate noise.

Abstract: A proximity fuze detects an approaching or attacking torpedo and responds ereto by timely detonating an explosive charge that effectively destroys the torpedo when it is within a predetermined lethal range.

Abstract: A proximity fuze system having a plurality of spatially disposed energy dctors, the response patterns of which overlap in such manner as to form an energy response "fence" for detection of an intruding object within a certain area. An explosive charge is also included in the system for disabling or destroying said intruding object, and a plurality of memories and gates are effectively connected between said detectors and explosive charge to effect the detonation thereof whenever said object is within such lethal range as to be sensed by predetermined pairs of said detectors.

Abstract: The invention disclosed is an anti-submarine moored mine for penetrating . The moored mine has an elongated streamline body with a heavy, strong forward hull structure that constitutes a forward penetrating means and a rearward chamber for housing an air braking means such as a parachute. The intermediate sections of the moored mine contain on specific chamber for housing an explosive means such as a warhead and a separate and distinct chamber for housing an inflatable buoyancy means used to fix the position of the moored mine in the water in the proximity of the target submarine.
