Number	Title	Issue Date
8176834	Determination of weapons fratricide probability A method is provided for determining fratricide probability of projectile collision from a projectile launcher on a platform and an interception hazard that can be ejected or launched from a deployment position. The platform can represent a combat vessel, with the p...	05/15/2012
7253637	Arc fault circuit interrupter system In order to determine whether arcing is present in an electrical circuit, a sensor signal corresponding to current in said electrical circuit is processed. The sensor signal is filtered to determine the presence of noise in a predetermined frequency range and produc...	08/07/2007
7231862	Dual elevation weapon station and method of use A self-contained gimbaled weapon system (GWS) has a shared azimuth axis and two independent elevation axes for a sighting device and a weapon cradle. The GWS allows the weapon cradle to be elevated completely independent of the sighting device. The GWS can be stabil...	06/19/2007
7210391	Adjustable gun carriages Adjustable gun carriages are disclosed. An example gun carriage includes: a coarse height adjustment brake; a coarse side-to-side adjustment brake; a fine height orientation adjustment mechanism; a fine side-to-side orientation adjustment mechanism; a first control ...	05/01/2007
7207517	Munition with integrity gated go/no-go decision A munition is presented which includes an integrity verification system that measures the integrity of the munition. When an integrity threshold is not met, engagement of the munition with a predetermined target is aborted. Also presented is a methodology for gating...	04/24/2007
7174835	Covert tracer round A covert tracer round has an infrared emitter of radiation mounted to its front, side or back. The radiation (which may be coherent or incoherent) is detected by a sensor that displays an image of the target and the beam. The sensor receives the beam directly if the...	02/13/2007
7151656	Arc fault circuit interrupter system A system for determining whether arcing is present in an electrical circuit in response to a sensor signal corresponding to current in the circuit includes a circuit for analyzing the sensor signal to determine the presence of broadband noise in a predetermined rang...	12/19/2006
7136265	Load recognition and series arc detection using bandpass filter signatures A method and system for determining whether arcing is present in an electrical circuit includes sensing a change in an alternating current in the circuit and developing a corresponding input signal, analyzing the input signal to determine the presence of broadband n...	11/14/2006
7110101	Method and device for determining an angular error and use of the device A method and a device are disclosed for establishing actual changes and intended changes of the spatial angle of a main axis (e) of a sensor or effector attached to a receiver (4.1). The receiver (4.1) is directly rotatable around the first axis of rot...	09/19/2006
7068480	Arc detection using load recognition, harmonic content and broadband noise A method of determining whether arcing is present in an electrical circuit includes sensing a change in current in the circuit and developing a corresponding input signal, analyzing the input signal to determine the presence of broadband noise in a predetermined ran...	06/27/2006
5686690	Weapon aiming system A machine gun unit comprises a machine gun mounted to a support by a mounting permitting pivoting movement of the machine gun relative to the support in azimuth and/or elevation. Angle encoders provide position signals representing angular displacement of...	11/11/1997
5456157	Weapon aiming system A machine gun unit comprises a machine gun mounted to a support by a mounting permitting pivoting movement of the machine gun relative to the support in azimuth and/or elevation. Angle encoders provide position signals representing angular displacement of...	10/10/1995
5129308	Combat vehicle with extendible combat platform A combat vehicle utilization system including a plurality of extensible elevating members each adapted for mounting to a combat vehicle at a first end and carrying a combat platform at a second end is utilized to increase armament and effectiveness of a c...	07/14/1992
4744284	Device for limiting the field of fire in elevation on an automatic firearm A device for limiting the field of fire in elevation on an automatic firearm prevents the weapon from being fired when it is in certain, unsuitable positions. The weapon may not then be operated by either the electrical or the mechanical trigger. The oper...	05/17/1988
4470817	Apparatus for limiting the firing field of a weapon, particularly an armored cannon, during practice firing Apparatus for positioning the barrel of a weapon and limiting the firing field of a weapon to a predetermined target area. The apparatus comprises at least one stationary transmitter positioned in or adjacent the firing field and at least one directional ...	09/11/1984
