    Abstract: A method and system are presented for use in determination of the orientation of an aerospace platform with respect to a first rotation axis. A direction of a rotation rate vector of said aerospace platform within a lateral plane intersecting with said first rotation axis is measured and the measured data is analyzed to determine an orientation angle of said aerospace platform about said first rotation axis. While the aerospace platform is in a predetermined-dynamic state movement, a certain direction is determined by measuring a direction of the rotation rate of the aerospace platform within said lateral plane by a sensor assembly mounted on said platform and including at least one rotation rate sensor. An orientation of the platform with respect to said first axis is determined by determining a relation between said certain direction and said known direction within said external reference frame.

  • Publication number: 20120125092
    Abstract: Embodiments of the present technology are directed to systems and methods for measuring projectile muzzle velocity. A muzzle velocity sensor measures an acceleration as well as a set of events occurring within the barrel of the firearm upon a shot being fired. Using the measured data, a muzzle velocity is calculated. The muzzle velocity sensor is used externally to the firearm, requiring no changes to the firearm or the projectile.

  • Patent number: 8176670
    Abstract: A firearm steady-rest which is provided in a folded storage form which is incorporated as part of a rifle sling. The steady-rest may be deployed by folding it outward to provide either a V-shaped support configuration or a U-shaped support configuration whereby the upwardly extending distal ends of the support engage and support the firearm therebetween. The steady-rest may then be grasped by the operator's forward extending hand to provide maximum steadying of the firearm for sighting and shooting. A gravity deploying bi-pod leg set is also provided which automatically locks into position when fully deployed by a gravity slide lock.

  • Publication number: 20120085162
    Abstract: The invention relates to a method for determination of the muzzle velocity of a projectile (2) when it emerges from the firing barrel (1) of a shoulder-held weapon. In order not to weaken the firing barrel, it is proposed that a transmitter (3) for transmission of signals be arranged on the end face of the firing barrel (1) and that two sensors (9, 10), which are arranged at a distance d from one another, be arranged in or on the projectile (2) in order to detect the signals transmitted by the transmitter (3) and that these sensors (9, 10) detect a pulse on flying past the transmitter (3), and that the muzzle velocity for the projectile (2) be determined from the time difference between the pulses detected by the two sensors (9, 10).

  • Patent number: 8132351
    Abstract: Adjustable shooting rests and shooting rest assemblies are disclosed herein. In one embodiment, a shooting rest includes a rest assembly for supporting a forestock of a firearm. The rest assembly includes a base member and first and second upright members extending from the base member. A position of each of the first and second upright members is independently adjustable with reference to the base member. The shooting rest also includes a support assembly coupled to the rest assembly to move the rest assembly in a first direction and in a second direction. The first and second directions are in a plane generally transverse to a longitudinal axis of the firearm. The shooting rest further includes a base coupled to the support assembly.

  • Patent number: 8113045
    Abstract: This invention provides a shock mitigation means that attenuates the high frequency energy transmitted to the floating element of an inertial measurement unit (IMU) device in a cannon launched guided projectile or cannon launched munition improving the ability of the IMU to survive the extreme forces of such cannon launched environment. The invention utilizes a crushable foam mitigator located in the IMU device's housing to interfere and apply a compressive force to the floating element of the IMU device, plus a rubber pad attenuator element placed above the foam mitigator to further tailor the transmission of shock energy to the floating element in the IMU device.

  • Patent number: 8100003
    Abstract: A device is provided for recording transverse acceleration of a projectile longitudinally traveling along a barrel. Within the projectile, the device includes a base, a cantilever beam, a stylus and a medium. The beam longitudinally extends at a first end from the base. The stylus connects to a second end of the beam, being longitudinally opposite from the first end. The medium is rigidly fixed relative to the base and indicates transverse deflection extent of the second end onto the medium. The transverse deflection extent can be vertically perpendicular to the beam, and the stylus can permit deflection that is horizontally perpendicular to the beam.

    Abstract: A rifle recoil absorbing strap assembly for absorbing rifle recoil from a rifle, the strap assembly preventing the bruising of a shoulder when firing the rifle and without having to permanently mount the strap assembly on a target shooting bench, a table or a horizontal support member. The strap assembly includes an elongated, flexible, horizontal first strap member with adjustable and releasable fastener. The adjustable and releasable fastener is used for securing together a first end and a second end of the first strap member. Also, the strap assembly includes a flexible, vertical second strap member with a first end and an opposite second end. The first and second end of the second strap member are adapted for receipt around a front portion of the rifle and secured thereto for preventing upward movement of the rifle when firing. Further, the strap assembly includes a rifle butt cradle adapted for receiving and securing a rifle butt of the rifle therein.

  • Patent number: 8047070
    Abstract: An apparatus and method for estimating a roll angle of a projectile may include a measurement unit outputting roll rate, yaw rate, and pitch rate signals indicative of rotation rates about substantially orthogonal roll, yaw, and pitch axes, the roll axis substantially aligned with a longitudinal axis of the projectile. A controller may sample the roll rate, yaw rate, and pitch rate signals to obtain time sequential roll rate, yaw rate, and pitch rate samples; calculate time sequential cumulative roll estimates by summing the roll rate samples; calculate time sequential gravity vector estimates from the corresponding yaw rate and pitch rate samples; de-roll each gravity vector estimate based on the corresponding cumulative roll estimate; filter the de-rolled gravity vector estimates to determine a filtered initial roll estimate; and add the filtered initial roll estimate to the current cumulative roll estimate to provide a current roll angle estimate.

  • Patent number: H2265
    Abstract: A differential variable reluctance transducer (DVRT) is provided to measure a translation parameter, such as acceleration and/or deceleration of a test projectile. The DVRT, contained in a canister of the projectile, includes a cylindrical housing and an electronics module. The housing defines a cavity containing insulation and a bobbin around which a wire coil is wrapped. The housing has an attachment end and a distal end that faces the acceleration indicator. The bobbin is disposed substantially collinear to the housing. The wire coil is helically disposed around the bobbin. The insulation fills the remainder of the cavity. The electronics module receives electric current from the wire coil and connects to a data recorder.
