20090205415 | ROLL ORIENTATION USING TURNS-COUNTING FUZE - The present invention comprises a device for determining the roll orientation of a body with respect to a local fixed coordinate system or a predetermined reference vector. The device uses a measurement of an external magnetic field, such as the Earth's magnetic field, to determine a roll orientation reference with respect to the field or an uncompensated roll orientation. The uncompensated roll orientation is then adjusted according to a bias angle, such as an angular difference between the external magnetic field and a local fixed coordinate system, to determine the roll orientation of the device with respect to the local fixed coordinate system or a compensated roll angle. | 08-20-2009 |

20100326182 | METHOD OF PRODUCING MISSILE NOSE CONES - A method for producing a missile nose cone is disclosed. The method consists of manufacturing a first missile nose cone from a first lot of polymeric material and determining a first rupture value. The method further consists of manufacturing a second missile nose cone from a second lot of polymeric material and determining a second rupture value of the second missile nose cone. Both first and second lots of material are mixed into a test batch with one another based on their associated rupture values. An evaluation missile nose cone is then manufactured from the test batch and a determination is made as to whether the evaluation missile nose cone has a desired rupture value. If a desired rupture value is not obtained, then the mixing and evaluation steps are repeated. | 12-30-2010 |

The sensor may include a plurality of segments that at least partially surround the casing. In some embodiments, the segments may be separated from the casing due to pressure that the projectile is exposed to during launch. | 12-13-2012 |
20130305819 | SYSTEM AND METHOD FOR MEASURING PARAMETERS OF MOTION OF A PROJECTILE AS IT EXITS THE MUZZLE OF A GUN - A system and method for providing information regarding the trajectory of a projectile is disclosed. The system comprises two subsystems: a non-magnetic sleeve designed to fit over the barrel of a gun, with a series of rings of magnetic material disposed thereupon, and an onboard measurement and control system comprising at least one magnetic sensor and control electronics, located within a projectile. As the projectile passes through the sleeve, the magnetic sensors within the projectile produce signals as the projectile passes through the magnetic rings. From the time profile of the signals thus produced, the projectile's linear and angular muzzle velocities are determined. | 11-21-2013 |
