Abstract: Inertial measurement units (IMUs) and methods with adaptations to eliminate or minimize sensor error, offset, or bias shift are presented. More particularly, the IMUs and methods for gun-fired projectiles herein are particularly adapted to accurately measure forces and to prevent or minimize the error, offset, or bias shift associated with events exhibiting high g shock, and/or high levels of vibration, and/or rotation. Even more particularly, the IMUs and methods herein utilize novel IMU packaging adapted to prevent or minimize sensor error, offset, or bias shift, and recalibration adaptations and methods adapted to correct or reset the error, offset, or bias shift from such an event. The IMUs are adapted to provide accurate measurements prior to, during and after such event, and to provide continuous accurate measurements during flight of gun-fired projectiles.

Abstract: The present invention relates to projectiles and munitions, and more specifically to such in flight. More particularly the present invention relates to projectiles and munitions in flight equipped with one or more image sensors adapted for acquiring image data of the environment surrounding the projection or munition in flight. The present invention further relates to systems and methods for correcting or stabilizing motion effects and artifacts present in the image data related to the movement or motion of the projectile or munition in flight, including spin or rotation of the projectile or munition.

Abstract: A tribological debris analysis system alternately including a general purpose computer used in conjunction with an imaging device and an illumination delivery system, or a circuit board integrating an embedded processor with the imaging device used in conjunction with the illumination delivery system. The illumination delivery system includes a bypass conduit connected to the machine under evaluation, an optical flow cell, a pump for pumping a fluid through the optical flow cell connected to the bypass conduit, and a laser for illuminating the fluid flowing through the optical flow cell. The imaging device detects debris and sends information representative of the debris to the general purpose computer or the embedded processor. The general purpose computer or the embedded processor classifies the debris according to size, generates shape features of the imaged debris and identifies a type of object wear based upon the shape features.
