Abstract: A hollow fibre membrane having a coiled, a hemihelix, a helical or an undulated native form, in which the membrane can be stretched by up to 4-times its original length with no plastic deformation, and wherein the native form of the membrane is produced by the asymmetric flow of liquid polymer through an opening of a die or nozzle.

Abstract: A method of autonomously tailoring a detonation delay time of a gun launched munition by utilizing target impact signatures including but not limited to a MOUT target set; earth and timber bunker, triple brick wall, double reinforced concrete, and light armor. While the present method is applicable to countless munition configurations, the projectile architecture used to develop the discrimination algorithm includes a tandem warhead configuration. Upon target impact the forward warhead detonates and pre-damages the target to allow the rear warhead to break through. Target impact data is used to set a detonation delay in the rear warhead providing increased performance behind the target.

Abstract: A computer program product corrects a detonation time from a ballistic table, based on the actual velocity of a projectile measured upon exit of the projectile from the gun tube. The computer program product transfers a 16-bit data stream, through a 16-bit to an 8-bit encoder, to a fuze controller implemented as an 8-bit platform, to provide precise timing adjustment to a fuze controller. The computer program product significantly improves the accuracy of detonation times for air burst mode. The encoder calculates the absolute truncated, square rooted, X, of the input time delay number, as well as the error correction number, Y. The encoder then transmits both numbers X and Y as an 8-bit data stream, optionally along with the parity data to the fuze controller.
