Abstract: A method of block puncturing for turbo code based incremental redundancy includes a first step (1200) of coding an input data stream into systematic bits and parity bits. A next step (1202) includes loading the systematic bits and parity bits into respective systematic and parity block interleavers in a column-wise manner. A next step (1204) includes selecting a predefined redundancy. A next step (1206) includes outputting bits from the block interleavers in a row-wise manner in accordance with the selected predefined redundancy.

Abstract: According to a preferred embodiment of the invention, the folding storage assembly includes a first panel having first and second end portions, a second panel having first and second end portions, and a third panel having first and second end portions. The first panel is pivotally connected to the second panel. In addition, the third panel is pivotally connected to the first panel. The folding storage assembly is movable between an in-use position and a stowed position. In the in-use position, the first panel extends laterally from the second end portion of the third panel and the second panel projects upward from the second end portion of the first panel. In the stowed position, the first and second panels are positioned substantially flush with the third panel. Moreover, the storage assembly may include at least one fastening member for fastening the assembly to the front wall of a basket.

Abstract: A cartridge case closure plug for closing a cartridge case, enhancing plug reakup in the shortest time span after ignition of the cartridge, and substantially reducing plug mass to reduce the impact loads exerted on the projectile by the plug. The plug is cylindrically shaped and constructed of a polymeric foam which may be covered with an elastomeric coating to lower the permeability of the plug. The plug is provided with a forward face, a rearward face and an outer cylindrical surface. The forward face of the plug is furnished with a centered depression which allows for center blowout and breakup of the plug upon ignition of the propellant contained in the cartridge case. The rearward face of the plug is provided with a tapered cylindrically-shaped cavity which reduces plug mass and enhances plug breakup while reducing the impact loads on the projectile.
