Abstract: A padded injury reducing non slip pool decking has an expanded polypropylene substrate as a core with its surfaces and a coating upon the surfaces adhered following skiving upon the surfaces. The present invention seeks to reduce slip injuries around a pool by providing a padded surface. The padded surface attenuates impact forces that occur when a person falls, or a body part of a person, hits the deck. The present invention provides a cushioning action that has increased energy absorption properties over the existing surfaces around swimming pools. The core utilizes expanded polypropylene melted from its pellet stage into generally slab form with a polyurethane coating. The coating has a precise mixture of three components and various additives. The components include methylenebis and isothianzolin and the additives include traction, tints, among other things.

Abstract: A hard soft ballistic armor has an armor panel with continuous and contiguous hard zones and soft zones providing seamless, gapless fragmentary and ballistic protection to a wearer. The panel comes from a process of pressing UHMWPE panels into hard armor with soft, flexible joints or panels of soft construction into hard panel with a defined shape. The present invention through its processes provides a single or plurality of heated, hard pressed areas and unheated, unpressed areas in the same piece of armor where the soft areas remain flexible. The processes of the present invention apply high and low pressure simultaneously to layers of material resulting in armor panel having a three dimensional shape that fits a portion of the body of a wearer.

Abstract: A blast deflecting boot has a V like shaped sole, a layer to reduce and to stop high velocity fragments, a padded core that limits the blast forces transmitted to the lower leg of a soldier, and an upper of high velocity blast fragment reducing fabric. The invention provides the sole within a layer of non-slip urethane that contains energy absorbing foam, a layer of high velocity fragment reducing para-aramid or ultra-high molecular weight polyethylene UHMWPE fabric, and a core of closed cell single or multiple density high energy absorbing foam or silicone that absorbs impact forces. The insole has a high velocity fragment reducing layer system of multiple layers of UHMWPE, or para-aramid. The sole of the present invention may have a unitary form or be assembled from multiple sections.

Abstract: A tibia force reduction wedge has a core, a coating upon the core, and fasteners upon the coating. The core has three surfaces forming a triangularly shaped cross section and two opposite spaced apart ends. The core has single or dual density closed cell energy absorbing expanded polyethylene. Following skiving upon the surfaces, the coating adheres to the exterior of the core. The invention has an anti fungal, non slip, polyurethane coating. Hook and loop fasteners mutually engage fasteners upon an existing surface of a vehicle deck for adjustment to the leg lengths of vehicle occupants. The wedge sees usage beneath seats inside a vehicle.

Abstract: A video encryption/decryption system in which lines of video information are stored in digitised form in a block of RAM memory, and are typically shuffled in groups of 32 lines by pivot reading information corresponding to 32 lines from the memory in a first predetermined order, which may for example be sequential order, and writing new input line information into the corresponding locations, and then reading from, and writing to, the memory in a second different order which may be random or pseudo-random, and subsequently repeating these two read/write operations alternately. This enables the line shuffling process to be achieved with a reduced memory requirement, compared with known methods.
