Abstract: An energy-absorbing “smart” bumper system features a variably controllable valve which is responsive to impact conditions. The initially closed valve opens upon maximization of the pressure reading upon the bumper, and maintains the same open setting (in other words, the same valve area) during such period of pressure maximization. During the succeeding period of pressure declination from maximum, the valve undergoes ongoing adjustment of its open setting (in other words, ongoing adjustment of its valve area) so that the reaction force of the bumper remains constant. The valve closes (in other words, the valve area becomes zero) when the pressure falls abruptly toward zero (an occurrence which correlates with a similar plummet in reaction force, as well as with near or approximate motionlessness of the impacting body), thereby avoiding or curtailing an unwanted rebound effect.

Abstract: A bridge pillar debris deflection apparatus (10), which attaches to a pillar supporting a structure located on a water way, such as a river or ocean. The apparatus (10) deflects debris to maintain the pillar clear from any unwanted build-up of rubbish. The apparatus utilizes at least one finned cylinder (30) that is rotatably held in place in front of a pillar (50) with an upper attachment bracket (26) and a lower attachment bracket (28). The cylinder is rotated by the force of the water impinging on a multiplicity of fins (44) extending from the outer surface of the cylinder to deflect the debris and prevent any accumulation. An axle (38) is positioned between the brackets and extends through the cylinder in the preferred embodiment. Any number of cylinders may be used in tandem, according to the need and environmental conditions.

Abstract: The impact absorption system uniquely features arrangement of composite structures which include fiber-reinforced high strain-to-failure viscoelastic matrix material. According to many embodiments, a gravitationally or buoyantly suspended hollow fiber-reinforced urethane reaction bumper is closely and anteriorly situated with respect to fiber-reinforced urethane tension tubes which are secured at the ends and disposed in an approximately vertical plane. In operation, an incoming marine vessel impacts the bumper which in turn impacts the tubes. The invention takes advantage of the great deformability, high energy absorbency and other beneficial properties of fiber-reinforced high strain-to-failure viscoelastic matrix material. Moreover, applicability/adaptability of individual bumper systems to varieties of marine vessels is made possible through analysis and arrangement/rearrangement/exchange/interchange of structural components.

Abstract: An acoustic buffer has a pair of inflatable cylinders that float in the water against the hull along the waterline around the bow of a boat to dampen noise of the water lapping against the hull when the boat is anchored. The cylinders are joined together by Velcro strips at the forward ends adjacent to the bow, and each cylinder extends toward the stern along the hull. The aft ends of the cylinders are tied to boat cleats in order to hold the cylinders snug against the hull. Each cylinder has a second inflatable internal cylinder. The inner cylinder is filled with water and the outer cylinder is filled with air by means of valves in the aft ends of the cylinders. The flotation levels of the cylinders may be adjusted by varying the amount of water in the internal cylinders. The buffer may be thereby adjusted to optimally dampen the noise from water lapping against the hull for various different hull designs and shapes.
