A protective helmet is described comprising: an outer layer (1); an inner layer (5) for contact with a head of a wearer; and an intermediate layer (3, 4) comprising an anisotropic cellular material comprising cells having cell walls, the anisotropic cellular material having a relatively low resistance against deformation resulting from tangential forces on the helmet. The anisotropic material can be a foam or honeycomb material. The foam is preferably a closed cell foam. The helmet allows tangential impacts to the helmet which cause less rotational acceleration or deceleration of the head of the wearer compared to helmets using isotropic foams while still absorbing a significant amount of rotational energy.

Each year in North America there are approximately 175,000 non-contact ACL injuries. One of the main causes of these injuries is the rotational and translational forces created when a player makes a sudden change in direction or stops. Every athlete subjects their lower extremities to various forces that are unique to his or her mass, speed, and strength. These forces are affected by composition of the playing field surface, shoe sole design and construction, and other factors. Using these and other factors, the level of force at which injury is inevitable (pre-injury force) is determined and an athletic shoe is created which will provide a mitigating deformation induced by a particular athlete's pre-determined, pre-injury force threshold. A mitigating deformation of as little as 2 degrees can significantly reduce injurious forces. After the athlete has progressed through that particular force-generating movement, the shoe's sole instantly returns to its original shape.

An assembly and method for using a flexible tensile member as part of the rigging for a dragline bucket. The tensile member includes a stranded core surrounded by a separate armor layer. The armor layer assumes the form of a hollow cylinder having a substantial wall thickness. A significant gap is provided between the outward-facing surface of the stranded core and the inward-facing surface of the armor layer. This gap minimizes wear between the two elements during the normal bending and flexing of the tensile member. A first anchor is attached to a first end of the stranded core and a second anchor is attached to a second end of the stranded core. These anchors serve to transmit tension carried by the stranded core. A first end of the armor layer is also attached to the first anchor and a second end of the armor layer is attached to the second anchor.

The invention comprises a hydraulic pump, wherein wave energy is used to pump a fluid. The apparatus utilizes the oscillation of the free surface of a water column within a moon pool on a floating vessel to lift a floating pump unit. After reaching a peak elevation induced by a passing wave, the gravitational forces on the floater pressurizes and moves a fluid using structurally linked pistons within fixed cylinders on the vessel during the downward return motion of the floater. The pressurized fluid can then be used in a variety of applications including the generation of electricity via hydroelectric turbines.

The invention relates to the novel usage of shear-thickening and rheopectic non-Newtonian fluids as shock absorbers intended absorbing acceleration or impact via submergence of an object to be protected entirely into non-Newtonian fluid. Additionally, this invention relates to the novel usage of shear-thickening and rheopectic non-Newtonian fluids as shock absorbers capable of absorbing the force of impact or acceleration and effectively dissipating the force away from the object to be protected over an extended duration (greater than an instantaneous impact) more effectively than traditional shock absorbers.

The present helmet invention combines lightweight, impact absorption materials, force distribution structures, and means for affixing a facemask and straps to the helmet for reducing the risk of head injury. The internal construction of the helmet uses the combination of three or more elliptically shaped rings, each referred to as a “halo ring.” The halo rings are rigidly affixed to u-shaped torsion bars, and together form a cage. The cage covers areas of the head and skull vulnerable to injury, operating to disperse and thereby dissipate external impacts at any point where forces on the helmet's external surface are transferred to the ovoid-like cage.
