A sport helmet (10) for protecting a head of a wearer, such as a hockey, lacrosse or football player. The sport helmet comprises an outer shell (11) comprising an internal side (17) and an external side (19). The sport helmet also comprises an inner pad (15) mounted to the internal side of the outer shell for absorbing shocks when the sport helmet is impacted. The inner pad comprises a core of polymeric cellular material (60) and a covering (62) on the core of polymeric cellular material. The core of polymeric cellular material may comprise a body of expanded polymeric microspheres.

摘要:
An air isolation hand covering (10, 50, 120) has a bladder (11, 81, 124, 150, 160, 170, 180, 200, 220) consisting of a plurality of interconnected or independent inflation cells (85, 112, 210) that is positioned between the hand and a hand-held tool or other vibrating object. The cells (85, 112, 210) are oriented to permit easy bending of the hand covering (10, 50, 120) in directions appropriate for grasping an object. The effectiveness of the bladder in reducing the vibration energy transmitted to the hand is a function of the shape and configuration of the bladder, the pressure in the bladder, the compressible fluid used, the volume of the bladder, and the grip force and push force used when clasping a tool or other object. The bladder (11, 81, 124, 150, 160, 170, 180, 200, 220) can be filled with air or other fluid during the fabrication of the bladder or it can be inflated or deflated with a small pump (28, 128) and integral air valve (29, 134) connected to one of the air cavities (85, 112, 210).
摘要:
Venous compression in the neck reduced the extent of axonal injury in a standardized mild TBI model in rodents. The mechanism restricted brain venous drainage and increased the central nervous system blood volume and pressure, thus shifting intracranial physiology to the steep part of the volume-compliance curve. The lack of compliance inside the confines of the skull and spinal canal prevented slosh energy absorption and the resultant axonal injury by causing them to approach a more elastic collision when the skull was struck during the weight drop method. A first embodiment can be a device comprising a means to reduce SLOSH energy absorption in a fluid containing organism by reducing the flow of one or more outflow vessels of the cranium by compressing said vessels.

摘要:
An article of footwear with a midsole has an auxetic bladder member formed from inflated components surrounding star-shaped apertures. The inflated components form one or more auxetic bladders, and may have a triangular geometry. The inflated components are fluidly connected to adjoining components. Adjoining inflated components are hingedly connected, so that they can rotate with respect to each other in the plane of the midsole.
