Publication number: 20210244123Abstract: A helmet for protecting the head of a user. The helmet includes an outer shell, an inner shell having padding that contacts the head and a cavity formed between the inner and the outer shells, wherein the cavity is filled with a fluid such as air. The helmet also includes a plurality of resilient strands located in the cavity and affixed between the outer and inner shells, wherein an impact force on the outer shell causes the head to impact the padding with a reaction force that compresses the cavity. Compression of the cavity pushes fluid through the strands to increase fluid friction and alter a velocity of the fluid. This decreases the energy of impact and consequently reduces an amount of force transferred to the head thereby protecting the head from normal and shear force.Type: ApplicationFiled: April 26, 2021Publication date: August 12, 2021Inventors: Ali M.

Patent number: 7051600Abstract: A triaxial testing system of material properties having top and bottom joint assemblies that rotate about and move along a longitudinal axis in response to forces imparted by a testing machine. The joint assemblies are connected together by horizontal and vertical linkage assemblies. The horizontal and vertical linkage assemblies are connected to horizontal and vertical loading and clamping assemblies to thereby transfer in-plane and multi-axial loads from the testing machine and the joint assemblies to a material test specimen. The test specimen is rigidly clamped to the horizontal and vertical clamping assemblies. The bases and ends of the test specimen are shaped for clamping and axial loading. Rigid plates may be disposed over ends of composite test specimens for spatially stabilizing such specimens during testing. The test specimens may include devices to measure and record the axial and shear loads, displacement and strains imparted to the specimens during testing.Type: GrantFiled: December 14, 2004Date of Patent: May 30, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Paul V.
