A body impact protection system includes an inner layer and an impact force dampening and defusing structure. The inner layer includes a material composition and is adjacent to a body part when the body impact protection system is worn. The impact force dampening and defusing structure is juxtaposed to the inner layer and includes a plurality of components. The components function to reduce pressure on the body part from an impact force on a layer by layer basis. Each layer of the system dampens and defuses the impact force such that, by the time it reaches the body part, it has been substantially attenuated and spread over a large area.

A 3D printed structure of an elastic material having a first wall and a second wall may be provided. In one implementation, the 3D printed structure may include a first layer having a first portion of a first wall part and a first portion of a second wall part. The first portion of the first wall part may include a primary structural layer and the first portion of the second wall part may include a first flexible layer. The 3D printed structure may also include a second layer having a second portion of the first wall part and a second portion of the second wall part. The second portion of the first wall part may include a second flexible layer. The primary structural layer and the first flexible layer may have a first rigidity and a second rigidity, respectively, the first rigidity being greater than the second rigidity.

A modular integration kit for a positioning system, like a positioning system on a vehicle, includes a configurable foundation plate, a dampened bolting structure, and a modular vibration isolation assembly. The configurable foundation plate is configured to attach to the positioning system. The dampened bolting structure is affixed to the configurable foundation plate. The dampened bolting structure is configured to attach a payload to the positioning system, like for attaching a payload of a rifle, an optic and/or a rocket launcher onto a positioning system of a vehicle. The modular vibration isolation assembly is arranged between the configurable foundation plate and the dampened bolting structure. The modular vibration isolation assembly is configured to dampen the dampened bolting structure from movements of the configurable foundation plate attached to the positioning system.

An energy absorbing lattice structure having a predetermined energy absorbing load vector, may include, in combination, a first lattice substructure comprised of a first set of interconnected struts, and, interwoven with said first lattice substructure, a second lattice substructure comprised of a second set of interconnected struts.

Padding materials capable of use as or incorporation into protective products, and methods of producing such padding materials. The padding material includes a base and an array of raised unit cells that individually protrude from a surface of the base so that the unit cells are spaced apart from each other. The base and the unit cells are formed of a cured polymeric material that contains fine porosity, and a substrate formed of a textile or fabric material is embedded in the base and permeated by the cured polymeric material.

A lattice structure and system for absorbing energy, damping vibration, and reducing shock. The lattice structure comprises a plurality of unit cells, each unit cell comprising a plurality of rib elements with at least a portion of the rib elements including a solid bendable hinge portion for converting energy into linear motion along a longitudinal axis of the respective rib element.

A flexible energy absorbing system comprising a material coated, impregnated and/or combined with a strain rate sensitive substance is disclosed. It is formed so as to define repeating adjacent cells, each cell having a re-entrant geometry such that, upon impact, the material locally densifies at the impact site.

An athletic footwear with improved midsole that is having a helical network. The helical network can morph itself under compressive force. The helical network is made from units of an hourglass shape geometry, each unit having an upper member and a lower member. Each unit is of a wireframe geometry that is integrated with adjacent units to form a networked layer. When an external pressure is applied to the networked layer, such as when the feet wearing the footwear land on a ground, the wireframe legs in the upper member and lower member twists for providing cushioning and resiliency.

An anti-impact device includes a first connector, an upper outer cylinder, a lower outer cylinder and a second connector which are sequentially connected, where a top of the lower outer cylinder is sleeved with the upper outer cylinder to be movably connected to the upper outer cylinder; an aluminum honeycomb and a magnetorheological buffer outer cylinder are arranged inside the lower outer cylinder, the aluminum honeycomb is arranged at a bottom of a lower end cover, a piston rod is arranged inside the magnetorheological buffer outer cylinder, a top end of the piston rod extends out of an upper end cover and is connected to a collision head, and the piston rod between the collision head and the upper end cover is sleeved with a return spring; and an electromagnetic coil is wound around the piston rod, a damping piston is arranged at a lower part of the piston rod.

An impact-absorbing structure that includes a plurality of interconnected cells forming a sheet, each cell having a sidewall and a longitudinal axis. Each cell may be configured to absorb energy through plastic deformation in response to an applied load, and a sidewall of at least one cell may include a geometric perturbation that is oriented in a direction that is not parallel to the longitudinal axis of the cell. The geometric perturbation may reduce the load required to cause plastic deformation of the cell.
