CLAIMS

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1 . An impact mitigating membrane conformable to the surface of an object, comprising:

a laminar core, comprising:

a first lamina;

a second lamina coupled to the first lamina and configured to shift relative to the first lamina; and

a lubricating layer disposed between the first lamina and the second lamina configured to reduce friction between the first lamina and the second lamina;

a first encapsulating layer positioned adjacent the first lamina;

a second encapsulating layer positioned adjacent the second lamina; and

an anchoring attachment associated with the laminar core and coupled to at least one of the first encapsulating layer and the second encapsulating layer, the anchoring attachment configured to constrain relative lateral motion between the laminar core and at least one of the first and second encapsulating layers,

wherein the first encapsulating layer and the second encapsulating layer together surround the laminar core, and wherein the shift of the first lamina relative to the second lamina dissipates kinetic energy resulting from an impact force to the impact mitigating membrane, thereby reducing acceleration transferred to the object.

2. The impact mitigating membrane of Claim 1 , wherein the object is a portion of the human body or any protective equipment designed to protect a portion of the human body.

3. The impact mitigating membrane of Claim 1 , wherein the lubricating layer is selected from the group consisting of a gas, a liquid, a solid, a colloid, a ferrofluid, and combinations thereof.

4. The impact mitigating membrane of Claim 1 , wherein the first lamina and the second lamina are manufactured from elastic, stretchable, or rigid materials that are capable of elongation to the point of rupture when the impact force exceeds a threshold.

5. The impact mitigating membrane of Claim 1 , wherein the coupling of the first lamina and the second lamina is selected from the group consisting of mechanical fasteners, chemical fasteners, adhesive, buttons, elastic bands, rivets, fusion, thread, hook and loop, radio frequency seal, ultrasonic weld, thermal impulse seal, and combinations thereof.

6. The impact mitigating membrane of Claim 1 , wherein the first encapsulating layer is coupled to the second encapsulating layer by the anchoring attachment through an aperture disposed on the first lamina and the second lamina, the anchoring attachment selected from the group consisting of mechanical fasteners, chemical fasteners, elastic band, rivets, adhesive, buttons, fusion, thread, hook and loop, radio frequency seal, ultrasonic weld, thermal impulse seal, and combinations thereof.

7. The impact mitigating membrane of Claim 1 , wherein the first encapsulating layer is coupled to the first lamina by one or more fasteners selected from the group consisting of mechanical fasteners, chemical fasteners, adhesive, buttons, elastic bands, rivets, fusion, thread, hook and loop, radio frequency seal, ultrasonic weld, thermal impulse seal, and combinations thereof.

8. The impact mitigating membrane of Claim 1 , wherein the second encapsulating layer is coupled to the second lamina by one or more fasteners selected from the group consisting of mechanical fasteners, chemical fasteners, adhesive, buttons, elastic bands, rivets, fusion, thread, hook and loop, radio frequency seal, ultrasonic weld, thermal impulse seal, and combinations thereof.

9. The impact mitigating membrane of Claim 1 wherein the relative motion of the laminar core and at least one of the first and second encapsulating layers is laterally constrained by a tether on the first or second lamina, and wherein the anchoring attachment is coupled to the tether.

10. The impact mitigating membrane of Claim 9 wherein the relative motion of the laminar core and at least one of the first and second encapsulating layers is laterally constrained by the tether looped through one or more apertures on the first or second lamina.

1 1 . The impact mitigating membrane of Claim 6, wherein the coupling of the first lamina to the second lamina occurs at a perimeter of the laminar core.

12. The impact mitigating membrane of Claim 6, wherein the coupling of the first lamina and the second lamina occurs at a perimeter of an aperture.

13. The impact mitigating membrane of Claim 1 , wherein more than one laminar core is enclosed within the first encapsulating layer and the second encapsulating layer.

14. The impact mitigating membrane of Claim 1 , wherein the first encapsulating layer is integrated with the first lamina.

1 5. The impact mitigating membrane of Claim 1 , wherein the second encapsulating layer is integrated with the second lamina.

16. The impact mitigating membrane of Claim 1 , wherein the impact mitigating membrane is used in conjunction with protective equipment for portions of the human body, including head, neck, shoulders, upper arms,

elbows, forearms, wrists, hands, chest, back, spine, hips, thighs, knees, shins, ankles, and feet.

17. The impact mitigating membrane of Claim 1 , further comprising a permanent or coupling feature for attachment to protective equipment.

18. The impact mitigating membrane of Claim 1 , wherein a padded layer is integrated into the first and/or second encapsulating layers.

19. An impact mitigating membrane conformable to the surface of an object, comprising:

a laminar core comprising:

a first lamina;

a second lamina coupled to the first lamina and configured to shift relative to the first lamina; and

an aperture through the first lamina and the second lamina, the aperture configured to receive a fastener therethrough;

a first encapsulating layer positioned adjacent the first lamina;

a second encapsulating layer positioned adjacent the second lamina, the second encapsulating layer coupled to the first encapsulating layer through the aperture by an anchoring attachment for the laminar core to constrain relative lateral motion between the laminar core and at least one of the first and second encapsulating layers,

wherein the first encapsulating layer and the second encapsulating layer together surround the laminar core, and wherein the shift of the first lamina relative to the second lamina dissipates kinetic energy resulting from an impact force to the impact mitigating membrane, thereby reducing acceleration transferred to the object.

20. The impact mitigating membrane of Claim 19, further comprising a lubricating layer disposed between the first lamina and the second lamina configured to reduce friction between the first lamina and the second lamina, the lubricating layer selected from the group consisting of a gas, a liquid, a solid , a colloid, a ferrofluid, and combinations thereof.
