Abstract

A method includes providing an article having an impact side and an asset side and exposing the impact side of the article to a plurality of pressure waves, the pressure waves having a plurality of pressure wave frequencies. The method also includes reflecting at least one composite harmonic of a portion of the pressure wave frequencies and reducing an amplitude of a portion of the pressure waves.

Claims

AMENDED CLAIMS
received by the International Bureau on 20 April 2018 (20.04.2018)
CLAIMS:
1. A method comprising:
providing an article having an impact side and an asset side;
configuring the impact side of the article to be exposed to a plurality of pressure waves; configuring the article to reflect at least a portion of the pressure wave frequencies; and configuring the article to reduce an amplitude of a portion of the pressure waves.
2 - 5. (Cancelled)
6. The method of claim 1 , wherein the plurality of pressure waves comprise a Shockwave, a fireball, or a combination thereof.
7. The method of claim 6, comprising exposing the article to the fireball, the fireball comprising at least one fireball wave.
8. (Cancelled)
9. The method of claim 7, further comprising cancelling a portion of the at least one fireball wave by reducing an amplitude of the at least one fireball wave.
10. The method of claim 9, further comprising absorbing a portion of the at least one fireball wave.
1 1 - 13 (Cancelled)
14. The method of claim 1, wherein an asset is located on the asset side of the article.
15. The method of claim 14, wherein a blast impulse on the asset is less than wherein the fireball had not impacted the article.
16. The method of claim 14, wherein a load on the asset is less than wherein the fireball had not impacted the article.
17. The method of claim 14, wherein a peak load on the asset is less than wherein the fireball had not impacted the article.
18. The method of claim 1 , wherein at least some energy of the plurality of pressure waves is dissipated within the article.
19. The method of claim 1, comprising changing a velocity of a ballistic projectile with the article, capturing a ballistic projectile with the article, or combinations thereof.
20. The method of claim 1, wherein the article comprises a single layer.
21. The method of claim 1, wherein the article comprises multiple layers. 22 - 32 (Cancelled)
A method comprising: providing an article comprising multiple layers, wherein each layer is coupled with adjacent layers of the article, wherein the article has an impact side and an asset side that is opposite the impact side, and wherein, from the impact side to the asset side, each successive layer has a density that is greater than a density of the adjacent layer that is closer to the impact side;
receiving at least one pressure wave on the impact side of the article;
reducing an amplitude of the at least one pressure wave; and
absorbing at least a portion of the at least one pressure wave with the article.
34. An article comprising multiple layers, wherein each layer is coupled with adjacent layers of the article, wherein the article has an impact side and an asset side that is opposite the impact side, and wherein, from the impact side to the asset side, each successive layer has a density that is greater than a density of the adjacent layer that is closer to the impact side.
35. The article of claim 34, wherein the article is a laminate.
36. The article of claim 35 , further comprising adhesive, wherein the adhesive mechanically couples adjacent layers of the article.
37. The article of claim 34, further comprising a frame mechanically coupled with the multiple layers.
38. The article of claim 34, wherein the article comprises at least three layers.
32
39. The article of claim 38, wherein the article comprises one or more layers comprising a natural or synthetic rubber, one or more layers comprising metal foam, and one or more layers comprising concrete.
40. The article of claim 39, wherein the article comprises one or more layers comprising a fiber composite.
41. The article of claim 34, wherein the article is a panel, a door, or a wall.
