Abstract: Embodiments of the invention are directed to a soft shelter extension for use with a hard shelter where the hard shelter has a perimeter opening defined by a side wall and sealable by a deck rotationally coupled thereto, wherein the deck is prevented from over rotating by a pair of opposing cables linking the side wall to the deck. Such embodiments include a bow assembly having a plurality of bows wherein first ends are linkable to each other and second ends are linkable to each other, either directly or indirectly. These embodiments further include a pair of cable slide interfaces linked to respective first and second ends of the plurality of bows to receive the respective pair of cables. A flexible panel covers the bow assembly, and mates to the side wall and to the deck to form an enclosed space when the deck is rotated to a position wherein the cables are in tension.

Abstract: A selective material deposition treatment for flexible substrate to increase the coefficient of friction between the flexible substrate and a user, or article worn by the user. The material deposition treatment may rely upon the physical properties of the deposited material, such as the area, shape, density, topology or profile of the material, upon the mechanical properties of the material, or upon combinations thereof to enhance the friction of the substrate. Methods include identifying a pattern having a plurality of elements to be applied to the panel; identifying a desired coating composition to be applied to the substrate; and selectively applying the coating to at least a user contacting side of the substrate to generally recreate the pattern thereon. Uses for articles produced according to the methods include portable mattresses, pads, cushions, tent floors, technical outerwear, friction tape and others.
