Abstract: A blast reducing structure having a first web and a second web. Each of the webs having a first section defining a first plane, a second section defining a second plane, the second plane being generally parallel to the first plane, an interconnecting section interconnecting the first section to the second section. The first web is disposed in mirrored relationship to the second web to define a volume. An energy absorbing liquid is disposed in the volume, such that the first section, the second section, and the interconnecting section cooperate to collapse in response to an impact pulse, thereby dissipating force associated with the impact pulse. Alternate volumes may be air-filled so as to accept the expelled liquid.

Abstract: A lightweight tent for backpackers and like uses and characterized by a generally rectangular floor panel and a double layered canopy, the inner membrane of the canopy being breathable and the outer membrane being waterproof, these membranes being connected to opposite sides of the tunnel surrounding three sides of the floor and extended as an arch over the fourth side of the floor. The tunnel houses an inflatable tube which tends to straighten when inflated and this results in both membranes of the canopy being stretched in spaced relation to define an occupancy space having its greatest height dimension at said arch where a zippered closure flap permits access to the occupancy space.
