Abstract: A fluid containment apparatus with a floor and a side wall is provided. A wall support is included that supports the side wall and can be moved between an initial supporting position and a collapsed position. The side wall is movable from an initial containment position to a collapsed state to allow access for vehicles or other objects to the floor. The wall support and side wall are subsequently movable back to their initial positions. In some arrangements, the wall support is movable back to the initial supporting position from the collapsed position but is not movable beyond the initial supporting position. Additionally or alternatively, in other embodiments the wall support remains in the collapsed position until a returning force is applied to move the wall support back.

Abstract: A system and method for facilitating measurement of environmental conditions such as might be used in emergencies or other situational awareness applications. The method includes dispersing several networked nodes in a region, the nodes being coupled to one or more sensors, and then employing the one or more sensors to sense one or more environmental conditions and providing sensed data in response thereto. In a more specific embodiment, the region exhibits a fire, and the method further includes utilizing the sensed data to predict fire conditions, such as fire movement and temperature. A controller may be employed to selectively adjust power to one or more sensors based on predetermined priorities associated with sensed data output from the one or more sensors.
