Abstract: Barriers and methods of obstructing apertures. One embodiment provides a temporary barrier that includes a bag, a fluid source, and a shear thickening fluid. The bag is made of fabric and can expand (e.g. inflate) via the fluid source which is in communication with the bag. The shear thickening fluid permeates the fabric of the bag and has two states.

Abstract: Systems and methods are described for the use of an inflatable cushion (cargo cushion) that is capable of rapidly surrounding odd shaped cargo in a shipping container that enables the cargo to be secured during transportation without fear of damage to the cargo. The cargo cushion can be reused, if necessary (thereby preventing waste) and provides varying degrees of securement via adjustment of the inflation pressure and/or adjustment of the cargo cushion location in the shipping container. Because air can be utilized, the weight of the cargo cushion is nominal as compared to competing cargo securing systems.
