Patent ID: 8196357

Claim:
A portable barrier unit, comprising: a base; a top; a volume; wherein the volume comprises sidewalls, said sidewalls having a flexible diaphragm construction thereby defining an inflatable enclosed volume between the base and the top, said flexible diaphragm structure allowing variation of the vertical distance between said base and said top thereby varying a height of the unit; and the volume having a first inlet hole; wherein when said volume is inflated, the inflated volume will act as a barrier and wherein when said barrier unit is connected to another barrier unit, the units will form a barrier wall; and each barrier unit is independently connected and controlled in parallel to one or more medium sources such that one medium source is connected to all barrier units or each barrier unit is connected to its own medium source, thereby allowing various vertical height configurations of the barrier wall by independently varying each barrier unit; and the base and the top form a carrying case for carrying the volume; the case defining a second inlet hole that aligns with the first inlet hole of the volume.
