Claim 10:
11. The inflatable barrier of claim 1, further comprising:
a foot switch external to the inflatable bag configured to at least temporarily reduce air pressure inside the inflatable bag; and
an air gate that comprises a tunnel between the front and the back;
and wherein:
the tunnel has a flexible circumference that allows the tunnel to fully collapse when no object is passed through and to partially collapse when an object is passed through or inserted, while hugging the object to stop airflow around the object;
the inflatable bag includes an air inflow tube at the back, wherein one end of the air inflow tube is coupled with the first opening and another end of the air inflow tube is configured to receive the air inflow from the air mover;
the first opening is reinforced with a mesh fabric and wherein the air inflow tube is restricted from bulging in one or more directions;
the inflatable bag includes a clear window on the front to hold and display information;
the inflatable bag includes a transparent window that allows visual contact from one side of the inflatable bag to the other side;
the inflatable bag includes a ballast container configured to minimize air gaps at the bottom; and
the inflatable bag includes edge hooks configured to minimize air gaps in case the inflatable bag deflates.
