a two way closed valve that blocks the air when it is de energized and allows air to flow in when energized in accordance with this embodiment of the invention valve 62 weighs about 1 3 oz and is about 0 75 u2033 in outside diameter and 1 3 u2033 in height furthermore each valve 62 threads to a corresponding station of manifold 60 manifold 60 includes a common inlet port 66 that allows the air to flow into the manifold a tube 66 is coupled from controller 50 to manifold 60 allowing air to flow in and out of the manifold 39 s main inlet port the two way switch in each valve 62 is powered externally via controller 50 control wires for each valve are coupled from the controller to each one of the valves in accordance with one embodiment of the invention a separate control wire can be directed from controller 50 to each one of the corresponding valves in an alternative embodiment a single control wire can be provided from controller 50 which is then coupled to a multiplexer such as 68 each of the valves is then connected to an output port of the multiplexer so that depending on the number of outputs set to u201c on u201d on the multiplexer the corresponding valves would be triggered to u201c open u201d or u201c close u201d as such when a valve 62 is in an open position air can flow from tube 66 into inlet 60 through valve 62 to a corresponding cellular bladder 14 causing the bladder to inflate when the valve closes the air inside the bladder is trapped and keeps the bladder in an inflated position again when the valve is opened and there is no air.
