Abstract
A pneumatic module has an air passage formed therein, including an air inlet to receive a source of pressurized air, a first subsystem with an air splitter in fluid communication with the air inlet, a second subsystem, and a third subsystem. The air splitter is configured to create two unequal air pressure fields to deflect an airflow from the air inlet to the second subsystem. The second subsystem is configured to create two unequal air pressure fields to deflect the airflow toward a first air bladder to inflate the first air bladder, and when the first air bladder reaches a first threshold air pressure, a first backpressure from the first air bladder causes the second subsystem to switch and deflect the air flow to a second air bladder. A second backpressure causes the air splitter to switch and deflect the airflow from the second subsystem to the third subsystem.
