BaroBall: Control Valve with Volume Flow Measurement

Barometric pumping is a remediation technique that removes volatile contaminants from soil in the vadose zone, above the water table. The BaroBall control valve increases the efficiency of barometric pumping and allows natural soil gas to flow out of an underground well, while restricting air flow...

Cellulose-based water sensing actuator

An integrated water sensing actuator is based on a fibrous cellulosic material having anisotropic moisture-absorbing properties such that it's dried-in strain is greatest along one axis thereof. A plug of the dry and compressed fibrous cellulosic material has a powder material coated thereon and...

Collapsible wet or dry submersible vehicle

A submersible vehicle's hull has an outer wall that is at least partially constructed of a multi-wall fabric having a sealed space between at least two walls thereof. The sealed space is controllably filled with one of air, water, and a combination of air and water in order to control the buoyancy...
