1991 - Electro-Optic Liquid Sensor
Developers: John W. Cary, Glendon W. Gee, Randy R. Kirkham, John F. McBride, Carver S. Simmons
This small, inexpensive device can be a water content meter or a leak detector for fuel oil, gasoline, solvents, or other organic liquids in soil, sand, cement, and other porous materials. An industrial firm has received a nonexclusive license to use the sensor to detect oil spills and leaks. The sensor also could be used to optimize crop irrigation.
