Sensor technology developed by Southwest Research Institute has been named one of the 100 most significant technological achievements by R&D Magazine.

Southwest Research Institute (SwRI) created an underwater cave-mapping sensor that has the capability of traveling down a cave to gauge the path, dimensions and morphology of the tunnel. SwRI officials say these remote neutrally buoyant sensors work by injecting a dye in the water that can be used to determine the path and travel time of water through caves. The sensors are designed to float through the cave or conduit to measure the path by using an array of ultrasound sensors.

Local scientists say cave diving is extremely dangerous and is limited to large passageways, relatively shallow caves and limited distances.

“The information captured from these sensors is critically important for water-resource management and geotechnical risk assessment,” says Ronald Green, a scientist in the geosciences and engineering division at SwRI and a principal developer of the sensor paperless payday loans. “Adequate management of karst aquifers requires knowledge of water flow through caves and conduits, including location, size and morphology of the complex interconnected voids.”

SwRI officials say there could be applications in pipelines or sanitary sewers. Also, there could be future applications in flooded underground mines, tunnels or conduits that are not safe for manned entry.

San Antonio-based SwRI is an independent, nonprofit applied research and development organization. It has more than 3,200 employees and an annual research volume of more than $564 million. The institute has won 35 R&D 100 Awards since 1971. SwRI will accept its 2010 R&D Award Nov. 11 in Orlando.
