Vibration controls, materials sensor, smaller antennas, and a book bag
The remaining patents are for a range of products developed by researchers in the Colleges of Engineering, Science, and Architecture and Urban Studies.
The "Active-Passive Absorber for Vibration and Sound Radiation Control (6,700,304)" was developed by Virginia Tech Mechanical Engineering Professor Chris Fuller and Pierre Cambou of Lyon, France, who received his Virginia Tech master's degree in mechanical engineering in 1998. The distributed vibration and sound dampener can be used in both a passive and active mode in a lightweight, conformal configuration. It is suitable for use in aircraft, automotive, and other applications with vibrating panel like structures. It is licensed to ESI/Vibro-Acoustic Sciences and NEVA Associates.
An "Apparatus and Method for Volumetric Dilatometry (6,718,281)" was developed by Virginia Tech Chemistry Professor Herve Marand and graduate students Paul Duncan of Vienna, Va., in electrical and computer engineering, Sean Christian of Woodbridge, Va., in chemistry, and Kevin Shinpaugh of Blacksburg, Va., in aerospace and ocean engineering. The High Precision Dilatometer enables very accurate measurement of the volume and/or density of solid materials as a function of time or temperature. It offers increased precision and accuracy of measurement based on the interference of light waves, Marand said. "Such equipment is of great use in materials research," he said. It is licensed to Airak of Ashburn, Va., a company started by Duncan while he was a student. Duncan, who is president of Airak, will receive his master's degree in 2005. Christian is chief operating officer at Stellar Net of Tampa. Shinpaugh is director of research and cluster computing at Virginia Tech.
