A -- NONDESTRUCTIVE MATERIAL CHARACTERIZATON SOL Cbd1499 DUE 041399 POC Paul Grahovac WEB: Idaho National Engineering & Environmental Laboratory, http://www.inel.gov/procurement/litco/index.htm. E-MAIL: Paul Grahovac, pg2@inel.gov. A -- Nondestructive material characterization. U. S. Patent Number 4,995,260. This is a potential technology development and licensing opportunity with Lockheed Martin Idaho Technologies Company (LMITCO), the prime operating contractor for the Department of Energy at the Idaho National Engineering and Environmental Laboratory (INEEL). In conventional technology for nondestructive material characterization., the large electrical signal required to generate the ultrasonic waves causes several problems in the design and construction of the piezoelectric (PZ) transducer and associated electronics. These include limited dynamic range, poor control of the signal shape, and a poor resolution of echoes which return to the PZ transducer a short time after the pulse. This patented technology replaces the induction of stress waves with an electrical signal induced by a laser pulse. The primary advantage of this device is that the receiving electronics do not have to be electrically isolated from the initiatingpulse, since the usual large electrical potentials are not present. This means the electrically noisy input diodes commonly used to reduce the pulse to acceptable levels in the receiving amplifier are eliminated. As a result, the dynamic range of the receiving amplifier is increased. LMITCO is seeking a written indication of interest from industry partners interested in funding a collaborative technology development project and/or entering into a license agreement for the purpose of developing and commercializing this technology. License terms will include an up-front licensing fee and a running royalty based on a percentage of sales. This is not an opportunity to provide goods or services to LMITCO or the Department of Energy. This Request for Interest (RFI) will close to response 30 days after publication. Interested parties should send e-mail to pg2@inel.gov (Paul Grahovac, Account Executive, Technology Transfer Office, LMITCO).
