Jointly Owned Invention Available for Licensing

AGENCY: National Institute of Standards and Technology, Commerce.

ACTION: Notice of jointly owned invention available for licensing.

-----------------------------------------------------------------------

SUMMARY: The invention listed below is owned in part by the U.S. 
Government, as represented by the Department of Commerce. The 
Department of Commerce's interest in the invention is available for 
licensing in accordance with 35 U.S.C. 207 and 37 CFR part 404 to 
achieve expeditious commercialization of results of federally funded 
research and development.

FOR FURTHER INFORMATION CONTACT: Technical and licensing information on 
this invention may be obtained by writing to: National Institute of 
Standards and Technology, Office of Technology Partnerships, Attn: Mary 
Clague, Building 820, Room 213, Gaithersburg, MD 20899. Information is 
also available via telephone: 301-975-4188, e-mail: [email protected], 
or fax: 301-869-2751. Any request for information should include the 
NIST Docket number and title for the relevant invention as indicated 
below.

SUPPLEMENTARY INFORMATION: NIST may enter into a Cooperative Research 
and Development Agreement (``CRADA'') with the licensee to perform 
further research on the invention for purposes of commercialization. 
The invention available for licensing is:

[Docket No.: 98-020US]

    Title: Ultrasonic Strain Gage Using a Motorized Electromagnetic 
Acoustic Transducer (EMAT).
    Abstract: The invention was made jointly by scientists from NIST 
and the University of Colorado. The invention is jointly owned by the 
U.S. Government, as represented by the Secretary of Commerce, and the 
University of Colorado. The U.S. Government's interest is available for 
licensing. The invention comprises an ultrasonic strain gage using an 
electromagnetic acoustic transducer (EMAT). Stress causes a rotation of 
the pure-mode polarization directions of SH-waves and a change in the 
phase of waves polarized along these certain directions. The device 
comprises a rotating small-aperture EMAT, connected to a processor, to 
measure phase and amplitude data as a function of angle. The EMAT is 
placed on a work piece at the location where the stress is to be 
measured. The acoustic birefringence Beta is determined from the 
normalized difference of these phases. From these data, an algorithm 
calculates values of Beta and Phi. The work piece is then stressed or 
its stress state is changed. The values are measured again at the same 
location. Stress is determined from the change in Beta and Phi.
