99--TECHNOLOGY TRANSFER OPPORTUNITY MAGNETORESISTIVE SENSOR BASED PROBE FORIMPROVED DEEP FLAW DETECTION AND SURFACE CHARACTERIZATION

NASA Langley Research Center in Hampton, VA solicits interest from companiesinterested in obtaining license rights to commercialize, manufacture and market thefollowing technology. License rights may be issued on an exclusive or nonexclusive basisand may include specific fields of use. THE TECHNOLOGY: NASA Langley Research Center has developed a novel probe for eddy current sensorapplications that improves detection depth and measurement resolution. Although the useof anisotropic magnetoresistive (AMR) sensors in eddy current probes to improvesensitivity at low frequencies and increase the detection depth is known, thehigh-frequency sensitivity and small size of these sensors is less explored. This newprobe incorporates two induction sources (i.e., one high frequency and one low frequency)and an AMR sensor; the result is improved resolution in near surface materialcharacterization, combined with simultaneous deep-flaw detection. Addition of a secondhigh-frequency induction source, oriented to produce a magnetic field orthogonal to thefirst, allows for near surface anomaly detection in two dimensions.To express interest in this opportunity, please respond to Sean Sullivan, ResearchTriangle International (RTI), at: NASA Langley Research Center, Strategic RelationshipsOffice (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton,Virginia, E-mail: [email protected], or phone: 757-864-5055. Please indicate thedate and title of the FBO notice and include your company and contact information.RTI is responsible for aggregating and acknowledging all responses. These responses areprovided to members of NASA Langleys Innovative Partnerships Office within the SRO forthe purpose of promoting public awareness of our technology products, and conductingpreliminary market research to determine public interest in and potential for futurelicensing opportunities. If direct licensing interest results from this posting, SRO willfollow the formal licensing process of posting in the Federal Register as required. Nofollow-on procurement is expected to result from responses to this Notice.
