- Description
- NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a deconvolution approach for the mapping of acoustic sources (DAMAS) that decoupled the array design and processing influence from the noise being measured, using a simple and robust algorithm. DAMAS does not add any additional assumption to traditional array processing/integration analysis. It merely extracts the array characteristics from the source definition presentation. In 2005, three-dimensional applications of DAMAS were examined. DAMAS was shown to render an unambiguous quantitative determination of acoustic source position and strength. The present development, called DAMAS-C, extends the basic approach to include coherence definition between noise sources. The solutions incorporate cross beamforming array measurements over the survey region. While the resulting inverse problem can be large and the iteration solution computationally demanding, DAMAS-C solves problems no other technique can approach. DAMAS-C is validated using noise source simulations and is applied to airframe flap noise test results. To express interest in this opportunity, please respond to LaRC-PatentLicensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/. These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development OSACB for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
