- Description
- This is a sources sought synopsis. The National Aeronautics and Space Administration (NASA) contemplates holding a briefing on Monday, March 24, 2003 to discuss opportunities for the commercialization of its Hilbert-Huang Transform (HHT) in the analysis of machine health and acoustics. This award-winning technology provides a nondestructive method for monitoring and diagnosing operational machine health condition enabling you to avoid catastrophic equipment failures. Potential uses for the HHT in this application area include oscilloscope response to impulse propagation of sound through materials for analysis and identification, noise filtering to improve sound quality, and vibration analysis. Interested parties may have an opportunity to license the HHT under these applications. THIS IS NOT A PROCUREMENT. REQUESTS FOR A SOLICITATION WILL NOT RECEIVE A RESPONSE. The HHT Technology Briefing will be held in Greenbelt, Maryland. Registration and details regarding the specific location and agenda are provided at http://techtransfer.gsfc.nasa.gov/hht . Briefing participants will receive in-depth information regarding the technical capabilities of the HHT and have an opportunity to discuss the HHT technology with technical experts regarding the implementation of this technology to meet your unique requirements. One-on-one sessions will be conducted on the day of the briefing. All interested parties must submit their interest in attending the briefing, in writing, by Monday, March 17, 2003 to Ms. Lembo at NASA Goddard Space Flight Center, Code 504, Greenbelt Road, Greenbelt, MD 20771 or via fax at (301) 286-0301 or register through the website at http://techtransfer.gsfc.nasa.gov/htt . These submissions must include: (1) attendee name, (2) company affiliation, (3) company address, (4) company business, (5) areas of company research, and (6) place of incorporation. If you have any questions about this opportunity that you would like addressed during the briefing presentations, please forward your questions to the aforementioned individual to arrive by Monday, March 17, 2003. Background on the Hilbert-Huang Transform (HHT) NASA Goddard Space Flight Center (GSFC) developed this highly efficient, adaptive, user-friendly tool specifically for the analysis of nonlinear, non-stationary data--a difficult problem confronting many industries--as well as the analysis of linear and stationary signals. NASA?s Science and Technology Board recognized the HHT as ?one of the most important discoveries in applied mathematics in NASA history.? HHT has also won the Federal Laboratory Consortium for Excellence in Technology Transfer Award, NASA Space Act Award, R&D 100 Award and Government Executive Leadership Award, and its innovator has been elected a member of the National Academy of Engineering--the highest honor that can be bestowed to an engineer. Previous to HHT, there were no suitable methods to analyze nonlinear and non-stationary data. Unfortunately, few energy-frequency data sets, from either natural phenomena or artificial sources, are truly linear or stationary. Therefore, an algorithm was needed for these pervasive circumstances. The state-of-the-art HHT provides previously unavailable analysis of nonlinear and non-stationary data as well as linear and stationary data enabling better results and labor savings. The HHT algorithms are coded in C and accurately analyze energy frequencies via a three-step process: ?Sifting: Based on the empirical mode decomposition method, HHT's sifting process generates a collection of simple mode functions (SMFs) for the complicated data, allowing instantaneous frequencies to be defined. ?Hilbert transformation: Performing a Hilbert spectral analysis on the SMFs converts the energy-based signals to frequency- and time-based signals. ?Spectral presentation: The results are presented within the context of the Hilbert spectra. The HHT shows more physical meaning and enables users to conduct more precise analysis of signal data than can be obtained from conventional Fourier-based methods. Further, when used as a filter, provides sharper analysis than Fourier-based filters. This proven technology has been used to analyze under-water acoustic signals and several other commercial applications exist. This technology is part of NASA?s Commercial Technology Program, which seeks to stimulate commercial use of NASA-developed technology.
