Hello All;

NASA's Goddard Space Flight Center is considering holding a briefing on the
commercialization of a new algorithm for use in analyzing nonlinear
nonstationary data in health monitoring and acoustic data.  A quick glance
at the background material on the Hilbert-Huang Transform (HHT) looks like
it might be of interest to OEMs in ultrasonics and acoustic emission in
particular.  The announcement of the commercialization briefing follows.

Regards,
Chris

Title:           COMMERCIALIZATION OF HILBERT-HUANG TRANSFORM

Description:   SOL: 504
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.  All
