Hi again,
Well, Kryon has told us to look to the ways our own brains work for
the next advances in computer technology -- here is just
another example of how we're already doing that....

JPL Neural Network Chip Paves The Way To A Cleaner America As Ford Signs Licensing Agreement
A new computer chip that mimics how the human mind works is making its
way from the space program to American industry
and may end up in millions of American cars in years to come.
Computer scientists at NASA's Jet Propulsion Laboratory, Pasadena, CA,
have made advanced neural network technology
breakthroughs that can solve diagnostic problems in industries from
automobiles and aerospace to manufacturing and electricity
production.
JPL and the Ford Motor Co. have signed a licensing agreement for use
of an advanced neural network technology to diagnose
misfiring under the hoods of Ford automobiles, among its many potential
applications. With the advent of this new chip, vehicles
should show a reduction in emission levels.
The smart fit between JPL's neural net hardware and Ford's automotive
engineering algorithm expertise will enhance the
industrial giant's ability to meet ever-stricter Clean Air Act requirements
as they apply to continuous onboard diagnostics and
control, officials said.
In addition, the chip is designed to improve fuel economy, resulting
in financial savings for car owners. Ford engineers do not
predict a price increase for installation of the chip because JPL designed
a computationally powerful neuroprocessor that could
be mass-produced in a highly cost-effective way. The technology also
improves customer satisfaction by virtually eliminating
distracting false alarms about misfiring that vehicle dashboards can
signal with current under-the-hood diagnostic technology.
JPL and Ford scientists say the chip represents the first significant
change in the way computing is done on vehicles since
computers were first introduced into automobiles in the 1970s.
"Neural networks are a new discipline, and diagnostics, prognostics
and control is a huge field. Ford's application is but the tip
of the iceberg of this chip's potential use in American industry as
a whole," said Tom Hamilton, program manager at JPL's
Dual-Use Technology Office, one of JPL's many technology transfer arms.
"JPL is proud to be able to make this revolutionary
technology available for U.S. business."
The licensing agreement comes on the heels of a less formal Technology
Cooperation Agreement that had existed between JPL
and Ford since 1993. Under terms of that agreement, JPL and Ford engineers
worked cooperatively to refine applications of
the emerging technology to Ford's specific needs.
The new license provides Ford with rights to intellectual property of
the chip for auto industry applications, while JPL, which
has applied for patents to the technology, retains general rights.
JPL is managed by the California Institute of Technology, which
serves as the party of record for this license.
Neural systems were inspired by the architecture of nervous systems
of animals, which use neurons, a form of parallel
processing elements, to process large volumes of information simultaneously.
In vehicle applications, artificial neural networks
will "learn" both how to diagnose problems like engine misfires and
control the engine to optimize fuel economy and emissions.
"What JPL has brought to the table is expertise in designing and building
what are known as neural network 'application-
specific integrated circuits'," said Dr. Raoul Tawel, who led the development
at JPL for the chip. "With Ford, we are
implementing highly complex neural network software code in dedicated
hardware logic. This brings about a tremendous boost
in computational ability compared to traditional software-based approaches,
enabling real-time onboard diagnostics for the first
time."
For misfire diagnostics, it is necessary to observe and diagnose every
engine firing event, estimated at over one billion in the life
of each car.
In addition, the diagnostic error rate has to be extremely small, less
than one in a million, in order to avoid sending false alarm
signals to the driver. The new chip will accomplish that task by "learning"
diagnostic tasks during the vehicle development
process, bypassing the need to develop conventional software that,
in any event, can neither perform these tasks as well nor be
implemented in large production volumes with standard microprocessors.
The neural network chip, designed to carry out
parallel neuron computations efficiently, overcomes the computational
barriers that prevent this technology from being exploited
today.
A detailed, technical explanation of the technology written by Tawel
and Drs. Ken Marko and Lee Feldkamp of Ford's neural
network team, among several others, is available on the Web. "Custom
