Realizing the Future of Automation
They may not
be taking over the worldat least not yetbut robots are
getting smarter. And a growing number owe their brainpower
to NIST.
In 1991, a floor-cleaning
robot became the first commercial intelligent machine
influenced by NISTs real-time control system (RCS), a concept
for controlling automation developed by NISTs Jim Albus, a
leading robotics researcher. The RCS has a unique hierarchical structure
that creates an efficient organization for knowledge-based intelligent
control of complex systems. Other commercial machines based on this
concept are improving the precision of shipbuilding, delivering
hospital supplies efficiently, and keeping U.S. troops out of harms
way by clearing land mines in Bosnia.
The RCS was
among the influential technologies to emerge from NISTs Automated
Manufacturing Research Facility, created in 1982 to provide a national
testbed for R&D in computer-integrated manufacturing. The facility,
which was co-sponsored by the U.S. Navy and involved research collaborations
with industry and universities, has led to dozens of commercial
products and many national and international standards.
Among the contributions
is the Standard for the Exchange of Product Model Data (STEP), which
is designed to overcome interoperability problems that arise when
automated systems attempt to share product and engineering data.
These problems cost the auto industry alone about $1 billion annually.
First released in 1994, STEP is a universal file format that supports
computer-to-computer exchanges of all types of product data. Significant
cost and process improvements have been
reported by users.

Neutrons Offer New Insights
From checking
on food safety to nailing crime suspects to probing biological membranes,
the NIST Center for Neutron Research (NCNR) has done practically
everything a scientific facility can doincluding some things
that would be impossible anywhere else.
The center
offers a broad array of instruments and capabilities, some of which
are unique in the United States and even the world. A special set
of rare tools was added in 1991, when the Cold Neutron Research
Facility was completed and became the first U.S. facility devoted
solely to research with cold (lower-energy) neutrons.
Neutron beams
interact with the inner structures and dynamics of virtually any
material, often revealing details that cannot be discerned in any
other way. In its early years in the 1970s, the NCNR perhaps was
best known for the use of warm neutrons in forensic
investigations, such as the time when postal authorities matched
specks of paint from a burglars tool satchel with the paint
at several post offices and broke up a burglary ring.
Today, the
center is pushing the frontiers of many fields of science. For example,
research with cold neutrons has revealed molecular mechanisms
involved in regulating muscle contraction and led to the development
of improved additives that enable diesel fuel to remain fluid at
subzero temperatures. Depth-profiling techniques led to the creation
of a titanium nitride Standard Reference Material that now is used
in semiconductor testing, meeting one of that industrys greatest
needs. Magnetic measurements have helped to explain the origin of
the behavior of materials exhibiting giant magnetoresistance,
the basis for ultrahigh-density computer hard drives..

1995
Creating a New State of Matter
Pushing the
limits of technology is NISTs forte. It paid off in a big
way in 1995, when scientists at JILA, a joint program of NIST and
the University of Colorado (CU), created an entirely new state of
matter predicted decades ago by Albert Einstein and Indian physicist
Satyendra Nath Bose.
The Bose-Einstein
condensatewidely hailed as one of the centurys major
achievements in physicsis an atomic counterpart to the laser
in that a large number of atoms are in the same quantum mechanical
state. (Lasers cause a large number of photons to have identical
energy and direction.)
To make this
new state of matter, NISTs Eric Cornell (pictured on right)
and CUs Carl Wieman cooled rubidium atoms to less than 1 millionth
of a degree above absolute zero (the hypothetical point at which
a substance would have minimal energy), as much as 300 times lower
than ever achieved in other scientific laboratories. At a certain
temperature, the atoms condensed into a superatom that
behaved as a single entity.
The achievement
was made possible by laser cooling and magnetic traps, technologies
that NIST played a major role in developing. Infrared lasers, similar
to those used in compact disk players, were aligned so that the
atoms were bombarded by a steady stream of photons from different
directions. Once the atoms were slowed and cooled, they were kept
in place by a magnetic field and further cooled until the condensate
formed.

Biotechnology for the 21st Century
A device the
size of a keychain launched an industry-and giant strides in science
and medicine-in 1996, when it became the first commercial "DNA chip."
It did so with
the help of NIST's Advanced Technology Program (ATP), which accelerates
the development of innovative technologies for broad national benefit
through R&D partnerships with the private sector.
The DNA chip
is so named because of its similarity to the tiny integrated circuit
that fuels the electronics industry. The difference is in the application.
The newfangled device enables the operation of a miniaturized biological
laboratory that quickly analyzes the genetic makeup of blood or
tissue samples.
ATP funding
also has led to other next-generation products for DNA analysis
that have appeared on the market or in research laboratories, greatly
advancing capabilities for research on human genetics, discovery
of new drugs, improvements in agriculture, and testing of food and
cosmetics. The new technologies are already up to 1,000 times faster
than conventional methods, thereby saving time and money. They also
are highly accurate and convenient.
As noted in
a recent journal article, the "godfather" of the burgeoning field
of DNA diagnostics is the ATP, which helped companies advance their
early research to a stage where commercialization (with other funding)
would be feasible. The ATP has co-funded more than two dozen projects
in DNA diagnostics, including one that led to the first DNA chip,
and a number of the award recipients are leaders in the field today.

Helping Small Manufacturers Thrive
Small manufacturing
firms gained an important advantage in the 1990s in the form of
NIST's Manufacturing Extension Partnership (MEP), which, according
to an independent study, boosts the competitiveness of its clients
beyond the average for companies of this size.
The MEP helps
these firms with everything from financial planning to plant layout
to environmental studies. The services are offered through a network
of more than 400 not-for-profit centers that provide small and medium-sized
companies with access to more than 2,000 manufacturing and business
specialists. In 1996, the MEP reached its goal of completing a nationwide
network, enabling all of the more than 385,000 U.S. small manufacturers
in the 50 states and Puerto Rico to gain access to MEP assistance
centers.
Through 1998,
more than 84,000 firms have taken advantage of the services, which
are fostering significant improvements in manufacturing and business
performance. For example, in a 1999 follow-up study, 4,551 MEP clients
reported increased revenues of $294 million, $29 million in labor
and materials savings, and $20 million in inventory reductions,
while also investing $291 million in modernization. These clients
also reported creating and retaining more than 7,000 jobs.

Fire Research Helps Save Lives
Three decades
ago, U.S. fire losses were so large that a presidential commission
was appointed to study the problem. The commissions 1973 report
urged a greater emphasis on fire research, prevention, and education
and set a national goal of reducing fire-related losses by at least
50 percent.
A 50 percent
reduction in the U.S. fire death rate was attained in 1997. A primary
reason: Smoke detectors now are installed in more than 95 percent
of U.S. homes, compared to fewer than 10 percent in the early 1970s.
NIST researchers made this improvement possible beginning in 1974
by developing, with Underwriters Laboratories participation,
the first fire performance standard for smoke detectors and recommendations
on the number, type, and location of home smoke alarms now found
in all U.S. (and most foreign) codes and standards.
NIST also worked
closely with other government agencies, performing the technical
work underpinning the first federal standards on childrens
sleepwear and mattresses and writing the U.S. Fire Administrations
most popular educational booklets. Fire fatalities attributed to
childrens sleepwear have virtually disappeared, and those
from mattress fires have been cut in half. For the Federal Railroad
Administration, NIST also tested the fire safety of passenger train
seats (see photo on right).
The Institutes
long-standing relationships with the private sector have helped
to introduce less-flammable floor coverings into the marketplace;
verified the value of fire-retardant additives in increasing escape
time from fires; and produced the only validated method for quantifying
the lethality of smoke, now routinely used in fire hazard analysis.

Turning
Around a Key U.S. Industry
In 1991, the
U.S. printed wiring board industry was in trouble. The $7 billion
industry with its 200,000 jobs was saved, according to the president
of the National Center for Manufacturing Sciences, by a research
project co-funded by NISTs Advanced Technology Program. According
to a 1997 study, the joint venture led to dramatic efficiencies
in research and development (a $35.5 million savings, or more than
two and a half times the ATP investment), accelerated research,
and produced significant technological advances. The project also
enabled more than 30 research tasks that otherwise would not have
been attempted.

Laser Cooling and Trapping
Win Nobel Prize
Atoms or molecules
in a gas are difficult to study because they move so fast. The molecules
in air, for example, move at about 300 meters per second, or 1,000
kilometers per hour. But by pushing on the gaseous atoms with laser
light, scientists can slow the atoms down, cooling them to within
a millionth of a degree of absolute zero. NIST physicist William
D. Phillips (pictured on right) won the Nobel Prize in physics in
1997 for his work on the development of methods to cool and trap
atoms with laser light.
The discipline of cooling and trapping atoms, which emerged with
the advent of laboratory lasers, was established in part by experiments
with ions (electrically charged atoms) by David J. Wineland and
others at NISTs Boulder campus beginning in the 1970s. Inspired
by this work, Phillips and his team demonstrated both the trapping
of atoms (which are electrically neutral) with a magnetic field
and the cooling of atoms well below the temperature limits generally
believed possible.
The Nobel committee
said the new methods of investigation developed by Phillips and
two other 1997 prize winners have contributed greatly to increasing
our knowledge of the interplay between radiation and matter. In
particular, they have opened the way to a deeper understanding of
the quantum-physical behavior of gases at low temperatures.
The research
has enabled the design and construction of one of the worlds
most accurate clocks, NIST F-1, which is used by NIST (in cooperation
with the Naval Observatory) to maintain the nations time standard.
In other experiments at NIST, laser cooling and trapping have been
used to achieve a new state of matter. Some day, this research may
lead to practical advances such as quantum computers capable of
processing information in unique ways.

Flawed Rivets May Have Sunk Titanic
Since the sinking
of the giant ocean liner Titanic in 1912, numerous theories
have been advanced about the causes. NIST has one tooweak
rivets. NIST metallurgist Tim Foeckes microscopic analysis
of 48 wrought iron rivets recovered from the ships hull have
revealed that nearly 40 percent contained up to three times the
amount of slag (the glassy residue left behind after the smelting
of ore) allowed at the time. This made the rivets prone to premature
failure. Titanics collision with the iceberg may have
caused the rivet heads to break off, opening seams and allowing
water to rush in between the separated hull plates, speeding the
ships descent.

Promoting
Quality in U.S. Firms
Is the quality
of American goods and services getting better? Yes, according to
the non-profit Council on Competitive-ness. The council credits
the Malcolm Baldrige National Quality Award as a key mechanism in
strengthening U.S. competitiveness.
The Baldrige
Award was established by the U.S. Congress in 1987 to recognize
individual U.S. companies for their achievements and to provide
quality awareness and information on successful performance and
competitiveness strategies. Since then, the award, managed by NISTs
Baldrige National Quality Program (BNQP) in conjunction with the
private sector, has become the nations premier award for business
performance excellence and quality achievement. Since 1988, 37 organizations
have received a Baldrige award.
More than 1.7
million paper copies of the BNQP Criteria for Performance Excellencewhich
has been called the single most influential document in the
modern history of American businesshave been distributed,
reflecting the impact of the program. (Additional copies are available
in books, from state and local award programs, and for download
from the World Wide Web.) The criteria span company leadership,
strategic planning, customer and market focus, information and analysis,
human resource focus, process management, and business results.
Also in 1999, the program was expanded to include educational organizations
and health care providers, promising important benefits to consumers.
State and local
quality programsmost modeled after the BNQPhave increased
in number from fewer than 10 in 1991 to more than 50 in 1999. Forty-three
states currently have programs. Internationally, nearly 60 quality
programs are in operation, most modeled after the Baldrige program,
including one in Japan.
