INDUSTRY AND THE
FUSE BURNS OUT
In June of 1999, the Far Ultraviolet Spectroscopic Explorer
(FUSE) was launched from Cape Canaveral atop a
Delta-II rocket. It was a Johns Hopkins-managed NASA
mission that complemented the Hubble Space Telescope
by making observations in the short UV range below
Hubble’s capabilities. In its illustrious career, its original
three-year mission was extended by NASA three times and
made discoveries about everything from planets and nearby stars to galaxies and quasars billions of light-years away.
Alas, the satellite’s control room went dark on October
18, leaving the 18-ft tall, 3,000-lb satellite to orbit the Earth
incommunicado, awaiting its fiery demise when it enters the
atmosphere in 30 years or so. Astronomers from around the
world have published more than 1,200 papers based on
data from the satellite, which generated spectrographs rather
than photographs of distant objects. By analyzing FUSE data,
astronomers were able to measure temperatures, densities,
and chemical compositions of such objects, helping to place
them in context in the history of the universe. For a more

■ The FUSE vehicle,
launched in 1999, has
reached journey’s end.
In September, the
Institute of Electrical and
Electronic Engineers (IEEE,
launched IEEE.tv, an
that features programming
on technology and
engineering. The shows,
which are produced by
IEEE members, feature “a
variety of programming
options including hot topics in technology, conference
highlights, and interviews with industry experts.” A limited
beta site appeared about a year ago, but the new version
includes Flash video, a list of most viewed and recently
added videos, and various options for RSS feeds. As usual,
some of the juicy programs are available to members only,
but there are quite a few free, public access vids, as well.
You can check it out, appropriately enough, at
age, the devices are designed for use
in home, auto, and professional audio
amplifiers. They feature a built-in
thermal compensation diode on the
same die, which eliminates any delay
for thermal compensation operation,
as well as any delay between thermal
sensing and response. The STD01
devices handle up to 100W, and
the STD02s can go to 130W.
Both are available in PNP and NPN
versions, and they offer an
operating range of - 55 to

If you need to make
quick noncontact temperature measurements,
the model OSXL450 noncontact IR thermometer
from Omega Engineering
be of interest. It uses
a patented circle/dot
sighting system and
offers a 6:1 field of
view. The instrument measures temperatures from - 20 to +320°C
(- 4 to +608°F) in less than a second. It
also features a backlit display for night
use and an auto shutoff.
The OSXL450 is CE compliant
and is designed for a wide range of
applications including manufacturing,
automotive, and mining industries.
The $59 price tag even includes
batteries and a wrist strap. Such a
