Patient eases
others' pain
with invention
By Craig Lancaster
The Shorthorn
U. of Texas, Arlington
In February 1971, Steve Schuchman
was diagnosed as having Hodgkin's Dis-
ease, or cancer of the lymph system.
He was 19.
After a series of full-body radiation
treatments, the disease was eliminated,
only to return in 1979. Once again,
Schuchman had to undergo che-
As he lay in a hospital battling cancer
for the second time, an idea struck him
- an idea that won him third place
among 1,515 entries nationwide in the
Motorola University Design Contest
this past June.
His winning entry: a device that com-
puter-monitors the flow of intravenous
(IV) injections. The apparatus utilizes a
Motorola microcomputer chip, a re-
quisite of the contest.
"If I ever go back to the hospital,"
Schuchman said, "I'm taking this thing
with me. I'll experiment on myself.
"During chemotherapy, in particular,

the immune system is depressed," said
Schuchman, now a computer science
and engineering assistant instructor at
U. of Texas, Arlington. "The chemother-
apy drugs damage the veins. A typical
IV doesn't last long - the flow stops.
"Soon, blood clots form in the needle.
All the medical assistants can do is pull
out the needle and reinsert it some-
where else. I would be stuck with a nee-
dle four or five times a day."
The device, which can be produced for
less than $200, allows flow rate to be
programmed both directly into the unit
and from a remote computer terminal.
An alarm sounds when IV flow stops
or is rtot within prescribed limits.

It can walk, climb, dig and drill. With
programming, it can turn cartwheels.
On its side is a university logo.
Its name is Skitter, a three-legged
robot invented by Dr. Jim Brazell, a
mechanical engineering instructor, and
graduate students Brice MacLaren and
Gary McMurray. Several undergradu-
ates also helped out.
The robot is part of the NASA/Uni-
versity Advanced Space Program.
NASA gives contracts to schools in the
University Space Research Association
to design studies for equipment to be
used when man establishes a perma-
nent colony on the moon.
A prototype of the robot was designed,
built and tested for $4,000 and pre-
sented to NASA in Washington, D.C.
"We blew all the other universities
(that did presentations) away because
they really never got beyond the draw-
ing board," MacLaren said.
Skitter went beyond that, winning
the Design News 1988 grand prize for
excellence in design.
"We blew all the other

presentations) away

got beyond the drawing
Since Skitter is a walking vehicle, it
can be very light with effective traction,
making use of gravity to bring itself
down once it raises a leg. It uses forward
momentum to help propel itself, some-
what resembling a person on crutches.
It can pick up cargo, tilt to aim a drill
bit, serve as a crane platform and dig
soil without using other equipment.
While traditional walking vehicles use
four to six legs, Skitter is a tripod and
can easily step around obstacles.
The team is adding locking wheels to
Skitter's legs, enabling it to negotiate
hilly terrain.

'chips' away
at space future
By Brian Holloway
The Argonaut
U. of Idaho
Scientists and engineers at the
U. of Idaho's (UI) Microelectro-
nics Research Center (MRC) have
developed a series of computer
chips, capable of processing 1.6
billion operations per second, that
will be used in NASA space satel-
The chips will be used by the
National Aeronautics and Space
Administration to correct errors
in data returning to Earth.
The chips are the first of their
type, according to Don Wiseman,
an electrical engineering student
who helped with the project.
"These are specialized chips,"
Wiseman said. "This is the first
set of chips to be designed for
error corrections." He said the de-
sign is what allows the chips to

Double Take
Is it real? Or is it a clever fake
by photographer Schapiro?
By Scott Lipsett
Daily Trojan
U. of Southern California
In Hollywood, there was Lon Chaney, the man
of a thousand faces. At the U. of Southern Califor-
nia (USC), there is Martin Schapiro, the man of, so
far, six faces. But Schapiro doesn't do monsters.
He does rock stars - big ones.
Schapiro and his students recreate photo-
graphic images found on album covers. "I had al-
ways wanted to be Bruce Springsteen," Schapiro
said. "I had a poster of the Born To Run album and
I wondered if I could redo it."
Schapiro has played a range of characters, from a
drunk in Sheila E.'s The Glamorous Life, to Billy
Joel's The Stranger, John Cougar Mellencamp's
Scarecrow, Bono in U2's The Joshua Tree, and most
recently, Sting in Nothing Like The Sun.
"As long as there are rock and rollers that I can play,
it'll go on," Schapiro said. "When I have to start doing
Perry Como or Frank Sinatra, maybe I'll stop."
Schapiro came to the USC School of Cinema-Televisio:
in 1984 to begin a photography department emphasizin
professional techniques. "I don't think I'm really here t
just teach photography, I'm here to teach experience," h

engineering into realms that have been,
until now, unimaginable," said UCB en-
gineering Professor Richard S. Muller,
who invented and successfully' tested
the tiny motor in July along with two
UCB electrical engineering graduate
students, Long-Sheng Fan and Yu-
Chong Tai.
Muller said the development of mic-
roscopic cranks, gears and springs in-
spired the trio to assemble what is be-
lieved to be the world's smallest motor.
Muller's rotating motor, designed
with notched teeth the size of red blood
cells, will open the door to developments
in more intricate microsurgery tools,
scientific measuring devices and a more
compact line of consumer electronics,
according to a report released in May by
a National Science Foundation (NSF)
workshop on micromachinery.
Other possible practical medical de-
vices cited in the NSF report include a

tiny buzzsaw for slicing away scar tis-
sue from retinas and "smart pills" which
would dispense exact doses of medica-
tion through microscopic valves when
swallowed. Physicians could also inject
micromachines into arteries to scrape
away fatty deposits and prevent heart
Not only is the product itself unique,
but the manner in which it was created
is a breakthrough in technology:
The finished product is three
thousandths of an inch across and one
ten-thousandth of an inch thick.
It is made of polycrystaline silicon,
the same material used to manufacture
computer chips.
The micromotor was assembled
under similar conditions as computer
chips, making mass production of mini-
ature machinery a distinct possibility.
The polysilicon is sandwiched be-
tween layers of a temporary silicon
dioxide framework, which dissolves
once the motor is assembled.

Melbin said. Since we've run out of land,

According to Melbin's estimates,
based on 1980 census data, there
were at least 3 million people working
in 1980 during the quietest hours,
from 3 a.m. to 5 a.m. At 1 a.m., more
than 4.5 million nationwide were still
at work. He added that since the eco-

of his three-late-shift week. "The
whole world is at your command."
However, Jan Schluter, patient-care
coordinator at the Sleep Disorder Cen-
ter at Hennepin Medical Center, and
many experts claim that overnight
work can be unhealthy. It can mix up
the worker's circadian rhythms (better
known as the body's 24-hour biological
clock that adjusts to the way one
sleeps), they say, damaging sleep pat-
terns and causing extreme fatigue and
other ailments.
Upsetting this rhythm can result in
gastrointestinal problems and sleep de-

privation, Schluter said. She acknow-
ledges, however, that younger people
can adjust their rhythms more easily
than older people.
Leazer cited sleep deprivation as the
biggest drawback to working nights.
"Mentally, you can't do anything, espe-
cially between 3 and 5 a.m," she said.
There are students around campus,
however, who are wide-eyed during the
wee hours of the morning, yet not hard
at work. Some are just night people who
love the quiet, relaxed atmosphere that
the night provides.
