As in science, the world of technology has grown in
leaps and bounds. Man's desire to control the world around him has
driven technology to a frenzied level. Pentium 4 computer chips whizz
along at amazing speeds. Doctors can operate remotely from the other
side of the Earth. And of course there is the race to see what really
is out there beyond Earth. One has to wonder if man can keep up with
his own pace. And if all that he is creating is really beneficial to
his fellow man. Here are a few items of interest in the world of
technology.
Researchers at Stanford University have developed a
cutting-edge device that may help you realize your wildest dreams
while you sleep comfortably in bed. Stephen LaBerge has spent years
studying lucid dreaming, defined as the experience of dreaming while
knowing that you are dreaming. He founded the Lucidity Institute at
Stanford, where research subjects are taught to understand their
dreams as a state of consciousness where anything is possible, and all
is within their power. "What makes a good lucid dreamer is
someone who has inner awareness," says LaBerge. "You've got
to sleep with the intention of having a lucid dream." In order to
assist dreamers have more lucid dreams, LaBerge engineered the
NovaDreamer, a high-tech mask with sensors that detect Rapid Eye
Movement while you sleep. Lights embedded in the mask flash on and off
to encourage a heightened sense of awareness while remaining in REM
sleep. After a while, the mind becomes trained to understand the
visual cues as a subconscious alarm clock that awakens the mind to a
lucid dreaming state. Once in a lucid dream state, users can better
understand and manipulate the context, or dream "reality"
that surrounds them. The result is a richer dream experience. He sees
exciting future applications in therapeutic treatment of nightmares,
self-confidence, mental health, experimental learning, and also for a
general exploration of our consciousness. "After all," says
LaBerge, "dreaming is a powerful manifestation of our
consciousness." (ABC News).
"Robodog," developed by RoboScience, is
the Labrador to Aibo's Chihuahua, some might say. Robodog can walk,
climb and even read e-mails through its synthesized activated voice.
Through camera lenses and microphones hooked up to the Internet, the
dog can even "hear" and "see," allowing it to act
as a guard dog by letting its owner know if it sees movement.
"It's a PC on legs," says designer Nick Wirth, who formerly
designed Formula One race cars. Wirth refers to the Microsoft Windows
program that acts as a brain to power the Robodog. Strong enough to
lift a 5-year-old child, Robodog looks fierce but is amazingly light.
Influenced by Formula One engineering, designers used carbon fiber to
construct the dog. Being lightweight is considered crucial for future
developments of human life-size robots, which if too heavy could pose
a danger to its human owners. Only 200 dogs are being built because of
a $30,000 price tag. However, RoboScience sees its dog as an
investment into the future dog-eat-dog world of robotics. (ABC News).
Diabetics won their first painless way to measure
blood sugar, as the government approved a wristwatch-like device to do
the job. Cygnus Inc.'s GlucoWatch checks glucose levels every 20
minutes by sending tiny electric currents through the skin. The
GlucoWatch won't completely replace those finger-prick blood tests
that diabetics perform because it's not perfect, sometimes giving
erroneous readings, the Food and Drug Administration warned. But it
will supplement finger testing, providing the more frequent blood
monitoring that can help keep diabetics healthier, the FDA said.
Better, it sounds an alarm if blood sugar hits dangerous levels —
possibly life-saving if glucose plummets while they sleep. (Associated
Press).
The Ford-GM Crash Avoidance Metrics Partnership —
in cooperation with the National Highway Traffic Safety Administration
and Electronics Systems — has developed a preliminary version of a
forward collision warning system. Researchers hope the device will
make a big dent in rear-end collisions, which NHTSA says about 23 per
cent of all police-reported crashes in the United States. The alarm
involves radar that measures the distance, relative speed and angle
between cars. Researchers determined that bringing a car to a normal
stop involves a very specific amount of force. "Once you need
more braking than that to avoid hitting something, we decided to give
a warning, so there's still time to brake hard and avoid the
accident," said Dr. Michael Shulman, a technical specialist at
Ford Research Laboratory. Much of the research has been devoted to
calibrating the system. The timing of a near-collision can be tricky,
and scientists are still experimenting to find the system's sweet
spot. If the alarm sounds too late, it won't prevent a crash. However,
if klaxons blare every time the car nears a bumper while parking, the
result will be annoyed drivers and disconnected systems. In a
controlled environment, the crash alarm has performed well. At the
University of Michigan Transportation Research Institute, 104 of 108
drivers in a braking test stopped the car in time to avoid a crash.
