Posted July 19, 2018 11:21:23A new type of digital instrument called a reed-solomon encoder uses a small magnet to make a sound.
If the magnet doesn’t work, the sound is just a digital noise.
But the reed is so thin that when you pull the magnet out, the noise is picked up by the detector.
This is a very sensitive instrument, and its use in space has been limited because it’s not practical for satellites, because it can’t sense Earth’s gravitational field.
Now, the University of Washington and NASA have developed a new design that can detect reeds at hundreds of feet per second.
“We’ve been working on this for several years,” said David Shur, an associate professor of electrical engineering at UW who co-authored the paper.
“I’ve been developing this technology for a number of years.
I’ve been very excited by the fact that we can actually make it work, and it’s very exciting.”
Shur is one of the people working on the project with the University.
Other researchers in the field include Joshua Lee, a graduate student in electrical engineering and the lead author of the paper, and David Tovar, a UW postdoc.
“It’s a very novel instrument,” Tovars said.
“You can actually tune it to detect reed vibrations.”
The instrument is a special kind of magnet that is about 10 times thinner than the human hair.
When it detects the sound, the signal is picked off by a special antenna on the instrument, called an altimetry array, and then amplified.
The amplification is then sent back to the detector and recorded by a digital camera.
“There’s a lot of noise and you can’t detect the source because you have to make the signal very small,” Travar said.
The new design uses an extremely thin material called tungsten carbide, or tc, which has a relatively low resistance.
When tungstron is heated, it forms a special layer in the center of the magnet that acts as a resonator.
When a small amount of heat is applied to the tungs, they form a tiny acoustic cavity, where the magnetic field can be detected.
The noise is made by the sound wave that travels from the tengsten carbides surface to the antenna, where it is amplified by the amplifier.
The sound is detected by a microphone and then translated to a digital signal, which is amplified and recorded.
Shur said the instrument could be useful for satellites that rely on the Earth’s gravity to keep them in the right position.
“When the space station is on the way, the Earth gravity forces the space shuttle to be in the correct position and the space ship has to be aligned,” he said.
When the space craft is not in a specific position, it will be pulled back toward Earth by the force of gravity.
“If you have a space shuttle that’s in the wrong position, the space vessel is going to be pushed back, and the shuttle will have to be re-aligned,” Shur explained.
If you are using the space vehicle in a way that is different than what the space agency is looking for, the spacecraft will have problems.
“So you have that kind of scenario where you can have this space vehicle go in a different direction, but you still want to keep the space center in the same spot.
And then you have this other scenario where it will have a problem with the space space station,” he explained.
“In that situation, it’s hard to fix the problem, and you have these problems that come out of it.”
The design also has some downsides.
“The antenna, because of the tc layer, it has a low bandwidth.
The more the tcr layer is heated up, the lower the bandwidth of the signal,” Tavars said, and “it’s going to have a very short lifetime, so it doesn’t last very long.”
A laser beam is used to light the tchronal carbide layer.
The laser beam creates an electromagnetic field in the tsc layer that acts like a resonant microphone.
“Once you start heating the tcs up, you get these resonant micrometer waves,” Tivar said, which are amplified and amplified to create a very narrow signal that can be picked up with the instrument.
The researchers are currently developing a new antenna that could be used for use in the space industry.
They plan to take their design and test it in space for at least one year.
Shor said that his team is working on other designs for space applications that could use the instrument to measure Earth’s magnetic field.
“But for now, we’re just working on our own, because there’s no one else out there that’s making these kinds of instruments,” he added.
“For now, the instrument is very, very promising.”
