Correlated magnetics is a fundamental breakthrough in magnetics. By combining many magnetic fields, CMR’s patented Polymagnet® technology transforms ordinary magnets into precision-tailored magnetic systems that produce complex functions not possible with conventional magnets. Magnetic functions are created with the world’s first magnetic printer, the CMR MagPrinter®. The MagPrinter creates patterns of small magnetic regions called maxels on rare-earth, ferrite or flexible magnetic materials. Each Polymagnet pattern creates a unique function – demonstrated in videos below.
We've been doing something like this for many years, and most of you probably already have such a device, called a hard disk drive, which has correlated magnetic patterns in a spatial domain.
Working on a toy for his grandson, scientist and inventor Larry Fullerton wondered whether coding and correlation theory used for communications in radar signals in the time domain could be applied to magnetic structures in the spatial domain.
The hard drive platter has a spatial magnetic pattern on it. We don't push another platter against the platter in hard drives which would be more analogous to what's shown in the video. Instead, we float a small probe over the platter to read the magnetic encoding, and it gives us useful data storage.
I think you're missing the point. The toy is only what got him started.
So you're saying this in nothing new.
This is very sophisticated engineering.
One of the most sophisticated engineering aspects of the telescope is what is known as "adaptive optics." The telescope's secondary mirrors are actually flexible. Under each secondary mirror surface, there are hundreds of actuators that will constantly adjust the mirrors to counteract atmospheric turbulence. These actuators, controlled by advanced computers, will transform twinkling stars into clear steady points of light. It is in this way that the GMT will offer images that are 10 times sharper than the Hubble Space Telescope.
What is shown in the OP video is frankly not very sophisticated. But maybe it will prove useful somehow.
