A very good invention, now you can program magnets to get a complex field of your choice.
There is also a video on that page.
Another great find, Omega :)
That is very interesting... That having these opposing pole "sections" within the same metal piece, will create a force that is 150% that of conventional attractions when mated-up with a piece that is oppositely programmed.
I wonder, if instead of having specially programed regions within a single structure, that small cylinder-shaped Neo's could be clustered together to create the same effect.....
This could be useful: Stronger face-to-face "pull".... Yet weaker shearing strength "side-to-side".
Yes, this could be very useful for OU research.
It is indeed like placing many micro-magnets together to design your own field. You will get unexpected results.
it would be interesting to find out if nitinol memory metal can be alloyed with high magnetic materials to produce a Magnetic Memory metal that changes shapes according to magnetic field interactions.

I believe so. It appears it is nothing more than halbach arrays with certain complimentary or anti-complimentary patterns that will lock and unlock according to the pattern or code. Take a look at Figure 3 & 4 of the Correlation Theory on CMR website and you will see how the patterns work together and is nothing more than two halbach arrays that are mirrored to each other, http://www.crr-llc.com/cmr/corrtheo.html . Compare figure 3 & 4 to some of the configurations of the halbach arrays on wiki and you will notice it is the same technique, http://en.wikipedia.org/wiki/Halbach_array . Here's the page on the coding theory of "barker codes", http://www.crr-llc.com/cmr/codetheory.html . Barker codes are used in communication devices. Wiki link for the barker codes, http://en.wikipedia.org/wiki/Barker_code
Take the halbach array or an array of electromagnets, then add patterns of different polarities to each individual array that are mirrored to each other that works as a key and you have a patent (LOL).
I believe the barker codes would be used in an array of electromagnets to generate a pattern or code in real time according to the desired application. This can be used in real time with electromagnets or can be used to program the permanent magnets when they are manufactured.
The permanent magnets are not programmable in real time and are programmed at the time of manufacturing. They can be custom made according to the desired application. Halbach arrays with these same patterns and codes can already do the same thing. Instead of building the halbach arrays after the magnets are manufactured, they are creating halbach arrays with different polarity patterns at the time of manufacturing.
This is nothing new. It's a play on words. It's a sneaky way to get a patent on something. I believe this same method has been used to file more than 65 patents, http://www.crr-llc.com/cmr/Patents.html
i would have to disagree on it being close to a Halbach, and the negative characterizations of the Patent and technology.
Lol it rather sounds like Arthur C. Clarke's Third and Fourth Stages of a tech being accepted: "Its not significant", and "I thought of it first". I guess the Inventor can take solace that the First and Second phases are over, hehehe ;)
A Halbach is "arrayed" in four directions ("up", "down", "right", "left"). This appears to be a "binary" system; either "N" or "S" facing out. If you 3-D mapped the interactions of the Gauss fields (ala Dr. Gerhard Beyer's system from the Virginia Tech Study done with Steve Davis and Howard Johnson in the late 1980's.. or some similar technique), they would appear significantly different...Centainly different enough to legitimately warrant a Patent.
But the comparison does bring up some interesting questions on the possibility of using the system for magnetic bearings ;) I suspect the gaps and tolerances between the two "races" would need to be much smalled & tighter than with a Halbach; because of this greatly weaker field at longer distances.

The halbach is arrayed either "N" or "S" according to how you want your magnetic field to be. The "N" and "S" makes up the binary system in a Halbach Array. The reason why it is arrayed in four directions is to cancel the field on one side while increasing the strength of the field on the other side. The Halbach array is about canceling the field where you don't want it and increasing the strength of the field where you want it by arranging them in specific orders. You could also array it to create patterns and codes that are mirrored where they work together just like in this patent.
The barker codes are also a "binary" system; either "+1" or "-1". The barker codes are used in the coding of the magnets. +1 would be North and -1 would be South, or vice versa and this will be how they generate their patterns or codes with complimentary or anti-complimentary patterns according to where you want the fields to be canceled and strengthened just like the Halbach Arrays.
The bottom line is we can create a Halbach Array with patterns that will do the same thing as this patent. You asked if it could be done, and I am suggesting to you how it is being done and how to do it.
There is nothing mysterious about this invention and it is very misleading on how it's being promoted, thus the negative characterizations of the patent. The terms programming and coding the magnets are extremely misleading and down right deceitful. Companies use deceit to get the general public overly excited about their products or services, to raise money from investors and shareholders to line their pockets. This is how the game is played in the world of business.
The question is will the patterns or codes allow us to do something amazing or new. If so, then I will have a positive reaction to this "improved concept" of an old technology. I will give credit to where credit is due. I will say it is a brilliant idea to use the patterns, but the patterns are being formed according to an old idea, which is the Halbach Array.
Hopefully this patent will inspire others to learn how the Halbach Arrays can strengthen and cancel the magnetic fields where you want it or don't want it and how they may interact with each other with different patterns or codes which may be the key to unlock OU. I think the potential is there, but as always it will be dismissed in favor of a wild goose chase trying to replicate fraudulent things in which nobody knows how they work.

These magnets would allow one to at least control
the gradient through a series of magnets rather
than have to try to sort magnets by field
strength.

Here is Larry Fullerton's first prototype on the conception of correlated magnets in figure 3, http://www.crr-llc.com/cmr/Intro.html . He used nuts and bolts to secure round magnets to two substrates.
Here's a video on a simple circular halbach array on youtube, http://www.youtube.com/watch?v=qv-9IAj_YnI&feature=PlayList&p=87C7255CC71FD066&index=19 .
Please note in the video, how each magnet is held in position with screws, and how he mentions the last four magnets were very difficult to get into position. This is the very reason why Larry Fullerton had to bolt is magnets down also in his prototype.
The prototype on their own website proves that it can be done with an array of magnets like I suggested. It's the same way the Halbach Arrays are created. The company even mentions on their own website that the correlated magnetic structures are an "array" of magnets.
It is nothing more than putting a spin on two individual Halbach Arrays which are related by a correlation or pattern, thus "correlated magnets". This spin on things is a really brilliant idea though! IMO, there is a huge potential in this.

The paranoia displayed by gravityblock is pretty extreme. There is nothing at all "sneaky" or "deceitful" about this. It's fun to say that you could have thought of it first, but the fact is that you didn't. This is not some big pharmaceutical company that is trying to use patents to keep people from being able to get generic medications. I would watch the potential libel here. Saying things like that about a small startup can be damaging to people who don't at all deserve to have their reputations damaged. I've seen people sued over less viscousness than this.

I'm paranoid about someone re-inventing the wheel? LOL. This being your first post and the way your defending this company, it wouldn't surprise me if your not a representative of this company and threatening me with a libel suit.
This is nothing new. It's an array of magnets just like halbach arrays, and they even say so in their own website that it is an array of magnets. The only difference is two sets of arrays are used together.
I could care less who invents something first. I can't be libel for saying something that is true. So, basically you saying anyone who does a review or publishes an article that is negative to a company or it's products can be sued, LOL. That is being extremely paranoid in my opinion.
"Being able to program the magnets" along with other similar statements is deceitful. Let them bring a law suit, and I will file a counter suit for deceitful and fraudulent claims and I am sure the investors will back me and follow suit once they realize it's a scam. This is a business. Businesses always put a spin on something even on the smallest of things. It's about money and investors.
Do you know that you can now be sued on patent infringement for using magnets in certain configurations, even very simple configurations? This includes 2 sets of magnets placed parallel to each other where each side has an opposite pole than the other side. This would be patent infringement. It's not paranoia, it's fact.
We're a society of people who sue. What a way to be. Nobody can have a negative opinion anymore. LOL
Below is my failed attempt at drawing a simple configuration of magnets in 3D that is patent infringement against this company. Basically, any combination where both sets would align with each other in different configurations or patterns is now patent infringement.
Thank you so very much for standing up and fighting for your own rights. The way things are going, the working people will have nothing to hold on to. Not even an arrangement of magnets, LOL. As you can see in the illustration, they should get the Nobel Prize for their "Great Physics Discovery". I think not. If your a representative of this company, then go file your suit!
Two days after registering, PLA has yet to make a comment on any other thread. It really appears he just registered to defend this company and to make threats. If this is the case, then it really shows what their true business model is, making threats and filing suits.
In fact, I've had many forum members ask for my e-mail address over the last few weeks out of the blue. Any member will be given a false e-mail address.
I'm really tired of corporations trying to rule and suppress the people with their money. They just want more money, it's never enough. Microsoft would have millions of people in court for negative comments about their company and products.
Cedar Ridge Research (CRR) is into fast tracking and protecting intellectual property rights. They don't care nothing about the truth, they only care about their financial bottom line.
This paranoia is unbelievably silly. I just live in the same city and have been reading various blogs and news stories about the company and the magnets to learn more. I have no threats to make, I was just mentioning that I have seen a lot of libel suits lately because of this kind of thing. I've seen two just in the past four months from local companies.
It's kind of shocking to see that people are this upset about really nothing at all. So because I disagree, I'm a corporation? Seriously? I have an opinion, and it's perfectly valid.
You know absolutely nothing about the company at all, and comparing it to Microsoft is beyond laughable. This level of paranoia is unhealthy and ignorant. But, I guess that's to be expected from people who say things like "they don't care nothing." Pick up a book once in a while. Education is the only way to elevate you from your current status of pig lurking around message boards and spouting nonsense to make yourself feel important.

@PLA:
I never said I didn't care about nothing, (I said I didn't care who's idea this was first). I never said I thought of this idea first, (It was known prior to the inception of this company or their research). Lawsuits is the American way of doing things, from what I read and see on the news in my country. This is not a breakthrough in physics like they claim on their website. This affect with magnets was discovered by Mallison in 1973.
In the 1980s, the late Klaus Halbach, a physicist at Lawrence Livermore National Laboratory, invented the Halbach array to focus accelerator particle beams."
The humble refrigerator magnet, brushless motors, magnetic coupling, magnetic bearings is all based on this affect of magnetic arrays. The arrays are also a key component of the Inductrack maglev system, wiggler magnets used in particle accelerators and free electron lasers.
Although I feel like their marketing and advertising of their magnetic array structures are misleading, they do have an excellent product. They should have a huge market, since the array's could be customized and mass produced at lower costs.
I am sure they are or was unaware of the halbach arrays at the time of their research and discovery. I could only imagine the excitement of their experiments which led them to the structured magnetic arrays. Many times I have re-discovered on my own what others before me had already discovered. It happens to everyone and this company is not exempt from this happening to them either.
In my opinion, their structured magnetic arrays and the halbach arrays are the same technology.
I may not know a lot about the company, but I do know about the technology because I have done a lot of research on halbach arrays prior to even hearing about the company.
I wish them the best, but some of their marketing claims are outrageous and misleading in my opinion. The majority of companies have similar marketing and advertising claims that are misleading to the end consumers or investors. Most companies pay copyrightors alot of money to make their products or services appear to be more amazing than they really are in reality. That is the nature of business. Please, don't take any offense to my opinion. I will respect yours.
Take care,
GB
I appreciate the comment. I was starting to think that this forum was a hostile environment. When it comes to any innovation, people will have very differing opinions about its use, its value and just how innovative it is.
Hi folks ;D I was just doing a dangerous thing (thinking again!) these programmable magnets unless im totally misunderstood of the concept could mean there would be a possible way to get the magentic field array for the floyd sweet vta - that needed 'conditioned' magnets with coils wound on all three axis' and pulsed currents etc so it created this specific mag field....any thoughts anyone?
eel :D
