No, if JN asserts his IP here, then he has many witnesses it is his.
Publishing here does not confer IP rights to anyone else, as long as it's clear in the first place.
Witnesses to public disclosure of an invention prior to patent application can only serve to invalidate patentability. That would be my understanding.
Patents don't work like copyright, you can't just say this is mine in public. The safe bet is simply file a provisional, the cost is nominal and you don't need a lawyer. The law seems to treat certain academic and professional formal presentations with the same 1 year clock but most IP lawyers don't recommend that and why not simply wrap your paper in the application and pay the $130 or so to the PTO?
I was just thinking that richard would steal the idea, patent it for himself, get extremely rich, buy an island in the carribean and a plane to get there and back, and die in a plane accident during a level 5 hurricane..
So, I was just thinking of him..

Once you have a patent you need patent insurance, since almost no one can afford to defend their patent.
What makes you think he doesn't own an island already, jn?

So, if my ideas were novel and patentable, and cost effective enough that every speaker manufacturer on the planet would try to steal it, I'd have to personally defend against them all? That sounds like fun.. That said, as all can see, the details are not pointing to a cheap alteration, but rather a more expensive structure suited only for high end manu's. Figure the possible total quantity given a small market, how much could one possibly make after costs of patent and insurance??
Last time I dealt with a speaker manu, it was Selenium. Their D205TI tweeters kept failing on me...I diagnosed the manufacturing defect, detailed to one of their product managers exactly how to fix the problem (with drawings), requested that my payment for helping them out be four spare replacement diaphrams (about 100 dollars total). Radio silence..no thank you, no acknowledgment, nuttin..
I hadn't thought of that.😀

These neat displays were made by KGM in England, and used by General Radio.

Looks like HP never used this approach.
HP405AR Automatic DC Digital Voltmeter (1959 - ). This was the first digital voltmeter HP made.
It had three digits of resolution and could measure from 0.001 to 999 Volts with automatic ranging.
The display was nixie tubes.

Can you find anything on that Lumitron scope, Barrie Gilbert said it was a tiny UK company that was bought out by Tek? The scope cost the .gov as much as a garage full of Jaguars.
It's hard to say what the future holds for such things... Some people aren't good engineers for anything but how to make something expensive cheaper. We haven't listened to what this sounds like yet, either. Patent insurance I think is really awesome. I don't think it's crazy expensive. If you want to talk about expensive talk about UL approval...
I feel you on the Seleniums... I tried to contact a company, even was in contact with the owner. I was explaining there were some simple fixes to their patented circuit to make it much more stable. I didn't share them to "prove" I was right. But I suspect now maybe that was their intention... I would have taken a very small payment. Instead all I got was "you're not smart enough to understand the circuit and what it's doing"... when the only thing I mentioned was their models for transistors were poopy.
Scott: Doing a 'George lite' Seems the brains behind it was Robert Sugarman working at Brookhaven National labs. Still digging. Interesting bit here on how Tek missed the boat initially. http://www.vintagetek.org/wp-content/uploads/2012/01/Tek-History-Anon-RevB-small.pdf page 45
Aside: looking back it's pretty amazing what was happening in the late 50s.

Looks promising maybe Barrie was mistaken. I never found mention of one in anyone's antique gear collection and I shudder to think it might have been a unique surviving example maybe even prototype. I had it working 100% in 1970 until I applied too big of a trigger signal and smoked a GE TD11 tunnel diode. Allied actually stocked them at $11 (1970) but the replacement did not work, I suspect the thing was tweeked up by one person who knew what to do. I learned a lot of esoteric stuff from the schematics.
Now that was a challenge. No mention of Tek buying it, though.
http://www.vintagetek.org/wp-content/uploads/2012/01/Tek-History-Anon-RevB-small.pdf Further, the Company had recently been stung by the actions of its arch-rival, Hewlett-Packard, and a tiny firm known as Lumitron. These firms had both announced in 1962 sampling oscilloscopes which represented significant advances in the state of the art; both the H-P and the Lumitron products were elegant approaches to the problem of capturing a high speed signal, while the Tektronix product response (which required the hiring of expertise from outside the Company) was not only a year later, but it also got hung up in manufacturing and when produced showed an alarming tendency to destroy with large bursts of current whatever it was supposed to measure.

http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.471.2710&rep=rep1&type=pdf The Lumatron model 112 sampling oscilloscope was the earliest commercial instrument. The design was clearly derived from Sugarman including the use of the 1N263 as the gate. A 85-ns delay line was used before the input to derive the trigger. A 500-ps pulse was used to strobe the gate diode and advance the staircase generator for the horizontal deflection. The follow-on instrument from Lumatron, the model 220, was an outboard sampler, with connections to a conventional oscilloscope as the readout display

May be related: Lumatron: A high-resolution storage and projection display device - IEEE Journals & Magazine The Lumatron is a high-resolution storage and projection display device that separates the functions of light generation and modulation that are combined in the normal CRT or DVST. The modulation function is achieved in a single vacuum chamber by the formation of a depth-modulated diffraction pattern in a deformable medium with a fine electrostatically focused and deflected electron beam. The illumination function is provided by a single-lens schlieren optical system external to the vacuum. The electron beam and light paths in the Lumatron are coaxial and the maximum voltage required by the device is 7.5 kV. Permanent storage and continuous readout without degradation for more than 24 h is possible, and yet the stored information can be intentionally erased in less than 1 s. Resolution in excess of 1800 TV lines/in at the storage surface has been measured and full 10-step grey scales have been stored and projected. Once an image is stored in a Lumatron, the only power required to generate the display is that required by the light source. In a demountable version of the projector, the storage surface can be easily removed and the stored pattern displayed in a remote schlieren projector without degradation.

Yes amazing stuff, the article makes it clear this was an all in item. I am sure 6CW4's were in my sampling head so I need to look over the patents. I verified 25pS rise times with the included charged line pulse generator (using a reed switch to short it).
EDIT Ironic! that reference mentions burning out the trigger input. 🙂

Patent insurance is not cheap. Neither are patents. Getting an ROI on patents can be quite difficult.
JN, I can connect you with a major suppler of magnetics for the speaker industry and he may be able to make something attainable in a broader sense with their resources. Most magnetics are from a sintered metal in specific shapes. You may be able tyo make a shaped pole that can accomplish what you want with less flux density but lower distortion. It won't have the very special steels but could be a significant improvement. Let me know if you want to go further.

I'd get a third opinion. I am in USA. Timing and conditions may vary from country to country. ??
JN … see a patent attorney before talking to a manufacturer in foreign country..
Demian's sources are usually very capable.

The patent law has been revised to match the rest of the world mostly. If an idea has been published anywhere (including here) before filing you don't get a patent in most parts of the world. If the product has been offered for sale before the patent has been filed same. The US will give you 12 months but that doesn't help much when China starts producing and the EU starts consuming in large quantities.
First to invent no longer exists. If JN privately tells me his idea and I run to the patent office first I win.
If an idea has real value keep in under NDA and file quickly. Keep in mind a patent can cost from $15k to $50K to get if its simple. Make sure it will have value like real estate. You want Park Avenue in New York, not worthless desert. (My name is on a few pieces of that desert...)

BNL?? Nobody of any worth comes from there...😀
Nothin to see here...move along, move along...

with all this talk of sampling for UHf signal measurements..... is anyone here actually doing such work?
I have working sampling units for Tek 7000 series scopes --- 7S12 plug-in with S-6 and S-52 in perfect condition.
Who needs the sampler?
