ML patent Application

[Davor]

Phew, that was deep. I thought I knew the meaning of a word expired.

I'm not under any pressure to finish my detector any sooner than I'm feeling comfortable to. It is my hobby, the thing I do for fun. You know, the stuff you enjoy? Oh, I see the blank stare in your eye. I know, corporate trolls don't have fun. Like never. You wouldn't understand that.

BTW, I've seen some silly timing schemes in that expired patent that obviously did not impress NATO as they picked a better detector for their UXO purposes. Competition sucks. Real competition double sucks.

.. the expired patent copied from the original Poole's design? Oh yes, lesson learned thank you very much.

Gee Davor, lets see you achieve Minelab performance by using the methodology of Poole. Talk about a clown who it appears wouldn't know what a patent was let alone have the ability to understand one.

For someone who has stated that he would ensure his detector would be the best there is, it appears you sure do have a long way to go, Davor. If you cannot see the difference between Poole's methods and Minelab's then there is no hope for you.

When its examined (i believe it will be) details may become publicly available.

Thanks. I missed that detail.

[Davor]

that is if they do have the intelligence

... to avoid being bruted by the company sharks and a broken patent system that provides racket type protection even for the expired patent copied from the original Poole's design? Oh yes, lesson learned thank you very much.

Is there any humane way of peeking into this? Perhaps only the Croatian patent database is less co-operative than this one. It so beautifully demonstrates how monumentally patents miss the whole point

Another ML patent.Will be very interesting to see what its about!

if a piece of ferrite(that is not normally detectable) is waved over this piece of metal, the ferrite will give a response. Try it and see. It is only relevant to solder joints in the coil itself as they may be exposed to ferrites in the soil.

Cheers Mick

Hell Mech. Don't give the game away! You will have blokes here finally understanding that Minelab patents do have relevance...(that is if they do have the intelligence)

[Mechanic]

Any metal on a coil(pi) that is able to support eddy currents into the sampling periods, although it is fixed to the coil(not moving relative to the coil windings), if a piece of ferrite(that is not normally detectable) is waved over this piece of metal, the ferrite will give a response. Try it and see. It is only relevant to solder joints in the coil itself as they may be exposed to ferrites in the soil.

Wow. I was trying to do more Google research on eddy currents in solder joints and eventually came up with this search string:
"pdf Performance Optimization of Local Magnetic Resonance Surface Coils and Antennas"
It comes up with a bunch of PDF reports on designs of coils and electronics for MRI systems. Some of it really interesting with cool technology. They don't seem too concerned about solder joints though.... :-)

[Mechanic]

The way to avoid the problem in the first place is to have a litz coax cable with the same amount of strands as the coil wire and solder and insulate each of the strands individually.

Cheers Mick

yes it wiil be, I'm always looking for new ideas.....

No. Ferrite magnetically shields the solder droplet from creating eddy currents, which is a non-issue in case you are not criminally messy in your welding. Perhaps it is a way of hiding the balancing means with the unsuspecting beads, rendering the off-balance coils unrepairable to the uninitiated ones, hence the techno babble gobbledegook in the patent. Smokescreen and mirrors.

Non ML coil manufactures will not be able to use this method (patent infringement!) with their coils and perhaps future ML detectors will only be optimized for,or only work with ML coils?

Hi All,

I'm having personal issues with my computer,I seem to be able to push the right buttons now, 5th time rucky....Ok!!, right!!,...I seem to recall "Woody" saying that he uses leadless solder to join the coax to the coil wires, I have been doing this but i don't recall the reason why....anyone!!!!?

"which is a non-issue in case you are not criminally messy in your welding."

That's a good way of putting it.
