Will we ever see new advantages with new machines/technology?

[juit]

Well i think it wont improveuntil they lift ban of led circuits, i dont know were i read it but it sure messing this up

Isnt pulse and vlf not compatibles?

VLF detectors work in frequency domain. Pulse detectors work in time domain. The signal processing is entirely different. VLF detectors work on phase shifts, where as PI detectors work on time decay of the reflected pulse. I am sure some clever engineer could find a way to blend the two.

With the correct math, you can transform a signal from frequency domain to time domain or a time domain signal into a frequency domain signal.

Our eternal thanks to Jean-Baptiste Joseph Fourier for having come up with the correct math.

I didn't want to introduce the concept of the various Fourier transforms. If what I posted previous hurt Juit's head, higher math may cause his head to explode.

Hahahahha thanks

Can't help it, it's my EE background coming through. Jean-Baptiste Joseph Fourier, Pierre-Simon Laplace and Leonhard Euler are three persons you learn to be grateful for.

 

[juit]

I hope they launch it

With no new advancements in many years other than improvement in coil design has VLF detection reached its limits?
There is talk about improvements involving separation but has there really been any advancement ?
Look up nail board tests involving newer v/s older machines but be ready to start scratching your heads at eye opening results!

I think there has been quite a few advancements -

better separation
better for people with disabilities (visual & hearing)

are just a couple - might not be important to some but to others they are a godsend

 

[juit]

You are right

My degree is in EE as well. Never worked a day in the field though. Been doing software since I got out of college.

I wish I detected while I was in college. I may have paid a bit more attention in Emag Theory.

Good to have another EE on the forum.

so when this new tech will be available?

so when this new tech will be available?

When a manufacturer finishes developing it, testing it, and QCing it.

Keep in mind that these things only get developed if the finance people see a business case for which their R&D money will be recouped as well as a chance for profit.

Engineers work at the dictate of the finance people.

Oo i tought it was going to be released soon like this year or something

VLF technology (and I include FSB as a variety of VLF) has pretty much reached it's peak. Improvements to it are fractional and not dramatic....

Well said Rudy. The subject comes up on forums frequently: How come we saw so many vast leaps improvements in the 1960s, 70s, and '80s ? Back then if you had a detector a mere 5 yrs. old, you had a dinosaur ! But NOW, the improvement in the last decade or two are miniscule. YET IN THE SAME LAST 2 DECADES: the improvements to other electronics has been astounding! computers, digital cameras, cell-phones etc... Eh ? Hence why not detectors too ??

But it's as you say: There is the durned laws of physics. Everything that can be said of computers, cameras, and cell-phones are all a function of "faster and smaller". But when it comes to detectors, NO AMOUNT of "faster and smaller" is going to change the fact that they have to see through solid ground. And you can't change the laws of physics.

Thus it's not a matter of "lazy engineers asleep at the wheel" (as one poster one time griped).

Unless something entirely different came along , that is not reliant on present send/receive signals of VLF, pulse, etc...

Glad you agree Tom.

As long as the technology is one based on inducing an Eddy current on the target and then trying to sense the resulting magnetic field generated by the target, we are at the limit of making big changes in performance, except the one I mentioned: better battery technology/chemistry, to let us make big changes in the coil's transmit power, while still having a detector of reasonable weight and operation time.
