look at the applet on this page.....
..and then look at the open TPU unit...

Dan, right track, I've had suspicions about metal detectors and magnetometers for a long time.

Have you read how they work?

There are two basic kinds.

A VLF metal detector, and a magnetism sensing metal detector (BFO).

Both have a transmitter and detector(receiver coil)

A transmitter flips the charge polarity in it's coil many thousands of times per second. this flip is the frequency.

This causes eddy currents in metal, which as you know is caused by proton, and electron precession. Precession emits vlf radio waves, which is picked up and magnified by the recieiver coil, which is basically an antenna.

In a magnetic sensing metal detector, the second coil has it's own circuitry, which is basically a sensitive magnetometer.

The transmitter coil works the same inducing eddy currents in the metal object, but instead of trying to detect the vlf, it focuses on detecting and utilizing the magnetic field that is created by the induced eddy currents in the metal.

I believe the TPU uses both of these types of reactions in it's operation in some form or another.

The flipping frequency in the transmitter coil is the key to what you will see at output.

Three rings, three devices which interact with eachother at different frequencies.

There is another type as well, that I had forgotten about. It's called a PI metal detector.

Here's a description.

A less common form of metal detector is based on pulse induction (PI). Unlike VLF, PI systems may use a single coil as both transmitter and receiver, or they may have two or even three coils working together. This technology sends powerful, short bursts (pulses) of current through a coil of wire. Each pulse generates a brief magnetic field. When the pulse ends, the magnetic field reverses polarity and collapses very suddenly, resulting in a sharp electrical spike. This spike lasts a few microseconds (millionths of a second) and causes another current to run through the coil. This current is called the reflected pulse and is extremely short, lasting only about 30 microseconds. Another pulse is then sent and the process repeats. A typical PI-based metal detector sends about 100 pulses per second, but the number can vary greatly based on the manufacturer and model, ranging from a couple of dozen pulses per second to over a thousand

sound familiar?
