Some considerations on Iconos' pic
Hi All
1- 4 wires to head, red= +power, black= -power, the others not shielded then DC signals, one perhaps = V/2 power.
2- Tr coil it has many turns, then the frequency may be 1 Mhz, to the
maximum.
3- In appearance it seems that there isn't a Rx coil and the ionic sensor, located near and out of Tx coil, it's the only generator for Rx signal.
4- The loop around the head, with a single turn, it's tuned with small inductor e capacitor, then his resonating frequency is at
least 10 Mhz or more, surely a harmonic frequency of Tx stage.
5- The loop it is connected with nothing but a change in inductance
or a change in the surround electric/magnetic fields it
may change some parameters in Tx coil or in the sensor.
6- There are few electronic components, surely a transistor oscillator for Tx coil, a sensor amplifier and a germanium diode (high frequency rectifier) and IC (a DC amplifier).
Some other ideas?
Best Regards
