Hi Morgan, Qiaozhi and all,
Recently I speak by telephone with Alonso, and he said me there are three detectors like the yours in Europe.
He told me is a system with the 2 ferrites and infrared, is a last modification of the detector with only 2 ferrites.
But now is under negotiation with a firm and IS PATENTED.
So, no deppend of me for to be public. Sorry.
