What "it"? Devices are being discriminated by their signature. Various sensors are doing this. Do you know how many MP3 players are out there? Yeah, so what. There are devices that can detect semiconducter junctions. MP3 players have semiconductor junctions, hence they can be detected. Now how about the phones that can record? They also have semiconductor junctions, hence they can also be detected. A theory about what might be possible someday, is not same thing as what IS being done today. Semiconductor junctions can be detected today. You seem to be vaguely claiming it's possible without really considering EXACTLY what is necessary. Hogwash. You seem not to understand what can be done with electronics. There are some devices that use the priciples of a MRI and shrink it down to a hand held sized device to scan for explosives. Since the compounds in explosives give off a unique signature after being exposed to a strong magnetic field, that signature is then stored in memory. Now your sensor emits a magnetic field, and the reciever looks for the signature of the explosives. So it is only a matter of expanding your signature library, and your receiver can be programmed to look for pretty much anything. This is only one of many new tools that are out. The semiconductor junction detector has been out for around 30 years. |
