The protective effect of the resonators series ISTOK®BCN is based on their feature to reduce the negative reaction of the organism to the sharp change of the natural Earth’s electromagnetic hum in the immediate vicinity of a man, including  the effect of electromagnetic radiation of artificial origin.

Efficiency of their practical use is proved by the tests of infrared thermography, medical diagnostics with the help of  the device AMSAT®, the device Аurospectrophotometer 2100, medical diagnostics according to R. Voll.
The prototype of the resonators series ISTOK®BCN is marked with a special prize of jury on  the VIII th  international exhibition of inventions and new patents–«GALACTICA 2001» (Spain)

The following organizations together with Tecno ISTOK BCN took part in research:

• Polytechnic University of  Catalonia (Spain)
• Diagnostic Center Creu Blanca (Spain)
• Specialized Firm in the field of thermographic metrology «Khelkosa» (Spain);
• Center of quantum medicine (Switzerland).

ISTOK®BCN-mob
Protective fractal-matrix resonator  against electromagnetic radiation (REM).
Intended for the compensation of possible negative effects under action of lower  power and high frequency artificial unionized electromagnetic radiation of electronic appliances (300 MHz - 3000 MHz) on a human organism:

• cellular telephones (900-1800 MHz),
  
• radio transmitters (300-900 MHz),
  
• wireless telephones,
  
• consumer  commutating devices on basis of radio frequency.
  

ISTOK®BCN-ord
Protective fractal-matrix resonator  against electromagnetic radiation (REM).
Intended for the compensation of possible negative effects under action of lower-and average power  artificial unionized electromagnetic radiation in broad bandwidth of  50Hz – 1000 MHz on a human organism and is used for computer monitors with cathode ray tube and with liquid-crystal screens, on processors of personal computers, television sets  and other electronic appliances,
