Dizzy Beam

anti-terrorist application

  • Microwaves can be absorbed by the body and under specific conditions can activate the vestibular system to produce dizziness or temporary paralysis.
  • Delivery can be in the form of a hand held device (radar gun) for individual targets or in the form of a barrier for securing a protected area.

The balance system in the ear is sensitive to microwave radiation.
Microwaves activate the semicircular canals which in turn induces eye movement.
US Patent #6,250,255 Method and apparatus for alerting and/or repelling birds and other animals. Lenhardt and Ochs.

Speech Interruption

additional feature to dizzy beam

  • Speech can be modulated on microwave beams and this can be used as an "interference" message as a means of disrupting terrorist communication.
  • The speech messaging can be as a stand alone feature or incorporated into the dizzy beam.
  • The beam can be targeted to one individual even in a crowd.
  • The beam travels at the speed of light.

Limitations
  • The use of microwaves to produce thermal effects (heating) are limited by power needs. The detection of speech or the induction of dizziness takes less power.
  • No hand held prototype devices have been built but police radar modification seems a good first start.
