How does the FVSA work ??
By measuring frequencies
from over a dozen
Internal organs the
FVSA will show the
Trained Examiner the
Areas of Truth and
The FVSA is a laptop computer loaded with software that will display levels of frequencies produced by internal organs when responses are given from questions asked.
These frequencies produce images
called frequency response prints.
Measured frequency changes
are made between 8Hz-16 kHz
and are regulated by the Autonomic
Nervous System. The frequency
response prints depict changes in frequency release which can be evaluated and quantified.
TRUTH - Non Deceptive
LIE - Deceptive
Deceptive or Non-Deceptive ??

Additional usage for F.V.S.A.
A Military Analyst interviews a source that he suspects has ties to a Taliban group suspected of hiding along the Pakistani / Afghanistan Border. The source confirms that the Taliban has stored a very large cache of weapons on the Pakistani Border however will not reveal it’s location.
The FVSA Analyst produces a map of the areas along the border. The FVSA Analyst describes the areas and marks the areas in “Sectors”.
The source is asked, Are the weapons cache hidden in Sector 1,2,3,4 etc.
The source states “No” in each area. By reverse analysis, the Analyst begins dissecting the areas that deception is determined to smaller sectors. Resulting in a smaller area of search for the Pakistan Military to find the weapons.
Are the weapons hidden in sector 1?
Are the weapons hidden in sector 2?
Are the weapons hidden in sector 3?
Are the weapons hidden in sector 4?
When the individual responds to these questions stating “No”, By reverse analysis, the location of concern will be identified.
After conducting the first examination, a second examination needs to be conducted to minimize the area of search. The area that is determined deceptive will result in the same questions being asked again breaking down the second sector into smaller regions.
Scenario “ Weapons Cache ”

This process has been taught to the U.S. Military and Law Enforcement in several countries to
help locate High Value Targets.This process can be conducted in person, from audio recordings, 2 way radio, body mic’s and telephonically (Cell Phone / Land Line).
Examinations can be conducted over any subject matter when the truth needs to be known.
The F.V.S.A. is the only NATO Codified Instrument available.
There are no language barriers.
Drugs / Alcohol has no effect on the accuracy of the system.
Examinations may be conducted in person, telephonically or by audio recordings.
Scientists valued the F.V.S.A. accuracy levels at 98% in bench mark testing with zero false positives.
IVS-TTS has received no less than 100% accuracy levels in real world testing.
