The 3D-NLS device method of analysis was developed at the Russian Institute of Practical Psychophysics. Every organ and every cell has associated with it a biofield magnetic vortex state which is stored in the computer memory and can be displayed on the computer screen as a graph. These graphs represent the conditions of information exchange between the organ biofield and the environment. Every pathological process with distinctive age and sex has its own distinctive biofield graph stored in the computer memory. After reading the biofield frequency characteristics of a patient, the system compares the degree of their spectral similarity with biofields of healthy and pathologically affected subjects, or the biofields of infection agents, to obtain the closest biofield process or tendency. The culmination of all of this science led to the NLS. The NLS device is capable of detecting the biofield frequencies without human intervention, as well as, balancing the biofield imbalances.
