The Institute of Practical Psychophysics has created an analogue-free investigation system, which allows tracing any conditions in the body through changes in the wave characteristics of tissues, cells, chromosomes and even ferments and hormones of the body. Non-linear analysis systems (NLS) are the most advanced information technologies available in this century and can be considered the most remarkable and advantageous accomplishment of modern natural science. The diagnosis equipment is based on the spectral analysis of the vortex magnetic field of any biological object. It is quite unique and unparalleled in the world today. The numerous experiments which have been conducted at the Institute of Practical Psychophysics, have shown a close correlation between the torsion fields and biological systems, specifying that such fields are used in biological systems as the means of both extracellular and endocellular interplays. Principles of entropy logic theory (the informational interchange between any systems is carried out distantly, associatively and is selectively by quanta of electromagnetic radiation) allows stating that in biological systems at pathological processes some unstable (metastable) states may occur, at which the probability of system destruction sharply increases.

    The researches of the Institute succeeded in producing this most effective equipment that is capable of tuning to the frequency of the master pulses automatically without human intervention, as well as, detecting and correcting defects and pathologies in organs and body cell on its own through combination of different specifically modulated magnetic oscillations recorded on a matrix.

    The research system provides a unique opportunity of recording the frequency fluctuations of any preparation and comparing of many thousands already held in the PC database with pathological process’ characteristics and thus finds a remedy that has the closest spectral characteristic of the pathological process and selects the most efficient remedy. After reading the frequency characteristics of the researched biological object, the system compares the degree of their spectral similarity with healthy, and pathologically affected tissue, or infection agents, to obtain the closest pathological process or tendency. "Metatron" system give an opportunity to significantly decrease time of express-evaluation of an organism as a system in a whole and changes in organs and cells, histological and cytological structures.

    All abovementioned allows:

- control effectiveness and results of different therapies;

- evaluate adaptive abilities of organism;

- analyze dynamics of functional state changes of organism during treatment;

- locate primary nidus of functional breach;

- define pathology character, using expert systems;

- predict functional breaches and pathological conditions in organism;

- evaluate basic parameters of homeostasis.

    The information on a particular temporary condition of a biological sub is read contactlessly with the help of a digital trigger gauge, which was developed based on modern information technologies and microcircuitry, catching tiny fluctuations of the signals, filtered from the average statistical noise characteristics of the torsion fields, and converted into a digital sequence processed with the help of the microprocessor for transmitting it via interface cable to a PC.

    The scientists at the Institute then became interested in the experiments of Prof. S. Smith of Manchester University who had proved that water could 'remember' the coherent frequencies of the radiation it was exposed in a variable magnetic field, and retain in it's structure the information about those frequencies for a certain period of time. It means that an effective correction of the disturbed balance within the body can be mended by means of information recorded on a matrix. Information (2002) preparations (metazodes) are specific combinations of coherent frequencies chosen by the computer and are used to provide ready-made dosage forms with a direct effect. They are produced by means of the apparatus that transfers the frequency (spectral) information taken from the pathology nidus into a matrix (water, alcohol, or lactose). The metazodes have the effect of awakening of the body's own hidden reserves, which accounts for the wide area of influence of the preparations and the absence of harmful side effects when prescribed with conventional remedies.

    The hardware-software system Metatron 4025 Hunter enables the production of a preset bioelectrical activity of brain neurons, with this activity as a background it becomes possible to selectively amplify signals hardly detectable against the statistical fluctuations, and then isolate and decode the information they contain. "Metatron" system shows on a display of PC decoded radiation information i.e.: achieve qualitative leap achieved – method of active homeostasis control is developed. NLS analysis system allows revealing within 30 -40 minutes: nosologic forms of functional breaches, diseases, carriage of microorganisms and helmiths by patients, differ carriage from active infectious process, taking into account dispersion and entropy coefficients, choose and make the most effective preparations from allopathy, phytotherapy, homeopathy, nutriaceutics, parapharmaceutics, reveal allergens.
