Description

The invention relates to medicine. Specifically, to a method of reducing the negative impact of a cell phone on a person.

The well-known "Method of protecting a person from exposure to electromagnetic fields emitted by a cell phone" [Pat. RF №2381042, class A61N 1/16, G12B 17/02. Publ. 02/10/2010]. The way to protect a person is to use a metal mask of a fencer, in which holes for the eyes and mouth are made, place it on the head of a speaker on a cell phone, then attach a flexible electric wire to the mask, which, in turn, is connected to the grounding system in premises with electrical equipment and electrical installations in which negotiations are ongoing. It is believed that the mask connected to the grounding system is at zero electrical potential. But this is not so.

A grounding device is a combination of a metal grounding conductor in contact with the ground and conductors connecting the grounding parts of various devices to the grounding conductor. At the boundary of the ground electrode system with the ground (aqueous medium), a double electric layer (DEL) is formed, which is an ultra-low-frequency generator of electric and acoustic vibrations [Activated liquids, electromagnetic fields and flicker noise. Their use in medicine and agriculture: Monograph. / O.A. Pasko, A.V. Semenov, G.V. Smirnov, D.G. Smirnov. - Tomsk: Tomsk, state. University of Control Systems and Radio Electronics, 2007. - S. 152-153]. The upper frequencies of electrical oscillations at the boundary of the ground electrode system with moist earth do not exceed several tens of hertz. DES is a nonlinear object and acts as a detector, mixer, and modulator. On the grounded parts of the devices there is a noise potential difference. At the same time, the grounded parts of the devices, including the fencer's mask, are affected by acoustic vibrations of the DEL. The spectral composition of noise is determined by the material of the ground electrode, the humidity of the earth, the chemical composition of the aquatic environment, the temperature of the earth and the ground electrode, and other factors. An earthed mask can also be considered as an antenna, the nonlinear load of which changes in time stochastically (note that any antenna re-radiates part of the power incident on it, including interference of natural and artificial origin). The fencer's mask connected to the grounding device is the end part of the antenna and therefore cannot protect a person from the negative influence of a cell phone.

The well-known "Method of forming a stimulating effect" [US Pat. RF №2053803, class A61N 1/00, 2/00, 5/00. Publ. 02/10/1996]. The method is used for the treatment and rehabilitation of patients using various physical factors, in particular an alternating magnetic field (MP) containing a flicker-noise component. Flicker noise (FS) is also called 1 / f noise, where f is the frequency. The device that forms the variable MP contains a source of a low-frequency FS signal, an amplifier of these signals, and a portable device “Pole 101” used for low-frequency therapy. The Pole 101 apparatus includes low-power sinusoidal oscillators with operating frequencies of 700 and 1000 Hz, a multiplexer, an electronic relay, a power amplifier, two inductive coils, two LED indicators and two capacitors connected in series with inductive coils and forming two successive resonant circuits tuned at frequencies of 700 and 1000 Hz. LED indicators connected to the coils begin to glow at a given value of magnetic induction in excess of 25 mT. In the spectra of currents flowing through the coils, the FS component is an insignificant part. The MP emitted by this device can be used to reduce the negative impact of a cell phone on a person. However, the effectiveness of human influence of this MP will be insignificant, since the frequency spectrum of the MP is not optimal for these purposes. The magnitude of the magnetic induction of this device is unreasonably high. We note that the magnitude of the induction of the most powerful magnetic storm does not exceed 0.5 μT.

It is known "Device to reduce the impact of negative effects from a cell phone on a person" [Pat. RF №2186585, class A61N 1/16. Publ. 08/10/2002]. The device contains a rectangular substrate made of porous magnetized rubber, on top of which is placed the first rectangular applicator made of permalloy tape. On the bottom side of the substrate is a second rectangular applicator made of a sheet of copper. All three elements are combined into a single structure in the form of a truncated rectangular pyramid, the first applicator being the large base, the substrate being placed in the general structure so that the N-pole of its magnet is directed towards the first applicator. In the middle of the assembled structure, a regular multi-beam star is cut out, the number of rays of which is chosen at least five and no more than nine. The total thickness of the device does not exceed 4 mm. The device is pressed with one applicator to the auricle, the other - to a cell phone (applicator, from lat. Applico - I attach, I press). The disadvantage of this device is the inconvenience of its use. In everyday life, this device is not used.

It is known “Device for protecting a person’s head from the effects of physical fields” [Pat. RF №2012963, class H01Q 17/00. Publ. 05/15/1994]. The device is made in the form of a hoop worn on a person’s head made of an electrically conductive tape perforated along its entire length, the thickness of which is 0.1-0.6 mm, width 10-30 mm. The element of fixing the tape on the head of a person is made with the possibility of adhesion of the ends of the tape when overlapping them. Each perforation hole is made E-shaped and is located across the tape. The fixing element is a rib with reed protrusions that frame the perforation holes. The disadvantage of this device is that it protects the head from microwave electromagnetic fields only under the hoop and partially from anthropogenic low-frequency magnetic fields, the components of the magnetic vectors of which are directed along the axis of the hoop. Using such a hoop to reduce the negative impact of a cell phone on a person is impractical.

Known "Means for protection against electromagnetic radiation" [US Pat. RF №2214841, class A61N 1/16, H01Q 17/00. Publ. 10.27.2001]. The tool (device) is made in the form of a ring worn on the head or other part of the human body. The tool is formed by a knitted fabric made of flexible stranded wire with an insulating coating, and rolled into a ring, while the beginning and end of the wire are galvanically connected to each other. The clearance between the rows of loops of the web does not exceed 6 mm. The width of the web is in the range of 6-10 cm. The product is intended to protect parts of the body from electromagnetic low-frequency radiation. It is not used to protect a person’s head from radiation from a cell phone.

We will not dwell on stickers like “Anti-Radiant on Cell Phones” (www.kzb.ru/antiradiant.html), which supposedly neutralize their harmful radiation. This is an unprofessional fraud of buyers.

There are ways to reduce the negative effects of a cell phone in a clothing pocket or in a case using a protective screen located between the phone and the human body, for example, using the "Protective screen to reduce the microwave radiation level of cell phones" [Pat. RF №128790 U1, cl. H1Q 17/00. Publ. 05/27/2013]. The protective screen consists of parallel layers of materials, including an absorber (matching layer) made of a material based on a binder and containing an absorber of electromagnetic waves, a reflector of electromagnetic waves and a protective and decorative coating. The absorber is made of a binder-based material containing a mixture of microwave ferrite powder and carbon nanostructures with a mass ratio of approximately 9: 1 in a total amount of 48-52 wt.%, And the reflector is made of a non-metallic material based on a binder containing 10- carbon nanostructures 15 wt.%. A protective screen is located between the phone and the human body. In this case, the reflector is located closer to the human body, and the thicker matching layer is closer to the cell phone. The protective screen allows you to reduce the radiation level of a cell phone no more than twice. It is advisable to use it only in the standby mode of a subscriber call.

Patent studies have shown that currently there are no effective ways to reduce the negative impact of a cell phone on a person.

The task to which the proposed method is aimed is to reduce the negative impact of a cell phone on a person.

As a result of the experimental studies, which are described below, it was found that the solution to this problem is achieved by the fact that during a telephone conversation they affect the FSH MP in contact with it, the maximum induction of which in the region of the auricle is chosen within 2-5 μT FS FS are formed by a flat multilayer inductive coil located in the cell phone from the side applied to the auricle, and when a subscriber calls or answers a subscriber’s call, the coil is connected posted in cell phone PN generator current. The operating frequency of the FS generator is selected in the range of 0.005-100 Hz. In a particular case, in the initial FS spectrum of a cellular telephone, frequencies are excluded that can be used to modulate the carrier frequency of the base station, for example, for GSM phones - 2 and 8.35 Hz, and the first and second harmonics of an industrial frequency MP, in particular 50 and 100 Hz . In a particular case, in the standby mode of a subscriber’s call, a flat protective screen is placed next to the cellphone in the pocket of the clothes, or next to the cellphone in the case and suspended by means of a piece of tape with a loop on the strap or other part of the clothes. the layers of the absorber and reflector of electromagnetic radiation and two external protective and decorative layers, the layer of the reflector is closer to the human body than the layer of the absorber.

We studied the effect of a magnetic field formed on the basis of the FSH signal on an electroencephalogram of a person while waiting for a call from a subscriber and during a call of that person by a subscriber with a disconnected call. The effect on a person’s electroencephalogram was also studied while waiting for a call from a subscriber and during a person’s call by a subscriber (without a call) in the absence of FS MP. A FS signal was generated on a computer using a specific program. For the study, FS was used, the spectrum components of which were inversely proportional to the frequency. The study involved 10 volunteers aged 19 to 25 years (seven men and three women).

The experiments were carried out in two adjacent rooms of a three-room building. In these two rooms there were two Mitsar-EEG 03 / 35-201 electroencephalographs mounted on floor stands, two personal computers (PCs) and two special T-shaped floor tripods that allowed changing the height of the upper horizontal part made of a metal tube, and move this tube along its longitudinal axis. At one end of the handset was a gripping unit, enclosing a cell phone and an inductive coil connected together. Floor stands made it possible to optimally bring cell phones with inductive coils to the subjects' right ears, which were sitting in comfortable chairs. The databases of the two PCs were combined using a two-wire cable passing from one room to another. EEGs were connected to their PCs with pieces of two-wire cables ending in the corresponding cable parts of the connectors. Information channels of electroencephalographs were connected to the signal inputs of the PC. The power supply voltage to the BSS came from the PC system units (from the USB ports).

Before the study of volunteers in all rooms of the room, devices powered by an alternating voltage network of 220 V were switched off, except for those participating in the experiment. The value of magnetic induction was measured at a frequency of 50 Hz. In all cases, before the start of the experiment, it did not exceed 0.2 μT.

Volunteers used caps with electrodes, in which the electrodes were placed according to the "10-20" system. The beginning 19 insulated wires were galvanically connected to the cap electrodes, the ends of which ended with pins, inserted into the corresponding sockets located on the front side of the electroencephalograph.

Electroencephalographs had the following main technical characteristics:

The number of channels. 19 EEG Bandwidth 0.53-35 Hz Input impedance More than 200 megohms Internal noise level Less than 0.25 uV Input range 5000 μV ADC 16 bit Sampling frequency 500 Hz Interface USB Food From USB port

The functional diagram of the device for creating FS FS in the cell phone area is shown in FIG. 1, on which is indicated:

2 - power source of the current generator;

3 - socket part of the connector of the FS generator;

4 - the first segment of a two-wire cable;

5 - cable part of the connector of the first segment of a two-wire cable;

6 - bipolar switch;

7 and 8 - the first and second inductive coils;

9 and 10 - the second and third segments of a two-wire cable.

Devices and nodes 1-6 and partially 9 and 10 were in the third room, inductive coils 7 and 8 and parts of the second and third segments of the two-wire cable 9 and 10 were in the first and second rooms.

Inductive coils were made of thin insulated wire, which was passed into a polyethylene tube rolled into a ring. The ends of the coils were soldered to the first ends of the segments of two-wire cables 9 and 10 that went into the third room to the two-pole switch 6. The ends of the polyethylene tubes and the first ends of the second and third segments of two-wire cables 9 and 10 were located in protective devices consisting of two rigidly connected parts, in which there were grooves for the clamped ends of the polyethylene tube and the first ends of the segments of two-wire cables 9 and 10. In the initial state, the coils were flexible and had a loop shape. Coils were worn on the longer ends of the cell phones and wound to these parts with adhesive tape. In the experiments used cell phones standard GSM-900.

The functional state of the human brain according to the fluctuation characteristics of its electrical activity, reflected in the indicators of the electroencephalogram (EEG), was used as an indicator of the effect of radiation from a cell phone.

The experiment for each pair of volunteers lasted 27 minutes. Within six months, each pair conducted three studies (a series of tests). Periodically, at the fourth, eighth, twelfth, sixteenth, twentieth and twenty-fourth minutes, both subjects were sent telephone calls for one minute without turning on the call. The first subject, from the fourteenth to the twenty-seventh minute, was supplied with an FS current (to create an FS MP) to an inductive coil. In the second FS test, current was supplied to the inductive coil from the first to the fourteenth minute. At the twenty-seventh minute, the experiment was completed. Switching the current in the coils was carried out by a bipolar (two-channel) switch 6 (Fig. 1).

The results of all tests were recorded in a common database of both PCs in the form of time series of EGG amplitude potentials. In the process of analyzing the experimental data on the basis of the Fourier transform, we calculated the maximum values of the voltage fluctuations of the signals in minute intervals in the frequency ranges: 2-4 Hz, 4-8 Hz and 8-3 Hz for all 19 EGG channels for each subject. Based on these data, tables were compiled and histograms were constructed. Note that the analysis of signals in the frequency range 2-13 Hz is important in terms of information on the influence of various physical factors on the human brain.

In FIG. 2 (a, b), 3 (a, b) and 4 (a, b) show the distributions in relative units (A, rel. Units) of the maximum fluctuation values in the EGG parameters of two subjects (men and women) for frequency ranges 2 -4 Hz, 4-8 Hz and 8-13 Hz - averaged data for a series of experiments.

An analysis of five series of experiments revealed the following patterns. When a cell phone was exposed to a person in the first 13.5 minutes in the first minutes after the subject’s minute call without exposure to FS MP, a significant increase in the maximum fluctuation level was observed. After about a minute, these changes began to return to their original level. This effect was manifested in all experimental series in three frequency ranges selected for investigation (Figs. 2, 3, and 4). After turning on the FS FS, in most cases a decrease in the maximum fluctuation level was observed in the first minutes after the test subject was called without a call. The average data from the results of five series of experiments yielded such results. Without using FS FS, the increase in the maximum fluctuation level after a minute call of the test subject was in the range of 2-4 Hz - 21%, in the range of 4-8 Hz - 17% and in the range of 8-13 Hz - 7.5%. When the FS current was supplied to the inductive coil, the decrease in the maximum fluctuation level after calling the test subject reached 66.5% in the range of 2-4 Hz, 55.5% in the range of 4-8 Hz and 55% in the range of 8-13 Hz.

Based on the studies, it can be argued that the FS-MP blocks the increase in the level of radiated power of GSM-900 standard cell phones from the subscriber when he calls and speaks on the phone.

Thus, the technical effect of the proposed method - reducing the negative impact of a cell phone on a person - is not in doubt.
