ENCYCLOPEDIA OF RADIO ELECTRONICS AND ELECTRICAL ENGINEERING Psycho-emotional correction device. Encyclopedia of radio electronics and electrical engineering Encyclopedia of radio electronics and electrical engineering / Electronics in medicine Radio-electronic devices for correcting the state of the body make it possible to control its state by non-drug means. In devices of this purpose, the impact can be made through visual [1-5], auditory [6, 7], tactile [7, 8] analyzers, as well as using the electromagnetic channel for "pumping" the body [9-11]. Signal transmission in the latter case is carried out, as a rule, not at the energy level, but at the information level. Such a signal transmission mechanism is the most physiological and as close as possible to natural, which allows, operating with negligible power, to cause a significant and tangible response. Currently, quite a lot of devices and methods of rhythmic stimulation are known: audio, light, electromagnetic stimulation [1...11]. The proposed device for psycho-emotional correction uses an electromagnetic channel for transmitting information. The device is based on a relaxation pulse generator [14]. When consuming a negligible current (tenths of a milliamp) from a power source, the device generates very short powerful current pulses (delta pulses). Such pulses have a high penetrating power and are able to "leak" through thick screens. The device works as follows: the capacitor C1 is charged through the resistor R1 from the power source. When the voltage on the capacitor reaches the avalanche breakdown voltage of the transistor VT1, the accumulated energy is instantly discharged into a chain of series-connected oscillatory circuits L1, C2 and L2, C3, after which the accumulation-reset process is periodically repeated with the time constant T = R1C1. As a result of shock excitation of the system of oscillatory circuits, damped electromagnetic oscillations are generated in the latter. The damping rate of oscillations is determined by the quality factor of the oscillatory circuits. Since two (or more) oscillatory circuits are simultaneously excited, a frequency spectrum is generated, consisting of the resonant frequencies of the circuits, the excitation frequency, the products of the interaction of the listed frequencies and their harmonics. When ferromagnetic materials are used as cores of inductors, at the moment of excitation of the oscillatory circuit, the core is saturated, and therefore, at the initial moment of excitation, a wide range of harmonics is generated, the level of which decreases as the amplitude of the first harmonic decays. At the same time, the quality factor of the inductor also changes. Oscillatory circuits can be tuned to odd harmonics of the original signal, which provides the formation of ultra-narrow delta pulses. Thus, the device generates delta-like impulses in the range of natural biological rhythms (in this version of the device - beta rhythms). Reception of delta impulses by a person is supposedly carried out through biologically active points and zones. Detection (reception) of signals is carried out due to the non-linear nature of the interaction of the radiation incident on the surface of the body with natural biosemiconductor detecting structures, and the transmission and processing of stimulating signals is carried out through internal traditional signal transmission channels. When using a rhythmically repeating (and slowly decreasing in frequency) sequence of stimulating impulses, a state occurs that promotes muscle relaxation, calming, better falling asleep, and relieving stress and shock conditions. On the contrary, a sequence of impulses increasing in frequency, in combination with the internal target setting (setting) of the body, causes a tonic effect, stimulating the extinct or atrophied function of this organ. A sensor plate electrode (electrodes) is connected to the base of the avalanche transistor VT1, which allows, due to capacitive coupling with a common bus or power bus through the human body, to control the frequency of generation of a relaxation pulse generator [14]. If a second person (physician) is involved in the scheme of influence on the patient, he can contactlessly control the operation of the generator through the sensory system. The microassembly transistor K101KT1 of the npn structure can be replaced by the microassembly transistor K162KT1 of the pnp structure with a change in the polarity of the power source. Approximate parameters of the device elements; the initial generation frequency is about 30 Hz, the resonant frequency of the first oscillatory circuit is 690 Hz, the second is 10,35 kHz (i.e., odd harmonics of the excitation signal are used). The inductors are made on ferrite closed magnetic circuits. In order to optimize the shape of the generated pulses, the number of oscillatory circuits can be increased. Attention! It is advisable to consult a doctor before using this device. Literature 1. Chuprikov A.P., Linev A.N., Martsenkovsky I.A.
