Abstract: Изобретение относится к способам определения координат источников электромагнитных излучений с помощью наземных средств наблюдения путем регистрации и измерения поляризационных характеристик регистрируемого излучения в нескольких пунктах. Техническим результатом является обеспечение возможности определения местоположения самосветящегося объекта и его траектории при отсутствии прямой видимости на него. Способ заключается в том, что при помощи оптического поляриметрического устройства, установленного в каждом пункте, регистрируют рассеянное земной атмосферой световое излучение от сферического самосветящегося источника. Излучение регистрируют в двух оптических каналах, оптические оси которых наклонены под определенным углом относительно вертикали и которые вращаются вокруг общей вертикальной оси. Оптические оси каналов и их общая ось вращения лежат в одной плоскости референции. В каждом канале устанавливают поляризационные анализаторы, у которых оси полного пропускания поляризованной компоненты лежат в этой же плоскости референции. При вращении плоскости референции измеряют амплитуду сигнала от поляризованной компоненты регистрируемого излучения и фиксируют положение плоскости, при котором сигнал в обоих каналах равен нулю, а это значит, что источник находится в плоскости референции. В этот момент в каждом пункте наблюдения измеряют относительные азимуты источника между плоскостью вертикала источника и линией, соединяющей пункты. При дальнейшем вращении измеряют угол поворота плоскости референции относительно зафиксированного положения, при котором в одном из каналов сигнал становится максимальным. По измеренным значениям углов при известной базе между пунктами определяют эпицентральное расстояние источника, его высоту и зенитный угол, используя установленные соотношения. Траекторию объекта можно определить, фиксируя с течением времени изменение значений измеряемых параметров. 2 ил.

Abstract: FIELD: medical tech.SUBSTANCE: invention relates to medical technology. A device for treating disorders of the vestibular apparatus contains a plate for placement in the patient's mouth and an array of interacting electrodes placed on it for generating electrical impulses, a constant magnetic field source and a control circuit. The constant magnetic field source is a magnet located in the device so that it is positioned over the points of tongue stimulation during the procedure. The control circuit generates sequences of impulses, with the help of which the action on the cranial nerves, on the afferent nerve fibers of the trigeminal and / or facial nerves is carried out. Impact is the supply of a constant magnetic field and the supply of electrical impulses. Treatment and prevention of motion sickness symptoms is provided, which would provide a long-term effect and would not require its mandatory use in situations that provoke the symptoms of this condition, due to the electrical effect on the cranial nerves of the patient in the environment of a constant magnetic field, which leads to the harmonization of the significance of the signals from the external sense organs involved in the formation of a sense of balance and body position, which in turn leads to the elimination of the initial conflict between signals that enter the central nervous system from the vestibular apparatus and the organs of vision. Electric impulse exposure against the background of exposure to a constant magnetic field allows influencing the membrane potential of the nerve fiber, which improves blood circulation in the affected area and facilitates the emergence of a nerve impulse in the stimulated nerve.EFFECT: neuroplasticity is enhanced, providing more rapid training of the brain in new skills, in particular motor skills and the ability to maintain balance.7 cl, 3 dwg

Abstract: FIELD: acoustics. 
     SUBSTANCE: area of application: the invention relates to the field of hydroacoustics, can be used in solving problems of processing the noise emission signal of an object in hydroacoustic systems, and is intended for determining the parameters of movement of a detected object. Substance: the method is based on continuous reception and processing in the low-frequency range of the noise signal of the object by a hydroacoustic antenna, determining the frequency of the maximum harmonic in the spectral composition thereof at consecutive times. In implementation of the method, an array of measurements of a fixed length is created and supplemented with the values of the maximum harmonic frequencies at each of the consecutive times using a sliding window therefor. When the array is completely filled, the value of the frequency change rate V is formed from the elements thereof, using the least-square method. It is decided that the object has increased (decreased) the speed of movement, if V>0 (V<0), it is decided that the object maintained the speed, if V=0. 
     EFFECT: reduction in the amount of false decisions on the presence of a change in the speed of movement of an object and determination of the numerical characteristic of this change.

Abstract: FIELD: electrochemical protection of underground structures. 
     SUBSTANCE: invention relates to electrochemical protection of underground structures against ground corrosion. A well is drilled that is parallel to the structure protected at the groundbed location and is below the groundwater level and the soil-freezing level. The structure – earth potential value is measured in relation to the copper-copper sulfate electrode. The anode grounding site is divided into intervals described as having different protection potentials. Intervals of safety and lightning-protection earths’ impact on the parameters of cathodic current emergence at the structure protected are determined. The structure – earth potential value in these intervals is reduced in absolute terms because cathodic protection current is shielded by the protection earth elements, electrically connected with the cathode-protected structure. At this interval, pipes are installed in the well drilled, resembling two connected half-shells made of materials featuring different electrical resistance values. While the pipes are being installed a pipe is placed so that the half-shell made of a material with higher electrical resistance value is turned to the protection earth. The construction comprising two half-shells welded together is connected with pipes made of a conductive material and protective electrodes are pulled inside with the subsequent filling of a conductive solution.  
     EFFECT: longer service life of the anode grounding given the detrimental effect of the elements of the safety and lightning-protection earths on current distribution parameters in the cathode protection system.

Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to the oil and gas industry and can be used to develop a zonal heterogeneous oil reservoir, in particular to involve in the development of low-permeability zones of the reservoir. The method includes opening an oil reservoir with a vertical well, drilling a sidetrack with an entrance at a distance from the main vertical wellbore, excluding their hydrodynamic connection, initiating the formation of cracks through the sidetrack into the reservoir, pumping a displacing agent and producing reservoir products. In this case, vertical boreholes are drilled along any of the known reservoir penetration grids with a division into injection wells for pumping a displacing agent and production wells for production, determine low-permeability zones of a reservoir with a permeability at least two times less than the average permeability of the reservoir. Sidetracking is carried out into low-permeability zones from nearby wells, in which the formation of cracks in the exposed zones is initiated by thermobarochemical and/or acoustic-seismic action with equalization of permeability to the average permeability of the reservoir and isolation of the sidetrack. 
     EFFECT: proposed method makes it possible to level the permeability of a low-permeability zone with an average permeability of the reservoir to level the displacement front and increase the drainage of oil and, as a consequence, increase the oil recovery factor of the reservoir.
