6 2. Literature review and problem statement The main software solutions that implement the methods and algorithms of EIT can be divided into two groups, shown in Fig. 1. Group D packages have enhanced functionality for the design and development of software and technical solutions in the area of EIT. However, their main drawbacks are the need for additional software installation, the lack of multiuser access, especially online. Group W solutions are open, highly informative software solutions that differ from Group D in less functionality (for example, a resource [3]) and do not provide the possibility of solving online reconstruction problems. The resource [4] implements only the algorithm of static reconstruction of EIT-differential algorithms are not presented. One of the solutions to these problems is the creation of a specialized Web portal that includes the capabilities and functions of both special systems of group D and the

“…Проблемы получения достоверной информации об электрических параметрах и временной активности точек акупунктуры В ходе обзора источников по данной проблематике было выявлено, что в большинстве исследований электрического сопротивления точек акупунктуры используются аппаратные решения на основе методов Фолля или Накатани [2-4], а также устройства, работающие в режиме заданного тока, которые не могут обеспечить необходимую достоверность получаемых результатов [5][6][7][8]. Возникают варианты измерительных устройств с измерением биоимпеданса [9,10], в том числе на основе интегральных схем типа AFE [11]. Предлагаются варианты измерительных систем для построения вольт-амперных характеристик точек акупунктуры с помощью токовых посылок ступенчатой формы (в диапазоне токов от -30 до +30 мкА) и с циклическим воздействием токами разной полярности [12][13][14].…”

The paper presents the results of an experiment to test various hypotheses about the biorhythms of acupuncture meridian activity by analyzing the results of measurements of electrical resistance at acupuncture points. In known studies, measurements are carried out using the hardware base of the Nakatani and Voll methods, as well as their modifications and various variants of bioimpedance methods. Such approaches do not allow organizing, in the case of biologically active points with different electrical resistance, the same energy disturbance introduced into the object during the measurement process, and, accordingly, to obtain sufficient reliability and reproducibility of the results. When analyzing the biorhythms of acupuncture points, other researchers do not take into account the influence of time zones and other factors that contribute to the shift of local time from the time of solar activity. The calculated intervals obtained using different methods for determining the time of activity may not even intersect. The authors have tried to avoid the shortcomings found in previous studies on monitoring electrical resistance at acupuncture points. The measurements were carried out using a two-channel measuring system based on a measuring generator with the prescribed electric power. A decrease in electrical resistance at the C7 acupuncture point in the calculated range of activity of the heart meridian was registered. The analysis of the experimental data confirms the correctness of using the refined methodology for calculating the time of activity of acupuncture meridians with reference to the moments of sunrise and sunset. The decrease in electrical resistance is various for different age groups. The use of measuring generators with the effect of prescribed electrical power makes it possible to obtain new data on biological objects, due to the implementation of the measurement mode with a fixed effect of the value of electrical energy, independent of the resistance of the object.
