Background: Portable life support system is used in the battlefield, disaster and in other special circumstances such as in space exploration, and underground survey to give the wounded a life support. The most dangerous period for the injured is the first hour after an injury, which is a crucial time for treatment. If the patient's vital signs were stabilized, more than 40% of the injured could be saved. The staff can efficiently complete the task if they get effective and stable vital signs during the operation. Therefore, in order to reduce the risk of disaster and battlefield mortality to improve operational safety and efficiency, it is necessary to study the portable life support system. Objective: The study aimed to provide an overview of recent portable life support system and its characteristics and design. Methods: This paper introduces the patents and products related to a portable life support system, and its characteristics and application. Results: This paper summarizes five kinds of portable life support systems which are box type, stretcher type, bed type, backpack type and mobile type. Moreover, the characteristics of different portable life support systems are analyzed. The paper expounds the problems of different types of portable life support systems and puts forward improvement methods to solve the problems. Finally, the paper points out the future development of the system. Conclusion: Portable life support system plays an increasingly important role in health care. In terms of the structure, function and control, further development and improvements are needed, along with the research on portable life support system.

The territory and its natural frame are the arena of all chemical, biological, technical interactions and processes, and the wind and rain are their natural propellers. The cartographic image of space, as an integral indicator of processes, phenomena, carries the function of a guide mark in the basis of control and regulation of durability and protection of structures in the natural frame. This article presents the results of a city life support system simulation in the light of the concept of forecasting and managing the risk of the danger of air pollution, including in the practice of anti-corrosion protection. Monitoring of the surveillance and control system grows into the life support system of the territory. “Technologies at a glance” provide: an assessment of the fields and halos of danger from air pollution (real and predicted state maps), modeling “alive geofilters”, namely, purification methods, preventive protection measures, formation of city breeze corridors or wind tunnels.

The article analyzes the problems of the manifestation of risks of shadow and criminal activity in the life support system of citizens of the Russian Federation, the dissemination of which requires the development of effective measures to prevent and eliminate them. The most important issue is the formation of an effective economic security system with an emphasis on the new quality of life support for citizens of the Russian Federation in an adequate combination with the high growth rate of NTP in the Russian economy. The new technological structure emerging from the new achievements of scientific and technological progress involves the harmonization of the pace of scientific and technological development, combined with an adequate improvement in the quality of life support for citizens performing such achievements. Owing to this fact formation of new quality of the housing and communal services (HCS) as bases of life support of citizens becomes a prerequisite of increase in performance and intellectualization of human work. With this in mind, early recognition, prevention and elimination of risks of shadow and criminal activities in the housing and communal services system (housing and communal services) is considered as a significant mechanism to increase the effectiveness of the system of comfortable life support for citizens of the Russian Federation. The existing lag in the development of a high-quality and comfortable system for providing citizens of Russia on the basis of housing and communal services, the subject of which is the provision of quality and comfortable services, influenced by numerous risks of shadow and criminal influence, becomes a condition for intensifying economic development and increasing labor productivity on this basis. The need to develop and use modern scientific and technical achievements, especially in the field of digitalization, is emphasized in order to increase the efficiency of the economic security system of housing and communal services organizations based on innovative control mechanisms - internal control, audit, compliance control, taking into account financial investigations in order to prevent and eliminate the risks of shadow and criminal activities in the housing and communal services system.

 A quadrotor is a four-rotor aircraft capable of vertical take-off and landing, hovering, forward flight, and having great maneuverability. Its platform can be made in a small size make it convenient for indoor applications as well as for outdoor uses. In model there are four input forces that are essentially the thrust provided by each propeller attached to each motor with a fixed angle. The quadrotor is basically considered an unstable system because of the aerodynamic effects; consequently, a close-loop control system is required to achieve stability and autonomy. Such system must enable the quadrotor to reach the desired attitude as fast as possible without any steady state error. In this paper, an optimal controller is designed based on a Proportional Integral Derivative (PID) control method to obtain stability in flying the quadrotor. The dynamic model of this vehicle will be also explained by using Euler-Newton method. The mechanical design was performed along with the design of the controlling algorithm. Matlab Simulink was used to test and analyze the performance of the proposed control strategy. The experimental results on the quadrotor demonstrated the effectiveness of the methodology used.
