It is able to measure, store and simultaneously process 16 parameters of the human body’s movement independently, but also in relation to the movement of the vehicle. The partial information that appears after the processing has finished on a numeric computer, a PC, will allow us to assume the way in which these occupants will behave in all the phases of a car accident: before, during, when coming out of it and after the collision, as well as to design new constructive measures to ensure that there is a non-lethal space within the occupant-interior elements-vehicle frame. Key-Words: - forensics, measuring system, DSD, BMC, Xsens 1 Introduction The information given by the measurement and data purchasing technical systems after the experimental research was performed make the processing of the said data easy and lead to a series of practical considerations such as: choosing the correct measurement method, adapting and connecting the machines that make up the said technical system, ensuring the conditions for normal functioning by isolating them from exterior factors, the presence of a simple user interface. The safety of the occupant who is driving the car depends on a significant number of geometric- constructive factors and the ones present in the driver’s seat and their technical state, respectively. Among these factors, it can be observed the geometry of the char, the spatial configuration of the board, the passive safety systems, the elastic characteristics of the material used on the bottom and upper part of the chair, the pressurizing characteristics of the airbag systems, etc. At the same time, the safety of the occupant is influenced mainly by the type and the manner in which the collision takes place, by the type of safety belt that exists in the car, by the correlation between the position of the driver with the location where the main force of the collision was applied, as well as the rigidity of the vehicle. One can say that the safety of the vehicles in general and the safety of the occupants to be more exact are very complex issues that determine the position and the state of the vehicle, as well as the movements of its occupants. Because of this, these issues are given special attention. This field does not focus on theoretical and experimental researches, but the purpose is to identify adequate constructive solutions that would lead to an improvement of the safety of the passengers when they come in contact with sharp bodies or interior elements that can cause damage. 2 Research Methodology Starting from these considerations, the present work presents a few aspects regarding experimental research focused on the safety of the driver when the driver is a pregnant woman. For this, it was developed a technically complex measuring system that registers and stores the movement parameters of the victim present in a vehicle, as well as those of the vehicle when it collides with another obstacle. The main scheme of this technical system is illustrated in figure 1 and it is made up of the following measurement and registering machines: T 1 DSD PicDAQ measurement and storing unit that is specialized in acquiring data in digital form, which contains a triaxial accelerometer [1, 5]. One can notice that the information received using the DSD PicDAQ, XSens units are saved and archived on an SD memory card of 8GB in order to process and interpret them later on with the help of a PC computer that contains special programs for analysis International Journal of Environmental Science http://www.iaras.org/iaras/journals/ijes Crauciuc Daniel, Sifft Michael, Thierheimer Walter Wilhelm, Alexandru Cătălin, Thierheimer Alexandru ISSN: 2367-8941 91 Volume 3, 2018
