Description

field of technology The technical solution relates to the area of safety and protection of persons, in particular an electronic textile for detecting penetration by a projectile from a firearm or a cold weapon, and an assembly comprising this electronic textile. The current state of the art When performing duties in police and military units, it is necessary to protect individuals from being struck by firearms or edged weapons. Furthermore, in cases of inadequate protection from being struck, rapid identification of the point of entry is essential to provide the affected person with the fastest possible treatment. To save lives, therefore, the quickest possible identification of the point of entry and subsequent treatment are necessary. However, under certain circumstances during duty, it is difficult for the treating person to visually assess the point of entry, particularly the vital functions. To protect against hits from firearms and edged weapons, bulletproof vests or protective suits are available that cover the upper body and are made of robust materials. Their purpose is to protect vital organs from bullets and shrapnel, and to a certain extent, they also offer protection against edged weapons attacks. These protective suits are made of Kevlar, an aramid fiber known for its high strength and low elongation. However, the disadvantage of such solutions is that they only provide protection for vital organs, without allowing for the identification of affected body parts outside and beneath the protective clothing. However, there are no available techniques or articles of clothing for detecting the penetration of a projectile from a firearm or edged weapon. The objective of this technical solution is to eliminate this deficiency and provide a means of detecting, either once or repeatedly, the penetration of a projectile from a firearm or edged weapon, thereby accelerating the treatment process for the affected individual. This solution should be suitable not only for application on the surface of any clothing but also for use inside buildings or facilities. Furthermore, the solution should be cost-effective and easy to manufacture. Nature of the technical solution The task at hand is solved using electronic textiles to detect penetrations, particularly those caused by projectiles from firearms or edged weapons. The key technical solution is that the electronic textile has at least one detection zone containing at least one detection loop. The detection loop comprises at least two parallel, electrically conductive tracks formed from conductive hybrid threads spaced 1 to 5 mm apart. These conductive hybrid threads are sewn or woven into the electronic textile, creating the electrically conductive tracks. The detection loop covers the entire area of the detection zone and is equipped with connection contacts located at the edge or outside the detection zone. This solution enables the single or repeated detection of the point of entry of a projectile from a firearm or edged weapon, thereby expediting the treatment process for the affected individual. Furthermore, such a solution is easy and inexpensive to produce and can be used not only on the surface of any clothing, but also on building envelopes or various devices such as drones. For the purpose of describing this technical solution, the term "conductive hybrid threads" refers to the conductive hybrid threads described in utility model CZ 28603, according to which the conductive hybrid thread consists of a metal fiber with a diameter of 0.01 to 0.05 mm and a polymer fiber with a fineness of 4 to 18 tex, these fibers being twisted together. The metal fiber consists of metal from the group consisting of silver-plated copper, brass, or bronze. In a favorable design, the detection zone comprises two detection loops, with the electrically conductive paths of the first and second detection loops running parallel to each other and connected at one end. This solution enables the detection of multiple injuries, and the arrangement of the electrically conductive paths also ensures the determination of the approximate size of the wound after impact by their filling of the detection zone. In a favorable embodiment, the conductive hybrid threads are sewn, braided or woven in during the manufacture of the textile, preferably in a square, rectangular, circular, ladder-shaped, curved or comb-shaped arrangement and/or a combination thereof. tion is formed from it. The arrangement of the conductive hybrid threads is chosen so that they lie as close together as possible by sewing, braiding or weaving, thus covering the largest surface area of the electronic textile. For the purpose of describing this technical solution, the term "square, rectangular, circular arrangement" refers to an arrangement of two or more parallel conductive hybrid threads running along the entire circumference of the detection zone from its edges to its center, with the ends of the conductive hybrid
