Abstract
Description
field of technology
[0001] 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
[0002] 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.
[0003] To protect against hits from firearms and edged weapons, bulletproof vests or protective suits are available. These 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 stretch. However, the disadvantage of such solutions is that they only provide protection for vital organs, without allowing access to vulnerable areas of the body both outside and beneath the protective clothing.
[0004] However, there are no available techniques or articles of clothing for detecting the penetration of a projectile from a firearm or edged weapon.
[0005] 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
[0006] The task at hand is solved using electronic textiles to detect penetration, particularly 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. The conductive hybrid threads are sewn or woven into the electronic textile, thus forming 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.Such a solution enables the one-time or repeated detection of the point of entry of a projectile from a firearm or edged weapon, thus accelerating the treatment process for the affected person. Furthermore, such a solution is simple and inexpensive to manufacture and can be used not only on the surface of any clothing, but also on building envelopes or various devices such as drones.
[0007] 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.
[0008] 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.
[0009] In a favorable embodiment, the conductive hybrid threads are sewn, braided, or woven into the textile during its manufacture, preferably forming a square, rectangular, circular, ladder-shaped, curved, or comb-shaped arrangement and / or a combination thereof. The arrangement of the conductive hybrid threads is chosen such that they lie as close together as possible by sewing, braiding, or weaving, thus covering the largest possible surface area of the electronic textile.
[0010] 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 threads located at the edge or outside the detection zone and forming electrically conductive tracks with connecting contacts. The appropriate arrangement is used depending on the shape of the detection zone.
[0011] For the purpose of describing this technical solution, the term "ladder-like arrangement" refers to an arrangement of longitudinally running straight conductive hybrid threads, arranged parallel to each other at a distance of 1 to 5 mm and connected by two perpendicular straight conductive hybrid threads, forming electrically conductive tracks with connecting contacts.
[0012] For the purpose of describing this technical solution, the term "curved arrangement" refers to an arrangement of conductive hybrid threads that are arranged curvilinearly parallel to each other at a distance of 1 to 5 mm and are connected to a perpendicular straight conductive hybrid thread, forming electrically conductive tracks with connecting contacts.
[0013] For the purpose of describing this technical solution, the term "comb-shaped arrangement" refers to an arrangement of conductive hybrid threads that run parallel to each other, forming the shape of the teeth of a comb.
[0014] In another cost-effective version, the electronic textile comprises at least two or more detection zones. Such a solution enables rapid and frequent detection in different areas of the garment with precise localization thanks to the arrangement of the detection zones.
[0015] In another advantageous embodiment, the electronic textile further comprises a waterproof film based on polyurethane, polyethylene, polyester, or Teflon, which covers at least one detection zone. Such a solution prevents water penetration and deterioration of the detection zone if the conductive traces cause a short circuit due to moisture.
[0016] The task is further solved by a module for detecting the penetration of clothing by a projectile from a firearm or edged weapon. The essence of the technical solution lies in the fact that the garment contains an electronic textile with the aforementioned technical characteristics and an evaluation unit located outside the detection zone and connected to the electronic textile's terminals. The evaluation unit is typically available to the person wearing the garment containing the electronic textile, enabling them to quickly assess the penetration themselves, or it may be available to the first responder who arrives at the injured person's location.
[0017] In a cost-effective design, the evaluation device consists of a unit for measuring the change in resistance of the detection zone or the detection loop. Such a design is simple, easy to manufacture, and exhibits precise evaluation characteristics. The electrically conductive traces cease to react when a projectile from a firearm or edged weapon penetrates the electronic textile; that is, they no longer register any resistance, which is the key measurement unit of such an evaluation device.
[0018] The task is further solved by a module for detecting the penetration of a building envelope by a projectile from a firearm or edged weapon. The essence of the technical solution lies in the fact that the building envelope contains an electronic textile with the aforementioned technical characteristics and an evaluation unit located outside the detection zone and connected to the terminals. The evaluation unit is preferably a device for measuring the change in resistance of the detection loop. This solution makes it possible to transmit data from the detection zone using an evaluation unit connected to the terminals outside the detection zone. The evaluation unit is typically located at an easily accessible height within the building to allow for simple and rapid detection, where the terminals are also located.Such a solution also allows for quick and easy repair of the assembly if needed.
[0019] The stated problem is further solved by a module for detecting the penetration of a drone's outer shell by a projectile from a firearm or edged weapon. The essence of the technical solution lies in the fact that the drone's outer shell contains an electronic textile with the aforementioned technical characteristics and an evaluation unit located outside the detection zone and connected to the terminals. The evaluation unit is preferably a device for measuring the change in resistance of the detection loop. Such a solution makes it possible to transmit data from the detection zone using an evaluation unit connected to the terminals outside the detection zone. This solution is particularly advantageous for military purposes, as drones are widely used in war zones and rapid detection of drone damage is essential.It is also possible to wirelessly connect the evaluation unit to another device available to the person remotely controlling the drone.
[0020] The advantages of electronic textiles for detecting penetrations, and of assembling devices incorporating these electronic textiles according to this technical solution, lie primarily in their ability to enable the single or repeated detection of the impact point caused by a projectile from a firearm or edged weapon, thus accelerating the treatment process for the injured person. Furthermore, such a solution can be used not only on the surface of any type of clothing, but also on building envelopes or various devices such as drones. Additional advantages of the described solution include low production costs and ease of manufacturing. Explanation of the drawings

Examples of the implementation of the technical solution: Example 1
[0022] The one in Fig. The illustrated assembly for detecting the penetration of clothing by a projectile from a firearm or edged weapon consists of an electronic textile 1 with dimensions of 100 × 100 mm, which is connected to an evaluation device 6 located outside the electronic textile 1, e.g., in a pocket of the clothing or on a different part of the clothing than the part covered by the electronic textile 1. The evaluation device 6 is a device for measuring the change in resistance of the detection zone 2. In another example of the embodiment, not shown, the evaluation device 6 is a device for measuring the change in conductivity of the detection loop 3 of the detection zone 2. The Fig. The electronic textile 1 shown comprises four detection zones 2, 2', 2'', 2'''. In another example of the embodiment, not shown, the electronic textile 1 has at least one detection zone 2. If necessary, however, it is possible to implement other dimensions of the electronic textile 1 or other dimensions and connections of the individual detection zones 2, 2', 2'', 2'''. This assembly makes it possible to detect a penetration, determine the size of one or more penetrations, and locate the point of penetration.
[0023] Each detection zone 2, 2', 2'', 2''' comprises two detection loops 3, 3'. In another example of the embodiment, not shown, each detection zone 2, 2', 2'', 2''' comprises one detection loop 3. Each detection loop 3, 3' consists of two parallel, electrically conductive tracks 4, 4' formed by conductive hybrid threads. The electrically conductive tracks 4, 4' are created using embroidery techniques with VÚB as's conductive hybrid thread No. 53, which consists of 47% (4 × 5.5 tex) PESh and 53% (4 × Cu / Ag wire with a diameter of 0.03 mm). In this example, the conductive hybrid threads are arranged in a square pattern, as shown in the Fig. shown. In another, not shown, example of the implementation, the conductive hybrid threads are woven or braided into the fabric that forms the electronic textile 1.
[0024] The electrically conductive tracks 4, 4' are arranged at intervals of 3 mm. In another embodiment, not shown, the electrically conductive tracks 4, 4' are arranged at intervals from 1 to 5 mm. The electrically conductive tracks 4 of the first detection loop 3 and the electrically conductive tracks 4' of the second detection loop 3' run parallel to each other, with the detection loops 3, 3' covering the entire area of each detection zone 2, 2', 2'', 2'''. This arrangement enables high reliability in detecting penetrations from a caliber of 4.6 mm and offers the possibility of determining the caliber size and detecting multiple penetrations. Each detection zone 2, 2', 2'', 2''' is also provided with connection contacts 5, 5', which are located outside each detection zone 2, 2', 2'', 2'''.Two opposing detection zones 2, 2' and detection zones 2'', 2''' are connected to each other by the connection contacts 5, 5', which are connected to the evaluation unit. In another example of the embodiment, not shown, in the case where the electronic textile 1 comprises only one detection zone 2, this detection zone 2 is also provided with connection contacts 5, which are connected to the evaluation unit 6. The electronic textile 1 is covered on its surface with a waterproof film made of polyurethane, polyethylene, polyester, or Teflon, which covers all four detection zones 2, 2', 2'', 2''' and serves to prevent short circuits of the electrically conductive tracks 4, 4' due to contact with water. In another example of the embodiment, not shown, the waterproof film is based on polyethylene, polyester or Teflon and covers at least one detection zone 2, 2', 2'', 2'''. Example 2

Each detection loop 3, 3' includes two parallel electrically conductive tracks 4, 4' formed by conductive hybrid threads and arranged in a comb-like pattern at intervals of 3 mm. The ends of the detection loops 3, 3' are connected to each other. The connection contacts 5 are equipped with snap fasteners for attachment to the textile for connecting evaluation electronics, such as the evaluation unit 6. Example 3
[0026] An assembly for detecting the penetration of clothing by a projectile from a firearm or a cold weapon according to Example 1 is created. This assembly consists of an electronic textile 1 with dimensions of 100×100 mm, which, however, comprises only one detection zone 2 with a detection loop 3. The detection loop 3 is formed by electrically conductive tracks 4, 4' which consist of conductive hybrid threads, as in the Fig. The conductive hybrid threads are arranged such that the parallel conductive hybrid threads forming the electrically conductive tracks 4, 4' are located on opposite sides of the detection zone 2, where they are provided with connecting contacts 5, 5'. Between these electrically conductive tracks 4, 4' are parallel conductive hybrid threads running perpendicular to the two outermost conductive hybrid threads and spaced 2 mm apart. The detection zone 2 thus produced is not coated on its surface with a waterproof film based on polyurethane, polyethylene, polyester, or Teflon. Example 4

In another example of the arrangement, the electronic textile 1 is arranged only in selected parts of the surface of the building envelope. The evaluation unit 6 is located at a height not exceeding the building height of 2 m to allow for easy evaluation and handling of the evaluation unit 6, as well as for any necessary maintenance or repair. The connection contacts 5 extend from the individual detection zones 2 to the evaluation unit 6. Example 7
