Description

[0001] The present invention relates to a vest adapter wearable by an emergency responder, comprising an infrastructure for connecting a plurality of modules. Furthermore, the present invention relates to a system comprising a vest adapter and a number of modules connected to the infrastructure of the vest adapter. Furthermore, the present invention relates to an emergency responder-wearable assembly comprising a protective vest for the emergency responder and a vest adapter, or a system comprising a vest adapter and connected modules.

[0002] Conventional protective vests for operational forces, such as soldiers, are known which have an integrated, i.e. permanently connected infrastructure for coupling a plurality of modules, such as communication modules and energy modules.

[0003] US 2018 / 249133 A1 discloses a personal tactical system comprising a ballistically wearable garment, a pouch with one or more batteries contained therein, an electronic processor, a communication device, and at least one camera. The camera is built into or removably attachable to the wearable garment, the pouch is removably attachable to the wearable garment, and the one or more batteries are operable to power the camera and the communication device. The processor executes image recognition software operable to identify approaching objects and alert the user. Multiple personal tactical systems are operable to form an ad hoc network to exchange images and other information for determining object direction, location, and movement.

[0004] Furthermore, US 2014 / 101831 A1 discloses a vest assembly for use by a user. The vest assembly includes a vest body, a plurality of communication components disposed in the vest body, an antenna disposed in the vest body or otherwise connected to the vest body, a rechargeable power supply, and a thermoelectric converter assembly for converting body heat energy into electrical energy to charge the power supply and / or power the communication components. The antenna is in electrical communication with at least one of the communication components.

[0005] Against this background, one object of the present invention is to improve the coupling of a plurality of modules to a personnel protected by a protective vest. This object is achieved with the vest adapter according to claim 1.

[0006] According to a first aspect, a vest adapter wearable by an emergency worker for connecting a plurality of modules is proposed. The vest adapter can be detachably coupled to a protective vest of the emergency worker. The vest adapter has at least a first partial region for wearing in the area of ​​the chest of the emergency worker and a second partial region for wearing in the area of ​​the back of the emergency worker. In particular, the vest adapter has a third partial region for wearing in the area of ​​the shoulders of the emergency worker. The vest adapter is formed by a first material layer, a second material layer, and an infrastructure arranged between the first and second material layers for coupling the modules, wherein the infrastructure has a plurality N1 of units of a wired interface type connected via cables and a plurality N2 of units of a first wireless interface type connected via cables.

[0007] The cables are, in particular, ribbon cables. The emergency responder is, for example, a soldier. Other examples of emergency responders include firefighters, police officers, Federal Agency for Technical Relief (THW), and the like.

[0008] Examples of the modules to be connected include a communication module, an interface module, a USB module, a connector module for connecting external devices and / or sensors, an energy module, for example comprising an accumulator, an effector, a display device, an operating device, a GPS receiver, an electronic system, such as a vehicle system, and / or sensors.

[0009] Examples of sensors include a gyroscope, an accelerometer, a pedometer, an altimeter, a light sensor, a microphone, ambient noise cancellation, and / or a compass.

[0010] With a wired interface type, e.g. USB (Universal Serial Bus), data and power transmission are exclusively wired, i.e. exclusively wired data and power transmission internal to the infrastructure and exclusively wired data and power transmission external to the infrastructure, ie in particular to and from the modules.

[0011] With a wireless interface type, e.g., Bluetooth, the data transmission and / or power transmission occurs wirelessly, at least over a portion of the route. In particular, with the wireless interface type, data transmission occurs exclusively wirelessly externally to the infrastructure and exclusively wired internally.

[0012] For security reasons, especially to prevent interference and eavesdropping, data transmission within the infrastructure is therefore exclusively wired. This increases security.

[0013] The vest adapter with the infrastructure for connecting the modules can be detachably coupled to the protective vest of the emergency worker, i.e., detachably attached. In other words, the vest adapter can be attached to the protective vest, particularly above, inside, or below the protective vest, and this attachment can be removed again. Examples of fastening devices for attaching the vest adapter to the protective vest include clips, clamp connections, plug connections, zippers, and / or hook-and-loop fasteners.

[0014] The proposed vest adapter can be coupled with different vests of the same or different types. This provides a significant advantage over protective vests with integrated infrastructure for connecting modules. If, for example, a cable in the infrastructure breaks in the field, for example, during a battle, the affected soldier can simply replace the vest adapter with a replacement, advantageously keeping their protective vest on.

[0015] With a conventional protective vest with integrated infrastructure, a soldier would have to replace the entire vest if a cable were to break. Consequently, the flexible applicability of this vest adapter also increases the safety of soldiers. Furthermore, cost savings are advantageous, as a spare safety vest with integrated infrastructure does not have to be kept on hand for each soldier.

[0016] A further advantage is that the emergency worker can continue to wear their accepted protective vest, often an individualized protective vest.

[0017] The two layers of material and the infrastructure arranged between them are constructed in a sandwich construction.

[0018] The infrastructure can also be referred to as a connection facility or coupling facility.

[0019] According to one embodiment, the infrastructure comprises a plurality N3 of cable-connected units of a second wireless interface type and a plurality N4 of cable-connected units of a third wireless interface type. N1, N2, N3, and N4 are, in particular, natural numbers.

[0020] For example, the wired interface type is USB (Universal Serial Bus), the first wireless interface type is WiFi (Wireless Fidelity), the second wireless interface type is Bluetooth, and the third wireless interface type is NFC (Near Field Communication).

[0021] According to a further embodiment, the respective unit of the wired interface type is designed as an electrical and mechanical connection unit, in particular as a connection plug or connection socket.

[0022] According to a further embodiment, the respective unit of the wireless interface types is designed as an antenna or as an electrical and mechanical connection unit, in particular as a connection plug or connection socket.

[0023] According to a further embodiment, two units of the same interface type are connected by means of a point-to-point connection formed by one of the cables. One of the two units, which is designed as a connection unit, is arranged in a connection arrangement of the infrastructure.

[0024] For example, if the infrastructure of the vest adapter has four USB ports for connecting a respective module via USB, two NFC antennas for a respective NFC communication, one WiFi antenna for a WiFi communication and one Bluetooth antenna for a Bluetooth communication, then the infrastructure has a total of eight point-to-point connections via cable and seven connection units (4 x USB, 1 x WiFi, 1 x Bluetooth, 1 x NFC) within the connection arrangement of the infrastructure.

[0025] For example, the first section for wearing on the chest of the emergency worker comprises two USB ports and an NFC antenna. The second section for wearing on the back of the emergency worker contains, for example, the connection arrangement, two USB ports, a WiFi antenna, a Bluetooth antenna and an NFC antenna. The second section for wearing on the back can extend down to the coccyx area of ​​the emergency worker, with two of the aforementioned ports, e.g. USB and NFC, then being located in this area of ​​the coccyx. Different people have relatively small variance in the coccyx area, so the NFC antenna located there can be used by different people to communicate with a permanently installed receiving unit, e.g. in a vehicle, a seat or a chair.

[0026] According to a further embodiment, the connection arrangement of the infrastructure can be connected to a corresponding connection arrangement of an interface module. The interface module comprises a respective control unit for each of the interface types of the infrastructure and at least one connection unit, in particular a connector and / or an antenna.

[0027] The control unit can be implemented in hardware and / or software. In a hardware implementation, the control unit can be embodied as a device or as part of a device, for example, as a computer or a microprocessor. In a software implementation, the control unit can be embodied as a computer program product, as a function, as a routine, as part of a program code, or as an executable object.

[0028] A computer program product, such as a computer program means, can be provided or delivered, for example, as a storage medium, such as a memory card, USB stick, CD-ROM, DVD, or in the form of a downloadable file from a server in a network. This can be done, for example, in a wireless communications network by transmitting a corresponding file with the computer program product or the computer program means.

[0029] According to a further embodiment, the wired interface type is configured as a USB. Its infrastructure units are configured as USB connection units. At least one of the USB connection units is connectable to a USB module. The USB module comprises a USB hub having a USB controller and a plurality of USB connection units for forming a cascaded star network with the USB connection units of the vest adapter's infrastructure.

[0030] The USB connection unit can also be referred to as a USB port or USB connection and is designed as a USB plug or USB socket.

[0031] By using the USB module and creating a cascaded star network, the number of USB ports on the vest adapter is scalable. Thus, depending on the application, the vest adapter can provide an adjustable number of USB ports, e.g., 4, 8, or 12.

[0032] According to a further embodiment, the respective material layer is formed from a fabric, in particular a textile, a plastic material, a fiber composite material, or a metal material. For a number of connecting units, the material layer has a respective feedthrough for connecting one of the modules.

[0033] The feedthrough is particularly suitable for leading the respective connection, for example a USB connection, from the infrastructure to the outside, where a corresponding USB connector of an external module can be plugged in.

[0034] According to a further embodiment, the material layer has a receiving device in the area of ​​the respective feedthrough for receiving the connectable module. The receiving device is designed, in particular, as a pocket.

[0035] The corresponding module can be plugged into the receiving device and, for example, the USB socket of the infrastructure can be connected to the USB plug of the module.

[0036] According to a further embodiment, the infrastructure of the vest adapter is configured to communicatively couple a contactless smart card worn in a garment of the emergency worker to an electronic system for transmitting cryptographic material and / or data provided by means of the cryptographic material.

[0037] For example, the item of clothing is a soldier's identification tag (dog tag chain) worn on a chain, which has, in particular, an integrated contactless smart card. The electronic system is, in particular, a vehicle system, for example, a wheeled armored vehicle. The following example can illustrate the functionality of the vest adapter in question: When the soldier enters the vehicle with his identification tag on his neck and wearing a protective vest with the vest adapter attached, he can identify and / or authenticate himself to the vehicle system using the data stored on the smart card. For this purpose, the NFC interface discussed above can be used, for example.If one of the two NFC antennas is arranged in the first sub-area for wearing in the chest area and the second NFC antenna is arranged in the second sub-area for wearing in the coccyx area, the first NFC antenna can capture the data from the smart card, transmit it via the NFC connection unit in the connection arrangement to the second NFC antenna in the coccyx area, and from there, the second NFC antenna can transmit this data to a receiving unit of the vehicle system, which is arranged in the vehicle seat. Such communication can also be bidirectional, in particular.

[0038] According to a second aspect, a system is proposed which comprises a vest adapter according to the first aspect or one of the embodiments of the first aspect and a number of modules connected to the infrastructure of the vest adapter.

[0039] According to a further development, the number of connected modules comprises an interface module which has a respective control unit and at least one connection unit, in particular a connection plug, and / or an antenna for each of the interface types of the infrastructure of the vest adapter.

[0040] According to a further development, the wired interface type is configured as a USB, and its units of the vest adapter infrastructure are configured as USB connection units. The number of connected modules includes a USB module, which comprises a USB hub having a USB controller and a plurality of USB connection units for forming a cascaded star network with the USB connection units of the vest adapter infrastructure.

[0041] According to a third aspect, an arrangement wearable by an emergency worker is proposed, comprising a protective vest for the emergency worker and a vest adapter according to the first aspect or one of the embodiments of the first aspect, wherein the vest adapter and the protective vest are detachably coupled, or a system according to the second aspect or one of the developments of the second aspect, wherein the system and the protective vest are detachably coupled.

[0042] Further possible implementations of the invention also include combinations of features or embodiments described above or below with respect to the exemplary embodiments not explicitly mentioned. In this case, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

[0048] The vest adapter 10 can be detachably coupled to a protective vest (not shown) of the emergency worker. This means that the vest adapter 10 can be detachably attached to the protective vest.

[0049] The vest adapter 10 to Fig. 1 has a first section T1 for wearing on the chest of the emergency worker, a second section T2 for wearing on the back of the emergency worker, and a third section T3 for wearing on the shoulders of the emergency worker. The vest adapter 10 can be worn in or on the protective vest.

[0050] As in Fig. 2 As shown, the vest adapter 10 has a first material layer 11, a second material layer 12 and an infrastructure 13 arranged between the first material layer 11 and the second material layer 12 for coupling the modules 21, 22 (according to Fig. 1 ).

[0051] In the example of Fig. 1 The infrastructure 13 of the vest adapter 10 has four USB ports 31-34 for connecting a respective module via USB, two NFC antennas 61-62 for a respective NFC communication, a WiFi antenna 41 for a WiFi communication and a Bluetooth antenna 51 (BT, Bluetooth) for a Bluetooth communication.

[0052] For example, the first section T1 for wearing in the chest area of ​​the emergency worker includes two USB ports 31, 32 and an NFC antenna 61.

[0053] In the second sub-area T2 for wearing in the area of ​​the emergency worker's back, for example, the connection arrangement 70, two USB ports 33, 34, a WiFi antenna 41, a Bluetooth antenna 51 and an NFC antenna 62 are provided.

[0054] The second sub-area T2 for wearing in the back area can be extended to the coccyx area of ​​the emergency worker, in which case, for example, the USB port 34 and the NFC antenna 62 are arranged in this area of ​​the coccyx. It should be emphasized that different people have a relatively small variance in the coccyx area, so that the NFC antenna 62 arranged there can be used by different people for communication with a permanently installed receiving unit 24 (see Fig. 7 ) of a vehicle system. Details will be provided with reference to the Fig. 7 described.

[0055] Continue with reference to Fig. 1 , the connection arrangement 70 of the infrastructure 13 can be connected to a corresponding connection arrangement 101 of the interface module 100 (see Fig. 3 ). The interface module 100 has a respective control unit 102-105 for each of the interfaces within the connection arrangement 70 and a number of connection units, here the USB ports 111-113.

[0056] In addition, the interface module 100 includes the Fig. 3 an audio unit 120, a control unit 130, and a power unit 140. The audio unit 120 can, for example, comprise a microphone and / or a loudspeaker. The control unit 130 comprises, for example, a microprocessor. The power unit 140, in particular, has a number of accumulators.

[0057] As the Fig. 1 shows, the infrastructure 13 comprises a number of USB ports 31-34. The USB module 200 of the Fig. 4 The USB module 200 of the Fig. 4 has a USB hub 201 comprising a USB controller 202 and a number of USB ports 203-206. Without limiting the generality, the USB module 200 of the Fig. 4 Four USB ports 203-206. A larger or smaller number of USB ports is also possible.

[0058] The USB module 200 with USB controller 202 and USB ports 203-206 is thus configured to form a cascaded star network with the USB connection units 31-38 of the infrastructure 13 of the vest adapter 10.

[0059] Furthermore, the communication module 300 of the Fig. 5 The communication module 300 of the Fig. 5 has a USB controller 301 and two USB ports 302, 303.

The mechanical part of the connector module 400 is modularly replaceable and can also be used for connecting cables.

[0061] As the Fig. 2 shows, the infrastructure 13 is arranged between the first material layer 11 and the second material layer 12. The first material layer 11, the second material layer 12 and the infrastructure 13 are constructed in particular in the manner of a sandwich construction. The respective material layer 11, 12 is formed, for example, from a fabric, such as a textile, from a plastic material, a fiber composite material or a metal material. For a number of the connecting units, in the example of the Fig. 2 the USB ports 31, 33, is a respective feedthrough 15, 16 for connecting one of the modules in one of the material layers, in the example of the Fig. 2 in the first material layer 11.

[0062] The material layer 11 can have a receiving device for receiving the connectable module in the area of ​​the respective feedthrough 15, 16. Such a receiving device (not shown) is designed, for example, as a pocket.

[0063] Furthermore, the Fig. 7 a schematic block diagram of another embodiment of a system 1 with a portable vest adapter 10 for an emergency worker. The vest adapter 10 corresponds to the one described with reference to the Fig. 1 bis 6 explained vest adapter 10. The Fig. 7 differs from the Fig. 1 in the coupled modules 23 and 24, instead of modules 21 and 22 in Fig. 1 . In the example of Fig. 7 Module 23 is a soldier's identification tag (dog tag chain) that contains a contactless smart card SC. Module 24 is a receiver unit of a vehicle system, for example, a wheeled armored vehicle.

[0064] When the soldier enters the vehicle wearing his identification tag 23 and a protective vest with the attached vest adapter 10, he can identify and / or authenticate himself to the vehicle using the data stored on the smart card SC. The NFC antenna 61 of the first sub-area T1 receives the data from the smart card SC and transmits it via the NFC unit 63 of the connection arrangement 70 to the NFC antenna 62 arranged in the coccyx region.

[0065] The NFC antenna 62 can then transmit the data to the receiving unit 24 of the vehicle system to perform the identification and / or authentication of the soldier. Such communication can also be bidirectional. The receiving unit 24 is installed, for example, in a vehicle seat of the vehicle. LIST OF REFERENCE SYMBOLS
