(19) The same reference numbers will be used whenever possible to designate the same or similar elements, throughout the remainder of the description.

(20) The magnets used in embodiments of the invention described specifically herein are preferably based on neodymium, iron boron with a compressed density of 7.3 to 7.5 g/cm3, the coating of the magnet making it conductive, possibly being obtained from an alloy based on nickel, zinc or tin, and/or copper.

(21) One example of an advantageous method for making the magnetic materials based on rare earths for use with the invention is also and for example as follows.

(22) The different raw materials for the alloy are firstly mixed with high precision, under a vacuum or inert gas.

(23) For example, components are mixed according to the following preparations by mass of neodymium iron boron with 25% to 31% of neodymium, 2 to 3% of a mixture of Cu, Al, Co, Ga, Nb and Zz, 0.8% to 1.1% of boron (Neodymium 38 to 52) and the remainder being iron or neodymium 40 in one preferred embodiment composed of the order of 28.8% of neodymium, 1% of boron, 4% of Ce, Al, Cu, Co+others and the remainder iron.

(24) The basic material can be obtained by melting constituents or by calcio thermal reduction, for example at about 1300° C. from an NdFe fluoride and iron chloride FeCl3 compound (NdF3+Ca+FeC13−<(NdFe)+CaCIF+CaFe2).

(25) The raw material particles are ground until they satisfy very precise tolerances (grains of the order of 1 micron).

(26) The products are then stamped, imposing a powerful magnetic field on them to orient the metallic particles.

(27) Finally, the elements are sintered in special vacuum furnaces at 1050° C., or under argon.

(28) After fast cooling, the temperature is brought back to high temperatures (600 to 900° C.) before fast quenching to terminate the cycle.

(29) Finishings are then made using spark erosion machines or machines fitted with diamond tools because the final product is very hard.

(30) Materials that can be used include particularly Samarium Cobalt (SmCo5, SmCol7) and other types of neodymium iron boron (Nd2F14B), that are very efficient magnetic materials based on rare earths.

(31) The final product made of neodymium iron boron can be made conducting while preventing the oxidation process for example by galvanizing it simply (Ni, Sn or Zn) or triply (Ni+Cu+Ni) (Sn+Cu+Sn) or (Zn+Cu+Zn) or advantageously Ni+Ni+Au or Ni+Au.

(32) In the case of nickel, gold galvanization, thicknesses of nickel and gold equal to the order of 0.01 mm and 0.001 mm respectively can be used.

(33) The magnets can advantageously be covered one by one with a protection layer, also obtained by nickel/copper or nickel/epoxy galvanization, or any other galvanization that will prevent rusting of the magnets.

(34) These higher quality magnetic materials are used at locations at which a very high magnetic force is required and occupy only one fifth of the space occupied by hard ferrite magnets with the same magnetic power.

(35) They are then cut to the required dimensions, for example 3×3×2 mm and fixed by gluing them to each other in configurations that will be described below with reference to the following figures.

(36) FIG. 1 shows a device 1 comprising a support 2 in the form of a hood made of a stretch fabric woven removably onto a headset 3 and for example attached with hooks stitched onto the fabric.

(37) The support enables electrical connection 4, 4′, 4″ . . . , keeping them in contact and the attachment of several accessories 5, 6, 7, 8, 9 and 10 to each other (see also FIG. 2).

(38) For example, accessory 7 is a rechargeable battery (connection 4) supplying power to accessories 5 (weather—pressure, humidity sensors, etc.), 6 (connector with a rucksack or a breast plate), 8 (GPS), 9 (visual-camera) and 10 (electromagnetic wave transmission module with an external server—not shown).

(39) In the particular embodiment described herein, the connection between the base plates is made with copper or aluminum tape strips glued on the lower fabric, between two fabric layers one of which acts as a support.

(40) The upper fabric is impermeable and protects the magnetic strips and the upper part of the first magnetic elements from dust and humidity, without preventing electromagnetic contacts between them, for example as explained in the embodiments described below with reference to FIGS. 11 to 14.

(41) Advantageously, portions of insulating tape are provided at appropriate locations in order to prevent bad contacts between strips.

(42) The location of accessories can be different and/or can be at specific positions.

(43) For example, the battery can be located at the back of the headset, its weight then being chosen so as to compensate the weight of infrared goggles on the front of the headset.

(44) But it would also be possible to use a module to house a standby battery (or secondary battery) or a battery to supply power to the modules continuously if the main battery behind the headset is replaced.

(45) FIG. 2 shows an example of connections between the first magnetic elements, for example as shown on FIG. 3.

(46) More precisely, FIG. 3 shows a first magnetic element comprising a support 11 on which magnets 12, 13 are fixed with alternating polarities, in other words a first polarity, for example positive, alternating with a second negative polarity, by gluing.

(47) In this embodiment in which a six-wire electrical connection is required, in which one wire is connected to two nearby magnets, in particular a coating is provided for the magnet concerned (in this case part of the magnets 12) among these magnets, by a specifically conducting material (Nickel, Cu, etc.), the magnets being electrically insulated from each other in a manner known in itself to prevent short circuits, for example by a plastic film and/or a wall (see below).

(48) The contact or solder of the wire onto the magnet, for the connection with another device, can for example be made by cold soldering and/or using a conducting glue.

(49) The wire can also be a conducting strip in the form of a tongue (for example 1 or 2 mm wide) made of copper or aluminum placed on the side or face of the magnet (attachment tip 14), or with copper tape placed on the active face of the magnet.

(50) FIG. 3A shows an example of a reversible connection for a USB type connector.

(51) A USB connector comprises four wires (Red=5 volts (Vbus), White=data−, Green=data+, Black=ground) and a second ground=braid wound around the four wires, namely five contacts.

(52) The five contacts are essential for transmission of images.

(53) In this embodiment and in order to make the USB contact reversible, the positive magnets denoted A, C, E, F, G, I and K of a first magnetic element of a first accessory as described with reference to FIG. 3A, are then connected to the negative magnets B, D, F, H, J, L of a first magnetic element of a second accessory.

(54) For example, the wires could thus be connected as follows:

(55) Groups: Ground: EFGH, Red: AL, Black: CJ, Green: DI, White: BK.

(56) FIG. 4 shows a portion of a device comprising another embodiment of the first magnetic elements 21 according to the invention.

(57) This embodiment does not show the fabrics and/or protections of the external electrical contact parts between first magnetic elements and second magnetic elements (with their orifices enabling contact).

(58) The device comprises for example a base S, for example rectangular and made of insulating plastic material, fixed on the support 22, for example a first sheet 23 made of impermeable stretch fabric known in itself, with glue made impermeable by silicone 24 around the bottom of the base.

(59) The electrical wires 25 or small strips of sticky copper 26 are placed (fixed) on the first sheet 23, and are covered by a second sheet made of impermeable stretch fabric 27 (in dashed lines on FIG. 4) fixed on the first sheet in a manner known in itself.

(60) In this embodiment, third and fourth impermeable sheets (therefore not shown) protect the external surfaces of the first and second magnetic elements sealed by silicone, and conducting glue on the pads themselves as described below.

(61) The base plate S comprises a receptacle 28 arranged to contain a block 29 comprising six magnets in the form of parallelepiped shaped pellets (for example 3×3×2 mm), with alternating polarity, namely three positive magnets 30, 31, 32 and three negative magnets 33, 34 and 35 insulated from each other by walls 36 made for example from PLA.

(62) Each magnet and/or magnetic element is inserted in a layer of elastic glue (not shown) resistant to washing, itself fixed to the support. They are all, or for some of them (according to the needs of the electrical connector), connected to the electrical wires 25 in a manner known in itself.

(63) The walls 36 are sufficiently thick to prevent short circuits.

(64) The magnets are fixed on a flexible or rigid horizontal rectangular plastic plate 37 and comprise a screen 38 (thin iron film) on their faces on the side of the support 22, that will enable a mirror effect (arrow F), for example the screen itself being fixed on a plastic sheet (for example PU) 39 to make the attachment to the base plate S.

(65) They comprise a protection layer or fabric on their faces on the side opposite the support, providing protection against humidity and making the assembly impermeable to water and dust, however the conducting parts are free, for example in a manner known in itself and/or as described with reference to FIGS. 11 and 14.

(66) The portion of a device on FIG. 4 also includes an accessory 40 comprising a box fitted with a removable lid 41 and a lower part 42, for example with a hexagonal shape, comprising a lower plate 43 fitted with an edge 44, arranged to hold an electronic device 45 (GPS, remote control system, movement sensor (accelerometer) etc.) connected as described above (by soldering and/or gluing with conducting glue) to the magnets in the block 46 of a second magnetic element, namely three positive magnets 33′, 34′, 35′ arranged to cooperate with three negative magnets 33, 34, 35 of the first magnetic element, and three negative magnets 31′, 32′ and 33′ arranged to cooperate with the three positive magnets 31, 32, 33 facing the magnets of the first magnetic element, but also in this case impermeable to external humidity.

(67) The block 46 is also inserted in the lower face of the plate 43 and of the assembly 45 with which it is therefore connected as described above.

(68) The external face of the block 46 is flush with the rest of the lower face.

(69) Advantageously, the clip-fitting means (not shown), known to an expert in the subject, are provided between the plate 43 of the second magnetic element and the first magnetic element 21.

(70) The first magnetic element of FIG. 4 is shown more precisely on FIGS. 5 and 5A to 5C.

(71) FIG. 6 shows another assembly of the first and second magnetic elements (50 and 51).

(72) In this case, the blocks 52, 53 are formed from five positive magnets 54, 54′ and five negative magnets 55, 55′ arranged alternately and offset facing each other between the two opposite elements.

(73) A click-fitting lid of the housing 56 on the support 57 of the electronic device 58 is provided to enable a good manual grip of the accessory to fix-release the first magnetic element, particularly by a simple lateral action (arrow 59) to separate the magnets on the first and second magnetic elements. The polarities that attract each other then suddenly repel each other.

(74) FIG. 7 shows a double stretch fabric 60 acting as a support for firstly the first magnetic elements and the connection strips or wires, and secondly impermeable protection of the same elements (but enabling electrical contacts between the two).

(75) More precisely, three first magnetic elements 61, 62 and 63, are represented in this figure, arranged to cooperate with three accessories 64, 65, 66, the first elements 61 and 62 being connected to each other by corkscrew type wires 67, 68, etc. (not all represented) enabling elasticity, and the first elements 62 and 63 also connected to each other by wires 69, 70, 71 in the same manner.

(76) The accessory 66 is connected through a strip 72, for example that may also be elastic and connected to a second magnetic element 73 and/or another type of connector such as a USB connector that will for example be connected to an external device 74 on the rucksack 75 (see FIGS. 8 and 8A) of the user 76.

(77) The user 76 also wears a jacket 77 comprising a sheet 78 (see also FIG. 9) of connected wires 79, 79′, 79″ so as to identify a damaged zone 80 in a manner known in itself, for matricial electrical detection.

(78) Cut wires 79 provide information about the matricial location by a change in the resistivity of the wires concerned.

(79) More precisely, functioning of the fabric can detect an impact or a cut, for example based on the functional principal described below.

(80) The fabric comprises a multitude of sets each formed from a wire and/or a line (for example conducting ink) and a given resistance value R, placed vertically and horizontally (diagonal wires could also be added).

(81) A first set comprises a thin tinned (or twisted) copper wire 79 and a resistor, for example with a value of between 1 and 10000 Ohms.

(82) A second set is identical except that in this case the value of the resistor is equal to 2 to 20000 Ohms.

(83) The sets are permanently powered by a battery.

(84) A relay is provided (not shown) with two positions: make and break is provided. The make position is powered by the battery, and the break position occurs if the wire is broken. Therefore, if the wire is cut, it provides information that the wire of the first, or second, etc. resistor is broken.

(85) The vertical wires are ordinates and the horizontal wires are abscissas.

(86) As shown on FIG. 9, the impact point 80 can be localized by vertical wire number 3 (79) and horizontal wire number 5 (79′).

(87) The information transmitted will be 3V/5H, therefore the person who receives the information will know the impact point 80 precisely and can deduce information from it.

(88) One example use of a device according to the embodiment of the invention described specifically below is represented with reference to FIG. 10.

(89) The battery accessory 7 is fixed on the headset 3, to power the different modules of the other accessories 5 (GPS module), 10 (Transmission module), 9 (visual module/camera), and 6 (connection module with the external device).

(90) The connection module 6 can be used to retransmit information from the breast plate 81 (for example allowing ballistic detection 82) and detection of information derived from other elements, for example providing information about the content of the pocket 83 of the jacket worn by the user.

(91) The transmission modules 10, are used to dialogue with an external server 84 (command post), itself interacting with other devices 85 (drones, vehicles, etc.) that will be able to perform operations 86 (for example deliveries of missing parts) to locations detected and positioned by the GPS modules 5.

(92) We will now describe operation of the device with reference to FIGS. 1, 8, 9 and 10.

(93) A user who decides to use the device according to the embodiment of the invention described more particularly herein will fit the support/hood on their headset.

(94) They will then connect the accessories that they have decided to use to the different locations of the first magnetic elements.

(95) Not all locations (in this case eight locations) are necessarily used.

(96) Placement takes place naturally, the connection direction necessarily being found by the user, the polarities naturally acting as a foolproof system.

(97) A mechanical click fit/release system can also secure the position, but the strength of the magnets is sufficient to prevent the loss of an accessory.

(98) All accessories are then connected by wire and will then be able to interact with each other depending on the required functioning, that will depend on the required application in a manner known in itself.

(99) When the user would like to disconnect, replace or change the position of an accessory, all they have to do is to push the accessory laterally on its head, the differences in polarities of the magnets, once offset slightly, will almost automatically eject the accessory due to magnetic repulsion.

(100) In the case of using a connected charger pocket (83), this informs the staff that such or such soldier no longer has ammunition. It is thus decided, automatically or not (server 84) to send a drone which will bring the soldier ammunition, or a medical kit, or food for survival, for example. It is the function of the pocket which comprises a sensor (empty/full) which will transmit information via the module situated on the headset which in this case, is important.

(101) FIG. 11 is a lateral view of a hood 90 made of stretch fabric formed from three patterns 91, 92 and 93 (see FIG. 12A to 12C) stitched to one another on their opposing lateral side edges 94, in a manner known in itself.

(102) The hood is, for example, removably attached on the headset, for example by clips.

(103) This dismountable character enables its replacement and/or its cleaning, easily.

(104) The hood comprises eleven electrical connector locations 95 with modules, each comprising orifices 96 for the passage of electrical contacts sealed through conductive glue stoppers of the type described above.

(105) The internal electrical connector system or circuit network between the first magnetic elements 97 of the type described for example in reference to FIG. 6 has been represented in FIGS. 12A to 12C, the four central orifices 98 corresponding to one same ground wire 99.

(106) In the embodiment described in this case, the other orifices 96 correspond to different red, black, green and white inputs/outputs of a USB type plug, as represented in FIG. 3A (and of which the electrical connector wires 100 to 105 connected to one another are, for example, made by screen printing with a graphite paste such as described above.

(107) FIG. 13 shows an example of an embodiment of the electrical connector by screen printing obtained with a stencil, corresponding to the central pattern 91 (reversed) such as traced (line 106) on the material 107.

(108) Each wire (which can also be formed by Scotch® Cooper) of a pattern 91, 92, 93 is connected to the corresponding wires of the pattern nearby by way of a wider strip 108 (for the wires 100), 109 (for the wires 101), 110 (for the wires 102), 111 (for the wires 103) and 112 (for the wires 105).

(109) The end of each of these strips of a pattern comes opposite the end of each strip of the other pattern, the sealed electrical connector being ensured during the cutting of edges of peripheral parts 94 of one pattern on the other.

(110) In FIGS. 14 and 15, two embodiments of the external contact part of a first magnetic element through an orifice 96 have been represented, the hood 90 in FIG. 11 showing the conduction through the fabric.

(111) More precisely, FIGS. 14 and 15 show a magnet 113 of the type described above.

(112) After piercing the fabric 114 through the orifice 96, for example of diameter of 1 to 2 mm, this is deposited on an assembly formed by a sanded, adhesive, copper film 115 (or screen-printed conductive paste lines as described above) belonging to the network such as described in reference to FIGS. 12A to 12C, for example, that is glued onto the magnet 113, by means of a glue tip 116.

(113) A conductive glue drop 117 is thus deposited in the orifice 96 that it blocks so it is sealed, opposite the magnet.

(114) It all is then and for example covered with a Teflon or resin sheet (dot-dash line 118) to obtain a smooth and elastic surface. Then, the Teflon is removed by sanding at the level of the orifices 96 to achieve a conduction with the outer face of the glue drop, which will be in contact with the module.

(115) FIG. 15 shows the case where the screen-printed alloy wire or the Scotch® Copper is situated on the other side of the magnet with respect to the fabric, opposite to FIG. 14.

(116) In this case, the electrical connector between the conductive glue drop 117 and the screen-printed alloy wire or adhesive, copper strip (Scotch® Copper) must avoid the magnet 113, for example by means of a U-shaped sheet 118, for example made of Scotch® Copper, a magnetic insulating plate 119 of the magnet with respect to the head of the user of the hood being, for example, also provided.

(117) Obviously, and also consequent to all the above, this invention is not limited to the embodiments specifically described. On the contrary, it includes all variants and particularly variants in which the support is different, for example possibly a jacket, a vest or a belt.

(118) One of the advantages of this invention is that the positions of different accessories can be swapped, and it is easy to replace them in the case of damage or wear.

(119) With the invention, it is also possible to use a fixed or removable pocket in a jacket, for example connected to the headset and that signals if it is empty or full.

(120) Advantageously, the accessories will be able to receive Braille type signals (touch) so know if it is a telephone or a camera.

(121) Also advantageously, the battery comprises two second magnetic elements arranged to cooperate with two first magnetic elements to give an even more secure attachment on the headset, for mechanical reasons related to its weight and its position.

(122) Advantageously, the articulated magnetic strips are crossed in order to split into two, the number of lines/circuits, which also enables and particularly to be able to return the modules to 180°, which for example, enables their placement by the user without being concerned about the delivery direction of the module.
