    [0001] The invention relates to an identification device provided with a radio frequency transponder, for example of RFID type (or "Radio-identification" or "Radio-identification" or "Radio-identification" or "Radio-identification" or "Radio-identification" or "Radio-identification" Frequency Identification "in English) and / or NFC (or" Near Field Communication "or" Near Field Communication "in English) in the form of a ring. The invention can be implemented in all areas requiring identification, or a password to unlock the operation of a system, secure access controls, such as but not limited to, the automobile , home automation, for example for the opening of doors, IT, and the field of banking transactions. In the automotive field, developments in automation have equipped vehicles with a starting device by radio-identification. Such a device comprises an active transponder periodically emitting an electromagnetic field for communicating remotely with a corresponding radio reader located in the vehicle. For reasons of ease and space, the starting device comprises a housing containing the transponder, such as an RFID RF chip, a micro-antenna, and a power source. The presence of this energy source, generally taking the form of a battery, has several disadvantages, particularly related to the discharge and an oxidation phenomenon of the battery in the case where the housing is not configured. waterproof way. Furthermore, the document KR101255928 proposes a wireless radio device in the form of a ring to overcome a device type key or housing. However, this device tends to inadvertently trigger or unlock the associated system without control of the wearer. The invention aims to effectively overcome this disadvantage by providing an identification device comprising an annular body incorporating at least one radio frequency transponder adapted to emit an electromagnetic field carrying identification information, characterized in that said device identification comprises a masking device adapted to selectively allow or block propagation of said magnetic field emitted by said radio frequency transponder. The invention thus makes it possible to activate or deactivate the identification device according to the will of the wearer. This eliminates the risk of inadvertent triggering of the item to be controlled. According to one embodiment, said masking device comprises at least one ring 5 sliding in rotation with respect to said annular body, said sliding ring comprising a passage zone of the field is able to be moved between a first angular position in which the zone passing the field is located at least partly opposite said radio frequency transponder so as to allow the propagation of said electromagnetic field and a second angular position in which said passage zone is angularly offset relative to said radio frequency transponder so as to block the propagation of said electromagnetic field. In one embodiment, said field passage zone is made of a non-magnetic material. [0009] In one embodiment, said field-passing zone is constituted by an open window made in said sliding ring. In one embodiment, said identification device comprises notches adapted to provide information to the carrier relating to its activation state. In one embodiment, said identification device incorporates a biometric reading sensor. In one embodiment, said masking device is of electronic type and is able to control a power up of said transponder. The invention also relates to an assembly comprising an identification device and a corresponding radio frequency reader, characterized in that said identification device is powered by a magnetic field emitted by said radio frequency reader. According to one embodiment, said radio frequency reader is a resonant antenna having a higher resonance frequency of 5 to 20% with respect to a frequency of said electromagnetic field. In one embodiment, said radio frequency reader is integrated in a door handle. In one embodiment, said radiofrequency reader is placed inside or outside a vehicle. According to one embodiment, said identification device is able to act on a configuration of a vehicle such as locking, unlocking, energizing, preheating, starting, and / or setting of a vehicle. A driving position The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These figures are given for illustrative but not limiting of the invention. Figure 1 is an exploded perspective view of the identification device 10 according to the present invention; [0020] FIG. 2 is a front view of a transponder used with the identification device according to the present invention; FIGS. 3a and 3b are perspective views of the identification device of FIG. 1 respectively in a first position corresponding to an activated state and in a second position corresponding to a deactivated state; Figure 4 is a side view illustrating a second embodiment of the identification device according to the present invention; Figure 5 is a block diagram of the different interactions of the identification device according to the present invention with elements of its environment; Figure 6 is a sectional view of the annular body incorporating the transponder according to the present invention; Figures 7a to 7d are respectively side, top, rear and front views of a vehicle equipped with a radio reader to interact with the identification device according to the present invention. Identical, similar or similar elements retain the same reference from one figure to the next. Figure 1 shows an identification device 1 comprising an annular body 2 incorporating a transponder 3 adapted to emit an electromagnetic field 9 carrying 3036213 4 identifying information for communication with a corresponding radio player 15. Alternatively, several transponders 3 can be integrated in the annular body 2 to allow identification by different types of radio readers 15. In addition, a sliding ring 11 is rotatable relative to the annular body 2 about an axis. X. This axis X is common to the body 2 and to the sliding ring 11. The sliding ring 11, which comprises a field passage zone 12, is able to be displaced angularly between a first position, called the activation position. , in which the zone of passage of the field 12 is located at least partially opposite said transponder 3 so as to allow the propagation of the electromagnetic field 9 and 10 a second position, called the deactivation position, in which the field passage zone 12 is shifted angularly with respect to the transponder 3 so as to block the propagation of the electromagnetic field 9. In other words, in the activation position shown in FIG. e 3a, the field-passing zone 12 overlaps at least part of the transponder 3 integrated in the body 2. The electromagnetic field 9 emitted by the transponder 3 is then clear of any obstacle, so that the identification device 1 can communicate with a corresponding radio reader 15. In the deactivation position shown in Figure 3b, the transponder 3 is hidden by the sliding ring 11 made of a magnetic material. In this way, the electromagnetic field 9 emitted by the transponder 3 is blocked, which makes it possible to interrupt any communication with the radio reader 15. The zone 12 allowing the passage of the electromagnetic field 9 towards the outside of the ring may be constituted by an open window 13 having dimensions corresponding to those of the transponder 3. The window 13 passes right through the wall 25 of the sliding ring 11 and may have for example a rectangular, square, oval, or any other form adapted to the configuration of the identification device 1. Alternatively, the field-passing zone 12 corresponds to a portion of the ring 11 made of a material allowing the passage of the magnetic field, such as non-magnetic materials such as the plastic, a polymer resin or even glass. [0032] Notches between the body 2 and the sliding ring 11 may be provided to indicate to the wearer the angular position of activation or deactivation of the sliding ring 11. In another mode embodiment, the masking device is of electronic type. Non-restrictively, the masking device may then be in the form of a switch controlling the powering of the transponder 3 according to the will of the carrier of the identification device 1. The switch can move from a position 5 activation device in which the power supply of the transponder 3 by the radio reader 15 is authorized, to a deactivation position in which the power supply of the transponder 3 by the radio reader 15 is not authorized. The passage from one position to another of the switch may for example be controlled by the displacement of the sliding ring 11 relative to the annular body 2. Of course, any other equivalent means may be implemented to activate and deactivate the power supply of the transponder 3. In another embodiment illustrated in FIG. 4, the masking device is in the form of a flap 16 rotatable about a Y axis substantially parallel to the axis X. The flap 16 is movable between an activation position 15 in which the flap 16 is spaced relative to the body 2 (see position shown in broken lines) and a deactivation position in which the flap 16 covers the transponder 3. Thus, in the activation position, the flap 16 allows the propagation of the electromagnetic field 9 emitted by the transponder 3, so that the latter can communicate with the radio reader 15. In the deactivated position The shutter 16 blocks the electromagnetic field 9 and any communication with the radio reader 15. The transponder 3, for example of the RFID and / or NFC type, may be molded in a sealed manner in any plastic or metal object passing through the field. 9. The transponder 3 is advantageously in the form of a passive tag shown in FIG. 2 comprising a chip 7 of the RFID or NFC type 25 associated with an antenna 8 which captures the energy of a magnetic field emitted by a reader. 15. The transponder 3 therefore does not require a battery to operate. The transponder 3 emits an electromagnetic field 9 on predetermined frequencies. The choice of the communication frequency depends on the penetration depth of a magnetic radiation in the materials that can hold or cover the transponder 3. The detection distance of the transponder 3 by the radio reader 15 is of the order of a few centimeters, for example between 2 and 15 cm and preferably of the order of 4 cm. In an exemplary embodiment, the frequency of the electromagnetic field 9 is advantageously selected in a low frequency range of between 125 and 135 kHz, thus enabling a detection distance adapted to applications in the automotive or automotive field. home automation in particular. In another exemplary embodiment, the frequency of the electromagnetic field 9 is of the order of 13.56 MHz. This high frequency allows a shorter detection distance to ensure secure communications, such as communications in the field of banking transactions. Of course, the frequency range can be adapted depending on the application and the desired detection distance. In an exemplary embodiment illustrated in FIG. 6, the body 2 is an annular structure made of alloy of steel and titanium. The transponder 3 is placed on a layer of reflective material 4 whose characteristics will make it possible to modulate the detection distance. This reflective material 4 may for example be a material derived from aluminum. In addition, a protective layer 5 is overmolded on the transponder 3.
    [0002] For finishing, a layer of varnish 6 covers the protective layer 5. The protective layers 5 and varnish 6 are transparent to the emission field 9 emitted by the transponder 3. In a variant, the protective layers 5 and of varnish 6 are confused. Of course, the thickness and the choice of the material can be adapted according to the application. In addition, as shown in FIG. 4, a biometric reading sensor 14 makes it possible to read a fingerprint of a carrier of the device 1. The biometric reading sensor 14 is preferably positioned on the internal surface of the device. 2. Thus, the reading of the fingerprint is performed when the wearer passes the identification device 1 along his finger. The reading is then performed only once during the passage of the identification device 1 at the level of the fingerprint of the wearer. As soon as the identification device 1 is removed, the biometric identification is claimed. This biometric identification acts as a switch enabling the transponder 3 and therefore the propagation of the electromagnetic field 9 to be activated or deactivated directly. The biometric reading sensor 14 is powered by electromagnetic induction, or by any other appropriate means such as a source. integrated in the identification device 1. In the case of an automotive application, the transponder 3 may for example communicate with N directional radio readers 15 (N being an integer greater than or equal to 3036213 7 1) located in a vehicle 20. This communication is intended to allow rights and / or services to be opened for a carrier of the identification device 1. For this purpose, each radio frequency reader 15 includes a reception antenna for a transponder 3. antenna is preferably in the form of a coil 5 of rectangular section associated with a capacitor to constitute a ntenne resonant. Such an antenna concentrates its energy in certain directions and is intended to operate optimally at a certain resonant frequency and for accurate adaptation resistance. To make this antenna less sensitive to surrounding metal elements, its resonant frequency and its matching resistance have been adapted. In an exemplary embodiment, a coil of about 3 mH with a matching resistance of the order of 250 to 500 ohms offers the radio player 15 a signal of optimal quality. The resonance frequency is not necessarily fixed to the frequency of the electromagnetic field 9 emitted by the transponder 3. Indeed, a better reception 15 of the electromagnetic field 9 is obtained when the resonant frequency of the antenna of the radio reader 15 is 5 to 20% higher than the frequency of the electromagnetic field 9. The power supply of the radio reader 15 is provided by a battery 21 present in the vehicle 20 generally delivering a voltage of 12 volts. This type of radio reader 15 is placed in such a way as to optimize the reading of the electromagnetic field 9 emitted by the transponder 3. As an example visible in FIGS. 7a to 7d, four radio readers 15 (N = 4) each controlling a different function, are installed on a vehicle 20. The radio readers 15 were in this case integrated in a door handle 151, in a trunk handle 152, in a speed knob 25 153, and in the vicinity of A safety belt buckle 154. For a motorcycle, the radio readers 15 can be integrated on the fuel tank or in the acceleration handle. It will be noted in this case that the electromagnetic field 9 is slightly attenuated by a glove-type textile interposed between the transponder 3 and the radio reader 15. The radio readers 15 are in the form of a solenoid about 400 turns 30 with an inductance of the order of 3mH. The form, their adaptation resistance, their resonance frequency, and the number N of radio reader 15 are not limiting. Thus, when the wearer grasps the handle of a door of the vehicle 20 to open with his hand carrying the identification device 1 in an activated state, the device 1 3036213 8 undergoes an electromagnetic induction on the part of the radio player 151 integrated in the handle. The induced current, of the order of 101..1A and 5V, is sufficient to supply the transponder 3 which returns to the antenna of the radio reader 151 a high security identification code preprogrammed during manufacture and not modifiable. This identification code is then filtered, demodulated and analyzed by a microcontroller located in an electronic circuit 18 located near the radio reader 153. The identification device 1 is then recognized, the vehicle 20 is unlocked instantaneously and an adaptation of the driving position is carried out quickly, in a time of about 4 to 6 seconds. To better control the communication between the identification device 1 and 10 the radio players 15, a switch 17 controls the power of the electronic circuit 18, protected by a housing, allowing a radio player 15 to emit a strong magnetic field. In an exemplary embodiment, the housing protecting the electronic circuit 18 is approximately 11 cm long, 6 cm wide and 4 cm thick and is made of aluminum. This housing is closed by four security screws. In this way, the electronic circuit 18 is protected against both theft and foreign electromagnetic waves. Preferably, an ignition switch 17 controlling the preheating, starting and stopping of the vehicle engine 20, is associated with a starter radio reader 153 located in the gear knob. The switch 17 can be placed in the passenger compartment, within reach of the driver such as on the side of the gear knob, near the parking brake, or on the dashboard. Such a switch 17 can be paralleled to the conventional starter system by connecting preheat and start control wires to relevant motor actuators or by connecting them to a key switch 23. when the driver installed in the driving position presses the switch 17 controlling the ignition and when placing his hand equipped with the identification device 1 near the radio reader 153 start, the vehicle 20 starts. The vehicle 20 remains in operating condition until the switch 17 is pressed again. To this end, the radio reader 153 controlling the start detects the identification device 1 and when the carrier presses the switch 17, the associated reader 153 switches to a de-energized state. In this state, the reader 153 no longer needs identification to keep the engine running. Pressing the switch 17 again will switch off the engine of the vehicle 20 and simultaneously turn on the radio reader 153. The radio reader 153 will then request the high security identification code of the identification device 1. The N readers generally switch from one live state to another depending on the state of lock or unlocking of the device. vehicle 20, with the exception of the radio control 5 153 controlling the start and the reader 152 placed in the trunk handle. Indeed, whatever the locking or unlocking of the vehicle 20, the reader 152 can actuate cylinders opening the trunk automatically. Of course, each radio reader 15 can also be associated with a switch 17. As shown in FIG. 5, the identification device 1 can act on a central locking and unlocking control 22, on a key switch. 23, on various accessories 24, on a driver's seat 25, on mirrors 26, and on an interface 27 controlling an on-board computer 28, a GPS 29, and a vehicle configuration. These various commands are made via actuators controlling, for example, the position and orientation of the mirrors 26, the position, the height, the inclination of the driver's seat 25 and its head support, the position of the steering wheel. Via a bus connected to an interface 27 adapted to the communication protocol of the vehicle 20, the device 1 can also act on the visual of a computer screen 28, the radio station listened to, the voice of the GPS 29, the height of the suspensions as well as their hardness, the hardness of the power steering, the electronic help for driving, the driving style, the power of the vehicle 20 and any motor clamping intended for young drivers. Preferably, the identification device 1 is synchronized with the absolute time clock sent by the GPS. Thus, when a carrier is authenticated as being a driver of a vehicle 20, he finds each of the settings, accessories 24, and driving typing, as he had 25 programmed. Each additional setting that the driver will make during his session will be recorded. The invention thus allows to find the driving position exactly as left in the last use, and to clamp the engine for young drivers. According to the vehicle 20 and the need, the identification device 1 can also be connected to the Internet network via a cellular data connection, by Wifi or Bluetooth, this allowing interaction with the base of the device. data of the vehicle 20 containing a number of its characteristics, for example and without limitation: the identification profiles, the configuration of the driving position, the driving history, the scheduling of driving, the consumption fuel, the mileage taken or to be made, the route programmed in GPS 29, and the actual route In addition, several identification devices 1 can be synchronized to the same vehicle 20. The registration of the identification devices 1, the driving position, and the engine configuration is carried out by operating a specific command. of the electronic circuit 18 interacting with the microcontroller. Thus, each carrier using the vehicle 20 can be identified. The entire driving position, as well as the characteristics of the engine can be adapted, hours of use, as well as history can be recorded. The specific control of the electronic circuit 18 may be in the form of a switch, a keypad code, or remote access type Internet. The use of such an identification device 1 thus allows a simplified and secure identification. In addition, this device 1 does not require a battery does not risk to oxidize. More advantageously, the masking device 11, 16 allows the wearer to operate his identification device 1 according to his will, which avoids any untimely operation without control of the wearer.
