    @) The present invention relates to a hit detection equipment, usable by a fighter and an opponent for martial arts such as taekwondo, karate or boxing, comprising a central device, a valid surface, for example a jersey and / or a helmet , and at least one empowered surface, for example a glove and / or a slipper. Said valid surface comprises at least one conductive surface and said enabled surface comprises two conductive structures isolated from one another, nested one inside the other over the whole of said enabled surface, and each connected to an electrical terminal , and configured so that contact of said enabled surface on a conductive surface creates a short circuit between the two conductive structures.
    The present invention also relates to a method of detecting a blow struck by a combatant on an adversary, for martial arts such as taekwondo, karate or boxing, each equipped with equipment according to the invention.

    Hit detection equipment
    The present invention is in the field of combat sports such as taekwondo, karate or boxing. It relates more particularly to hit detection equipment.
    The present invention relates to sports such as taekwondo, karate, boxing, but is not limited to these examples and applies to any combat sport which can benefit from stroke detection equipment. In such sports, determining the number of valid strokes made to the opponent may be a judgment criterion in determining the winner of a fight. In order for a stroke to be valid, several rules may apply depending on the sport concerned.
    The blow may have to be struck on a so-called valid surface of the opponent's body. The valid surfaces can be delimited by accessories or well delimited zones, for example a plastron or a helmet in color with taekwondo.
    Only certain well delimited surfaces can be authorized to strike a valid blow. It can be for example the end of the gloves, the fists or the feet.
    Two conditions must then be satisfied for a move to be declared valid. The first condition is contact between a surface entitled to strike and a so-called valid surface of the opponent. The second condition is sufficient intensity of the blow. A simple contact may not be enough to assign a point.
    A hit detection system must therefore take these two factors into account and be able to detect a contact, as well as the intensity of the hit.
    Finally, the blows detected must then be signaled, either directly on the combatants or on a display.
    Detection systems exist, in particular for taekwondo. In order to detect contact, some systems use a faceplate lined with Hall effect sensors capable of detecting the proximity of magnets placed in the opponent's shoes and gloves. Other systems use RFID sensors. A rigid faceplate, the interior of which is lined with piezoelectric sensors, is used to measure the intensity of the blows.
    But these systems do not provide sufficiently reliable detection. Indeed, contact by Hall effect is not always well detected, while the use of RFID chips is very uncertain. The piezoelectric sensors of the faceplate are not very reliable after repeated blows on the same surface, and inactive zones appear quickly. According to statistics from the Olympic Games, the combination of these technologies leads to detection devices which do not detect up to 30% of the hits.
    In addition, such a rigid plastron hinders the movements of the combatant by its heaviness and its rigidity.
    These systems are also very expensive, which prevents significant dissemination among the practitioners of the sports concerned. Finally, information concerning the detected blows is sent by radio waves to be displayed on a screen located near the combat area. These waves, usually sent on standardized public frequency bands, for example 430 MHz, 860 MHz, 2.4 GHz or 5.6 GHz in Europe, are easily scrambled, further reducing the efficiency of the detection system.
    In addition, some martial arts have rules relating to touch discrimination. In karate for example, a valid move results in the impossibility of a valid opposing move during a specific time interval. The lack of stability of radio waves makes it difficult to apply this type of rule correctly with existing detection systems.
    Document JP2000042162 proposes a device for detecting blows comprising a plastron or a helmet provided with two electrodes, and a glove or a sock provided with a conductive surface. When the glove hits the faceplate, the conductive surface comes into contact with the electrodes and causes a short circuit which is detected. The two electrodes are arranged in the form of nested combs, so that the blow can be detected over the entire surface of the plastron or helmet. Deformable protruding elements can be arranged between the two electrodes. A blow must then be struck hard enough to deform the protruding elements and cause the short circuit, and the shots of too weak intensity are not detected. Detection information is transmitted by radio to be displayed on a screen.
    However, with such a solution, the equipment indifferently detects the blows struck by the opponent and the blows struck by the combatant himself. Furthermore, the plastron is always rigid and hinders the movements of the combatant.
    The document WO2010041304 proposes a similar hit detection equipment comprising a pair of electrodes on the surface which carries the blow, as well as on the surface which receives it. It has similar drawbacks.
    The object of the present invention is to at least partially overcome these drawbacks. To this end, it offers equipment for detecting blows, usable by a fighter and an opponent for martial arts such as taekwondo, karate or boxing, comprising a central device, a valid surface, for example a jersey and / or a helmet. , and at least one empowered surface, for example a glove and / or a slipper. This hit detection equipment is particular in that said valid surface comprises at least one conductive surface and in that said enabled surface comprises two conductive structures isolated from each other, nested one inside the other on the 'set of said enabled surface, and each connected to an electrical terminal, and configured so that contact of said enabled surface on a conductive surface creates a short circuit between the two conductive structures.
    Thanks to these provisions, reliable detection of blows can be obtained by means of simple, inexpensive and light detection equipment, which makes it more comfortable and more practical for sports.
    According to other characteristics:
    said central apparatus may comprise a transmitter of signals able to be transmitted between a combatant and his adversary by means of the contact between said authorized surface of said combatant and said conductive surface of said adversary. Thus, the hit detection information can be exchanged in a simple and reliable manner between the hit detection equipment of the combatant and his opponent, without vulnerability to jamming, said signals can be low frequency signals, typically of the order 100 kHz, which allows transfer by contact, said conductive structures can be arranged in the form of two combs or two spirals, nested one inside the other, these simple embodiments making it possible to detect a blow on all of the surfaces enabled by short circuit between the conductive structures, said conductive surface may include woven or knitted conductive wires, in particular conductive wires made of silver-coated polyamide, or of stainless steel, which makes it possible to obtain efficient conductive surfaces, in appearance and comfort equivalent to the textiles usually used for practicing sports t, the hit detection equipment can further comprise at least one shock sensor, preferably an accelerometer, making it possible to measure the impact of the hits and for example to dissociate the shots of insufficient intensity from the valid shots, the stroke detection equipment may further comprise a gyroscope, capable of detecting a rotation of 180 °, this making it possible in certain sports to detect special strokes, for example kicks in rotation at taekwondo, stroke detection equipment may further comprise at least one visual transmitter, such as a LED, capable of receiving an ignition order coming from said central apparatus, this making it possible to display in real time on the combatants the information of shots given and / or received, a plurality of transmitters capable of distinguishing different types of shots; these provisions allow the referees to count the strokes reliably without having to rely on a transmission of information between the detection equipment and a point counting system located outside the combat area.
    The present invention also relates to a method of detecting a blow struck by a fighter on an opponent, for martial arts such as taekwondo, karate or boxing, each equipped with equipment according to one of the preceding claims, comprising the steps following:
    establishment of a contact between an authorized surface of said combatant and a valid surface of said opponent, detection of a short circuit between the two conductive structures of said authorized surface, creation at the level of the equipment of said combatant of a characteristic low frequency signal suddenly, sending, during said contact, said low frequency signal to the opponent's central unit, by means of contact between the authorized area of said fighter and the valid area of said opponent, sending an order if necessary ignition to visual transmitters such as LEDs of the opponent's equipment.
    Thanks to these provisions, reliable detection of blows can be obtained by means of simple, inexpensive and light detection equipment, which makes it more comfortable and more practical for sports. In addition, the signaling of the blows provided by visual means can allow reliable counting of points without having to rely on a transmission of information between the detection equipment and a point counting system located outside the combat area.
    According to other characteristics:
    said method may further comprise at the level of the opponent's equipment at the time of reception of a signal, and depending on the nature of the received signal, neutralization of the creation of signals for a predetermined duration, this allowing to apply stroke discrimination in the sports covered by such rules, that is to say not to count strokes given within a certain time interval after a stroke received.
    The present invention will be better understood on reading the detailed description which follows, with reference to the appended figures in which:
    Figure 1 is a schematic view of a taekwondo fighter, equipped with hit detection equipment according to the invention.
    Figure 2 is a schematic view of a fighter practicing boxing, provided with equipment for detecting blows according to the invention.
    FIG. 3 is a view of a detail of the boot of FIG. 1, according to a first embodiment of the invention.
    FIG. 4 is a view of a detail of the boot of FIG. 1, according to a second embodiment of the invention.
    Figure 5 is a top view of the glove of FIG. 2, according to a first embodiment of the invention.
    FIG. 6 is a side view of the glove of FIG. 5.
    Figure 7 is a schematic view of a hit detected with the hit detection equipment according to the invention.
    Figure 8 is a schematic view of the communication between a central unit and a receiver according to the invention.
    The hit detection equipment according to the invention, as illustrated in FIGS. 1 to 8, is intended to be worn by a fighter practicing a martial art such as for example taekwondo, karate or boxing. The detection equipment comprises valid surfaces, for example a jersey 1 and / or a helmet 2 provided with a conductive surface 3 as a valid surface, a glove 4 and / or a liner 5 provided with two conductive structures 6, and a central unit 7.
    The conductive structures 6 are nested one inside the other over the whole of the authorized surface 8 of the glove 4 and / or of the liner 5. The authorized surface 8 is the set of surfaces authorized to strike according to the rules of the sport practiced. The empowered surface 8 is not necessarily limited to gloves 4 and slippers 5. If, for example, the knee or the elbow was authorized to strike, then the knee, respectively the elbow, would also be equipped with two conductive structures 6. The structures conductive 6 can for example be arranged in the form of nested combs, as illustrated in FIG. 3, or in the form of overlapping spirals, as illustrated in FIG. 4. Other arrangements allowing the nesting of the two conductive structures 6 on all of the authorized surfaces 8 are possible without departing from the scope of the present invention. The two conductive structures 6 are isolated from each other, so that direct contact between them is impossible. On the other hand, if the two conductive structures 6 touch the same conductive body, this establishes a short circuit between them, which can be detected by the central apparatus 7.
    The conductive structures 6 may consist of conductive wires, made for example from silver or stainless steel. These conductive threads can be embroidered on the surface of the glove 4, the liner 5 or any other authorized surface.
    8.
    The conductive surface 3 can extend over all of the surfaces on which a blow is valid according to the rules of the sport practiced, for example the helmet 2 and / or the jersey 1. The distribution of the conductive surfaces 3 on the fighter n is not necessarily limited to the helmet 2 and to the jersey 1. The conductive surface 3 can be produced by conductive textiles, for example a woven fabric with lines at regular intervals in warp and / or weft, made of polyamide coated with silver , or stainless steel wire. It is also possible to produce the conductive surface 3 by knitting produced with conductive wires. The conductive surfaces 3 can also be covered with a conductive material or molded from conductive rubber. Such an embodiment may in particular be suitable for a helmet 2 made of a rigid material. In particular, provision may be made to make a helmet 2 molded from polyurethane, then to mold it with a thin layer of conductive rubber.
    The conductive surface 3 can be connected by wire to the central apparatus 7, for example by a simple electric wire terminated by a crocodile type socket, in order to transmit to it information received for example on the occasion of a knock .
    As shown in Figs. 5 and 6, each conductive structure 6 of a nested pair of conductive structures 6 of an empowered surface 8 is connected to an electrical terminal 9. During contact between two nested conductive structures 6 and a conductive surface 3, the electrical terminals 9 are therefore short-circuited. To do this, the distance between the conductive structures 6 must be small enough that a blow from an enabled surface 8 on a valid surface inevitably causes a short circuit, while ensuring that the two conductive structures 6 are well insulated from each other. .
    The two electrical terminals 9 are part of an end sensor 10, for example a foot end sensor or a glove end sensor. The end sensor 10 can be connected by wire to the central unit 7 so as to be supplied with electrical energy, and exchange information with said central unit 7.
    The central unit 7 can be attached to the back of the jersey 1. The end sensor 10 can include a wired interface for connection to the central unit
    7. The end sensor can also include an easily removable mechanical and electrical attachment to the authorized surface 8. This attachment can for example be a conductive Velcro (registered trademark) type attachment. It can thus be two fasteners of this type, materializing the electrical terminals 9. This arrangement makes it possible to easily remove the gloves 4 and / or slippers 5 at the end of a fight, without these being always connected. to the end sensor 10. In this embodiment, prior to a fight, the preparation of the fighters is simplified and can include the following steps:
    putting on gloves 4 and / or slippers 5 and / or other equipment comprising empowered surfaces, fixing the central apparatus 7 and the various electrical circuits on the combatants, connection of the empowered surfaces 8 to the corresponding electrical circuits at the level of the sensors end 10.
    The end sensor 10 continuously monitors the state of the short circuit between the two electrical terminals 9. When a short circuit is detected at an authorized surface 8, the end sensor 10 sends a signal, preferably a low frequency signal, directly from said enabled surface 8 to the valid touched surface of the opponent. In a preferred embodiment of the invention, said signal has a frequency between 50 and 300 kHz, typically of the order of 100 kHz. The signal is then transmitted using the wire connecting the conductive surface 3 to the central unit 7, finally being detected by the central unit 7.
    In a preferred embodiment of the invention, the hit detection equipment comprises a shock sensor 14, which can be placed at the level of the forearm and / or the heel, and capable of determining the intensity of a stroke. The shock sensor can be an accelerometer, and can be connected to the end sensor 10. When a short-circuit contact is detected between the electrical terminals 9, the shock sensor makes it possible to determine whether the intensity of the move is sufficient for the move to be valid. The transmitted signal can then have a different frequency depending on whether the move is valid or not.
    It can also be provided that the detection of the contact by short-circuit of an enabled surface, as well as the information of the intensity of the blow, are transmitted to the central apparatus 7. This then determines the type of blow struck. : for example a kick, if the contact detection information by short circuit comes from an authorized surface of a liner 5, of sufficient or insufficient intensity according to the value measured by the shock sensor. Depending on the type of hit, the central unit 7 determines the frequency of the signal to be transmitted. This signal is transmitted during the contact of the hit, directly to the valid surface of the opponent, from where it is transmitted to the central unit 7 of the opponent.
    The hit detection equipment can also include a gyroscope, capable of detecting a rotation of for example 180 ° or 360 °. Such an arrangement can be used in certain sports, for example in taekwondo additional points are awarded for a rotating kick. The information transmitted by the signal, in particular the choice of its frequency, to the opponent's central unit 7 may then include these additional details required for the calculation of the points.
    The signal sent by the conductive structures 6 to the opponent's central unit 7 can then transport different information, distinguished for example by the use of different frequencies. The opponent’s central unit 7 can be informed of a valid move, of an insufficient intensity move, of a special move bringing in more points according to the data of the gyroscope. The opponent's central unit 7 can also be informed if the kick is a kick or a punch. He can himself determine which area of the body he has been worn on, for example on the head or on the chest, depending on the authorized area from which the information reaches him.
    As illustrated in fig. 8, the hit detection equipment can also include a visual transmitter 11, consisting for example of one or more LEDs. The visual transmitter 11 can for example be placed on the helmet 2 and / or the combatant's outfit, and connected by wire to the central unit 7. When the central unit 7 is informed of a hit received, it can control to the visual transmitter 11 associated with the valid surface having received the blow, a certain display. One can imagine that the central unit 7 controls the visual transmitter 11 a different display, for example by activating LEDs of different colors, upon detection of a contact of insufficient intensity. The display can also ίο differentiate between kicks and punches, and special moves such as a rotating kick. We can predict that if the blow was received at helmet 2, it is the led of helmet 2 that lights up, whereas if the blow was carried at chest level, it is an led at of the breast which lights up; depending on the importance of the location of the shot, and its precision, the conductive surfaces 3 can be subdivided to detect the location of the shots with more or less precision. This can be used for counting points if a regulation so stipulates, but also for training aid, by indicating to the combatant that he is more vulnerable in certain areas, and thus encouraging him to train his defense in this area.
    As illustrated in fig. 8, the information relating to the blows received can also be sent by the central unit 7 to a screen 12 outside the combat era, for example by sending a radio wave. Screen 12 may be visible to the referees and the public and allow them to follow the development of the score. In the event of a radio problem, the presence of the visual transmitter 11 ensures that the shots are counted correctly by the referees.
    The hit detection equipment makes it possible to implement a detection process comprising the following steps:
    blow struck by a combatant to his adversary, by contact of an authorized surface of said combatant and of a valid surface of said adversary short circuit between the two conductive structures 6 of said authorized surface of said combatant, for example a glove 4 or a shoe 5, by contact with the conductive surface 3 of a valid surface of the opponent's equipment, creation at the level of said combatant, for example in his central apparatus 7, of a low frequency signal characteristic of the blow carried, sending of said low frequency signal to the central apparatus 7 of the opponent, via the combatant's authorized surface towards the valid surface of the opponent during contact, sending of an order if necessary ignition to a visual transmitter 11 such as LEDs arranged on said fighter.
    As illustrated in fig. 8, the hit detection equipment may also include a display 13 making it possible to display on each fighter, the points that he has acquired. This allows an additional verification of the score at the end of the fight.
    The central device can store the recorded data for use with a view to targeted training. We can for example learn from these data that the fighter is more effective with the right foot, or with the left fist, or more vulnerable in certain areas, and therefore provide targeted training to reduce weaknesses and / or accentuate strong points.
    The power supply necessary for the operation of the blow detection equipment can be included in the central unit 7. For example, a rechargeable lithium-ion battery can be placed there.
    The invention allows discrimination of keys in real time. Indeed, the central unit 7 can centralize at all times the information of blows received and delivered, and order not to detect the blows struck in a precise time interval after having received a blow. It suffices to neutralize the creation of signals in a time interval of predetermined duration after reception of a signal from the opponent, indicating a hit received of sufficient intensity.
    The sending of signals by contact, allows a reliable transmission of information and a precise application of the rules of discrimination of keys present in certain martial arts.
    Since the impact detection surfaces and in particular the conductive surface 3 u jersey 1 can be made of textile materials, the invention makes it possible to prevent combatants from having to wear a plastron lined with sensors. Such a plastron is heavy, rigid and expensive. Traditional outfits can be used as long as they are made at least partly of conductive materials, with the possible addition of protections under the outfit.
    Although the above description is based on particular embodiments, it is in no way limitative of the scope of the invention, and modifications can be made, in particular by substitution of technical equivalents or by any combination other than any or part of the characteristics developed above.
