    UNIVERSAL WIRELESS TOUCHES DETECTOR FOR ESGRIMA
    SECTOR OF THE TECHNIQUE
    The present invention is related to electronic sports signaling systems, specifically for the sport of fencing.
    In the sport of fencing, the referee is the figure responsible for deciding when there has been a valid headdress of one shooter over another or, if it occurs, a double headdress. However, in a sport where speed is crucial, the referee's own expertise is often not enough to be able to determine precisely who is the winner at each point. Given this difficulty, multiple support systems have been invented to visualize headdresses in a clearer and less subjective way. Of all the systems, the most widespread in training and competitions is the electrical system by cables. Some wireless headphone detection systems have also been proposed that avoid the inconvenience of being permanently connected to a cable for shooters, and there are numerous proposals on paper, for example in the form of a patent.
    The present invention proposes a method and its realization in the form of a circuit capable of detecting fencing headpieces for the foil, sword and saber modalities, which does not require any external wired connection and that can be used as a sensor system in headdress detection units They communicate wirelessly with a central console.
    BACKGROUND OF THE INVENTION
    Conventional wire fencing detection systems are made up of an electrical installation that links each shooter's weapon with a central and common console that processes the information that arrives through the cables. Depending on the weapon mode in which the console selector is placed, a different circuit is closed for each case. Although different, the circuits

    They have in common the objective of determining which headdresses are valid depending on whether the shooter touches one or another area of the opponent's body. Usually, the cables are retained in extendable reels that regulate the portion of wire that reaches the handles to facilitate their movement on the track. However, the presence of cables inevitably implies a limitation and a nuisance for free movement. This drawback is precisely what motivates the use of wireless detection systems.
    In the case of the foil mode, only the opponent's trunk is a valid area for the headdress. The weapon and the track constitute invalid areas. Head, leg and head headdresses should be considered equally invalid although, unlike the gun and the track, they should be indicated on the console by a white light. To carry out the detection, the weapon has a normally closed push-button sensor that connects the blade of the weapon with a single conductive wire located in a small channel in the blade of the weapon. The weapon uses an electrical connector with two contacts, one connected to the mentioned wire and the other to the blade and bowl, joining the weapon to the console through the wired installation. The leaf and the bowl of the foil are permanently connected to the common mass, shared by the two handles, as is the metal track. Each shooter incorporates a vest that covers the trunk and connects to a continuous tension provided by the console through a third conductive wire. When the tip of the weapon touches a non-conductive surface, the push button on the tip opens allowing the insulated thread of the weapon to be disconnected from the blade, which is detected by the console. If the surface contacted is the adversary's vest, the tip modifies its tension equal to that of the vest, in which case the valid headdress is detected and indicated. If the surface contacted is the track or the weapon of the adversary, both connected to ground, the conductive wire is kept connected to ground and no touched is detected.
    In the case of the sword mode, the entire body of the rival, including feet and hands are valid areas for a headdress. The detector must only distinguish between the entire body of the rival, the weapon and the ground. Therefore, there are two zones, one valid and one invalid. To carry out the detection, the weapon has a normally open push-button sensor encapsulated in the tip of the weapon. When the tip is pressed against a surface, the button closes causing a short circuit between two conductive wires that the weapon carries inside a small gutter, isolated from the
    5
    10
    fifteen

    35
    weapon blade Finally, the electric sword has a connector that allows these conductive wires to be connected to the console through the wired installation, and a third contact that connects the bowl and the blade of the weapon directly to ground. This mass is shared by the two weapons of the handles and the floor of the metal track. The contact on any surface corresponding to the body of the rival drives the spring of the sensor contact and allows the passage of a signal in the form of continuous tension towards the console. In the case of targeting an invalid surface, such as the bowl or the track, which are connected to ground, the tip of the sword closes the circuit directly to ground thus avoiding the generation of a valid hit signal.
    In the saber mode, a simpler weapon is used in connection. Due to the regulatory characteristics, in this case it is necessary to distinguish, again, between two zones. A zone of valid headdress constituted by the trunk and the head of the adversary and an invalid zone formed by the rest of the surface of the body, the weapon and the track. An important difference of this weapon with respect to the sword and the foil is that the latter are pointed weapons, that is, all valid attacks are those carried out with the tip of the weapon, while the saber is a weapon of cut and valid attacks are those that are made interchangeably with the tip or with the edge of the blade. In order for the headdress signaling system to be effective, it is necessary to use a bib or vest that covers the trunk of the handles and a conductive mask. The saber has a single connector that connects the entire weapon through a cable to the console. The vest and the mask are joined by a driver and constitute a second contact towards the console. When a shooter touches the opponent's breastplate with his saber, the circuit closes. Contact with any other zone leaves the circuit open and does not cause the system to respond.
    The basic principle of operation of the cable touch detection systems is the fact that the two handles and the console form a single circuit with a common mass that makes it possible to identify the different zones. This fact and the design of weapons and special equipment have consolidated the electrical signaling system as the approved system for this sport. This basic principle of operation is, however, one of the main drawbacks when designing a wireless system that can replace or compete with the wired system. In a wireless system there is no single circuit consisting of the two weapons and the console, but three independent circuits that have

    of interacting with each other. On the other hand, it is desirable for commercial and cost interests not to modify current weapons.
    At the time of writing this patent, there are some wireless headphone detection systems on the market. The WF1 system of Favero Electronics [Fav-17] is a training system consisting of two emitters and one receiver. The receiver is integrated into the box itself where the entire system is stored and transported, and works for sword and foil, allowing the coexistence of up to twelve systems performing simultaneous fighting.
    The Hitmate Epée Hitmate Ltd system [Hit-17] is a compact training device, in this case only for the sword mode, which also consists of two transmitter modules and a receiver that signals the headdresses. It has a child variant, the Mini Hitmate system.
    The STM Wireless system [StM-17] is a system approved by the International Fencing Federation and used in world championships and Olympic games since 2001, initially for the saber mode and, subsequently, also for foil and sword. It consists of two devices for two shooters and a third signaling device. It requires the use of a conductive bracelet in the modality of a sword and a conductive shirt for the case of foil and saber, as well as adjustments tailored to the physical characteristics of the handles. It presents as remarkable performance the fact that the headdress is visualized directly in the mask of the shooter by means of a light signal.
    On the other hand, there are several proposals in the form of a patent for wireless fencing signaling systems. Delcayre's patent [Del-58] and its subsequent improvements [Del-62] [Del-63] describe wireless headphone detection systems that are complex and require multiple and delicate adjustments. The touch information is sent to the console via radio signals. Optionally, the headdresses can be displayed on the shooter itself. Another patent of the same inventor [Del-77] uses a new simplified headdress detection system based on pulse generation.
    The Harashima [Har-96] patent is based on the application of frequency signals

    different that uniquely identify each of the areas that can be touched, a fact that requires the use of multiple filters tuned to each of the possible frequencies in the headphone detection unit. Touched information is sent to the center console by radio frequency.
    The Linsay Patent [Lin-06] discloses a fencing signaling system for the various modalities. Similarly, messages about headdresses are sent by radiofrequency and oscillators are used connected to the different zones, bowl, vest and track, which are identified by a unique frequency. For each frequency there is an oscillator and a detector. It does not offer details on how the detectors work.
    Huang's patent [Hua-08] proposes a system for sword and foil. Generates and receives radio signals transmitted through a traditional sword or foil to count and display the results of the scores. When the tip of the weapon touches a surface, the button located on the tip of the weapon is closed activating the transmission of radio signals to a console in charge of displaying the scores. This patent describes a system that is not able to differentiate between valid and invalid touched. Therefore, it does not meet the basic requirement of any headdress signaling system for fencing.
    The Moncunill patent [Mon-10] presents a wireless headdress detection system for sword and saber modes that uses identical devices for both handles and compatible with conventional electric weapons.
    The Morehouse patent [Mor-14] presents an apparatus that allows fencing headdresses to be detected in all three modes and indicates which shooter has scored. The device is placed on the wrist and communicates wirelessly with a fencing console or with a computer.

    EXPLANATION OF THE INVENTION
    The present invention describes the method and its realization in the form of a circuit for the detection of headdresses in wireless signaling systems in the sport of fencing. The detector object of the present invention incorporates a mechanism that solves the problem of detecting external signals that do not use a common mass reference. Specifically, it uses the capacitive coupling that is established between the body of the two handles to close the circuit, using alternate signals. The detector generates local oscillations that, applied to the weapon blade and to the vest, if applicable, can be detected by the headpiece detection unit of the opposite. In turn, the detector incorporates a signal input sensitive to alternating signals of external origin weakly coupled to said input, a weak coupling being understood to be that which is made through a high equivalent impedance of Thevenin. The external source signal is combined with the signal

    coupled to the local oscillator to generate intermodulation products at the output of a non-linear circuit. The intermodulation product constitutes a new frequency that only appears when the aforementioned signals are present simultaneously at the input.
    The block diagram of the detector object of the present invention in its most complete version is shown in Figure 1, and consists of: a common ground terminal (1) common to all blocks, a local oscillator (2), a generator mixed signal (3), a first continuous component detector (4), an intermodulation product generator (5), a second continuous component detector (6), a first alternating component detector (7), a second detector alternating component (8), a ground connection terminal (9), an alternating signal output terminal (10), a signal input terminal (11), an alternating signal output terminal with continuous component (12 ), an output terminal of the first continuous component detector (13), an output terminal of the intermodulation product generator (14), an output terminal of the second continuous component detector (15), an output terminal of the first alternating component detector (16) and an output terminal d the second alternating component detector (17). In the modalities of sword and foil there is a certain external coupling (18) between the alternating signal output terminal (10) and the signal input terminal (11) caused by the weapon. Although not explicitly shown in the figure, the existence of a battery that acts as a power supply for the entire system is assumed.
    From now on, the output signal of a block will be considered active when there is a significant variation in its value with respect to the idle value. The output signal of the first continuous component detector (13) is activated when there is a change in the continuous component present in the signal input terminal (11). In the foil mode, this change is due to the fact that the normally closed button that joins the alternating signal output terminal (10) with the signal input terminal (11) opens. In the sword mode, the value of the continuous component is modified when the button short-circuits the signal input terminal (11) with the alternating signal output terminal with continuous component (12), whose alternating component is deactivated in this mode . In the case of a saber, the value of the continuous component in the signal input terminal (11) is not modified because it is permanently connected to the signal output terminal

    alternates (10), so, in this mode, the first continuous component detector (4) has no function and is expendable.
    The intermodulation product generator (5) is required to output (14) to provide a continuous component dependent on the amplitude of the signal coupled through the weapon from the alternating signal output terminal (10) to the output terminal. signal input (11). In this way, when the tip of the weapon touches a metal surface to which no alternating voltage has been applied, an alteration in the aforementioned coupling occurs, which in turn results in a variation of the continuous component at the exit of the intermodulation product generator (14) that can be detected by the second continuous component detector (6). This mechanism allows to detect the contact of the weapon with a metallic surface, being the most accentuated effect with large surfaces, as is the case of the track.
    When the tip of the weapon comes into contact with a metal surface subjected to an alternating voltage with respect to the local mass of the opposing shooter, such as the case of the gun bowl or vest, it is generated by capacitive coupling between the body of the two handles an alternating voltage at the signal input terminal (11) that is combined with the signal coupled from the local oscillator (2). Said combination generates a low frequency intermodulation product at the output of the intermodulation product generator circuit (5) of frequency equal to the difference in fundamental frequencies present at the input. Depending on the frequency of the intermodulation product, the output of the first alternating component detector (16) or that of the second alternating component detector (17) is activated. Based on subject to alternate voltages of frequencies conveniently chosen the different metal surfaces of the opposite handle, it is possible to distinguish those touched to said surfaces by observing the outputs of the alternating component detectors (16) (17). The detector object of the present invention is compatible with the three methods of fencing: foil, sword and saber.
    The foil mode is the most complex in terms of variety of headdresses and requires all the blocks represented in Figure 1. Figure 2 shows the corresponding scheme of the headdress detection unit (32) that the shooter incorporates as part of its equipment, which includes the detector (20) object of the present invention, a microcontroller (21) and a radio frequency transceiver (22).

    The ground connection terminal (9) is connected to the skin of the puller by means of a conductive interface (23) to increase the effective surface of said terminal and reinforce the coupling of locally generated signals to the opposite and vice versa. The alternating signal output terminal (10) is connected to the bowl (24) which in turn is connected to the gun blade (25), the signal input terminal (11) is connected to the only internal conductor ( 26) of the weapon and the alternating signal output terminal with continuous component (12) is connected to the vest (33) of the shooter. The button located on the tip of the weapon (28) is normally closed and opens when touched. The track (30) on which the combat takes place does not require the connection of an oscillator between it and the ground (31), as it happens in other headdress detection systems. In this system, a track hit (30) will activate the output of the second continuous component detector (15), a hit to the weapon will activate the output of, for example, the first alternate component detector (16), and a hit to the The opposite vest will activate the output of the second alternating component detector (17). An invalid hit to the body of the opposite shooter will not activate any of the outputs, except for that of the first continuous component detector (13). There is, therefore, a unique combination of active outputs for each possible headdress, information that can be interpreted by the microcontroller (21) to decide whether it is a valid headdress or not and to send such information via a transceiver (22 ) via radio to the central signaling console. The microcontroller (21) communicates with the central console by means of a pre-established protocol and is assigned a unique identifier that is included in the messages sent to the console. The console is responsible for indicating to the microprocessor (21) the method of fencing and to process the messages received from each of the touch detection units (32) to perform the signaling properly.
    Figure 3 shows the block diagram of the system adapted for sword fencing. The handle incorporates as part of the equipment the headdress detection unit (32), which includes the detector (20) object of the present invention, a microcontroller (21) and a radio frequency transceiver (22). The ground connection terminal (9) is also connected to the shooter's skin via a conductive interface (23), the alternating signal output terminal (10) is connected to the bowl (24) integral with the weapon blade (25), the signal input terminal (11) is connected to the first internal conductor (26) of the weapon and the signal output terminal

    alternate with continuous component (12) to the second internal connector (27). In this mode, the alternating component of the mixed signal generator (3) is deactivated, so that it provides only the continuous component. The button located on the tip of the weapon (28) is normally open and closes when touched. The microcontroller (21) and the transceiver (22) perform the functions described above for the case of the foil mode, and the use of an oscillator connected to the track (30) is also not required.
    The modality of saber is the one that implies greater simplicity. Figure 4 shows the system block diagram for this mode. The headdress detection unit (32) includes, as in the previous cases, the detector (20) object of the present invention, a microcontroller (21) and a radio frequency transceiver (22). The ground connection terminal (9) is also connected to the skin of the handle via a conductive interface (23). In this case, the alternating signal output terminal (10) and the signal input terminal (11) are connected to the bowl (24) integral with the gun blade (25). The output impedance of the local oscillator (2) must be adequate to allow significant fluctuations caused by coupled signals of external origin at the signal input terminal (11). In this mode the first continuous component detector (4) is expendable. The second continuous component detector (5) can eventually be used to detect track touches (30), the first alternate component detector (7) can be used to detect touched the weapon, and the second alternate component detector (8) is the only essential block, whose output (17) will be activated when there is a headdress to the vest (33) on the contrary, that is, when a valid headdress occurs. The microcontroller (21) and the transceiver (22) perform the functions described above for the case of foil and saber, and the use of an oscillator connected to the track (30) is also not required.
    The detector object of the present invention is characterized by being universal, in the sense that it allows distinguishing the main types of headdress that occur in each of the fencing modalities. It adapts to conventional electric weapons and the corresponding connection passages without requiring any modification. The fact of discriminating the touches through the generation of intermodulation products simplifies the processing of the signals because they are low frequency products, avoiding the need to use very selective filters. Likewise,
    5
    10
    fifteen
    twenty
    25
    30
    35
    It constitutes a robust detection mechanism, since the intermodulation product cannot be generated by the presence of local oscillations alone, but requires the combination of the local oscillation with the coupled oscillation of the opposite handle. In this sense, in the design of the detector, care must be taken that the coupling of the alternating component of the mixed signal generator to the signal input terminal is weak, and the frequency of this oscillator must be chosen appropriately to minimize the impact of the intermodulation product which is capable of generating locally. The interpretation by a microcontroller of the signals coming from the detector allows the implementation of intelligent algorithms that adapt to the fluctuations that may occur in the signals received due to the variation of the weight of the shooters, the sweating during combat or any other circumstance.
    BRIEF DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, an set of drawings is attached as an integral part of said description, where, for illustrative and non-limiting purposes, the next:
    Figure 1.- Shows the block diagram of the detector object of the present invention.
    Figure 2.- Shows the block and connection diagram of the system incorporated by the handle in the fencing mode with foil.
    Figure 3.- Shows the block and connection diagram of the system incorporated by the shooter in sword fencing mode.
    Figure 4.- Shows the block and connection diagram of the system incorporated by the handle in the fencing mode with saber.

    PREFERRED EMBODIMENT OF THE INVENTION
    Figure 5 shows the circuit diagram of a preferred embodiment of the headdress detector object of the present invention with analog circuits. The figure shows the local oscillator (2) connected to the alternating signal output terminal (10). Said alternating signal can be obtained in the practice of the microcontroller itself (21) by taking the
    5
    10
    fifteen
    twenty
    25
    30
    35
    signal from one of its conveniently configured output terminals. The same applies to the generation of the alternating component of the mixed signal generator (3), which is capacitively coupled to a resistor connected to the power node to create the continuous component. The first continuous component detector (4) is composed of a low-pass filter (41) that eliminates the alternating component, a voltage divider (40) that helps to fix the continuous component in the signal input terminal (11) and, possibly, a window comparator (42) that modifies the state of its output voltage when the input voltage is within predefined ranges.
    The intermodulation product generator (5) is formed by an envelope detector (43) with polarized diode and capacitively coupled to the signal input terminal (11). This circuit meets the two requirements set forth in this document, both in the generation of a continuous component dependent on the amplitude of the coupled signal of the local oscillator (2), and in the generation of intermodulation products when in the signal input terminal ( 11) two different frequencies concur. The output provided by the envelope detector is amplified by a non-inverting amplifier (44) based on an operational amplifier and passes to the detector blocks connected to the output. The second continuous component detector (6) is a low-pass filter (45) and, possibly, a window comparator (46). The first alternating component detector (7) incorporates a low-pass filter (47) that allows the passage of the lower frequency intermodulation product followed by a diode-based peak detector (48), which provides a voltage proportional to the amplitude of the intermodulation product, and possibly a window comparator (49). An analogous technique is used in the second alternating component detector (8), this time using a high-pass filter (50), to select a higher frequency intermodulation product, a second peak detector (51) and, possibly a window comparator (52). The detector object of the present invention together provides four output signals available to be interpreted by the microcontroller. As a final stage in each of the blocks, the eventual existence of window comparators (42) (46) (49) (52) in charge of classifying the signals present at their input according to a series of predefined ranges has been considered. Taking into account the benefits offered by modern microcontrollers, this task can be assumed by the microcontroller itself.
    The application of the circuit presented is limited to the wireless detection equipment of headdresses for the sport of fencing, demanded for decades by practitioners of this sport, and of which there is a small number of 5 commercial products.
