Description

WIRELESS SCORING SYSTEM FOR COMPETITIVE SWORDPLAY GAME
WITH NONMETALLIC SWORDS
Background of the Invention The weapons used in fencing sport, have blades made of steel, which in most of the cases generate physical pain during fencing touches, and represent a safety risk. It would be advantageous to eliminate the metal weapons from fencing sport, but in the same time to keep the capability of electrical detection of touches. Games with swords made of foam have been proposed for fencing, but none have the capability of the current invention which delivers precise electronic scoring system with wireless transmission of fencing touches, which makes it suitable for score-based competitions.
The rules for scoring in traditional fencing are complex, and at least one year of competitive experience is needed in order to understand how scoring rules are applied by the referees. One of the objects of this invention is to provide a scoring board apparatus which has the scoring rules incorporated in a micro-controller, which makes the fencing scoring rules simple, and easy to understand in the first day of training.

-2-In traditional fencing, the start and the stop of fencing rounds are done based on the verbal commands from the referee. This creates confusion if the referee makes calls to stop the fencing round right in the middle of a pending fencing action, and some scoring points are invalidated because it is not clear if the fencing touch occurred before or after the referee's call. The current invention offers the solution to control the scoring apparatus with a radio remote apparatus, which enables or disables instantly the part of the electrical circuit which validates the fencing touches in order to score points.
Another object of this invention is to make the start and stop commands sent by the radio remote apparatus visible such that the players can see when the buttons are operated on the radio remote apparatus. This feature is supported by current invention by adding a wrist collar apparatus, which has incorporated lighting devices to emit light of predefined colors when the radio remote apparatus is operated.
The current fencing scoring devices indicate the winner of each scoring point by light signals on the scoring board. But during a fencing round, the two players could move far from the scoring board, so they are not able to see whether a fencing action succeeded to create a valid scoring point. The current invention offers the solution to

-3-install lighting devices on the blades of the fencing weapon, allowing this way to introduce light signaling by emitting predefined colors of light when one of the players wins a scoring point. The same lighting devices installed on the blades of the fencing weapon, are used by the current invention, to emit lighting signals when the radio remote apparatus is operated either to start or end the fencing rounds.
Wireless scoring systems have been proposed for sport fencing, but none brings into play weapons made of foam, which allow fencing touches with all sides of the blade.
The Linsay U.S. Pat No. US20060100022 describes a wireless scoring system for fencing with weapons which have metallic blades The Aldridge U.S. Pat. No. 6,700,051 describes a system for scoring contact sports, and in particular karate.
Fencing and other contact sports are mentioned but not described with any particularity.
The Alvaro U.S. Pat. No. 6,612,968 shows a fencing weapon made of plastic having a switch at the top of the weapon, thus fencing touches are possible only with the tip of the weapon.

-4-The Delcayre U.S. Pat. No. 4,030,731 describes a scoring system which uses metallic weapons.

Summary of the Invention It is an object of this invention to provide a wireless scoring system for a competitive swordplay game, which uses nonmetallic swords with electric touch sensors on the blades.
Each player carries a mobile touch detector apparatus which transmits wirelessly to scoreboard controller apparatus, data packets which indicate fencing touches uniquely identifiable for each player.
The scoreboard is controlled by radio remote apparatus provided with two buttons, one labeled "GO" and one labeled "STOP". When buttons are pressed on the radio remote apparatus, lights of predefined colors are emitted by a wrist collar apparatus, and by electric lighting devices incorporated in the blades of the swords.
The rules for scoring are programmed in scoreboard controller apparatus which takes decisions to assign the scoring points throughout the swordplay bout.

-5-The player who wins a scoring point is indicated by the color of light emitted by the blade of the sword of the winner.
The rules for scoring include a priority-based scoring method to decide the winner of the scoring point when both players execute fencing touches simultaneously.
In other embodiments the priority-based scoring method can be simplified by reducing the number of steps in the method of assigning the priority.

In another embodiment of the invention, the sword 107 can be constructed without the lighting devices 202, 203, 205, 206, 215, and 216.
During the play of the swordplay game, the objective of each player is to touch with his/her sword, the opponent player. The purpose of this invention is to use an electric circuit to detect the touches during the swordplay game.
This feature is supported by the current invention by the electric circuit incorporated inside the mobile touch detector apparatus 112, which is monitoring the touch sensors 207, 208, 209, 210, 211, 212, 213, 214, 217, and 218 placed on the blade 204 of the sword 107.
In the current description of the invention and in the claims, the term "fencing touch" refers to the action where one player touches either the jacket 109 or the mask 106 of

-15-the opponent player, with at least two adjacent touch sensors out of the touch sensors 207, 208, 209, 210, 211, 212, 213, 214, 217, 218 from the blade 204 of his/her sword 107. For example when in current invention description, it is stated that "player 180 executed a fencing touch", it means that player 180 touched with his/her sword 107 either the jacket 109 or the mask 106 of player 190, such that at least two adjacent touch sensors out of 207, 208, 209, 210, 211, 212, 213, 214, 217, 218 from the blade 204 of sword 107 held by player 180 are in electrical contact with either the jacket 109 or the mask 106 worn by player 190.
According to the invention, the occurrences of said fencing touches executed by one player are captured by the mobile touch detector apparatus 112 carried by the player, and encoded in data packets which are transmitted through radio 111 to the radio 104 incorporated inside the scoreboard controller apparatus 103. Furthermore, the scoreboard controller apparatus 103 assigns scoring points based on the scoring rules preprogrammed in PCM 105, and then updates accordingly, the score digits on the scoreboard display apparatus 101. When the score reaches to a predefined maximum value, the player with the biggest score is declared the winner of the swordplay bout.
FIG. 3 shows the circuit incorporated inside the mobile touch detector apparatus 112 and how this circuit is

-16-electrically connected with the touch sensors 207, 208, 209, 210, 211, 212, 213, 214, 217, and 218, from the sword 107 of the player who carries the mobile touch detector apparatus 112. Furthermore, FIG. 3 also shows how the circuit incorporated inside the mobile touch detector apparatus 112 is electrically connected with the jacket 109 of the player who carries the mobile touch detector apparatus 112.
FIG. 3 illustrates the preferred embodiment of the electrical wiring inside the sword 107, the electrical circuit inside the sword 107 comprising:
an electrical wire 301, which is electrically connected with the touch sensors 207, 209, 211, 213, and 218;
an electrical wire 305, which is electrically connected with the touch sensors 208, 210, 212, 214, and 217;
a known electrical lighting device 302, which provides the source of light for the lighting devices 202, 203, 205, 206, 215, 216; and an electrical plug 200, which connects the wires 301, 303, and 305 with the electrical cable 114.
The cable 114 makes the electrical connection between the sword 107 and the mobile touch detector apparatus 112,

-17-furthermore the cable 114 comprising the electrical wires 304, 306, and 307.
The electrical wire 110 connects the jacket 109 to the electrical circuit incorporated inside the mobile touch detector apparatus 112.
The electrical lighting device 302 is connected to electrical wire 303, and through the plug 200 is connected to the electrical driver circuit 350. The circuit 350 is controlled by the PCM 113, in order to change the color of the light emitted by the lighting devices 202, 203, 205, 206, 215, 216, as described herein.
In the preferred embodiment, the circuit 350 is also used to detect when the cable 114 is plugged into the plug 200 of the sword 107. Furthermore the plug-state of the cable 114 is transmitted by PCM 113 through radio 111, to the scoreboard controller apparatus 103, which uses the signs 152 and 155 to indicate whether the swords 107 are plugged properly into the system.
The circuit incorporated inside the mobile touch detector apparatus 112, uses battery 324 as power source for the two known voltage regulators 328 and 329, which generate the voltages VREL and VDIG, respectively. The voltage VDIG is used to power the radio module 111 and the PCM 113. The voltage VREL is used to power the two known relays 322 and

-18-311. The voltage VDIG stays at nominal value as long as the switch 330 is closed. The voltage VREL can be powered down by the PCM 113, by disabling the voltage regulator 328 through the wire 327.
The two relays 322 and 311 are double pole double throw type.
The internal contact of relay 311 between terminals 309 and 314 is normally opened. The internal contact of relay 311 between terminals 310 and 315 is normally opened. The internal contact of relay 322 between terminals 318 and 325 is normally opened. The internal contact of relay 322 between terminals 320 and 326 is normally opened.
As part of the invention, when a player touches with his/her sword 107 the metallic surface of either one of the jackets 109 or one of the masks 106, an electric contact is created between at least one of the sensors connected to wire 301, and one of the sensors connected to wire 305.
The contact is created because the metallic surface of either the jacket 109 or the mask 106 creates an electrically conductive bridge between the sensors 207, 209, 211, 213, 218, and at least one of the sensors 208, 210, 212, 214, 217.

-19-As part of the invention, when a player touches with his/her sword 107, either the jacket 109 of the opponent player or the mask 106 of the opponent player, then inside his/her own touch detector 112, the voltage VREL propagates from wire 304, through plug 200, then through wire 301, then through touch sensors 207, 209, 211, 213, 218, then through the metallic surface of jacket 109 or mask 106 of the opponent player, then through at least one of the touch sensors 208, 210, 212, 214, 217, then through wire 305, then through plug 200, then through wire 307, reaching this way to power up the coil 308 of relay 311.
According to the invention, the function of relay 311 is to detect when one player touches with his/her sword 107, either the jacket 109 or the mask 106 of the opponent player.
The electrical wire 307 represents the input of the mobile touch detector apparatus 112, because the voltage VREL propagates through this wire when the player who carries the mobile touch detector apparatus 112, executes a fencing touch as described herein.
As part of the invention, when a player touches with his/her sword 107, his/her own jacket 109, the voltage VREL
propagates from wire 304, through plug 200, then through wire 301, then through the touch sensors 207, 209, 211,

-20-213, 218, then through the metallic surface of jacket 109, then through electrical wire 110, this way powering up the coil 317 of relay 322.
As part of the invention, when a player touches with his/her sword 107, his/her own mask 106, the voltage VREL
propagates from wire 304, through plug 200, then through wire 301, then through touch sensors 207, 209, 211, 213, 218, then through the metallic source of mask 106, then through electrical wire 108, then through jacket 109, then through electrical wire 110, this way powering up the coil 317 of relay 322.
According to the invention, the function of relay 322 is to detect when a player touches with his/her sword 107, either his/her own jacket 109 or his/her own mask 106.
FIG. 4 shows a timing diagram with the waveforms of the signals from the circuit incorporated inside the mobile touch detector apparatus 112 when the player who carries the mobile touch detector apparatus 112 executes a fencing touch as described herein.
FIG. 5 shows a timing diagram with the waveforms of the signals from the circuit incorporated inside the mobile touch detector apparatus 112, when the player who carries the mobile touch detector apparatus 112 touches with

-21-his/her sword 107 either his/her own jacket 109 or his/her own mask 106.
At time TO, in FIG. 4 and FIG. 5, the touch detector 112 is turned on manually by operating the switch 330, allowing this way to propagate the voltage from battery 324, to the voltage regulators 328 and 329.
In FIG. 4, the time T41 is the moment when the player who carries the mobile touch detector apparatus 112 executes a fencing touch as described herein. At time T41, at least two adjacent touch sensors out of 207, 208, 209, 210, 211, 212, 213, 214, 217, 218, from the sword 107 of the player who carries the mobile touch detector apparatus 112, are in electrical contact with either the jacket 109 or the mask 106 of the opponent player. Furthermore, the contact starts at time T41 and lasts until time T43.
The waveform 400 represents the contact between the touch sensors from the sword of a player and either the jacket or the mask of the opponent player. The waveform 400 is marked "ON" when the touch sensors from a sword of a player are in contact with the jacket or the mask of the opponent player, which is between times T41 and T43. The waveform 400 is marked "OFF" when the sword is not touching any jacket or any mask.

-22-For example if the player 190 executes a fencing touch, then at time T41, at least two adjacent touch sensors out of 207, 208, 209, 210, 211, 212, 213, 214, 217, 218 from the sword 107 of player 190, are in electrical contact with either the jacket 109 or the mask 106 of the player 180.
Furthermore, the touch sensors stay in contact with either the jacket or the mask until time T43.
The relay 311 detects when a player touches with his/her sword, either the jacket or the mask of the opponent player, as described herein.
Thus, at time T41 the voltage VREL propagates to the coil 308, as described herein.
Powering up the coil 308 causes the internal contact of relay 311 between terminals 314 and 309, to close.
The voltage VREL is propagated to terminal 314, through internal contact of relay 322, between terminals 325 and 319.
When the coil 308 is powered at time T41, the voltage VREL propagates from terminal 314 to terminal 309, reaching to coil 308, and bringing the relay 311 in a self-locking state. Thus, the coil 308 stays powered up after time T43.
The relay 311 can exit the self-locking state only if the voltage VREL is powered down.

-23-The voltage VDIG is propagated to terminal 315, through internal contact of relay 322, between terminals 326 and 321. Powering up the coil 308 causes the internal contact of relay 311 between terminals 315 and 310, to close. This causes to propagate the voltage VDIG from terminal 315 to terminal 310, reaching to PCM 113 through wire 312. At time TO, the voltage level on wire 312 is zero volts, because of the pull-down resistor 313. But after coil 308 is powered up at time T41, the voltage level of wire 312 becomes at time T42, equal with voltage VDIG.
According to the invention, the voltage level of wire 312 is a distinctive state of the touch detector circuit, and the electrical state of wire 312 represents that the player who carries the mobile touch detector apparatus 112 executed a fencing touch. Once the voltage level of wire 312 becomes equal with the voltage VDIG, it is stored to the same voltage level until the relay 311 is reset by dropping the voltage VREL to zero volts.
After time T42, the PCM 113 detects that voltage level of wire 312 has changed from zero volts to the level of VDIG
voltage. According to the invention, PCM 113 is programmed to generate data packets 401 when it detects that the voltage level of wire 312 has changed from zero volts to same level as VDIG voltage.

-24-As shown in FIG. 4, at time T44 the PCM 113 starts to transmit the data packet 401 through radio 111. According to the invention, inside the data packet 401, there is encoded information about which player touched with his/her sword 107, either the jacket 109 or the mask 106 of the opponent player.
After PCM 113 starts to transmit the data packet 401 at time T44, then at time T45 the PCM 113 disables the voltage regulator 328, through wire 327. This causes the voltage VREL to drop to zero volts at time T46, causing the relay 311 to reset. Furthermore the internal contact of relay 311 between terminals 315 and 310 opens, causing the voltage level on wire 312 to drop to zero volts, at time T47.
After time T47, the PCM 113 detects that the voltage level of wire 312 has changed from the level of VDIG
voltage to zero volts, and enables again the voltage regulator 328 at time T48. This causes the voltage VREL to go back to nominal value at time T49. Furthermore, after time T49 the mobile touch detector apparatus 112 to is ready to detect the next fencing touch in the swordplay bout.
In FIG. 5, the time T51 is the moment when the player who carries the mobile touch detector apparatus 112, touches with his/her sword 107, either his/her own jacket 109 or

-25-his/her own mask 106. At time T51, at least two adjacent touch sensors out of 207, 208, 209, 210, 211, 212, 213, 214, 217, 218, from the sword 107 of the player who carries the mobile touch detector apparatus 112, are in electrical contact with either his/her own jacket 109 or his/her own mask 106. Furthermore, the contact starts at time T51, and lasts until time T53.
The waveform 500 represents the contact between the touch sensors from the sword of a player and either his/her own jacket or his/her own mask. The waveform 500 is marked "ON"
when the touch sensors from the sword of a player are in contact with either his/her own jacket or his/her own mask, which is between times T51 and T53. The waveform 500 is marked "OFF", when the sword is not touching any jacket or any mask.
The relay 322 detects when a player touches with his/her sword, either his/her own jacket or mask, as described herein. Thus, at time T51 the voltage VREL propagates to the coil 317, as described herein.
Powering up the coil 317 causes the internal contact of relay 322 between terminals 325 and 318, to close.
Furthermore the voltage VREL propagates from terminal 325 to terminal 318, reaching to coil 317, and bringing the relay 322 in a self-locking state. Thus, the coil 317 stays

-26-powered up after time T53. The relay 322 can exit the self-locking state only if the voltage VREL is powered down.
When coil 317 is powered, the voltages VREL and VDIG are blocked from propagating to terminals 314 and 315, respectively, because the normally closed contacts of relay 322, are opened when coil 317 is powered. When coil 317 is powered, the voltage VDIG does not propagate to terminal 321 of relay 322, because the internal contact between terminals 326 and 321 is opened.
As shown in FIG. 3, the two relays 311 and 322 are connected together such that when a player touches his/her own jacket or mask, with his/her own sword, the voltage level of wire 312 will stay zero volts, as shown in FIG. 5.
Furthermore, the PCM 113 cannot transmit data packets 401 when the player who carries the mobile touch detector apparatus 112 touches with his/her sword either his/her own jacket or mask, because the voltage level of wire 312 stays zero volts. Moreover, due to the connection between the relays 311 and 322, a player will never receive a scoring point when touches his/her own jacket or mask with his/her own sword.
Powering up the coil 317 causes the internal contact of relay 322 between terminals 326 and 320, to close. This

-27-causes to propagate the voltage VDIG to terminal 320, reaching to PCM 113 through wire 316.
At time TO, the voltage level on wire 316 is zero volts, because of the pull-down resistor 323. But after coil 317 is powered up at time T51, the voltage level of wire 316 becomes at time T52, equal with voltage VDIG.
According to the invention, the voltage level of wire 316 is a distinctive state of the touch detector circuit, and the electrical state of wire 316 represents that the player who carries the mobile touch detector apparatus 112 touched with his/her sword, either his/her own jacket or mask.
Once the voltage level of wire 316 becomes equal with the voltage VDIG, it is stored to the same voltage level until the relay 322 is reset by dropping the voltage VREL to zero volts.
After time T52, the PCM 113 detects that voltage level of wire 316 has changed from zero volts to the level of VDIG
voltage. According to the invention, PCM 113 is programmed to generate data packets 501 when it detects that the voltage level of wire 316 has changed from zero volts to same level as VDIG voltage.
As shown in FIG. 5, at time T54 the PCM 113 starts to transmit the data packet 501 through radio 111. According

-28-to the invention, inside the data packet 501, there is encoded information about which player touched with his/her sword 107, either his/her own jacket 109 or his/her own mask 106.
After PCM 113 starts to transmit the data packet 501 at time T54, then at time T55 the PCM 113 disables the voltage regulator 328, through wire 327. This causes the voltage VREL to drop to zero volts at time T56, causing the relay 322 to reset. Furthermore the internal contact of relay 322 between terminals 326 and 320 opens, causing the voltage level on wire 316 to drop to zero volts, at time T57.
After time T57, the PCM 113 detects that the voltage level of wire 316 has changed from the level of VDIG
voltage to zero volts, and enables again the voltage regulator 328 at time T58. This causes the voltage VREL to go back to nominal value at time T59. Furthermore, after time T59 the mobile touch detector apparatus 112 to is ready to detect the next fencing touch in the bout.
When a player executes a fencing touch, the wire 316 stays at zero volts, as shown in FIG. 4, because the coil 317 of relay 322 is powered only when the touch sensors from the sword of a player touch either his/her own jacket or mask, as described herein.

-29-An object of the current invention is to provide an efficient system of touch sensors capable to detect any fencing touches. FIG. 6 illustrates the shape of the touch sensors 207, 208, 209, 210, 211, 212, 213, 214, 217, and 218, in the preferred embodiment.
In FIG. 6 (a) is shown a three dimensional view of the blade 204. In FIG. 6 (b) the sensors are shown without the blade, in order to illustrate the shape of the touch sensors.
As part of the invention, the touch sensors 217 and 218 are placed on the tip of the blade 204. When a player touches with the tip of his/her sword 107, either the jacket 109 or the mask 106 of the opponent player, then the metallic surface of either the jacket or the mask, creates an electric contact between the sensors 217 and 218.
In other embodiments, in order to increase the chances of detecting a fencing touch, on the tip of the blade can be placed a plurality of touch sensors, which can be shaped as circle segments.
As part of the invention, the touch sensors 213 and 214 are shaped as two ring segments of equal sizes. As shown in FIG. 3, the touch sensors 213 and 218 are connected to the wire 301, and the touch sensors 214 and 217 are connected to the wire 305. Thus, during a fencing touch, the metallic

-30-surface of either the jacket 109 or the mask 106 can be detected if it creates an electrical contact between 213 and 217, or between 213 and 214, or between 214 and 218, or between 218 and 217.

In FIG. 6, the touch sensors 212 and 211 are shaped as rings. , In the preferred embodiment the touch sensors 207, 208, 209, 210, 211, and 212 are shaped as rings, and any two adjacent rings are connected to another wire inside the blade 204, as shown in FIG. 3. Thus, during a fencing touch, the metallic surface of either the jacket 109 or the mask 106 can be detected if it creates an electrical contact between 212 and 211, or between 211 and 210, or between 210 and 209, or between 209 and 208, or between 208 and 207.

In other embodiments the touch sensors can be a plurality of ring segments, and each touch sensor connected to a different wire inside the blade of the sword.

In other embodiments the touch sensors can mix between a plurality of rings and a plurality of ring segments, and each touch sensor connected to a different wire inside the blade of the sword.

-31-In traditional fencing sport the referee applies complex rules when assigns scoring points to the players during the bout. According to the invention, a scoring method is programmed in the PCM 105, such that the scoring points are decided by the scoreboard controller apparatus 103, thus eliminating the need of a referee in the swordplay game.
FIG. 7 shows the diagram of the scoring method implemented in the state machine programmed in the PCM 105.
In state 700 the "GO" button 117 is pressed, and then the two players start a round of swordplay. After the "GO"
button 117 is pressed, the PCM 105 enables the decoding of any incoming data packet 401, and then the scoreboard controller apparatus 103 moves to state 701.
When players execute fencing touches, the PCM 113 incorporated in the mobile touch detector apparatuses 112 generate data packets 401, which are transmitted through the radios 111, as described herein. According to the invention, in state 701, the PCM 105 waits for the data packets 401 to be received.
After the PCM 105 receives data packets 401 through radio 104, the scoreboard controller apparatus 103, moves to state 702.

-32-According to the invention, in state 702 the PCM 105 checks if the two players executed fencing touches simultaneously.
If the PCM 105 determines in state 702, that in state 701 the players did not execute fencing touches simultaneously, then the scoreboard controller apparatus 103 moves to state 789.
According to the invention, in state 789 the PCM 105 disables the decoding of any incoming data packets 401, and then the scoreboard controller apparatus 103 moves to state 790.
According to the invention, in state 790, the PCM 105 assigns a scoring point to the player who was first to execute the fencing touch in state 701, and the score is then incremented accordingly on the scoreboard display apparatus 101, for the player was first to execute the fencing touch.
If the PCM 105 determines in state 702, that in state 701 the two players did execute fencing touches simultaneously, then the scoreboard controller apparatus 103 moves to state 709.
According to the invention, in state 709 the PCM 105 disables the decoding of any incoming data packets 401, and

-33-then the PCM 105 applies the priority-based scoring method 710.
According to the invention, the priority-based scoring method 710 is applied when the two players execute fencing touches simultaneously.
In FIG. 8 is shown the diagram of the state machine programmed in PCM 105, which applies scoring rules according to the preferred embodiment of the priority-based scoring method 710.
As shown in FIG. 8, from state 709 the scoreboard controller apparatus 103 moves to state 801 which is the first state of the priority-based scoring method 710.
The priority-based scoring method 710, comprising:
a method of assigning priority;
a method of using the priority after is assigned; and a method to indicate which player has priority.
A method of assigning priority is supported in the state machine from FIG. 8, by the sequence of the states 802, 803, 804, 805, 806, and 830.

-34-A method of using the priority after is assigned, is supported in the state machine from FIG. 8, by the sequence of the states 801 and 860.
A method to indicate which player has priority is supported in the state machine from FIG. 8 by the state 870.
According to the invention, in state 801 the PCM 105 checks if priority is already assigned to one of the two players.
If one of the players already had priority in the moment when the scoreboard controller apparatus 103 entered the state 801, then the scoreboard controller apparatus 103 moves to state 860.
According to the invention, in state 860, the scoreboard controller apparatus 103 assigns a score point to the player who already had priority in the moment when the scoreboard controller apparatus 103 entered the state 801.
The score digits are updated on the scoreboard display apparatus 101, such that to have an incremented value for the player who won the scoring point in state 860.
If none of the two players had priority already assigned when scoreboard controller 103 entered the state 801, then the scoreboard controller 103 moves to state 802.

-35-According to the invention, in state 802 the PCM 105 checks if the score is equal.
If in state 802 the PCM 105 determines that score is not equal then the scoreboard controller 103 moves to state 830.
According to the invention, in state 830 the scoreboard controller apparatus 103 assigns priority to the player with the lowest score.
If in state 802 the PCM 105 determines that score is equal then the scoreboard controller 103 moves to state 803.
According to invention, when the scoreboard controller apparatus 103 is in state 803 the scoreboard display apparatus 101 displays a distinctive sign 910 for each player, as shown in FIG. 9 (a).
In the preferred embodiment, by displaying the sign 910, the priority-based scoring method 710 prompts the players 180 and 190 to take part in the process of assigning the priority.
In the preferred embodiment, the sign 910 is a rectangle with a two digit number inside, and the number is "00".
Furthermore, the rectangle from the sign 910 has a dashed

-36-border line, wherein the border line is blinking in order to attract visual attention to the players.
In the preferred embodiment, the scoreboard controller apparatus 103 is programmed to stay in the state 803 until receives data packets 501 from each of the mobile touch detector apparatuses 112 carried by the players 180 and 190.
As described herein, the PCM 113 incorporated inside the mobile touch detector apparatus 112 transmits data packets 501 when the player who carries the mobile touch detector apparatus 112, touches with the touch sensors from his/her sword 107, either his/her own jacket 109 or mask 106.
As part of the invention, when the prompt sign 910 is displayed for each player on the scoreboard display apparatus 101, the scoreboard controller apparatus 103 expects for each of the players, 180 and 190, to touch their own jackets 109 or masks 106, with the touch sensors from their own swords 107.
After the data packets 501 are received by the PCM 105, from each mobile touch detector apparatus 112, the scoreboard controller apparatus 103 moves to state 804.

-37-According to the invention, the data packets 501 are ignored by PCM 105, unless the scoreboard controller 103 is in state 803.
According to the invention, when the scoreboard controller apparatus 103 is in state 804, the scoreboard display apparatus 101 displays a distinctive sign 911 for each player, as shown in FIG. 9 (b).
In the preferred embodiment, the sign 911 is a rectangle with a two digit number inside, and the number has a random value between 1 and 99. Furthermore, the rectangle from the sign 911 has a solid border line.
In the preferred embodiment, the scoreboard controller apparatus 103 generates one random number for each player, immediately after the data packet 501 is received from the mobile touch detector apparatus 112 carried by the player.
As shown in FIG. 9 (b), in the preferred embodiment, the random number generated for player 180 is displayed inside the sign 911 placed below the score number 156, and the random number generated for player 190 is displayed inside the sign 911 placed below the score number 157.
According to the invention, after a random number is generated for each player, the scoreboard controller apparatus 103 moves to state 805, where the two random

-38-numbers are compared by PCM 105. If in state 805, the PCM
105 determines that the two random numbers are equal, then the scoreboard controller apparatus 103 returns to state 803, in order to generate another set of random numbers by executing again the states 804 and 805.
As shown in FIG. 8, the states 803, 804 and 805 are executed in a loop, until the numbers generated inside the signs 911 are not equal.
If in state 805, the PCM 105 determines that the two random numbers displayed inside the signs 911, are not equal, then the scoreboard controller apparatus 103 moves to state 806 where the priority is assigned to one of the players, based on the values of the random numbers.
In the preferred embodiment, in state 806 the priority is assigned to the player who has the biggest random number displayed inside the sign 911.
Furthermore, in the preferred embodiment, the scoreboard apparatus controller 103 is provided with hardware peripherals 102, such as a keypad, which can configure the scoreboard controller apparatus 103 before the bout starts.
The keypad from peripherals 102 can configure scoreboard controller apparatus 103 to choose whether in state 806, the priority is assigned either to the player who has the biggest number or the smallest number.

-39-According to the invention, after the priority is assigned to one of the players, either in state 830 or in state 806, the scoreboard controller apparatus 103 moves to state 870.
In the preferred embodiment, when the scoreboard controller apparatus 103 is in state 870, on the scoreboard display apparatus 101 is displayed a distinctive sign 912, to indicate which player has priority.
When the priority is assigned to the player 180 the sign 912 is displayed below the score number 156 as shown in FIG. 9 (c) and when the priority is assigned to the player 190 the sign 912 is displayed below the score number 157 as shown in FIG. 9 (d).
According to the invention, when the scoreboard controller apparatus 103 applies the priority-based scoring method 710, either player can receive priority, but only one player can have priority at one time.
In the preferred embodiment, the sign 912 is a letter "P"
inside of a rectangle with a solid border line.
According to the invention, the score does not change when the scoreboard controller apparatus 103 executes the states 802, 803, 804, 805, 806, 830, and 870.

-40-According to the invention, after completing the priority-based scoring method 710, the scoreboard controller apparatus 103 returns to state 700, where PCM
105 waits for the "GO" button 117 to be pressed when the next round of swordplay begins.
According to the invention, any time when the "STOP"
button 118 is pressed, the scoreboard controller apparatus 103 returns to state 700.

the background of the image 151 is set to a predefined color; and the lighting devices 202, 203, 205, 206, 215 and 216 emit light of predefined colors, such that to distinguish which player is the winner of the scoring point, and which player executed the fencing touch second.
For example a green rectangle signifies "the player was first to execute a fencing touch" and a blue rectangle signifies "the player was second to execute fencing touch".

-42-Then if both players execute fencing touches, but player 180 was faster than player 190, then on the scoreboard display apparatus, the sign 153 will be a blinking green rectangle and the sign 154 will be a blinking blue rectangle. Furthermore, in this particular example the player 180 receives a scoring point because in state 790 is detected that he/she was first to execute a fencing touch, so in this case the green rectangle also signifies that the player 180 won the scoring point.
In the preferred embodiment, after PCM 105 determined in state 702 that the players executed simultaneous fencing touches, the players are informed that the fencing touches were executed simultaneously, by the following visual signals:
the signs 153 and 154 are set to the same predefined color; and the lighting devices 202, 203, 205, 206, 215 and 216 emit light of the same predefined color from both sword.
In the preferred embodiment the priority assigned to one of the players is cancelled on the first occurrence when a scoring point was obtained by either player, in either state 860 or 790. When the priority is canceled, the sign 912 is removed from the frame of the scoreboard display apparatus 101.

-43-Furthermore, in the preferred embodiment, the keypad from peripherals 102 can configure the scoreboard controller apparatus 103 before the bout starts, in order to choose whether the priority cancelation is allowed only when score points are assigned in state 860, after the players execute fencing touches simultaneously.
