Abstract

The invention relates to an off side detection system using teleindicators with enable the referees to obtain a signal indicating that an off side play has occurred. The system is comprised of a portable emitter which is activated by the referee by mechanical pulsing which will always be effected when the player who has the ball passes the ball to another player. The system also comprises a portable receiver which is carried by the assistant; said receiver has a button and can be activated by the assistant by pulsing it whenever a player is in an off side position. The system is characterised by providing a signal which is perceived by a person in order to indicate to this person that the ball has been passed by one player while another player was off side. With such a system, all the assistant has to do is to observe, once he has received the signal, if the ball is going towards the player who has been detected off side and to apply the off side rule.

Description

The invention relates to a system of teleindicators that is used to penalise rightly the offside play.
This system uses a portable teleindicador which is pressed manually and activates a receiver that other person will carry. The receiver is characterized, because it has a button of on/off, if you don't press the receiver's button, it will be disconnected. The receiver activates a signal which will be noticed by the person who carries it.
This system uses emitters and receivers that actually have already been developed, although they are used for other purposes.
In this sport there is a football device which has a concrete function and it is very different of mine. This device, incorporates an emitter in the assistant's flag and it is used when he wants to warn the referee about something.
Offside detection system resolves a complex problem as it is the offside. The problem that has the referee and the assistant is to penalise correctly a move, they have to be able to watch two simultaneous actions, which many times are made in a large distant between them, doing difficult its observation.
To understand better the problem, I will use the definition "offside rule" that says: It is not an offence in itself to be in an offside position.
A player is in an offside position if:

he is nearer to his opponents' goal line than both the ball and the second last opponent.

A player in an offside position is only penalised if, at the moment the ball touches or is played by one of his team, he is, in the opinion of the referee, involved in active play by:

interfering with play or
interfering with an opponent or
gaining an advantage by being in that position.

The rule clearly says that and offside position must be penalised if it carries out one of these conditions. We can conduce saying that to the difficulty of interpreting the rule, it is joined to see the actions of the players that take part in the move.
The purpose of this system, is not to say when the referee must penalised the offside, instead of it will make the perception of work easier and he will only have to interpret the offside rule. In order to get it, the system activates a signal which will advise that at same time that the signal is produced, a pass has been done while a player was in offside position. To get this signal, what the system pretend is distributing the work of perception of the move, so that one will control the action of touching or play of the ball, while the other one controls the position of the nearer adversary to the offside line that shows the second last opponent.
The systems is characterised by using an emitter which will carry the referee and will always activate when he sees that the player who has the ball, pass it. The action of pulsing the emitter will be so short as the kick of the own player.
The assistant who hasn't to be watching the ball, he will be watching the nearer player to the perpendicular line (on the touche line) that form the second last opponent. In this way, the receiver that carries, will be activated when the player passes this imaginary line and will keep activated while a player is in offside position.
The system allows three possibilities and are:

the referee pulses his emitter to watch a pass, the assistant doesn't activate the receiver because there aren't any player in offside position and the signal is not produced. The play has a pass without position, so this play is interpreted as a right move.
the assistant watches that a player is in an offside position and activates his receiver, at the same time the referee doesn't watch that any pass has been done and don't pulse his emitter. The play has position without passing, so this move is interpreted as a right move.
the assistant activates his receiver because a player is in offside position, at the same time the referee watches that a player pass the ball and pulses his emitter. Once the signal is produced, the assistant knows that the move has a pass with position and is when he has to interpret if the move carries out some of the conditions to be penalised as an offside move.

With its system simplify considerably the work of percepcion, as we match are senses obtaining more efficiency and security to take decisions.
Other advantage of the system is that, it takes advantage of the position of the referee and assistant are. The referee has the particularity of being where he wants and it is for that reason, he always tries to be near the ball or situates in a right angle to watch the move, although it has the disadvantage to be normally in front of the defence and it's difficult to image the perpendicular line which forms the second last opponent. To the assistant happens the opposite, he has limited the zone of movement and always runs for the touch line, but he always is in the same line than the second last opponent, with it, he can imagine the perpendicular line that forms the second last opponent, but for him is more difficult to see the move of the ball than the position of the second opponent. The system takes advantages of his best position to control and coordinate the action of penalising the offside move.
The system has different ways of coming true, although the purpose would be always the same, in fact, the system could be formed of two different frequency emitters which are activates by the way already described, activating a receiver that needs to receive the two frequencies at the same time to activate it self and the referee could also carry it to hear the signal.
The invention is described now by examples and with the reference to the attached pictures, in which:
Figure 1: example of teleindicator to carry in his hand. Emitter's activation push button (A); the emitter (B); battery (C); connection to load the battery (F); the emitter could need an antenna (E). The shape and design (N) of this emitter would adapt to the ergonomic needs of the person who has to carry it.
Figure 2: example of a teleindicator put on a whistle. Body of the whistle (G); push button that activates the emitter (H), this push button can be incorporated in the whistle or adapted in it. (I) would be the connection and can work as antenna, of the emitter (J), can be adapted in a watch, as on the figure 6, or in a pocket, or brazalet.
Figure 3: example of a receiver that produces an acoustic signal. The receiver (L), can be incorporated in a pocket or a brazalet, and actives a signal in the earphone (K), the receiver can carry a mechanism to control the volume.
Figure 4: example of earphone (K), that can be used to connect to figure 8 or figure 5.
Figure 5: example of a flag with emitter/receiver. This flag increase the actual loans. With this flag can send visual signal (AB); acoustic/vibrators signals that are activated while the push button keeps pulsed (R) and pulsing the push button (S) receives (or emits in the case it was an emitter) the signal. The emitter (T) can do the function of emitting one or two signals in function of how the system wants to be developed. The flag can incorporate a receiver (V); a battery (W), it can have an input (X) to load the battery; a stick of the flag (Z); and a antenna (Y) if the emitter/receiver need.
Figure 6: example of where can go an emitter which needs the figure 2 or figure 8, and example where can go the acoustic or vibrator signal.
Figure 7: example of a receiver acoustic/vibrator.
Figure 8: example of a receiver with push button (M) that activates and disconnects; the receiver (N); the battery (P); the connection (Q) to connect with the figure 4; antenna receiver (AC). Shape and design of this receiver (O) would adapt to the ergonomic needs of the person who has to carry it. The receiver can be carry a mechanism to control the volume for the output of the signal.
The diagrams show and example of how to use the system in a move.
Diagram 1 : the referee watches to the player that has the ball and the assistant activates his receiver because a player is in offside position.
Diagram 2: the referee pulses his emitter, when he sees a pass, the signal is produced because the receiver is activated by the assistant.
Diagram 3: the assistant leads his attention to the ball, in order to watch, if it leads to the player who was in the moment to hear the signal, in an offside position, and decides no to penalise the move, when he sees that the ball leads to other player.
The industrial application of this system does references to the necessary mechanism to applicate it, so that with this example of the figures is sufficiently explained how to make the necessary mechanism, without having to be the same to the figures, as these could suffer some modifications like waterproof the mechanism or having a different shape to the figure, without for it, changes the result of the innovation.

Claims

The offside detection system is characterised by producing a perceptible signal for human being, which is caused with the use of a portable emitter and a receiver.
The offside detection system is characterised by using a portable emitter that emits a determinated frequency and has a button that activates the emitter, during this emission as long as the button keeps pulsed.
The offside detection system is characterised by using a receiver that activates a perceptible signal for human being, this signal is produced when the receiver receives the emitter's signal.
The offside detection system is characterised by using a receiver with a button that activates the receiver. This will keep activated as long as the button is pulsed. So the signal that caused the receiver only is produced when both emitter and receiver keep pulsed at the same time.
The offside detection system is characterised by its way of doing, the referee shows with his emitter that a ball touches has been done, pulsing the emitter, at the same time the assistant activates the receiver when a player is an offside position. This system is characterised for getting a signal that shows that both actions have been produced at the same time, that means, a move in offside.
The offside detection system is characterised by doing with two different frequency emitters. By this way the signal will only produce if is receives the signal of both emitters.
The offside detection system is characterised by getting a signal that shows that two actions have been produced at the same time, independently of getting this signal.
