Definitions

  • the present invention relates to a method and a system for detecting an offside situation during a game of football (soccer).
  • football usually at least two referee's (a referee and a linesman) are to referee the play.
  • An important rule to be observed and refereed is offside. Offside may occur if a first player, usually an offensive player, of a first team is located between the goalkeeper and all the other players of the second team. If another player of the first team passes the ball to the first player at the moment that the first player is between the goalkeeper and the other players, the first player is deemed to be offside.
  • the linesman is to detect such a situation and to raise the flag to indicate to the referee that the first player is offside.
  • the linesman In order to determine whether the first player is offside, the linesman needs to determine a position of the first player of the first team with respect to a position of the players of the second team exactly at the moment when another player of the first team kicks the ball towards the first player.
  • the linesman commonly keeps the ball in sight and as soon as the ball is kicked, he changes his sight towards the first player. Although the change of sight occurs in a very short period, e.g. several milliseconds, the position of the first player and/or a number of the players of the second team may have changed considerably. Further, other players may obstruct the sight of the kick of the ball. Also, depending on the position of the referee with respect to the first player of the first team and some of the players of the second team, it may be that the linesman misjudges the relative position of the players. As a consequence of the aforementioned reasons and possibly other reasons, the linesman often misjudges and, when in doubt, calls for offside, although the first player was actually not offside.
  • the object is achieved in a method for detecting an offside situation during a soccer game.
  • the method comprises generating a detection signal when a ball is kicked by a first player and supplying the detection signal to a signaling system.
  • the signaling system generates an observable signal to be observed by a referee, in response to receipt of the detection signal.
  • a referee may be the actual referee or may be a linesman or may be any other person observing the game.
  • the referee may keep primarily a possibly offside player in sight, instead of the ball. There is no need for the referee to observe the (kick of the) ball.
  • the term 'kick of the ball' is intended to refer to any kind of contact with the ball by a player that may or will lead to offside.
  • the observable signal is generated.
  • the referee keeping the possibly offside player in sight can immediately determine whether the player is at that moment, i.e. the moment of the kick of the ball, actually offside.
  • a further referee may observe the ball and, using a suitable system, the further referee may activate a detection signal generator, e.g. by pushing a button, for generating the detection signal.
  • a detection signal generator e.g. by pushing a button
  • the method further comprises sensing a sound signal produced by the ball; processing the sound signal in order to determine whether the ball is kicked; and if it is determined that the ball is kicked, generating the detection signal.
  • a sound vibration is generated in the ball.
  • the sound vibration may be sensed.
  • other events may generate a sound vibration in the ball. Therefore, any sensed sound signal is processed, e.g. a comparison with a predetermined sound signal of a kick of the ball or spectral analysis. Then, if it is determined that a sensed sound is the sound of a kick of the ball, the detection signal is generated.
  • the moment of determination of kicking the ball is not dependent on the subjective observation of a person, but is objectively determined by electronic means.
  • the method generating a detection signal comprises compiling the detection signal, a content of the detection signal comprising at least one element of the group comprising detected sound information data and a ball identification code.
  • the detection signal may be compiled from a number of kinds of information. For example, if a number of balls may be used, each ball may comprise its own identification number in order to prevent that a false or erroneous observable signal is generated as a consequence of a detection signal generated in another ball.
  • the detected sound information may be used to control a level of the observable signal thereby providing information to the referee how hard the ball was kicked. If only a soft kick was given, the referee may determine that the ball was not intended to be kicked towards the possibly offside player presuming that the distance between the ball and the offside player is large.
  • the detection signal is generated in the ball.
  • the method comprises wirelessly transmitting the detection signal from the ball to the signaling system.
  • the observable signal comprises a signal selected from the group comprising an audible signal, a visual signal, and a tangible signal.
  • a sound signal may be provided to the referee.
  • a light signal may be provided.
  • a tangible signal may be provided to the referee. In an embodiment two or more of these signals are provided to the referee.
  • the step of generating an observable signal comprises generating a vibration in an object to be held by the referee, the object in particular being a flag handle.
  • other signal generators may be arranged in the flag handle, such as an audible signal generator and/or a visible signal generator.
  • the present invention further provides a system for performing the method.
  • the system for detecting an offside situation during a soccer game comprises a detection signal generator for generating a detection signal when a ball is kicked by a player; a detection signal transmission system for supplying the detection signal from the detection signal generator to a signaling system; and an observable signal generator comprised in the signaling system for generating, in response to receipt of the detection signal, an observable signal to be observed by a referee.
  • the detection signal generator is arranged in the ball.
  • the detection signal generator comprises a sound sensing means, in particular a microphone; and a sound processing means coupled to the sound sensing means for processing a sound signal received from the sound sensing means in order to determine whether the ball is kicked.
  • the detection signal transmission system is a wireless transmission system, in particular operating at a frequency that is suitable to transmit over a distance of at least the distance of a diagonal of a play field. Considering that the diagonal is the largest possible distance between the ball and a referee, a wireless signal transmitted from the ball should at least be carried over such a distance. In practice, a frequency of 433 MHz appeared to be suitable. A transmission frequency may also be selected upon consideration of a requirement of a license to use such a frequency.
  • the signaling system comprises a flag, the observable signal generator being arranged in a part of the flag, in particular in a flag handle.
  • the signaling system comprises as an observable signal generator at least one of an audible signal generator, a visible signal generator and a tangible signal generator.
  • the method and system according to the present invention may as well be employed in determining a handball, i.e. a foul by touching the ball with a hand.
  • the method and system may also be employed for assisting a referee in determining which player was the last player to touch the ball before the ball went outside the play field.
  • the method and system may be employed for assisting a referee in determining whether a ball passed a goal line
  • a method is illustrated as a block diagram comprising a number of method steps.
  • a system for performing the method may be in a power safe mode 101 in order to prevent a low energy level, when the system is to be used.
  • the system is started in step 102.
  • the system may be started by switching the system on using a suitable means, such as a start button or a remote controller.
  • the system may be automatically started, when it is detected that apart of the system, e.g. a ball, is moved.
  • a kick against a ball is to be detected and to be signaled to a referee, in practice usually a linesman of a football (soccer) game.
  • a sound is produced by the ball.
  • the sound may be sensed by a suitable sensor, such as a microphone, as shown by step 103 in Fig. 1A .
  • the kick of the ball may be detected by other suitable systems, such as a button to be activated by a further referee, or by image processing.
  • the sound sensing means e.g. the microphone, may be located at any suitable location.
  • the sound sensing means is arranged in the ball.
  • a sound level of the sound produced by the ball is much higher than the sound level of a sound produced in the surroundings, e.g. by the players and/or spectators. Hence, the sound produced by the ball is easily distinguishable.
  • the sensed sound may be the sound produced due to a kick of the ball, including a header or a contact by a knee or any other contact of a player with the ball, i.e. any contact with a player that may lead to offside.
  • the sensed sound may as well be produced due to any other occurrence that may not lead to offside, such as a sound when the ball hits the ground. Therefore, in step 104, the sensed sound is processed in order to determine whether the sound was due to a kick.
  • the sensed sound may be digitized using a suitable analog-to-digital (A/D) converter and processed by a suitable microcontroller.
  • the processing may include comparing the sensed signal with a predetermined signal, which predetermined signal is the signal of a kick of the ball.
  • the processing may include, instead or additionally, spectral analysis of the sensed sound signal. Also other processing techniques may be employed.
  • step 105 it is determined whether the ball was kicked, or not. If it is determined that the ball was kicked, a detection signal is generated in step 106. If it is determined, in step 105, that the ball was not kicked, the method returns to step 103.
  • a signaling system for use in an embodiment of the method according to the present invention may be in a power safe mode as indicated by method step 111.
  • the signaling system may be activated from the power safe mode by pushing a button or by any other suitable means.
  • the signaling system is configured to receive a detection signal as generated in accordance with the present invention, for example in accordance with embodiment as illustrated by Fig. 1A .
  • the signaling system is sensing whether a detection signal is received. If it is determined that the detection signal is received, an observable signal is generated. Such an observable signal may be an audible signal, a visible signal or a tangible signal, or a combination thereof. If it is determined that no detection signal is received (step 114), the method returns to step 113.
  • Fig. 2A shows an embodiment of a system for generating a detection signal.
  • the system is comprised in a ball Ba.
  • the system comprises an energy source ES 3a , a sensing means SM, a processing means PM and a transmission means TM.
  • the energy source ES 3a is configured to supply power to the other components.
  • the energy source ES 3a may be any kind of suitable energy source, for example a battery, possibly a rechargeable battery.
  • the battery may advantageously be a small battery, e.g. a coin-shaped battery.
  • the sensing means SM may comprise a microphone for sensing a sound signal produced by the ball Ba, when it is kicked. Instead or additionally, the sensing means SM may comprise an acceleration sensor for measuring an acceleration of the ball Ba. Other suitable sensing means SM may as well be employed, possibly in combination.
  • the sensing means SM outputs a sensed signal, e.g. a sound signal, and the sensed signal is supplied to the processing means PM.
  • the processing means PM may process the sensed signal for determining from the sensed signal whether the ball Ba was kicked.
  • the processing means PM solely processes the sensed signal to prepare the sensed signal for transmission, thereby lowering power consumption of the processing means PM.
  • the processed sensed signal is output by the processing means PM and is supplied to the transmission means TM.
  • the transmission means TM receives the output of the processing means PM and transmits the output, for example through a wireless transmission channel. If the processing means PM solely prepare the sensed signal for transmission, the transmission means TM continuously transmits the output of the processing means PM. In such an embodiment, the sensed signal is further processed at the receiver side, e.g. the signaling system, as is explained hereinafter. In an embodiment, wherein the processing means PM solely o,utputs, a detection signal, when it is determined that the ball Ba was kicked, the transmission means TM only transmits now and then, i.e. at times that a detection signal is output by the processing means PM. Thus, in such an embodiment, the power consumption of the transmission means TM may be relatively low.
  • a signaling system may be comprised in a flag F1 of a linesman.
  • the signaling system may comprise a receiver means RM, a controller means CM, an actuator Ac and an energy source ES F1 for supplying power to the aforementioned components of the signaling system.
  • the receiver means RM is configured to receive a signal transmitted by the system of Fig. 2A .
  • the signal may be a signal comprising a sensed signal and/or a detection signal as above described.
  • the controller means CM is configured to receive the received signal from the receiver means RM.
  • the controller means CM determines from the received signal whether the ball Ba ( Fig. 2A ) was kicked. In case the received signal comprises a detection signal, the controller means CM may directly determine that the ball Ba was kicked. If the received signal does not comprise a detection signal, but does comprise the sensed signal, the controller means CM may comprise a processor for processing the sensed signal in order to determine whether the ball Ba was kicked based on the sensed signal. If it is determined that the ball Ba was kicked, an actuation signal is transmitted to the actuator Ac, which in response generates an observable signal.
  • the actuator Ac may be a light output device, e.g. a lamp or LED, a sound generating device or a vibration generating device for generating a tangible signal, for example.
  • a vibration generating device may be an eccentric motor means, for example.
  • Fig. 3 shows a graph of a sound signal produced by a ball when the ball is kicked.
  • the horizontal axis represents time in milliseconds; the vertical axis represents a sound level (amplitude) on a logarithmic scale. Based on the amplitude and/or frequency content of the sound signal, e.g. using spectral analysis, it may be determined what caused the signal, in particular whether the sound signal was due to a kick against the ball.
  • Fig. 4 shows a cross-section of a ball Ba in accordance with an embodiment of the present invention.
  • the ball Ba comprises an inner ball IB and an outer ball OB. Between the inner ball IB and the outer ball OB a detection system circuit DSC is positioned.
  • the detection system circuit DSC may comprise the components as shown in Fig. 2A , i.e. an energy source ES Ba , a sensing means SM, a processing means PM and a transmission means TM.
  • the detection system circuit DSC may be arranged on a flexible printed circuit board (PCB) such that the PCB may assume a rounded/spherical shape in accordance with the round/spherical shape of the ball.
  • the PCB is not flexible, but is preshaped in accordance with the shape of the ball Ba.
  • the energy source e.g. a coin shaped battery
  • the electronic components e.g. a sensing means, a processing means and/or a transmission means, are preferably arranged at a second, side of the PCB, the second side being opposite to the first side, i.e. between the inner ball IB and the PCB.
  • the battery may protect the electronic components against damage due to a kick at the ball Ba.
  • the transmission means of the detection system circuit DSC may comprise an antenna, in particular a loop antenna, for transmitting a detection signal or a detected signal.
  • the loop antenna may be substantially two-dimensionally shaped and arranged on the PCB.
  • the dimensions of the loop antenna may be, for example, 35 x 20 mm or 50 x 30 mm.
  • the smaller antenna having dimensions 35 x 20 mm has a suitable transmission range and may be preferred due to its dimensions.
  • the larger antenna having dimensions 50 x 30 mm is relatively large, but may be preferred due to its relatively low energy consumption.
  • a motion detection element may also be comprised in the detection system circuit DSC.
  • a piezo element may be arranged between the inner ball IB and the PCB.
  • pressure is applied to the piezo element, which in response outputs an electrical signal.
  • the electrical signal may be employed to indicate that the ball Ba is moving and the detection system is to leave a power safe mode ( Fig. 1A ) and to start.
  • the electronic components may be made from SMD components.
  • the weight of the DSC may be about 10 g.
  • Fig. 5 shows a flag handle FH of a flag to be used by a linesman, i.e. one of the referee's, during a football (soccer) match.
  • the flag handle FH comprises a signaling system in accordance with the present invention and may, for example, be used in combination with the ball Ba as illustrated in Fig. 4 .
  • the flag handle FH comprises a battery level indicator LI indicating an energy level of a battery comprised in the flag handle FH and/or a energy level of the battery comprised in the ball Ba in order to prevent that either battery energy level will become too low for operation during a match.
  • the flag handle FH may further comprise a switch SW for switching the signaling system on or off.
  • the switch SW may be a push button, for example.
  • the linesman may push the switch SW, when a possible offside situation occurs such that the signaling system only provides the observable signal in such a situation instead of during the whole match.
  • the flag handle FH may further comprise a ball selector switch BS. Presuming that the flag handle FH is to operate with the ball Ba as shown in Fig. 4 , each ball Ba may have an identification code. The identification code may be transmitted with the transmitted signals. The use of an identification code prevents that signals from any other ball, not used in the match, are received and interpreted, which could lead to misjudgments.
  • the ball selector switch BS allows to use the flag and flag handle FH in combination with a number of balls.
  • the flag handle FH may comprise a memory reader MR e.g. comprising a subscriber identity module (SIM) card reader.
  • the memory reader MR may receive and read a memory card SIM.
  • SIM subscriber identity module
  • On the memory card one or more identification codes of a number of corresponding balls is stored.
  • the identification code of the ball to be used in the match may be selected from the memory card.
  • the method and system according to the present invention may as well be advantageously used for assisting a referee to determine which player had the last contact with the ball.
  • the method and system allow determining whether an apparent contact with the ball was an actual contact with the ball, since the method and system may indicate when there is a contact with the ball.
  • the method and system may assist in detecting a handball, i.e. a contact of a hand with the ball.
  • Such a contact detection method and system may as well be employed for assisting a referee in other games and sports, such as volleyball.
