DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0038] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

[0039] Some aspects of the invention may be directed to a system and devices for training soccer players. The system may include a rebound unit at which a player may direct a ball and receive the ball back from the rebound unit in a predetermined and optionally adjustable angle. The system may further include one or more defense player simulation devices that simulates a defense player to be passed by the player. In some embodiments, each defense player simulation device may include indicator(s) for indicating to the player at least one of: from which side of the device the player should pass, by which foot to kick the ball using which part of the shoe, and the like. In some embodiments, the system may include a controller for controlling adjustable indicators (e.g., signs, signals, marking, etc.) to be included or attached to the one or more defense player simulation devices and/or the rebound unit. The adjustable indicators may be controlled (either by the controller or manually) to provide game instructions to the player. As used herein "game instructions" may include any instructions that may be provided to a user (e.g., a player, a coach, etc.) by indicators such as, marking, signals, signs, lights, sounds, a combination thereof, etc. that are related to a way to play (e.g., indicate to a user what actions to take and when to take them). For example, the "game instructions" may include kicking or otherwise hitting the ball, in order to direct the ball in a certain direction, passing the ball from a certain side of an element placed on the field, which foot to use for kicking the ball, in which part of the shoe to hit, and the like. [0040] In some embodiments, the system may further include one or more sensors (e.g., cameras, movement sensors and the like) for detecting a location of the player and/or the ball on the field. In some embodiments, the controller may be configured to determine the game instructions based on the location of the player and/or the ball received from the sensor, and/or based on a predetermined training plan.

[0041] Reference is made to Figs. 1A and IB which are illustrations of a top section and an isometric view of a rebound unit for soccer training, respectively, according to some embodiments of the invention. A rebound unit 100 for soccer training may include a base 110, at least one rebound surface(s) 120 and/or 130 and at least one tunnel 140. Tunnel 140 may include a tunnel inlet 142 and a tunnel outlet 144. Tunnel 140 may have a cross section larger than an outer diameter of a soccer ball (e.g., soccer ball 10). In some embodiments, the shape of tunnel 140 may be such that when base 110 is placed on the ground soccer ball 10 entering inlet 142 may be directed towards outlet 144.

[0042] In some embodiments, base 110 may be made from any suitable material, for example, polymers such as polyesters, wood, metals or a combination thereof. In some embodiments, base 110 may include an outer shell made from a polymer filled with water or other filling material (e.g., foam, sponge, etc.).

[0043] The rebound surface may be any surface of base 110 that may return or otherwise change the direction of movement of ball 10 upon engaging with the rebound surface. In some embodiments, rebound surface 120 may be substantially flat (as illustrated). In some embodiments, the rebound surface may have a shape designed to return the ball at a predetermined direction. For example, rebound surface 120, 130 may be convex (not illustrated) and/or rebound surface 130 may be concaved (as illustrated). In some embodiments, rebound unit 100 may include more than one rebound surfaces, for example, the 4 rebound surfaces illustrated in Figs. 1 A and IB. [0044] In some embodiments, rebound unit 100 may further include at least one sensor 180 for detecting ball 10 engaging base 110. In some embodiments, sensor 180 may be a camera (e.g., 360° camera), a motion sensor, a volumetric sensor, a piezoelectric sensor, Near Field Communication device (NFC) and the like. One or more sensors 180 may be attached to base 110 at any place required for sensing an engagement of soccer ball 10. In some embodiments, rebound unit 100 may further include or may be in communication with a processor (e.g., a processor 1120 and/or the processor of a mobile device 20 illustrated in Fig. 14). In some embodiments, the processor may be configured to receive from sensor 180 a first actual location on rebound unit 100 at which ball 100 engaged rebound unit 100, for example, a location on rebound surface 120. In some embodiments, the processor may further determine a second required location the rebound unit 100 at which ball 100 should engage rebound unit 100, for example, tunnel inlet 142 (as illustrated) and present the second required location via a user interface, for example, a screen of a mobile device (e.g., mobile device 20, such as, a smartphone, a smartwatch, etc.).

[0045] In some embodiments, the processor may further be configured to receive from sensor or sensors 180 a second actual location on rebound unit 100 at which ball 10 engaged rebound unit 100, for example, a corner between inlet 142 and rebound surface 120. In some embodiments, the processor may calculate user performance level based on the distance between the second required location and the second actual location. For example, if the distance is above a predetermined level (e.g., 50 cm) the processor may give the user a low score while if the distance is below another predetermined level (e.g., 10 cm) a high score may be assigned to the user's performance. In some embodiments, the calculated performance level may be presented to the user via the user interface.

[0046] Reference is now made to Fig. 2 which is an illustration of a rebound unit for soccer training according to some embodiments of the invention.

Tunnel 240 may include at least two tunnel inlets 242 and 246 and a tunnel outlet 244. Tunnel 240 may have a cross section larger than a soccer ball's outer diameter (e.g., soccer ball 10). In some embodiments, the shape of tunnel 240 may be such that when base 210 is placed on the ground soccer ball 10 entering either inlet 242 or inlet 246 may directed towards outlet 244.

[0047] In some embodiments, base 110 of rebound unit 100 may have any geometrical shape as illustrated, for example, in Figs. 3A and 3B which are illustrations of rebound units according to some embodiments of the invention. Rebound unit 100 of Fig. 3A may have a base in a shape of a cube and rebound unit 100 of Fig. 3B may have a base in a shape of a cylinder.

[0048] In some embodiments, tunnel 140 may include an adjustable directing element configured to set the exit direction from the tunnel, as illustrated in Figs. 4A, 4B and 5. In some embodiments, rebound unit 100 may further include a connector for connecting two or more bases 110 into a single rebound unit.

[0049] Reference is now made to Figs. 4A and 4B which are illustrations of a directing element and a connector in a rebound unit according to some embodiments of the invention. Directing element 145 may be located or included in tunnel 140 such that a ball 10 (illustrated in Fig. 4B) entering tunnel 140 may be directed by directing element 145 to exit tunnel 140 at a predetermined exit direction (marked with an arrow). The exit direction may be defined as the direction at which the ball is set to exit tunnel 140, for example, with respect to one of the rebound surfaces. In some embodiments, directing element 145 may have a concaved shape (as illustrated).

[0050] In some embodiments, rebound unit 100 may further include a connector 160 to connect at least one additional rebound unit 100.

Adjustable indicator 164 may be controlled manually (e.g., by a coach) or automatically by processor 1120 and/or the processor of mobile device 20. In some embodiments, both adjustable indicator 164 and one or more sensors 108 and 180 of rebound unit 100 may be in communication with and/or controlled by processor 1120 and/or the processor of mobile device 20.

[0069] Reference is now made to Fig. 15 which is a flowchart of a method of training a soccer player according to some embodiments of the invention. In some embodiments, one or more defense player simulation devices (e.g., devices 60, 70, 80, 90 and 91) may be placed on a field, in step 1510, for example, by the player or the coach. The player or the coach may place the defense player simulation devices at locations determined according to a training program.

[0070] In some embodiments, one or more adjustable indicators included in the one or more defense player simulation devices may be adjusted according to game instructions, in step 1520. For example, the coach or the player may shift an arrow to mark from which side to pass the simulation devices or which foot to use for kicking the ball. In another example, the coach or the player may mark by coloring or lighting a portion of the simulation devices indicating with part of the shoe to use for kicking the ball (as illustrated in Figs. 6-8 and 10). In yet another example, the coach or the player may use an application running on a mobile device to remotely adjust the one or more adjustable indicators. In some embodiments, the application may include on option for selecting an order of operation of two or more simulation devices and the adjustable indicators the two or more simulation devices may be lit/operated according to the selected order. It should be appreciated by those skilled in the art that once a player has completed the required task in a first location (e.g., passed the first defense player simulation device from the required side, kicked the ball through a tunnel in rebound a unit, etc.), the next required task may be indicated by one or more indicators located on the same or another device. According to some embodiments, determining that a task has been completed may be by a coach or a player, or by the processor, based on input received from one or more sensors.

[0071] Reference is now made to Fig. 16 which is a flowchart of a method of controlling a soccer training system according to some embodiments of the invention. The method of Fig. 16 may be executed by processor 1120 and/or by the processor of mobile device 20 or by any other processor. A location of at least one of: a ball or a player may be received from at least one sensor (e.g., sensor 68, 108 or 180) located on at least one of: a rebound unit (e.g., unit 100 or 200) and one or more defense player simulation devices (e.g., 60, 70, 80, 90 and 91) included in the training system, in step 1610. In some embodiments, game instructions may be determined to be provided to the player based on the received location, in step 1620. According to some embodiments, the game instructions may include, from which side of a defense simulation device to pass the ball, from which side of a defense simulation device the player should pass, which leg to use for kicking the ball and which part of the shoe, how many defense player simulation devices the user must pass and at which order, to which direction the ball should be kicked, and the like.

[0072] In some embodiments, at least one adjustable indicator (e.g., indicator 64, 74, 84 and 164) located on at least one of: the rebound unit and the one or more defense player simulation devices, may be adjusted to provide the game instructions to the player, in step 1630. The at least one adjustable indicator may be adjusted according to any one of the embodiments disclosed above.

[0073] An example of a training session of a soccer player using system 1000 may include: providing an instruction to the player to pass a first defense player simulation device 60 from the left, by adjusting a first adjustable indicator 64. A first sensor 68 attached to first defense player simulation device 60 may send controller 1100 an indication that the player successfully preformed the task. In some embodiments, controller 1100 may control a second defense player simulation device 60 to present the player instructions to pass the second simulation device 60 from the left while kicking the ball with the right side of the shoe, by adjusting a second adjustable indicator 64. A second sensor 68 attached to second defense player simulation device 60 may send controller 1100 an indication that the player failed to preformed the task. Controller 1100 may present to the player, on a user device, a score (e.g., 50%) for completing only 1/2 of the task and/or presenting the player with additional instructions, using for example, the adjustable indicators 64 on the first and second simulation devices 60.

[0074] While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
