A racquet sports scoring system is provided. The scoring system uses a computerized display and input system to receive scoring changes. In many embodiments, the computerized interface is in communication with a database which records the score in real time, and also records scores of other concurrently-played matches. These match scores, and in some cases video of live matches played at other locations, can be viewed on the same computerized interface on which scores are recorded or on remote devices.

A flexible net system is provided that includes a net having a net first end and a net second end, a net top portion, and a net bottom portion. The system further including a pair of support bases including a first support base and a second support base, each support base including a base bottom portion, a support portion extending upwards from the base bottom portion, the support portion engaging and pivotably securing a control arm thereto, and a base strap having a base strap first end secured to the support portion and a base strap second end secured to the net bottom portion. The system further including a first net support pole and a second net support pole, wherein the first net support pole and the second net support pole are resiliently bendable and coupled between the net and respective support bases, and a plurality primary support ropes.

Systems, methods, and computer-readable media are disclosed for autonomous tennis assistant systems that may automatically determine performance metrics and generate tennis statistics. Example methods include determining, by a device, various performance metrics for users via images captured during gameplay. For example, the device may determine whether a tennis ball landed within, outside, or on a boundary line, whether a point was scored, a ball speed of a tennis ball, topspin of a tennis ball, a type of stroke used to hit a tennis ball, whether a tennis match was won, hitting accuracy of a player, distance moved by a player, and/or other metrics. A base station may be used to provide image data for use by the tennis ball ejection robot from one or more additional vantage points.

A let detection system includes a sensor including an accelerometer attached to a tennis net. The sensor is in wireless communication with an umpire device able to send a message to the sensor, wherein the message causes the sensor to calibrate and begin monitoring for a let. The sensor determines a three-dimensional (3D) vector representing the gravity acting on the sensor as a baseline. When the sensor detects vertical acceleration of the net relative to the baseline and the vertical motion is above a preset threshold, the sensor automatically transmits a let notification message to the umpire device.

A retractable cone net system includes a first net anchor member; a second net anchor member; and a net for stretching between the first net anchor member and the second net anchor member. The first net anchor member is configured to attach to a first cone, and the second net anchor member is configured to attach to a second cone. The second net anchor member includes a net attachment mechanism for attaching one end of the net when in use. The first net anchor member includes a net storage chamber for storing the net when not in use. The first net anchor member includes a net retraction mechanism for retracting the net into the net storage chamber of the first net anchor member when the net is not in use.

An interactive electronic table tennis game is provided that has a table having first and second table portions that are foldable. There are first and second table portions that are structurally the same, and the second table portion has a flat top that is made of a hard material that is clear, transparent, or translucent such that light can pass through the hard material. The flat top is mounted on a frame that defines a plurality of compartments and lights or light emitting diodes that are positioned in the compartments. The frame also supports electronics. The electronics have audio pickups, converter microcontrollers, and a table tennis game computer. When a ball hits the first and second table portions light is emitted by the LEDs in that compartment. This makes the interactive electronic table tennis game fun to play and fun to watch, because everyone can see where the ball impacts.

The present invention proposes a court, which is a half- or full-court in which ball sports, such as soccer (penalty kicks), foot volleyball, volleyball, and basketball (3×3 basketball), can be played. The court allows balls to be automatically and rapidly supplied in the case where it takes time to resume a game, such as a case where a game is replayed or a case where a ball is out according to the characteristics of each type of sport, or in the case where serve-reception practice is required, and also allows balls to be naturally collected and lifted because the court is inclined and allows the balls to be automatically classified according to the types of balls and to be supplied to the court.

A ball net structure arranged to be portable, collapsible, and able to be configured into different arrangements for different nets and/or different sports-related activities. The ball net structure comprising a base structure including at least one support portion, at least one base extension, and at least one base extension hinge, wherein the at least one support portion and the at least one base extension are coupled to the at least one base extension hinge. At least one rod is removably coupled to the base structure and received by a net, wherein the net is adapted to exert a force on the at least one rod causing the at least one rod to exert a force onto said base structure.

The multisport space includes a plurality of different fields for goal sports and net sports. There is a first square or rectangular area for goal sports delimited by a vertical wall. The first goal sports area has a goal sports field in which the goals are vertical and extend from ground level. There is a goal sports field in which the goals are horizontal and placed at a certain height. The panels of the vertical wall form nets for a plurality of net sports fields arranged on either side of the panels of the vertical wall. Extensions of panels, leading from their respective implantation axes, also form nets for net sports fields.
