An athletic training device for teaching a crossover dribble skill comprised of an arc member coupled to weighted bases where the device is self-righting. The training device teaches players that the crossover dribble skill is low and has a significant horizontal component by passing the basketball underneath the arc member. The training device is self-righting due to the curved lower surface of the weighted bases as well as the weighted bases having a top and bottom chamber where only the bottom chamber is filled.

A game-court-surface projector system and method providing projection of a variety of projected images upon a game court or half court, showing proper boundaries and lines for various games and levels of play, allowing multiple uses for one game court or half court, allowing the development of new games or variants, and allowing improved training and practice by using accurate boundaries and lines for different games and levels of play, and using other projected images.

An athletic training system (200) has a data recording system (202) and a data engine (204). The data recording system (202) is configured to record an athletic competition event. The event may have a first team of players competing against a second team of players. The data engine (204) is configured to receive data associated with the recorded athletic competition event. The data engine (204) processes the data and displays the data as a replay of the event in animated form.

A method can include determining physical characteristics of a trainee, adjusting a target zone based on the physical characteristics, adjusting one or more parameters of a delivery device based on the physical characteristics, projecting an object toward the target zone along a trajectory, and scoring a performance score of the trainee to track the object along a portion of the trajectory. A method can include projecting an object toward a target zone along a trajectory, a trainee attempting to impact the object at an appropriate location with a desired impact location of a sport tool, capturing imagery that contains the object at the appropriate location and the desired impact location of the sport tool, determining horizontal and vertical distances between the desired impact location and the object arriving at the appropriate location, and scoring a performance based on the horizontal and vertical distances.

A method can include projecting one or more objects along one or more pre-determined trajectories toward a target zone, with each having a diameter less than a diameter of a regulation table tennis ball, the trainee attempting to prevent the one or more objects from entering the target zone and scoring the ability of the trainee. A method can include displaying a first video to a trainee that explains setup for a delivery device, setting up the delivery device based on the first video, projecting an object along a pre-determined trajectory toward a target zone proximate the trainee, wherein the object has a diameter that is less than a diameter of a regulation table tennis ball, and scoring an ability of the trainee to interact with the object at the target zone.

A multi-directional expandable modular agility exercise ladder has spaced rows of two part paired rungs having overlapping ends joined to each by a pivot post forming a variable angle chevron prow. Outer ends of the paired rungs are interlocked to two parallel spaced bands to complete the ladder. A hook and loop pad interlock is used. Alternately, spaced key holes extend through the bands with the outer ends of the rungs having downwardly extending retainer poles secured in a respective key hole. Alternately, releasable spring clamps hand movable along the band length secure rung ends to the bands.

The present disclosure is directed to a system for sensor-based objective determination. In general, sensor data may be used to render objective determinations that were not previously possible due to the unavoidable subjectivity of human-based officiating systems. For example, at least one device may be configured to make objective determinations during the course of a sporting event. Data collection circuitry may receive data from sensor devices coupled to players, equipment, playing surfaces, etc. Data analysis circuitry may categorize the data and input the data into a model to determine if an infraction occurred. For example, categorization may involve determining a type of infraction that may have occurred based on the sensor data. The model may then be selected based on the type of infraction, the model being developed utilizing prior sensor data, rules for the sporting event, etc. Output circuitry may generate a notification based on the infraction determination.

The disclosure is directed to systems and methods for providing a user with key performance indicators of a basketball player relating to accuracy, precision and improvement. Specifically, the disclosure is directed to a system of sensors coupled to a basketball backboard adapted to provide an accurate tracking of a shot in a given three-dimensional space and extract features manipulated to yield key performance indicators based on establishing whether, how often and where the ball center passes the rim plane at a sub-cm resolution over a period of no more than 200 msec.

Implementations of a time-out synchronized system are provided. In some implementations, the time-out synchronized system comprises a coach's device and a referee's device (“referee's wristband”). In some implementations, a method of using the time-out synchronized system comprises a coach using the coach's device to make a timeout call and a referee using the referee's wristband to be alerted and/or informed of the timeout call during an organized sports event, such as a basketball game.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.
