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.

Soccer balls, volley balls and the like are provided with interior reinforcing patches disposed over the stitched seems to prevent thread breakage, seam separation and water incursion while at the same time enhancing the softness and durability of the ball's structural panels.

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.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A basketball training system includes a server computer and a basketball training machine. The server computer executes a workout module that manages operation of a graphical user interface that presents a graphical representation of a portion of a basketball court and receives user inputs that define a workout program that includes selected ball delivery locations relative to the visual representation. The basketball training machine receives the workout program and delivers basketballs to the selected ball delivery locations.

A ball hitting practice device includes a shaft having a target at a distal end, a grip at a proximal end, an accelerometer, a microprocessor, and a way of providing feedback to a person hitting the target. A ball hitting practice system includes a ball hitting practice device and a computing device wirelessly communicating with the ball hitting practice device. A method for practicing ball hitting involves striking the target of a ball hitting practice, transferring timed acceleration data to the computing device, correlating ball hitting parameters with a training condition and displaying the correlated ball hitting parameter in a display.

An apparatus for a ball stowable support is provided. The apparatus includes a frame, an elastic cover secured to the frame, and at least one leg supporting the frame. Each leg of the at least one leg has an opening. The opening is configured to retain a ball.

A system for illustrating the flight of a sports ball includes a radar, an imager, and a controller. The imager is configured to image a moving sports ball. The controller is configured to (i) receive, from the imager, an image including the moving sports ball, (ii) receive, from the radar, radar data associated with the moving sports ball, (iii) determine, from the radar data, a portion of a trajectory of the moving sports hall, (iv) alter the image to illustrate the portion of the trajectory relative to the moving sports ball, and (v) output the altered image.

A system for lighting a volleyball court has four corner light assemblies, two side center light assemblies, and four mid-court light assemblies. Each corner light assembly has an upper light fixture adapted to emit light outward and downward at a level generally below a player's eye level and a lower light element mounted in a manner to emit light outwards and upwards. Each side center light assembly has two lower light fixtures adapted to emit light outward and downward at a level generally below a player's eye level and an upper light assembly adapted to emit light outwards and upwards at a level generally above a player's eye level. Each mid-court light assembly has a light fixture adapted to emit light outward and downward at a level generally below a player's eye level. By ensuring that no light is emitted at a player's eye level, glare is significantly reduced.
