A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

A system is disclosed that includes a ball-throwing machine included within a first housing, a controller communicatively coupled to the ball-throwing machine and included within a second housing different than the first housing, a camera, and a non-transitory storage medium having stored thereon logic, the logic being executable by one or more processors to perform operations including: receiving information associated with a selection of a first training drill from the controller, responsive to receiving the information associated with the selection of the first training drill, causing the ball-throwing machine to impart motion to one or more balls in accordance with the first training drill, receiving multimedia data of a player captured by the camera, and performing a player recognition procedure to locate the player within the multimedia data.

A sports ball easy loading and unloading apparatus assists a user loading, unloading, and sorting balls in a container by selectively elevating the container holding the balls, which minimizes stooping repeatedly to access the sports balls. The apparatus provides a first container configured to contain sports balls. The first container is disposed inside a second container having a larger diameter. The first container can elevate and lower in relation to second container. A spring-loaded elevator is disposed inside the second container, and beneath the floor wall of first container. The spring-loaded elevator comprises a spring that biases to expand, and turntables configured to lock the spring at desired positions. In this manner, the spring-loaded elevator enables selective elevation, lowering, and positional locking of the first container for easy loading/unloading of balls. A user can also sit on a lid atop the first container when fully compressed inside second container.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

The present disclosure involves systems for applying finishing treatment to balls. The system includes an arm that transports at least one ball through a plurality of stations. A first station includes a first actuator, which permits introduction of a ball into the arm. A second station includes a buffer, which buffs the surface of the ball and rotates the ball in place relative to the arm, a spray nozzle configured to apply treatment to the ball, and a camera configured to capture images of the ball. A third station includes an inspection camera that captures inspection images of the ball and a rotating plate configured to rotate the ball in place relative to the arm. A fourth station includes a second actuator, which ejects the ball from the arm.
