An overcap for a container for storing at least one tennis ball, the container extending along a longitudinal axis and having an open end. The overcap includes a body adapted for removably attachment to the open end of the tennis ball container. The body includes a peripheral rim for engaging an outer surface of the container at the open end, and a lip projecting from the peripheral rim toward the longitudinal axis. The peripheral lip extends over a portion of the open end of the tennis ball container. The lip defines a first opening.

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.

A sports projectile delivery system may control the operation of a launcher to cause an American football or other sports projectile to be delivered to a target location on a field. In some aspects, the system can track player movements on the field, e.g., through the use of a tracking device mounted on the player, enabling the ball etc. to be launched to a player in anticipation of where the player will go. The system may include additional customization and/or logging options, e.g., permitting a player to designate a body position (e.g., above the head or near the knees) for delivery of the ball, designate a speed or hang time for delivery, or provide player data and analytics to an online or otherwise connected database.

A ball supply device includes rubber tee on which golf ball is safely mounted; a main body which is spaced apart from the rubber tee; a loading movement plate that is provided in an upper portion of the main body to partially seal the upper portion of the main body; a safe mounting guide portion that rotates on the front side of the main body and guides the golf balls released to the release hole to the rubber tee; a ball hitting portion that is rotatably provided on the front side of the main body to be rotated by the golf ball supplied to the safe mounting guide portion; a ball sensing portion that has one end located on the lower portion of the rubber tee; and a protective cover portion that surrounds the ball sensing portion.

A dispensing assembly includes a cradle above for supporting and dispensing a plurality of balls. The dispensing assembly also includes an output ramp below. The dispensing assembly also includes a guide rail with a spiral section extending downwardly from the cradle to the output ramp. A receiving assembly includes an input ramp below and a cup above. The plurality of balls are positioned in the cradle for being fed by a player down the guide rail, down the output ramp, and hopefully, up the input ramp into the cup.

The invention is that of a lacrosse ball collection apparatus fabricated from materials such as plastics, metals and fabrics. The apparatus comprises a fabric which when in its open position forms a substantially triangular horizontal surface capable of fitting inside a lacrosse goal. When lacrosse balls are shot into the goal, they collect on the fabric. The apparatus is foldable at a front joint and comprises a spout located behind the front joint and in close proximity thereto, such that the apparatus may be used to carry the balls to a collection receptacle, where they may be poured out of the spout into the receptacle for reuse. The apparatus is further foldable at two side joints such that an apical joint is foldable toward the front joint and two front member segments are foldable inward to render the apparatus in a compact, closed position suitable for storage in small spaces.

A basketball training apparatus includes a shot completion sensor, a condition sensor, and a computer. The shot completion sensor determines whether a shot goes through a basketball hoop. The condition sensor senses a physical condition of a basketball shooter. The computer is in communication with the shot completion sensor and the condition sensor, and has a processor for calculating shot completion percentage as a function of the physical condition.

A ball picking robot and a ball unloading method using the same. The ball picking robot includes a chassis, an L-shaped hanging lug, a ball storage frame, an electric push rod disposed on the chassis, a baffle disposed on the chassis, a bracket disposed on the chassis and a drive motor for driving the electric push rod to move. A movable end of the electric push rod is connected with one end of the L-shaped hanging lug, the other end of the L-shaped hanging lug is connected with a side of the ball storage frame, and a camera is disposed on the bracket.

A sports ball carrier is configured to fit inside a storage bag with ball rackets. The carrier may store sports balls in a substantially planar array that is one sports ball thick, and the width of the carrier may taper along its length generally simulating a racket form factor. A sports ball entry port may be provided for ball collection in a manner similar to a conventional ball hopper.
