A non-spherical training ball for training a pitcher to throw a ball with proper technique is provided. The training ball has a hollow body having a spherical surface forming a spherical cap having a height greater than the radius of the sphere from which the spherical cap is formed and a substantially planar surface forming the spherical cap plane. Sidewalls form the hollow cavity of the hollow body, the sidewalls have a spherical surface sidewall portion forming the spherical surface of the hollow body and a planar surface sidewall portion forming the substantially planar surface of the hollow body. The sidewall thickness of the planar surface sidewall portion has a thickness greater than the sidewall thickness of the spherical surface sidewall portion.

The present disclosure provides a new and innovative system for sport design, tracking, and sharing. The system includes a set of wireless components in communication with a computing system. The computing system may include a graphical user interface, and at least in some instances, communicates over a network with an external system such as a social media platform. Through the graphical interface, a user may program rules to a sport into the wireless components. The user or users may perform the sport with the programmed wireless components, which analyze the actions performed according to the programmed rules. The analysis and other data collected by the wireless components may be reviewed by the users after playing the sport. Furthermore, the data collected and the rules programmed into the wireless components may be shared online to the external system for rating and ranking by an online community.

This disclosure relates to a ball comprising a core and a porous structure encompassing the core. The porous structure comprises a plurality of perforations in its outer surface, which are connected with a plurality of hollow confined spaces within the porous structure allowing a liquid to be at least partly absorbed by the hollow confined spaces upon contact of the ball with the liquid. A shell with shell perforations encompasses the porous structure. The ball comprises control means for controlling the absorption of liquid by the ball and the release of absorbed liquid from the ball.

An exercise ball with internal weight with two shell portions, at least one internal plate weight, and at least one strap with engaged with the plate. The shell portions have at least one internal plate relief, and at least one external relief formed on an outer surface of the shell to allow access to an inside of the shells. The plate has at least one alignment aperture for retaining the plate in the internal plate relief of the shell portions, and at least one connection area comprising a slot on the plate to allow the attachment to slide therethrough to retain the plate in the relief of the shell portions. The strap extends outside of the shells through the at least one external relief when the two shells are connected together around the plate.

A method for tracking performance of player including determining global direction of magnetic field at first court and computing first court specific data; providing rotation for rotating apparatus about spin axis via player, wherein rotating apparatus comprising XYZ-magnetic field sensor; measuring plurality of magnetic field values as function of time when rotating apparatus is rotating about spin axis; computing magnetic field component of magnetic field in direction of local body co-ordinate of spin axis of rotating apparatus; determining direction of spin axis using computed magnetic field component of magnetic field and determined global direction of magnetic field; determining player specific data comprising angle of spin axis with respect to horizontal ground plane and angle of shot direction with respect to horizontal component of spin axis; and calibrating and storing first court specific data and player specific data to track performance of player at first court.

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a server processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the server processor with time stamps. The server processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A device for training a person to throw a ball includes a body. The body defines a first planar surface, a second planar surface, and a curved surface. The first planar surface is defined at a first end of the body. The second planar surface is defined at a second end of the body. The curved surface is defined between the first planar surface and second planar surface. The device has a center of mass that is located outside of the geometric center of the device.

A football device includes an outer skin and an inner bladder to be inflatable and substantially resemble and perform like an actual football. The football device includes a sensor unit that can sense various performance metrics and wirelessly communicate data to another device such as a mobile device. To maintain a feel and performance as close to an actual football as possible, a battery powering the sensor unit is wirelessly recharged.

A cue ball used for practice and play in pool or billiards. The cue ball is made with a plurality of concentric sphere layers or shells starting with a centermost opaque ball, followed by two or three spheres of differently colored semi-transparent polymer resins; then an outermost clear layer of polymer.
