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 system and method for measuring motion properties of a movable object, such as a sporting device, wherein the movable object has an embedded magnetized unit creating a magnetic field. A measurement device, having a first magnetic field sensor positioned a known distance away from a second magnetic field sensor, is positioned in the vicinity of the movable object's trajectory, whereby the first and second magnetic field sensors output signals when the movable object passes within their respective proximities. A control module, that is responsive to the output signals created by the magnetic field sensors, is configured to record the times of output signal events. The control module is further configured to calculate motion properties, such as the speed and rate of spin, of the movable object based upon the recorded times of various sensor output events and the known distance between the first and second magnetic field sensors.

A curling game apparatus including a main body, a curling table provided on the upper end of the body, and a curling ball formed in the perfect spherical shape as a rigid body and moved on the curling table. The curling table includes an upper plate provided along a bottom surface and a periphery of an upper end of the main body, a plurality of cushion bars provided inside the upper plate, and an upper plate surface portion horizontally provided on a surface of the upper plate. The upper plate surface portion is provided with at least one hit line for hitting the curling ball and at least one target to which the curling ball starts from the hit line by hitting to reach. The curling ball is reflected by the cushion bars to move to the target while the curling ball rotates with the hitting point thereof.

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

This disclosure includes hockey pucks and methods of making hockey pucks. Some pucks include a shell having an upper shell member and a lower shell member coupled to the upper shell member to define a cavity and a ballast member disposed in the cavity such that at least a portion of the ballast member is translatable relative to the shell. Some pucks include a resilient material disposed in the cavity and configured to resist translation of the ballast member in at least one direction relative to the shell. Some pucks include a cylindrical outer housing surrounding the shell. Some pucks include first and third substantially cylindrical members, a second member, a first plurality of fasteners to couple the first member to the second member independently of the third member, and a second plurality of fasteners to couple the third member to the second member independently of the first member.

An apparatus for training athletes having two supporting structures. The first structure has a base that can rest on a surface and walls that extend upward from the base to an upper end, defining an interior space. The walls incorporate a bar connector above the base designed to connect to and support one end of a bar. The walls have supporting elements above the base and below the upper end of the walls. The second structure has walls that are configured so that the lower end of the walls can engage the supporting elements of the first structure so that the second structure is supported by the first structure above the supporting elements. The second structure has a bar connector at the same height as the height of the bar connector of the first structure configured to connect to and support the other end of the bar.
