A ball, and in particular a baseball or softball, including one or more sensors such as accelerometers and/or inertial measurement units, and systems and methods using the same to improve a pitcher's pitching performance are described herein. In some embodiments, the ball may include one or more inertial measurement units and/or accelerometers capable of monitoring motion of the ball while it is thrown. Various types of pitches may be selected, and in response to the inertial measurement unit(s) and/or accelerometer(s) detecting certain parameters corresponding to a selected pitch, one or more indicators may be caused to perform an action. For example, one or more illuminating elements located on the ball may turn a first color in response to detecting parameters corresponding to the selected pitch.

A method of providing feedback for a piece of cue-sport equipment, a cue ball or cue stick, during a game play first collect spatial positioning and orientation data from a plurality of measurement sensors that is integrated into the cue-sport equipment. Then, the collected data is analyzed to generate a virtual movement model of the cue-sport equipment as the virtual movement model includes a calculated impact force diagram, an animated travel path, and a calculated absolute orientation for the cue-sport equipment. Then, the player can view the virtual movement model through an external computing device to improve their cue-sport skills effectively and efficiently.

A puck includes a main body having a first portion and a second portion securely attached to form a generally cylindrical shape with an internal cavity. One or more energy absorbing components are positioned within the internal cavity. A weight component is positioned adjacent to the one or more energy absorbing components within the internal cavity. The weight component is sized to move in a vertical direction and deform the one or more energy absorbing components within the internal cavity in response to movement of the puck.

A throwing and/or catching toy includes a generally elongated spheroidal body defining a longitudinal axis. A length of the body is longer than an equatorial diameter. A lift-generating wing is non-movably attached to the body near and/or at a center of the wing. At least one finger hold extension extends from a distal end of either a left or right wing portion. The finger hold extension is configured to allow a user to throw the toy in a discus-launched manner and the body is configured to be caught by the user. The lift-generating wing may be made as an injection molded, polymer wing. A manual adjuster may be associated with and controlling the shape of a horizontal stabilizer. A front end of the elongated body may be a resilient foam having a Shore A durometer hardness equal to or less than 25.

A golf ball including a spherical body, first regions, and second regions. The spherical body includes a core layer and a cover layer made from a synthetic resin covering the core layer. Dimples are formed in a surface of the cover layer. First regions that are electrically conductive are formed on a surface of the spherical body. The first regions are formed on a spherical surface having a center of the spherical body as a center. The first regions are positioned at six vertices of an imaginary regular hexahedron such that the vertices are positioned on the surface of the spherical body and, thus, six of the first regions are formed. The second regions are formed in areas of the surface other than where the first regions are formed. The second regions have a radio wave reflectance lower than that of the first regions.

Embodiments relate to a concept for determining a transit of a movable object through a detection area within a detection plane. At least one exciter antenna provides an exciting electromagnetic field. The exciting electromagnetic field or at least one spatial component thereof has a field strength above a field strength threshold in the detection area. The exciting electromagnetic field is capable of exciting the movable object to emit an electromagnetic response signal comprising information on a position of the movable object. At least one sensor antenna comprising a magnetic core receives the electromagnetic response signal. The at least one magnetic core is positioned in a region of the exciting electromagnetic field where the field strength of the exciting electromagnetic field or the at least one spatial component thereof is below the field strength threshold.

Cue sports tables are provided with associated automated sensor and positioning assemblies. This permits competitors to play each other on separate tables. The tables automatically sense ball positions on one table and communicate that to a positioner associated with another table. That positioner then automatically drives balls on that other table to a mimicking position. These systems also permit a shot to be replayed if desired.

In a measurement unit, a primary acceleration sensor is fixed at the center of gravity of a flying object or at a position within a certain error range from the center of gravity. A secondary acceleration sensor is fixed inside the flying object so as to be spaced from the center of gravity of the flying object. In a measurement apparatus, an acquirer acquires a primary acceleration measured by the primary acceleration sensor during flight of the flying object and a secondary acceleration measured by the secondary acceleration sensor during the flight of the flying object. An estimator estimates a spin rate per unit time of the flying object from the acquired primary acceleration and the acquired secondary acceleration using maximum likelihood estimation.

A system, method and device for a sport game are provided. The game utilizes a plurality of play articles, at least three stations cum goals or targets, a playground, a game controller device and a display device. The game is played by individual participant or participants wherein the rules of the game maintain a familiarity with an ancient puzzle game and is based on a mathematical formula of logarithmic scale where the play articles are moved around the stations by play participants to accrue points or goals and where the devices are incorporated with identification, tracking, data transmission, data processing, determination and data display capabilities to monitor and manage the game. The game provides physical, skill and cerebral challenges and is applicable to a plurality of normal sports wherein goal or target shooting is primal; the game can be played indoors or outdoors, for fun, exercise, training of sport skills, light or serious competition.
