A lacrosse training ball that is made up of a shell that defines an enclosure having an interior volume is disclosed. The shell includes a plurality of pads connected along a plurality of seams sewn with a thread having a finishing knot. The interior volume is substantially occupied by a filler that includes a mixture of a first material and a second material.

A pitch training ball includes a center portion, a first cap, and a second cap. The center portion is opaque and has a first planar surface at a first end thereof, and a second planar surface at a second end thereof opposite to the first end. The first cap portion has a first base that is adjacent to the first planar surface. The second cap portion has a second that is adjacent to the second planar surface. The first cap, the center portion, and the second cap cooperate to define a baseball shape. The first and second caps are transparent to translucent.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

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 smart ball (100) comprising: an inner sphere portion (12) consisting of a cork like material and an outer sphere (19) that ensconces said inner sphere, said inner sphere further comprising: a cylindrical cavity (14), located substantially at the core of said ball, said cavity formed by drilling into said cork from an operative top side; a sensor assembly (16) placed in the centre of said cylindrical cavity along a reference plane defined by a locus of points wherein said points being collinear points running from a first end of said seam (18) to a second end of said seam, thereby ensuring that orthogonal measurements of said sensor assembly being aligned with orthogonal axes of said ball; and a charging port on said seam, said charging port connected to a battery placed in said cylindrical cavity and said battery connected to said sensor assembly.

A luminous safety ball including an inner glowing body and a foam sphere covering the inner glowing body is provided. The inner glowing body is not a perfect sphere, the foam sphere has a non-uniform thickness, and light emitted by the inner glowing body passes through the foam sphere and permeates through a surface of the foam sphere to form light with different brightness thereon.

A sports training ball is disclosed that is made up of a shell having an embossed design that defines an enclosure having an interior volume substantially occupied by a filler that includes a mixture of a first material, a second material, and a third material.

This invention is associated with the sport of cricket in particular but not limited to and applicable to other sports and games as well where a ball is used to play. The invention relates that when a cricket ball having combinations of magnets inside with two different leathers (materials) or a combination of multi-leathers (materials) on the two hemispheres, is delivered by a bowler at a speed, an inherent swing is obtained, which is proportional to the difference in the resultant densities on the two hemispheres of the ball. The invention is aimed at providing a technology by which an inherent swing/drifted spin in the delivered ball is inevitably established which is irrespective of any seam positioning, other bowling skills, surrounding and pitch conditions.
