Provided is a method for manufacturing an exercise ball which is made by using a pasted ball such as a soft leather ball and which has a lower impact value compared to a conventional yarn-wound ball. The exercise ball comprises a spherical hollow rubber bladder (2) in which compressed air is sealed, and a yarn-wound reinforcement layer (3) formed by evenly winding a filament yarn around the surface of the rubber bladder, wherein the exercise ball is characterized in that nylon filament yarn, obtained by hard twisting two 30-50 denier nylon filaments 1-a, 1-b in a single-direction twist is used as a winding yarn (1).

A generally spherical basketball defining a center point and including a carcass having an outer surface and a cover assembly positioned over the outer surface of the carcass. The cover assembly includes at least one cover panel. The cover panel has an outer surface including a valley base surface and first and second sets of spaced-apart projections. Each of the projections of the first and second sets of spaced-apart projections include first and second outermost surfaces, respectively. The first set of projections have an average height measured in a radial direction from the center point within the range of 0.2 to 2.0 mm from the valley base surface to the first outermost surface. The second set of projections have an average height measured in a radial direction from the center point within the range of 15 to 175 μm from the valley base surface to the second outermost surface.

The present disclosure relates to a system for supporting a movement of a person with an object. The system comprises a detection device configured to detect an actual state of the object. The system also comprises a sensor arrangement, which is configured to record at least one physiological parameter of the person. The system also comprises a determination device configured to determine a target state of the object based on the detected physiological parameter. The system furthermore comprises a display device configured to display an indication when the actual state differs from the target state. The present disclosure further relates to a method and a computer program product.

A grip assessment device includes a support structure having a periphery, a cover positioned around the support structure and configured to define a grip surface, and a plurality of sensor elements disposed along the periphery of the support structure, each respective sensor element of the plurality of sensor elements being configured to generate an output signal indicative of force applied to the grip surface at the respective sensor element. The plurality of sensor elements are distributed across the grip surface such that the output signals from the plurality of sensor elements are collectively indicative of a grip profile along the grip surface, the grip profile providing grip position data and grip magnitude data correlated with the grip position data.

A system for lighting a volleyball court has four corner light assemblies, two side center light assemblies, and four mid-court light assemblies. Each corner light assembly has an upper light fixture adapted to emit light outward and downward at a level generally below a player's eye level and a lower light element mounted in a manner to emit light outwards and upwards. Each side center light assembly has two lower light fixtures adapted to emit light outward and downward at a level generally below a player's eye level and an upper light assembly adapted to emit light outwards and upwards at a level generally above a player's eye level. Each mid-court light assembly has a light fixture adapted to emit light outward and downward at a level generally below a player's eye level. By ensuring that no light is emitted at a player's eye level, glare is significantly reduced.

The present disclosure relates to a panel for ball game ball and a ball game ball including the same, and more particularly, to a panel for ball game ball and a ball game ball including the same capable of facilitating the coupling between adjacent panels and improving an adhesive strength between the panels when attaching a plurality of panels forming a surface of the ball game ball.

An apparatus for a ball stowable support is provided. The apparatus includes a frame, an elastic cover secured to the frame, and at least one leg supporting the frame. Each leg of the at least one leg has an opening. The opening is configured to retain a ball.

A generally spherical basketball defining a center point and including a carcass having an outer surface and a cover assembly positioned over the outer surface of the carcass. The cover assembly includes at least one cover panel. The cover panel has an outer surface including a valley base surface and first and second sets of spaced-apart projections. Each of the projections of the first and second sets of spaced-apart projections include first and second outermost surfaces, respectively. The first set of projections have an average height measured in a radial direction from the center point within the range of 0.2 to 2.0 mm from the valley base surface to the first outermost surface. The second set of projections have an average height measured in a radial direction from the center point within the range of 15 to 175 μm from the valley base surface to the second outermost surface.

Improved pitching machines capable of providing accurate, repeatable, and various pitches for training or simulation purposes (e.g., batting and catching). The pitching machine of the present invention may be operable to deliver pitches that each have a different predetermined trajectory, location, velocity (speed to target), and rotational velocity with repeatable precision and accuracy. Additionally, the pitching machine may be programmable and capable of simulating a pitch sequence, as thrown by a pitcher in a game situation, which provides a novel and effective tool for training batters.

A system for refereeing a sports match including a portable processing device for compiling data associated with the sports match and eyeglasses including data display means for displaying the data associated with the sports match to a wearer of the eyeglasses.
