A sports court can include a set of modular floor panels or tiles that are interconnected with each other and that have material compositions configured to provide increased friction when a ball or other game piece comes into contact with the top surface of the panels or tiles. The sports court can be used to decrease the speed or otherwise affect bounce behavior of a game ball as compared to a concrete slab or similar underlying surface on which the floor panels are positioned, thereby giving the court performance characteristics more similar to a conventional court used for ball sports such as tennis and pickleball and that are improved as compared to conventional rigid floor tiles. The material compositions can include rubberized or elastomeric materials with coefficients of friction measured using standardized testing procedures.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A ring for a fighting sport has a circular fighting area defined by a plurality of circular fence rings that are held up by posts. Shock absorbers connect the fence rings to the posts. Position markers are provided to indicate the starting positions of the participating fighters at certain points during the bout.

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.

A ball bouncing game includes a vertical surface and a playing field comprising a first section and a second section each having a respective first player and a second player standing therein. A ball is provided that is thrown by a third player. The ball is bounced against the vertical surface thereby facilitating the ball to travel toward one of the first section or the second section of the playing field. The first player and the second player attempt to catch or deflect to inhibit the ball from landing in the first section or the second section. The ball scores a game point for the third player when the ball lands in either of first section or the second section after the ball is bounced off of the vertical surface.
