An improved basketball court that provides a safe environment for the players in which to play the game and officials to manage gameplay. The disclosed updated court exhibits increased dimensions in length and width, four-point shooting locations, a full three-point arc shot line, and increased distance behind the basket and along the baseline.

A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and contains multiple variable-color cells (404), each extending to a part (406) of the zone. The cells normally appear along their parts of the zone as a principal color. Each cell that meets cellular threshold impact criteria in response to an object (104) impacting the zone at an object-contact area (116) temporarily becomes a criteria-meeting cell that temporarily appears along its part of the zone as changed color materially different from the principal color. A group of less than all the cells usually constitute criteria-meeting cells. The surface parts of the criteria-meeting cells form a print area (118) that closely matches the object-contact area in size, shape, and location. The color-change capability helps in making in/out calls in sports such as tennis.

According to some implementations a floor is provided that comprises a substrate having a top surface and a groove formed therein. The groove has an open end located at the top surface of the substrate. The groove further includes a bottom wall and side walls with the bottom wall located a first distance below the top surface of the substrate. The groove extends along a length of the substrate. A light diffusing optical fiber or other lighting means is supported inside the groove by a transparent or translucent fiber support that spaces the light diffusing optical fiber or other lighting means a distance away from the bottom wall, side walls and open end of the groove. According to some implementations the walls of the groove or the outer surfaces of the fiber support are provided with light reflectors to enhance the propagation of light toward the open end of the groove.

The present utility model relates to the technical field of martial arts, and more particularly to a ring which is laterally surrounded by a rigid and transparent material. The proposed design aims to improve viewing for spectators and television viewers by allowing viewing, filming and photography from any angle without any obstructions, such as fencing, ropes or nets, which impede a clear view of a martial arts event. The present solution is also intended to benefit the dynamics of a fight by reducing clinch time and preventing a fighter from holding onto the fencing that currently surrounds a ring. In addition, there is the possibility of projecting images onto the outer side of the ring. In this case, spectators and television viewers will be able to view information such as, inter alia, competitor profiles, replays of fights, and sponsorship advertisements.

An arrangement, a computer system, and/or a method for playing a game include a playing area, a first set of scoring structures arranged at a perimeter of the playing area and that are active throughout the game, and a second set of scoring structures arranged at the perimeter of the playing area and that are active only during penalty periods of the game, where each pair of adjacent ones of structures of the first set is separated by one of the structures of the second set.
