A recreational/sport apparatus comprises a playing field, on which a target is arranged protruding from a surface of the playing field, and a ball adapted to be shot toward the target. Conveniently, the apparatus comprises means apt to perform the reconstruction of the trajectory of the ball, those means comprising at least one first camera and at least one second camera apt to simultaneously acquire a plurality of first images and second images, respectively, of the ball, and a central unit which receives the first and second images by means of data reception/transmission means and which processes those first and second images in predetermined consecutive time-intervals, the central unit calculating the two-dimensional position of the ball in each of those first and second images, so as to determine, at each time-interval, the three-dimensional position of the ball by comparing those two-dimensional positions, wherein the target is divided into a plurality of target areas and the central unit is apt to recognize a coordinate at which one of the target areas is intersected by the trajectory of the ball.

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.

Systems and methods for providing a running track having a reinforced base using post-tensioning are provided herein. In one exemplary configuration, the track comprises a reinforced concrete slab base that is poured over and around post-tensioning cables suspended therein. The post-tensioning cables include transverse cables that extend transversely across the base, and lengthwise cable structures extending lengthwise through the base. Each lengthwise cable structure includes a series of individual segments that are joined end-to-end to form respective continuous loops and are individually tensioned. The lengthwise cable structures thus exert compressive forces on the base that are continuous and uninterrupted about the circumferential length of the track. Moreover, the lengthwise cable segments are joined/tensioned from within voids initially formed within the concrete base and, after tensioning, these voids are filled with concrete to provide a concrete base having a uniform top surface that can also be covered in a running surface.

Trampoline systems containing at least one platform that extends over and above adjacent trampoline jumping surfaces is disclosed. Methods of making and using trampoline systems containing at least one platform that extends over and above adjacent trampoline jumping surfaces are also disclosed.

A ball tossing game apparatus includes a playing court defined by a pair of longitudinal lines and a pair of lateral lines. The playing court is divided into two equal halves by a central line and each half of the playing court includes a playing zone. The tossing game apparatus further includes a bar assembly disposed on the playing court which includes a pair of vertical bars arranged at either side of the central line extending vertically upwardly from the playing court; and at least one crossbar arranged horizontally between the pair of vertical bars and arranged above and substantially parallel to the central line of the playing court. A ball is provided for two or more players to toss back and forth over or through the at least one crossbar.
