A portable game includes a lower table forming a circular playing surface and an edge having a diameter D1, an upper table forming a circular playing surface and an edge having a diameter D2, wherein D1>D2. A vertical support member interconnects the lower and upper tables. Cup positioning markers are formed on said first and second table playing surfaces for locating said beverage cups thereon. An elongated barrier assembly extends vertically above said playing surface and horizontally bisects the upwardly facing playing surface. The vertical barrier is operative to define discrete opposed team play areas enabling a plurality of teams to play simultaneously on opposed sides of said barrier and to prevent horizontal travel of ping pong balls between opposing team play areas. The barrier is supported by at least one vertically elongated support stanchion slip-fit within the playing surfaces to enable selective removal and insertion thereof.

An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.

The present disclosure provides a rotation estimation device including an acquisition section and a rotation estimation section.

A stroke decision device 30 includes an acquisition section 31 configured to acquire state information including a position, a velocity, and a rotational velocity of an incoming ball, and a stroke decision section 32 configured to decide a stroke condition including a position, a velocity, and an orientation of a striking implement at a time point when hitting back the ball toward a target arrival position, based on the state information for the ball and the target arrival position when hitting back the ball with the striking implement.

A portable game includes a lower table forming a circular playing surface and an edge having a diameter D1, an upper table forming a circular playing surface and an edge having a diameter D2, wherein D1>D2. A vertical support member interconnects the lower and upper tables. Both playing surfaces include an inner circular hub line extending about the center of the respective playing surfaces, and a plurality of radially directed rays formed on the respective playing surfaces. Each ray is circumferentially equally spaced from each immediately adjacent ray, wherein each pair of adjacent rays defines a trapezoidal play segment extending between the edge and hub line. An outer cup positioning marker is centrally formed in each play segment at a common radial distance from the edge, and an inner cup positioning marker is centrally formed in each play segment at a common radial distance from the hub line.

An omnidirectional system (1) is described, for expelling and collecting balls, adapted to reproduce a real playing and/or training dynamics, such system (1) being equipped with at least one closing element (8) connected to at least one expelling device (2) of the system (1) arranged orthogonal to the expelling device (2) when expelling at least one ball from the system (1), the ball bouncing on an upper surface of the closing element (8) going towards at least one user; and with at least one net element (7) of at least one collecting element (3) of the system (1).

An exemplary embellishment is configured for use with sports or recreational equipment having a flat/planar surface. The embellishment is in the form of a planar sheet including a front surface and a rear surface opposite the front surface. The planar sheet is sized and shaped to correspond to a size and shape of the planar surface of the equipment. The front surface comprises at least one ornamental marking and/or at least one functional marking. Each functional marking relates to performance of a sport or recreational activity corresponding to the equipment. The rear surface has disposed thereon an adhesive configured to removably secure the planar sheet to the planar surface.
