Abstract: A computer network extends around all the holes of a golf course including a series of interconnected display terminals that can display the real time scores of all players on the course at any time. They may also be equipped with printers for generating hard copies of scores. The terminals are provided with transceivers for two-way radio communication with transceivers in portable player's units carried by each of the players. Each player's unit is provided with a unique transmittable code signal that identifies the unit to the system. Before starting play, a player's identity and the code of the player's unit carried are registered in the system, as well as the team or foursome he is playing with. Before each stroke, a player actuates his unit, which sends a coded radio signal to the nearby terminal. The terminal identifies the player by the code, adds one stroke to his score, and transmits to all players on his team, through their player's units, an audible signal so that honest score keeping is insured.

Abstract: A portable golf putting apparatus includes a simulated grass carpet that can be rolled up in compact sections without interference from any cups. The carpet is unrolled and sections joined together with flat seams that do not interfere with smooth rolling of the ball. Cups are installed at selected locations on the carpet surface. The cups simulate holes in the green by their action but they do not actually descend below the carpet. Each cup includes a central post that attaches to the carpet. An inverted cup housing is held on the post suspended over the carpet surface. Hanging from the perimeter of the housing are many pivotted elements that extend down to a point where they will be contacted by a ball entering the cup area. They pivot inward with the ball but prevent the ball from rolling out, thereby simulating the ball dropping into a real cup.
