发明名称 Remote controlled deadness board for croquet
摘要 A deadness board apparatus remotely displays the "dead" status of each player in the game of croquet with respect to each other's player or color. The system includes a "dead" scoreboard with colored panels for ball colors and a light in each panel. The "on" or "off" status of the colored panels indicates "dead" or "alive" status of a player with respect to each of the three other colors. The lights are controlled by relays which are in turn controlled remotely by radio signals from transmitters which can be carried by each player. Each transmitter may additionally include a control button for increasing the player's (or team's ) score when his ball is hit through a wicket.
