Ball identification for a table ball game

摘要

Electronic arrangement for detecting and identifying individual balls in a table ball game involves the use of two or more distinct code elements embedded in the balls. When applied to a pool table, the balls landing in the pockets are conveyed by inclined ducts to an electronic detector coupled to a scoring device. The detector recognizes the resonant frequency of each code element and compares the codes detected with the combination of codes assigned to the different balls. The application of the invention to Kelly Pool and Poker Pool is described.
