Ball identification for a table ball game
First Claim
1. A table ball game having a playing surface and ball traps, electronic detection means associated with one or more of the ball traps, a plurality of balls having identification means associated therewith, said identification means comprising at least one resonant circuit in each said ball, said at least one circuit in each said ball being tuned to resonate at a different frequency than at least one said circuit in each of the other said balls, said at least one circuit of each said ball being capable of being individually detected by said electronic detection means, said electronic detection means being coupled to scoring means to record the entry of balls into said ball traps, the electronic detection means comprising plural coils or a single coil with taps in a complex pattern, either of these coil means arranged to generate a complex field having a plurality of orthogonal axes, and means for detecting perturbations in said field.

Abstract
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.
