【発明の名称】タグ付きゴルフボール及び検出システム
Document Type and Number:
Japanese Patent JP2000503877
Kind Code:
A
Abstract:
Golf balls have a passive tag at selected capacitance inserted within their interior, to enable detection of the presence of the tag, and of the ball, using an electronic detecting system. The tags are passive, being energized into emitting a signal by the presence of a detector field of predetermined characteristics such that the tag generates a responsive signal, which can be detected by an adjacent detector circuit, to signal the presence of a tagged ball. One field of use is for driving ranges, where the unauthorized removal of range balls constitutes an unacceptable loss for the proprietors of the establishment. The system also lends itself to finding lost balls, using a hand-portable detector, and to use with other types of game ball.
