Title:
ゴール面を通過する物体を検出するためのゴール検出器
Document Type and Number:
Japanese Patent JP2011500112
Kind Code:
A
Abstract:
A system is disclosed for detection of whether a movable object, such as a sports object, e.g. a football or an ice hockey puck, has passed goal plane. It is known to encircle the goal plane with conductors (1, 2, 3, 4) to produce an electromagnetic field to excite signal emitter means in the movable object, alternatively detect the signal emitted by the emitter means. With the present invention these circuits are sectioned into a plurality of separate circuits, which provides an improved spatial resolution of the system in particularly when the movable object is close to the conductors.
