Abstract

The electronic device is used in place of a line judge in tennis or similar sports. The device provides a signal when the game ball makes contact with the line marketing the boundary of the playing surface. A series of magnetic or electrical conductors are provided which are situated around the region and at the line marking the game area boundary. The conductors produce a signal which gives indication of the impact of the game ball. The electrical or magnetic conductors can be in the form of wires, bands or cables laid out singly or in groups.
