1. A method of determining offside in soccer using a combination of sensors on the players and detectors on the field, all analyzed using a central server:

  • (1) assign distinct wireless sensors for players, with the two teams being clearly distinguishable;

    (2) a third distinct class of sensor on the ball to allow it to clearly distinguished from the others;

    (3) A network of fixed detectors along the field which read inputs from the sensors;

    these detectors can be on the field as well as on the goal posts.(4) determine the location of each player and the ball using “

    triangulation”

    or other location detection methods,(5) determine if the ball and the offense player is on the opposite side of the field,if the ball is not near the offense player, ensure that there are at least two defense players between the offense player and the opposite goal,(6) determine if the offense player was not offside when the ball was passed to him,if the offside criterion are met, enable a signal to indicate the infraction
