Zusammenfassung:Systems (100) and methods (1800) for determining where an object or person is located in an EAS detection zone. The methods involve: simultaneously emitting a first signal from a first emitter and a second signal from a second emitter; concurrently detecting the first and second signals during a first period of time by each of a first detector and a second detector; and determining where the object or person is within the EAS detection zone based on a pattern of a signal output from at least one of the first and second detectors which reflects that at least one of the first and second signals is blocked by the object or person during at least one of a second period of time and a third period of time in which the object or person is traveling through the EAS detection zone.
