Claim Text:
1. A method for determining where an object or person is located in an Electronic Article Surveillance (“EAS”) detection zone, comprising: simultaneously emitting a first signal from a first emitter and a second signal from a second emitter, where the first and second emitters are positioned so as to point towards the EAS detection zone; concurrently detecting the first and second signals during a first period of time by each of a first detector and a second detector, where the first and second detectors are positioned so as to point towards the EAS detection zone and so as to respectively reside across from the first and second emitters; 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; and using knowledge of where the object or person is within the EAS detection zone to dynamically change an antenna setting for at least one EAS pedestal.
