The invention refers to a method of using a tag in a localisation system, the method comprising at said tag operating a magnetic induction signal detection circuit to detect signals, and upon detection of a magnetic induction signal comprising a first identification code: correlating the magnetic induction signal comprising said first identification code to an ultrasound signal comprising a second identification code, received via an ultrasound signal detection circuit. If said correlation reveals an association between said first identification code and said second identification code: a radio frequency announcement signal is transmitted via a radio frequency signal transmitter circuit to signify said association. The invention also refers to a method of using a beacon in said localisation system, as well as the localisation system comprising one or more tags and one or more beacons.

False alarm avoidance system

The invention pertains to a method for detecting a tag () in an area monitored by one or more beacons (), the tag () comprising a magnetic induction module () and a transmitter (), the method comprising the following steps at said tag: receiving, by means of said magnetic induction module, a first beacon message as variations in a magnetic field, said first beacon message comprising beacon information; extracting said beacon information from said first beacon message; and conditionally on said beacon information, transmitting a localisation message by means of said transmitter ().

Localisation system

The invention pertains to a method and system for determining a location of an identification tag () in a monitored area. The method comprises using a plurality of beacons () to broadcast () beacon messages comprising an identification element relating to the originating beacon; receiving () at a first set of beacons a localization message from an identification tag (), the tag having received () a beacon message, extracted () the identification element from the received beacon message, and transmitted () information related to the identification element as part of the localization message; performing () a first level of localization of the tag on the basis of characteristics of the respective copies of the localization message received at the first set of beacons; and performing () a second level of localization of the tag on the basis of the information related to the identification element.
