Abstract:

A monitoring and alerting system for luggage including a master unit and a plurality of slave units. Each slave unit has a unique identity. The master unit and slave units each have a status display having numbered indicia which normally displays the numbered indicia for the slave units in a first color, and has an annunciator. When the master unit and slave units are separated by a predetermined distance, an alert condition is established whereby the numbered indicia for that slave unit changes to a second color and both the master unit and slave unit sound an alert with their annunciators. A wire loop may be used to attach the slave units to luggage, which normally maintains a closed circuit, such that if the wire loop is removed from the luggage and becomes open circuited while the slave unit is on, the alert condition is established.
