System and method for article and proximity location

A luggage locating system comprising:

• at least two luggage location units, each comprising:
• a transmitter for transmitting an identifying code uniquely identifying said luggage location unit and having a housing which is durable;
• and
• a sensor to sense cargo compartment environment;
• and
• an indicator unit having a receiver for receiving said identifying codes and for indicating receipt of said identifying codes to indicate that at least one of said luggage location units is in proximity with said indicator unit,
• wherein said sensor is at least one sensor from a list of comprising a light intensity level sensor and a temperature variation sensor;
• and
• wherein said transmitter is adapted to adjust one or more parameters from a list of parameters comprising:
• time of transmission, time interval between transmissions identifying code and frequency of transmission, according to the region where it is situated, by detecting the transmission frequencies used in said region.

A method for location a luggage article comprising:

• attaching a location unit to a luggage article,
• transmitting an identifying code by transmitter located within said location unit, upon sensing of a change in the environment indicative of emerging from a cargo compartment of an aircraft to an airport environment;
• and
• providing an indication at indicator unit upon receipt of said identifying code transmitted by said transmitter;
• and
• adjusting one or more parameters from a list of parameters comprising:
• time of transmission, time interval between transmissions, identifying code and frequency of transmission, according to the region where it is situated, by detecting the transmission frequencies used in said region.
