System and method for article and proximity location
First Claim
1. A luggage locating system comprising:
- a luggage location unit having a transmitter for transmitting an identifying code and having a housing which is durable;
a sensor to sense cargo compartment environment; and
an indicator unit having a receiver for receiving said identifying code and for indicating receipt of said identifying code to indicate that said luggage location unit 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.

Abstract
A system and method which enable an airline passenger who is traveling with articles, such as baggage and the like, to easily locate them upon arrival to the airport luggage retrieval point, even among a mass of look-alike baggage articles around it. According to an embodiment of the invention a luggage location unit is described, having a transmitter for transmitting an identifying code, a sensor to sense cargo compartment environment and an indicator unit having a receiver for receiving the identifying code and for indicating that the luggage article is in proximity with the indicator unit. The system may be activated automatically by a light sensor. The system and method according to the invention may be used for other uses such as for locating a vehicle in a parking lot or for keeping a child in a close distance form an adult.
