Security and tracking system

A security and tracking system comprising

• at least a first signaling unit and a second signaling unit, wherein the second signaling unit is in communicating proximity with the first signaling unit, each respective said signaling unit having a receiver for identifying the location of said respective signaling unit;
• and, a transmitter for transmitting the location of said respective signaling unit when the first and second signaling units are separated by more than a preselected distance;
• and
• a monitoring station capable of receiving information identifying the location of said signaling units.

A method of locating a person, animal or object comprising:

• a) providing an apparatus adapted to be in contact or at least in close proximity to the person, the animal or the object, the apparatus comprising at least a first signaling unit and a second signaling unit, wherein the second signaling unit is in communicating proximity with the first signaling unit, each said respective signaling unit having a receiver for identifying the location of said respective signaling unit;
• and, a transmitter for transmitting the location of said respective signaling unit when the first and second signaling units are separated by more than a preselected distance;
• b) communicating between each said respective signaling unit to determine whether said signaling units are separated by more than the preselected distance;
• and
• c) upon determining that said signaling units are separated by more than the preselected distance, transmitting the location of the signaling units to a monitoring station, optionally activating said signaling unit that may be in a passive mode to transmit its location to the monitoring station.

A method of locating a person, animal or object comprising:

• a) providing an apparatus adapted to be in contact or at least in close proximity to the person, the animal or the object, the apparatus comprising at least a first signaling unit and a second signaling unit, wherein the second signaling unit in proximity with the first signaling unit, each respective said signaling unit having a receiver for identifying the location of said respective signaling unit;
• and, a transmitter for transmitting respective the location of said signaling unit;
• b) transmitting the location of each of the signaling units to a monitoring station;
• c) calculating whether said signaling units are separated by more than a preselected distance;
• and
• d) upon calculating that said signaling units are separated by more than the preselected distance, initiating at least frequent or continuous transmission of location from each of said signaling units, optionally activating said signaling unit that may be in a passive mode to transmit its location to the monitoring station.
