Abstract

The present invention relates to a method of monitoring the movements of an individual in and around buildings, rooms and other spaces, wherein each individual carries a passive transponder which has an individual-unique identity and which is intended for co-action with an active antenna that is connected, either directly or indirectly, to a monitoring centre (13) for transmitting signals received from transponders, and wherein a plurality of antennas (12) are placed in and around the buildings, rooms or other spaces to be monitored. The signals transmitted to the exercise centre (13) are used to show movements of the individual in the form of a three-dimensional animated picture on a picture screen.

Claims

1. A method of monitoring movements of an individual in and around buildings, rooms and other spaces, wherein each individual carries a passive transponder that has an individual-unique identity and that is intended for co-action with an active antenna which is connected, either directly or indirectly, to a monitoring centre (13) for transmitting signals received from transponders, and wherein a plurality of antennas (16, 17, 18, 19, 20) are positioned in and around the buildings, rooms or other spaces to be monitored, characterised by using the signals sent to the monitoring centre (13) to show movements of individuals in the form of a three-dimensional animated picture on a picture screen.

2. A method according to claim 1, characterised by placing on different parts of the body of said individual transponders that have defined identities, so that the manner in which the individual moves can be shown in the animated picture.

3. A method according to claim 2, characterised by placing transponders on the feet, knee, stomach and hands of respective individuals.

4. A method according to any one of the preceding claims, characterised by placing antenna loops around window openings (16) and door openings (17) in said buildings.

5. A method according to any one of the preceding claims, characterised by placing antenna loops generally evenly over the entire floor surface (18) in respective buildings.

6. A method according to any one of the preceding claims, characterised by providing objects (21) in and around the building with transponders.

7. A method according to any one of the preceding claims, characterised by providing exercise material, such as weaponry, hand grenades, explosive material and the like with transponders.

8. A method according to any one of the preceding claims, characterised by providing the buildings with hit acknowledging detectors which function to register simulated hits on the building and which are coupled to the antenna loops.
