Abstract

A location tracking system for tracking the location of a person in a premises is disclosed as including a plurality of location sensing devices for assessing the location of the person in the premises; a number of closed circuit television cameras for obtaining visual images of the person; a visual display monitor connected with and receive signals from only one of the closed circuit television cameras at a time; and the visual display monitor is connected with the closed circuit television camera with the higher/highest score of suitability, as calculated in a pre-determined manner. A method of operating a location tracking system for tracking the location of a person in a premises is disclosed as including the steps of (a) providing a number of location sensing devices for assessing the location of the person in the premises; (b) providing a number of closed circuit television cameras for obtaining visual images of the person; (c) providing a visual display monitor for connecting with and receiving signals from only one of the closed circuit television camera at a time; and (d) calculating, in a pre-determined manner, a score of suitability for each of the closed circuit television cameras; and (e) connecting the visual display monitor with the closed circuit television camera with the higher/highest score of suitability.

Claims

1. A location tracking system for tracking the location of at least one moving object, including:

a plurality of location sensing devices adapted to assess the location of said object;

at least two signal receivers adapted to capture signals of and/or relating to said object;

an output device adapted to be connected with and receive signals from only one of said at least two signal receivers at a time for output; and

means adapted to connect said output device with said signal receivers with the higher/highest score of suitability, as calculated in a pre-determined manner.

2. A system according to claim 1 wherein said signal receivers are adapted to capture visual and/or audio signals of and/or relating to said object.

3. A system according to claim 2 wherein said signal receivers comprise at least two closed circuit television cameras.

4. A system according to claim 2 wherein said signal receivers comprise at least two microphones.

5. A system according to claim 1 wherein said score of suitability is calculated in accordance with a pre-defined formula.

6. A system according to claim 1 wherein said output device comprises at least a visual display unit.

7. A system according to claim 1 wherein said output device comprises at least a speaker.

8. A system according to claim 1 further including a plurality of signal output devices adapted to output signals to said object.

9. A system according to claim 8 wherein said signal output devices are adapted to output audio and/or visual signals to said object.

10. A system according to claim 8 further including at least one further signal receiver adapted to be connected with and transmit signals to only one of said plurality of signal output devices at a time.

11. A system according to claim 10 including means adapted to connect said further signal receiver with the audio signal output device with the higher/highest score of suitability, as calculated in a pre-determined manner.

12. A system according to claim 1 wherein said connecting means is adapted to connect the output device with the signal receiver with the higher/highest score of suitability as calculated in said predetermined manner only if the score of suitability of the currently connected signal receiver falls below a pre-determined level.

13. A system according to claim 11 wherein said connecting means is adapted to connect the signal receiver with the signal output device with the higher/highest score of suitability as calculated in said pre-determined manner only if the score of suitability of the currently connected signal output device falls below a pre-determined level.

14. A system according to claim 13 wherein said signal output devices comprise at least two speakers.

15. A system according to claim 13 wherein said signal output devices comprise at least two television sets.

16. A system according to claim 1 further including a data processing apparatus.

17. A method of operating a location tracking system for tracking the location of at least one moving object, including the steps of:

(a) providing a plurality of location sensing devices adapted to assess the location of said object;

(b) providing at least two signal receivers adapted to capture signals of and/or relating to said object;

(c) providing an output device adapted to be connected with and receive signals from only one of said at least two signal receivers at a time for output;

(d) calculating, in a pre-determined manner, a score of suitability for each of said at least two signal receivers; and

(e) connecting said output device with the signal receiver with the higher/highest score of suitability.

18. A method according to claim 17 wherein said signal receivers are adapted to capture visual and/or audio signals of and/or relating to said object.

19. A method according to claim 18 wherein said signal receivers comprise at least two closed circuit television cameras.

20. A method according to claim 18 wherein said signal receivers comprise at least two microphones.

21. A method according to claim 17 wherein said score of suitability is calculated in accordance with a pre-defined formula.

22. A method according to claim 17 wherein said output device comprises at least a visual display unit.

23. A method according to claim 17 wherein said output device comprises at least a speaker.

24. A method according to claim 17 further including a plurality of signal output devices adapted to output signals to said object.

25. A method according to claim 24 wherein said plurality of signal output devices are adapted to output audio and/or visual signals to said object.

26. A method according to claim 24 further including at least one further signal receiver adapted to be connected with and transmit signals to only one of said plurality of signal output devices at a time.

27. A method according to claim 26 including means adapted to connect said further signal receiver with the signal output device with the higher/highest score of suitability, as calculated in a pre-determined manner.

28. A method according to claim 17 wherein said connecting means is adapted to connect the output device with the signal receiver with the higher/highest score of suitability as calculated in said pre-determined manner only if the score of suitability of the currently connected signal receiver falls below a pre-determined level.

29. A method according to claim 27 wherein said connecting means is adapted to connect the signal receiver with the signal output device with the higher/highest score of suitability as calculated in said pre-determined manner only if the score of suitability of the currently connected signal output device falls below a pre-determined level.

30. A method according to claim 29 wherein said signal output devices comprise at least two speakers.

31. A method according to claim 29 wherein said signal output devices comprise at least two television sets.

32. A method according to claim 17 further including a data processing apparatus.
