Abstract

A system for developing firefighting skills including a display device configured to display a simulated fire, wherein the display device has a front surface. The system further includes a sensor configured to detect an actual or simulated extinguishant that is directed at the front surface, wherein the sensor is directly coupled to the front surface of the display device.

Claims

1. A system for developing firefighting skills including:

a display device configured to display a simulated fire, wherein the display device has a front surface; and

a sensor configured to detect an actual or simulated extinguishant that is directed at said front surface, wherein the sensor is directly coupled to said front surface of said display device, and wherein the system is configured to withstand a liquid stream at a pressure of at least about 50 psi directed at said front surface while continuing to operate and display said simulated fire.

2. The system of claim 1 wherein display device includes a protective screen which defines said front surface, and wherein said sensor is directly coupled to, positioned on or embedded in said protective screen.

3. The system of claim 2 wherein said protective screen is transparent or clear, and said sensor is in direct contact with said protective screen.

4. The system of claim 1 wherein display device includes a protective screen which defines said front surface, and wherein said sensor is positioned in front of said protective screen, or positioned behind said protective screen, or embedded in said protective screen.

5. The system of claim 1 wherein said sensor is spaced away from an outer edge of said screen in front view such that said sensor is configured to be integrated into said fire displayed by said display device such that when said fire is displayed said displayed fire surrounds said sensor on all sides thereof in front view.

6. The system of claim 1 wherein said display device is displaying a simulated fire which surrounds said sensor on all sides thereof in front view.

7. The system of claim 1 wherein the system includes a plurality of sensors configured to detect an extinguishant that is directed at said front surface, wherein each sensor is directly coupled to said front surface of said display device.

8. The system of claim 1 further comprising a controller operatively coupled to said display device and to said sensor, wherein said controller is configured to receive outputs from said sensor and responsively control said simulated fire on said display device.

9. The system of claim 8 wherein said controller is configured to monitor an output of said sensor such that proper use of said extinguishant, as determined by said controller, causes said controller to reduce a size of said fire displayed by said display device.

10. The system of claim 8 wherein said controller is configured to determine a location and a magnitude of said extinguishant.

11. The system of claim 10 wherein said location of said extinguishant includes at least one of an envelope of impact of said extinguishant or a centroid of said extinguishant on said front surface of said display device, and wherein said magnitude of said extinguishant includes an actual volume of said extinguishant, in a case of a tangible extinguishant, or a projected volume of said extinguishant, in a case of a non-tangible extinguishant.

12. The system of claim 1 wherein said sensor is configured to detect at least one of a liquid or a solid or a foam extinguishant.

13. The system of claim 1 wherein said sensor is configured to detect an electromagnetic extinguishant.

14. The system of claim 1 wherein said sensor is configured to measure a change in temperature.

15. A method for developing firefighting skills including:

displaying a simulated fire via display device having a front surface, wherein said display device is water-tight and configured to withstand a liquid stream at a pressure of at least about 50 psi directed at said front surface while continuing to display said simulated fire; and

sensing via a sensor an actual or simulated extinguishant that is directed at said front surface, wherein the sensor is directly coupled to said front surface of said display device.

16. A system for developing firefighting skills including:

a display device configured to display a simulated fire; and

a sensor system including at least one sensor configured to detect an actual extinguishant and at least one sensor configured to detect a simulated extinguishant that is directed at said simulated fire, wherein said display device is water-tight and configured to withstand a liquid stream at a pressure of at least about 50 psi directed at said display device while continuing to operate and display said simulated fire.

17. The system of claim 16 wherein said sensor system is configured to determine a location and a magnitude of said extinguishant impinging upon said display device.

18. The system of claim 17 wherein said sensor system is configured to responsively control said simulated fire on said display device based upon said sensed location and magnitude of said extinguishant.

19. The system of claim 18 wherein said sensor system is configured to monitor said sensed location and magnitude of said extinguishant over time such that proper use of said extinguishant, as determined by said monitored location and volume over time, causes said sensor system to reduce a size of said fire displayed by said display device.

20. The system of claim 17 wherein said location of said extinguishant includes at least one of an envelope of impact or a centroid of said extinguishant on said display device.

21. The system of claim 17 wherein said magnitude comprises an actual volume in a case of a tangible extinguishant, or a projected volume of said extinguishant in a case of a non-tangible extinguishant, or an envelope of impact of said extinguishant.

22. The system of claim 17 wherein said sensor system includes a controller configured to determine said location and volume of said extinguishant and responsively control said simulated fire on said display device.

23. The system of claim 17 wherein said sensor system includes a plurality of thermistors, each thermistor being operatively coupled to a proportional-integral-derivative controller to determine said location and said magnitude.

24. The system of claim 16 wherein said display device has a front surface, and wherein at least one of said sensors is directly coupled to said front surface of said display device.

25. The system of claim 16 wherein said sensor system is configured to detect at least one of a liquid or a solid or a foam extinguishant.

26. The system of claim 16 wherein said sensor system is configured to detect an electromagnetic extinguishant.

27. The system of claim 16 wherein said sensor system is configured to measure a change in temperature.

28. A method for developing firefighting skills including:

displaying a simulated fire via a display device; and

sensing via a sensor system an actual extinguishant and a simulated extinguishant that is directed at said simulated fire, wherein said display device is water-tight and configured to withstand a liquid stream at a pressure of at least about 50 psi directed at said display device while continuing to operate and display said simulated fire.

29. The method of claim 28 wherein said sensor system is configured to determine a location and magnitude of said extinguishant impinging upon said display device.
