Abstract

Energy harvesting devices provide power to devices of emergency equipment stations (e.g., fire extinguisher station, fire alarm pull station, defibrillator station, etc.) distributed throughout a facility to monitor one or more internal or external conditions (e.g., identifiable objects detected near the station, presence of an obstruction restricting access to the station, etc.) and relay information about the monitored conditions to a central station.

Claims

1. A system comprising:

at least one energy harvesting device for harvesting energy from inside a building;

at least one emergency equipment station that includes an emergency assistance device and a plurality of modules powered, at least in part, by the at least one energy harvesting device, wherein the at least one energy harvesting device is a small autonomous device associated with the at least one emergency equipment station;

communications circuitry for the at least one emergency equipment station; and

a processor in the at least one emergency equipment station, wherein the processor is configured to receive and process data from the at least one energy harvesting device and the plurality of modules, wherein the processor allocates power harvested by the energy harvesting device to the plurality of modules, and wherein the processor transmits power distribution data through the communications circuitry to a central station located remotely from the emergency equipment station.

2. The system of claim 1 wherein the processor is configured to transmit information representative of an operational state of the plurality of modules to the central station.

3. The system of claim 1 wherein the emergency assistance device includes a fire extinguisher.

4. The system of claim 1 wherein the emergency assistance device includes a fire pull alarm.

5. The system of claim 1 wherein the emergency assistance device includes an emergency lighting device.

6. The system of claim 1 wherein the emergency assistance device includes a defibrillator.

7. The system of claim 1 wherein the at least one energy harvesting device is configured to harvest energy from a manmade power source.

8. The system of claim 1 wherein the processor is configured to convert power.

9. The system of claim 1 wherein the at least one energy harvesting device includes a piezoelectric crystal for harvesting electrical energy from mechanical strains.

10. The system of claim 1 wherein the at least one energy harvesting device includes one or more antennas to collect energy from radio waves.

11. The system of claim 1 wherein the at least one energy harvesting device includes a solar panel for harvesting electrical energy from ambient light energy.

12. An apparatus for remote inspection comprising:

a gauge powered by an energy harvesting device and configured to be in communication with a volume defined by a portable tank for detection and display of a pressure condition of content contained within the volume, wherein the energy harvesting device is a small autonomous device associated with the gauge and configured to harvest energy from inside a building;

a processor configured to receive and process data from the energy harvesting device and one or more modules of the gauge, wherein the processor allocates power harvested by the energy harvesting device to the one or more modules of the gauge, and wherein the processor transmits power distribution data through communications circuitry to a central station located remotely from the apparatus; and

an electronic circuit disposed in communication with the gauge and adapted to signal to the remote central station upon detection of a predetermined internal condition including an out-of-range pressure condition of the portable tank detected by a detector of the gauge.

13. The apparatus of claim 12 further comprising a sensor to detect a predetermined external condition of the portable tank.

14. The apparatus of claim 13 wherein the sensor detects a removal of the portable tank from an installed position.

15. The apparatus of claim 13 wherein the sensor detects an obstruction to viewing of the portable tank.

16. The apparatus of claim 13 wherein the sensor detects an obstruction to access of the portable tank.

17. The apparatus of claim 13 wherein the portable tank includes a fire extinguisher.

18. The apparatus of claim 13 wherein the gauge is further powered by an auxiliary power supply.

19. The apparatus of claim 13 wherein the energy harvesting device includes a piezoelectric crystal for harvesting electrical energy from mechanical strains.

20. The apparatus of claim 13 wherein the energy harvesting device includes a solar panel for harvesting electrical energy from ambient light energy.
