Abstract

A component monitoring system is configured to indirectly monitor an operative health status of an operative component. The component monitoring system includes an ambient condition sensor within a chamber, an operative component coupled to the chamber. The ambient condition sensor is configured to sample an ambient condition within the chamber when the operative component is active. The ambient condition sensor is configured to output ambient condition data indicative of the ambient condition detected by the ambient condition sensor. At least one control unit is in communication with the ambient condition sensor. The control unit(s) is configured to indirectly determine the operative health status of the operative component through an analysis of the ambient condition data.

First claim

What is claimed is:

1. A component monitoring system that is configured to indirectly monitor an operative health status of an operative component, the component monitoring system comprising:
an ambient condition sensor within a chamber;
an operative component coupled to the chamber, wherein the ambient condition sensor is configured to sample an ambient condition within the chamber when the operative component is active, wherein the ambient condition sensor is configured to output ambient condition data indicative of the ambient condition sampled by the ambient condition sensor;
at least one control unit that is in communication with the ambient condition sensor, wherein the at least one control unit is configured to indirectly determine the operative health status of the operative component through an analysis of the ambient condition data; and
one or more environmental sensors in communication with the at least one control unit, wherein the at least one control unit is configured to correlate one or more environmental parameters detected by the one or more environmental sensors with the ambient condition data.

2. The component monitoring system of claim 1 , wherein the ambient condition sensor is not coupled to the operative component.

3. The component monitoring system of claim 1 , wherein the ambient condition sensor is an ambient air pressure sensor, wherein the chamber is a lavatory onboard a vehicle, and wherein the operative component is a vacuum generator of a vacuum sub-system coupled to a toilet within the lavatory.

4. The component monitoring system of claim 1 , wherein the ambient condition sensor is an ambient temperature sensor.

5. The component monitoring system of claim 1 , wherein the at least one control unit is configured to store historical data regarding a plurality of operative health status stages of the operative component, and wherein the at least one control unit is configured to compare the ambient condition data with the plurality of operative health status stages of the operative component to determine the operative health status of the operative component.

6. The component monitoring system of claim 5 , wherein the plurality of operative health status stages include proper functioning, diminished capacity, and impending inoperability.

7. The component monitoring system of claim 1 , wherein the ambient condition sensor is in a dormant state at least for a portion of time when the operative component is inactive.

8. The component monitoring system of claim 1 , wherein the one or more environmental parameters comprise one or more of an altitude, latitudinal position, longitudinal position, a velocity of a vehicle, or an acceleration of the vehicle.

9. The component monitoring system of claim 1 , wherein the at least one control unit is onboard a vehicle.

10. The component monitoring system of claim 1 , wherein the at least one control unit is within a monitoring center that is remotely located from the chamber.

11. The component monitoring system of claim 1 , wherein the at least one control unit is configured to predict a time of replacement of the operative component based on the analysis of the ambient condition data.

12. A component monitoring method for indirectly monitoring an operative health status of an operative component, the component monitoring method comprising:
disposing an ambient condition sensor within a chamber;
coupling an operative component to the chamber;
using the ambient condition sensor to sample an ambient condition within the chamber when the operative component is active;

communicatively coupling at least one control unit to the ambient condition sensor;
analyzing the ambient condition data with the at least one control unit;
correlating one or more environmental parameters sampled by one or more environmental sensors with the ambient condition data; and
indirectly determining the operative health status of the operative component through the analyzing.

13. The component monitoring method of claim 12 , wherein the ambient condition sensor is an ambient air pressure sensor, wherein the chamber is a lavatory onboard a vehicle, and wherein the operative component is a vacuum generator of a vacuum sub-system coupled to a toilet within the lavatory.

14. The component monitoring method of claim 12 , further comprising:
storing historical data regarding a plurality of operative health status stages of the operative component in at least one data storage unit, and wherein the analyzing comprises comparing the ambient condition data with the plurality of operative health status stages of the operative component.

15. The component monitoring method of claim 14 , wherein the plurality of operative health status stages include proper functioning, diminished capacity, and impending inoperability.

16. The component monitoring method of claim 12 , further comprising operating the ambient condition sensor in a dormant state at least for a portion of time when the operative component is inactive.

17. The component monitoring method of claim 12 , further comprising using the at least one control unit to predict a time of replacement of the operative component based on the analyzing.

18. A vehicle comprising:
a lavatory including a toilet coupled to a vacuum sub-system having at least one operative component coupled to the lavatory;
an ambient condition sensor within the chamber, wherein the ambient condition sensor is configured to sample an ambient air pressure within the lavatory when the toilet is flushed, wherein the ambient condition sensor is configured to output ambient pressure data indicative of the ambient fir pressure detected by the ambient condition sensor, wherein the ambient condition sensor is in a dormant state at least for a portion of time when the operative component is inactive, wherein the ambient condition sensor is not coupled to the operative component;
