Abstract

A dispensing system comprises a first electronic sensor and a controller. The first electronic sensor may be configured to detect a first change from a first amount of a fluid product in a dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir. The controller may be coupled to the first electronic sensor and configured to receive a first signal from the first electronic sensor indicative of the first change. The dispensing system reservoir may be disposed in the dispensing system. A method for determining a remaining service interval for a dispensing system reservoir is also provided.

Claims (42)

1. A method of determining a remaining service interval of a dispensing system reservoir, comprising:

determining a corrected average usage rate for a dispensing system by monitoring a number of dispersions over a period of time;

detecting a real time amount of fluid product in the dispensing system reservoir by detecting a first change from a first amount of fluid product in the dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir; and

determining the remaining service interval of the dispensing system reservoir based upon the corrected average usage rate and the real time amount of the fluid product in the dispensing system reservoir.

2. The method of claim 1 , comprising:

communicating the remaining service interval via an indicator of the dispensing system.

3. The method of claim 2 , wherein the indicator comprises an audio indicator and the communicating the remaining service interval via an indicator comprises:

communicating the remaining service interval as an audio indication via the audio indicator.

4. The method of claim 2 , wherein the indicator comprises a visual indicator and the communicating the remaining service interval via an indicator comprises:

communicating the remaining service interval as a visual indication via the visual indicator.

5. The method of claim 4 , wherein the communicating the remaining service interval as a visual indication comprises displaying at least one of a mechanical flag, a light, or an electronic read out.

6. The method of claim 1 , comprising:

communicating, via a transceiver of the dispensing system, the remaining service interval to a computer.

7. The method of claim 6 , wherein the communicating the remaining service interval to a computer comprises transmitting an email comprising the remaining service interval via the transceiver.

8. The method of claim 6 , wherein the communicating the remaining service interval to a computer comprises transmitting a text message comprising the remaining service interval via the transceiver.

9. A method of determining a remaining service interval of a dispensing system reservoir, comprising:

determining a first real time amount of fluid product in the dispensing system reservoir at a first time within a first period of time;

determining a second real time amount of fluid product in the dispensing system reservoir at a second time within the first period of time;

determining an average usage rate over the first period of time;

determining a corrected average usage rate of the average usage rate to account for a difference between the first real time amount and the second real time amount;

determining a remaining service interval for the dispensing system reservoir based upon the corrected average usage rate over the first period of time; and

communicating, via a transceiver of a dispensing system, the remaining service interval to a computer.

10. The method of claim 9 , comprising:

determining a third real time amount of the fluid product in the dispensing system reservoir at a third time within the first period of time.

11. The method of claim 10 , wherein the determining the corrected average usage rate comprises determining the corrected average usage rate of the average usage rate to account for a difference between the first real time amount, the second real time amount, and the third real time amount.

12. The method of claim 9 , wherein the communicating the remaining service interval to a computer comprises transmitting a push notification comprising the remaining service interval via the transceiver.

13. A method of determining a remaining service interval of a dispensing system reservoir, comprising:

determining an average usage rate for a dispensing system by monitoring a number of dispersions over a period of time;

detecting a real time amount of fluid product in the dispensing system reservoir by detecting a first change from a first amount of fluid product in the dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir;

determining the remaining service interval of the dispensing system reservoir based upon the average usage rate and the real time amount of the fluid product in the dispensing system reservoir; and

communicating, via a transceiver of the dispensing system, the remaining service interval to a computer.

14. The method of claim 13 , wherein the determining an average usage rate comprises:

determining a corrected average usage rate.

15. The method of claim 13 , comprising:

communicating the remaining service interval via an indicator of the dispensing system.

16. The method of claim 15 , wherein the indicator comprises an audio indicator and the communicating the remaining service interval via an indicator comprises:

communicating the remaining service interval as an audio indication via the audio indicator.

17. The method of claim 15 , wherein the indicator comprises a visual indicator and the communicating the remaining service interval via an indicator comprises:

communicating the remaining service interval as a visual indication via the visual indicator.

18. The method of claim 13 , wherein the communicating the remaining service interval to a computer comprises transmitting an email comprising the remaining service interval via the transceiver.

19. The method of claim 13 , wherein the communicating the remaining service interval to a computer comprises transmitting a text message comprising the remaining service interval via the transceiver.

20. The method of claim 13 , wherein the communicating the remaining service interval to a computer comprises transmitting a push notification comprising the remaining service interval via the transceiver.
