Abstract

Wireless methods for dispensing water supplied by a main purification unit to a remote dispensing device. The remote dispensing device is fluidly coupled with the main purification unit. A wireless transceiver is associated with the remote dispensing device and another wireless transceiver is associated with the main purification unit. The wireless transceivers communicate across a wireless communications link between the remote dispensing device and the main purification unit. The system may include multiple remote dispensing devices and/or multiple main purification units.

ending the water dispensing event upon receipt of the second wireless signal.

3. The method of claim 2 wherein communicating the second wireless signal further comprises:

relaying the second wireless signal from the main purification unit through at least another remote dispensing device to the remote dispensing device.

4. The method of claim 1 further comprising:

measuring a lapsed time at the main purification unit;

communicating a second wireless signal from the main purification unit to the remote dispensing device containing data instructing the remote dispensing device to end the water dispensing event when the lapsed time is approximately equal to the targeted dispensing time; and

ending the water dispensing event at the remote dispensing device upon receipt of the second wireless signal.

5. The method of claim 4 wherein communicating the second wireless signal further comprises:

relaying the second wireless signal from the main purification unit through at least another remote dispensing device to the remote dispensing device.

6. The method of claim 1 further comprising:

monitoring a purity of the purified water at the main purification unit; and

communicating a second wireless signal encoding an indication of the purity from the main purification unit to the remote dispensing device.

7. The method of claim 6 further comprising:

ending the water dispensing event if the monitored purity is less than a purity set point.

8. The method of claim 1 further comprising:

ending the water dispensing event after the targeted volume or the targeted dispensing time is achieved; and

circulating a flow of the purified water in a closed loop between the remote dispensing device and the main purification unit until another water dispensing event is initiated.

9. The method of claim 1 wherein communicating the first wireless signal further comprises:

relaying the first wireless signal from the remote dispensing device through at least another remote dispensing device to the main purification unit.

10. The method of claim 1 further comprising:

monitoring a purity of the purified water at the remote dispensing device; and

ending the water dispensing event if the monitored purity is less than a purity set point.

11. The method of claim 10 further comprising:

communicating a second wireless signal from the remote dispensing device to the main purification unit containing data indicating that the water dispensing event has ended at the remote dispensing device.

12. The method of claim 11 further comprising:

communicating a second wireless signal from the remote dispensing device to the main purification unit containing data indicating that the water dispensing event has ended at the remote dispensing device.

13. The method of claim 1 further comprising:

measuring an actual volume of water incrementally dispensed with a flow sensor at the remote dispensing device; and

ending the water dispensing event when the actual and targeted volumes are approximately equal.

14. The method of claim 1 wherein the remote dispensing device includes an RFID tag reader, and entering the targeted volume of purified water further comprises:

reading the targeted volume from an RFID tag carried by a container;

dispensing the purified water from the dispenser of the remote dispensing device into the container;

measuring an actual volume of the purified water dispensed into the container; and

ending the water dispensing event when the actual and targeted volumes are approximately equal.

15. The method of claim 14 wherein measuring the actual volume of the purified water dispensed into the container further comprises:

measuring the actual volume with a flow sensor at the remote dispensing device.

16. A method of wirelessly operating a water purification system having a main purification unit and first and second remote dispensing devices each including a dispenser fluidly coupled with the main purification unit, the method comprising:

entering a first targeted volume of purified water or a first targeted dispensing time at one of the first and second remote dispensing devices or at the main purification unit;

initiating a first water dispensing event at the one of the first and second remote dispensing devices to dispense the targeted volume of the purified water from the respective dispenser or to dispense the purified water from the respective dispenser for the targeted dispensing time; and

communicating a first wireless signal containing data indicative of the initiation of the first water dispensing event from the one of the first and second remote dispensing devices to the main purification unit.

17. The method of claim 16 further comprising:
