Abstract

Certain dual roll dispensers and methods of dispensing sheet product are provided. In one example, the method includes receiving, by the controller, a first trigger from at least one motion sensor, where the controller is in an awake state before the first trigger is received. The method includes causing, in response to the first trigger, a measurement device to enter an awake state, where the measurement device is configured to measure an amount of product dispensed by the dispenser. The method also includes receiving dispense event information associated with the amount of product dispensed during a dispense event, and storing or transmitting the dispense event information.

Claims

1. A method of managing power consumption at a dispenser comprising a controller, the method comprising:

receiving, by the controller, a first trigger from at least one motion sensor, wherein the controller is in an awake state before the first trigger is received;

causing, in response to the first trigger, a measurement device to enter an awake state, wherein the measurement device is configured to measure an amount of product dispensed by the dispenser;

receiving dispense event information associated with the amount of product dispensed during a dispense event; and

storing or transmitting the dispense event information.

2. The method of claim 1, wherein the dispense event information comprises a length of dispensing time, a product identifier, a dispensing direction of the product, a speed of dispensing, or a combination thereof.

3. The method of claim 2, wherein the length of dispensing time comprises a quiet time interval that occurs after the dispense event is complete.

4. The method of claim 1, further comprising waiting for a predetermined time interval after the first trigger is received by the controller before storing or transmitting the dispense event information.

5. The method of claim 1, wherein the dispenser comprises a first motion sensor and a second motion sensor, and the first trigger is received from either the first motion sensor or the second motion sensor.

6. The method of claim 5, further comprising:

receiving a second trigger from either the first motion sensor or the second motion sensor; and

restarting the predetermined time interval.

7. The method of claim 5, wherein the dispenser comprises a first dispenser portion and a second dispenser portion;

the first motion sensor is positioned at a first side of the dispenser; and

the second motion sensor is positioned at a second side of the dispenser.

8. The method of claim 1, further comprising:

timing out after a maximum operation period, wherein the maximum operation period is measured between consecutive triggers that are received by the controller; and

causing the measurement device to enter a power off or power save mode after timing out.

9. The method of claim 1, further comprising storing or transmitting chronological information associated with the first trigger or the dispense event information.

10. The method of claim 1, wherein the at least one motion sensor is a passive infrared sensor.

11. The method of claim 1, wherein the measurement device is a rotary encoder configured to contact the product.

12. The method of claim 1, wherein the dispense event information is stored, the method further comprising transmitting the stored dispense event information to a remote server.

13. The method of claim 1, wherein the product dispensed by the dispenser comprises tissue paper.

14. The method of claim 13, wherein the dispense event information comprises the length of tissue paper dispensed per usage.

15. The method of claim 1, further comprising:

receiving a second trigger from the at least one motion sensor;

causing the controller to enter the awake state responsive to the second trigger, wherein the second trigger is received before the first trigger, and wherein the measurement device remains in a power save mode before the second trigger is received.

16. A dispenser comprising:

at least one motion sensor;

one or more measurement devices; and

a controller communicatively coupled to the at least one motion sensor and the one or more measurement devices, the controller comprising memory having computer-executable instructions that, when executed by at least one processor, enable the at least one processor to implement a method comprising;

receiving a first trigger from the at least one motion sensor, wherein the controller is in an awake state before the first trigger is received;

causing, in response to the first trigger, one of the one or more measurement devices to enter an awake state, wherein the one of the one or more measurement devices is configured to measure an amount of product dispensed by the dispenser;

receiving, from the one of the one or more measurement devices, dispense event information associated with the amount of product dispensed by the dispenser during a dispense event; and

storing the dispense event information in the memory, or transmitting the dispense event information.

17. The dispenser of claim 16, wherein the dispenser comprises a first motion sensor and a second motion sensor, and the first trigger is received from either the first motion sensor or the second motion sensor.

18. The dispenser of claim 17, wherein the dispenser comprises a first dispenser portion and a second dispenser portion;

the first motion sensor is positioned at a first side of the dispenser; and

the second motion sensor is positioned at a second side of the dispenser.

19. The dispenser of claim 16, wherein the at least one motion sensor is a passive infrared sensor.

20. The dispenser of claim 16, wherein the one or more measurement devices comprises a rotary encoder configured to contact the product.

21. The dispenser of claim 16, wherein the product dispensed by the dispenser comprises tissue paper.
