Product identification system
Methods, systems and apparatus for determining or identifying the type of product in a dispenser based at least in part on the length of rolled product dispensed and/or the radial measurement.
1. A dispenser comprising:
a body including a product holding area configured to hold a rolled product;
a first sensor proximate the product holding area and configured to determine a length of the rolled product dispensed;
a second sensor proximate the product holding area and configured to determine a radial measurement of the rolled product, wherein the second sensor is a single sensor device; and
a processing device configured to communicate with the first and second sensors and to:
(i) determine, multiple times for the rolled product, thicknesses of sheets of the rolled product;
(ii) average the thicknesses; and
(iii) determine a type of the rolled product based on the length of rolled product dispensed and the radial measurement including the average thickness.
2. The dispenser of claim 1 , wherein the determinations of the length of rolled product dispensed and the radial measurement are within a specified time range of one another.
3. The dispenser of claim 1 , wherein the rolled product is bath tissue roll.
4. The dispenser of claim 1 , wherein the rolled product is a paper towel roll.
5. The dispenser of claim 1 , wherein the first sensor is a rotary encoder.
6. The dispenser of claim 1 , wherein the first sensor is an optical sensor.
7. The dispenser of claim 1 , wherein the second sensor is a potentiometer.
8. The dispenser of claim 1 , wherein the type of the rolled product identifies a manufacturer of the rolled product.
9. The dispenser of claim 8 , wherein the type of the rolled product identifies a product level code of the rolled product.
10. The dispenser of claim 1 comprising a motor configured to rotate the rolled product for dispensing, and wherein the processing device is configured to prevent actuation of the motor in response to determining that the type of the rolled product is not an authorized rolled product.
11. The dispenser of claim 1 comprising a transceiver, and wherein the processing device is configured to cause the transceiver to send an alert message in response to determining that the type of the rolled product is not an authorized rolled product.
12. The dispenser of claim 1 , wherein the processing device is configured to determine an amount of rolled product remaining based on one of the radial measurement and the length.
13. The dispenser of claim 12 , wherein the processing device is configured to determine the amount of rolled product remaining based only on data from one of the radial measurement and the length of rolled product dispensed.
14. The dispenser of claim 1 comprising a transceiver, and wherein the processing device is configured to cause the transceiver to send a message identifying the type of the rolled product.
15. The dispenser of claim 1 , comprising a dispenser counter configured to count a number of dispenses.
16. The dispenser of claim 1 comprising a motor configured to rotate the rolled product for dispensing, and wherein the first sensor is configured to count the number of dispenses based on a number of the motor actuations.
