Abstract

A system for automatically monitoring merchandise in a retail sales environment is provided. The system includes a display fixture configured to store and display for sale a group of perishable items and one or more gas emission sensors associated with the display fixture and configured to measure gas emissions from the group of perishable items. The system further includes a control circuit coupled to the one or more gas emission sensors and configured to receive a gas emission measurement taken at the display fixture, compare the gas emission measurement with stored gas emission data associated with a category of the group of perishable items; and make a determination corresponding to the group of perishable items based on the comparison.

Claims

1. A system for automatically monitoring gas emissions of perishable goods in a retail sales environment comprising:

a display fixture configured to store and display for sale a group of perishable items;

one or more gas emission sensors integrated into a structure of the display fixture and configured to measure gas emissions from the group of perishable items on the display fixture;

a control circuit coupled to the one or more gas emission sensors and configured to;

receive a gas emission measurement taken at the display fixture;

add the gas emission measurement to a history of gas emission measurements associated with the group of perishable items;

compare the history of gas emission measurements of the group of perishable items with stored gas emission data associated with a category of the group of perishable items, wherein the stored gas emission data comprises a gas emission over time profile associated with the category;

make a determination corresponding to the group of perishable items based on the comparison; and

determine whether to apply a discount to the group of perishable items based on the determination and one or more of a forecasted rate of sales, an expected time between purchase and use by a customer, and incoming inventory information.

2. The system of claim 1, wherein the group of perishable items comprises one or more of produce, dairy, meat, seafood, plant, floral, deli, prepared meals and bakery goods.

3. The system of claim 1, wherein the category of the group of perishable items corresponds to one or more of a genus, a species, a variety, a cultivar, a growth location, and a growth time.

4. The system of claim 1, wherein the control circuit is further configured to:

identify the group of perishable items based on the gas emission measurement and determine the category for the group of perishable items.

5. The system of claim 1, wherein the determination comprises a determination of one or more of:

freshness, estimated expiration date, item presence, item location, and item type.

6. The system of claim 1, wherein the control circuit is further configured to:

collect gas emission measurements from a plurality of groups of perishable items and compare the collected gas emission measurements with a planogram of a retail space to determine whether the planogram is followed.

7. A method for automatically monitoring gas emissions of perishable goods in a retail sales environment comprising:

taking, at a display fixture, a gas emission measurement with one or more gas emission sensors integrated into a structure of the display fixture, the display fixture being configured to store and display for sale a group of perishable items on the display fixture;

providing the gas emission measurement to a control circuit;

adding the gas emission measurement to a history of gas emission measurements associated with the group of perishable items;

comparing, by the control circuit, the history of gas emission measurements of the group of perishable items with stored gas emission data associated with a category of the group of perishable items, wherein the stored gas emission data comprises a gas emission over time profile associated with the category;

making, by the control circuit, a determination corresponding to the group of perishable items based on the comparing; and

determining whether to apply a discount to the group of perishable items based on the determination and one or more of a forecasted rate of sales, an expected time between purchase and use by a customer, and incoming inventory information.

8. The method of claim 7, wherein the group of perishable items comprises one or more of produce, dairy, meat, seafood, plant, floral, deli, prepared meals and bakery goods.

9. The method of claim 7, wherein the category of the group of perishable items corresponds to one or more of a genus, a species, a variety, a cultivar, a growth location, and a growth time.

10. The method of claim 7, further comprising:

identifying the group of perishable items based on the gas emission measurement and determining the category for the group of perishable items.

11. The method of claim 7, wherein the making the determination step comprises making a determination of one or more of:

freshness, estimated expiration date, item presence, item location, and item type.

12. The method of claim 7, further comprising:

collecting gas emission measurements from a plurality of groups of perishable items and comparing the collected gas emission measurements with a planogram of a retail space to determine whether the planogram is followed.

13. An apparatus for automatically monitoring gas emissions of perishable goods in a retail sales environment comprising:

a control circuit; and

a non-transitory computer readable memory storing a set of instructions executable by the control circuit and configured to cause the control circuit to perform the steps of;

receive a gas emission measurement measured with one or more gas emission sensors integrated into a structure of a display fixture configured to store and display for sale a group of perishable items on the display fixture;

add the gas emission measurement to a history of the gas emission measurements associated with the group of perishable items;

compare the history of gas emission measurements of the group of perishable items with stored gas emission data associated with a category of the group of perishable items;

make a determination corresponding to the group of perishable items based on the comparison; and

determine whether to apply a discount to the group of perishable items based on the determination and one or more of a forecasted rate of sales, an expected time between purchase and use by a customer, and incoming inventory information.

14. A method of automatically monitoring gas emissions of perishable goods in a retail sales environment comprising:

by a control circuit,

receiving a gas emission measurement measured with one or more gas emission sensors integrated into a structure of a display fixture configured to store and display for sale a group of perishable items on the display fixture;

adding the gas emission measurement to a history of the gas emission measurements associated with the group of perishable items;

comparing the history of gas emission measurements of the group of perishable items with stored gas emission data associated with a category of the group of perishable items, wherein the stored gas emission data comprises a gas emission over time profile associated with the category;

making a determination corresponding to the group of perishable items based on the comparing; and

determining whether to apply a discount to the group of perishable items based on the determination and one or more of a forecasted rate of sales, an expected time between purchase and use by a customer, and incoming inventory information.
