Abstract

A warehousing system includes a container for storing at least one item, a first electronic (e.g., radio frequency identification (RFID)) module associated with the first container, and a controller which wirelessly communicates with first electronic module, for directing a transfer of said at least one item to and/or from said first container. The inventive system may include, for example, a hybrid retail/warehouse system which includes a facility having a shelving area, and a picking area adjacent to the shelving area, and a layout so as to minimize a picking area and a walking distance between a picking area and a shelving area.

Claims

1. A warehousing system comprising:

a first container for storing at least one item,

a first electronic module affixed to said first container, said first electronic module having stored therein a unique identification number that distinguishes the first container from other containers for storing or receiving items in a warehouse;

an antenna integrally formed in the first container and connected to the first electronic module;

a controller which wirelessly communicates with said first electronic module, via the antenna, for activating a signal on the first electronic module for directing a transfer of said at least one item to and from said first container;

a second container for receiving said at least one item from said first container,

a second electronic module affixed to the second container, said second electronic module having stored therein a unique identification number that distinguishes the second container from other containers for storing or receiving items in a warehouse, said second electronic module wirelessly communicating with said controller, for facilitating a transfer of said at least one item from said first container to said second container.

2. The warehousing system according to claim 1, wherein said first electronic module comprises a light emitting device which is activated to indicate that said at least one item should be transferred to and from said first container.

3. The warehousing system according to claim 1, wherein said first electronic module comprises a display device for indicating a content of said first container.

4. The warehousing system according to claim 1, wherein said first container comprises a plastic tote.

5. The warehousing system of claim 1, further comprising:

a facility comprising a shelving area and a picking area adjacent to but physically separate from said shelving area, and having a layout so as to minimize walking distance between the picking area and the shelving area.

6. The warehousing system of claim 5, wherein further comprising a plurality of warehouse antennas, wherein the controller can communicate with the antenna of the first container, or the second container or both at any location within the facility.

7. The warehousing system of claim 6, further comprising a conveyor belt disposed for transporting the first container between the shelving area and the picking area.

8. The warehousing system of claim 5, further comprising a conveyor belt disposed for transporting the first container between the shelving area and the picking area.

9. The warehousing system of claim 5, wherein the first container contains single merchandise item.

10. The warehousing system according to claim 1, wherein said controller wirelessly communicates with said first electronic module via a low frequency signal.

11. The warehousing system according to claim 1, wherein said first electronic module is integrally formed with said first container.

12. The warehousing system according to claim 1, wherein said item comprises a medical device.

13. The warehousing system of claim 1, wherein the first container contains single merchandise item.

14. The warehousing system of claim 1, wherein the first electronic module comprises two visual indicators providing distinguishable visual signals.

15. The warehousing system of claim 14, wherein the first electronic module further comprises a price display, and the controller causes the price display to display the price of the first item.

16. A warehousing method comprising:

storing at least one item in a first container, said first container having a first electronic module affixed to said first container, said first electronic module having stored therein a unique identification number that distinguishes the first container from other containers for storing items in a warehouse;

placing said first container in a shelving area;

providing a communication to the first electronic module indicating that the item in the first container is to be picked for a purchaser;

moving the first container from the shelving area to a picking area in the warehouse in response to the communication to the first electronic module;

providing a communication to a second electronic module associated with a second container located in the picking area indicating that the item in the first container is to be picked for a purchaser by placement in the second container; and

transferring said at least one item from said first container to the second container.

17. The method according to claim 16, wherein said item is accessible to be personally selected by in-store customers and remotely selected by out-of-store customers.

18. The method according to claim 16 wherein said first container comprises a plastic tote.

19. A warehousing system comprising:

a first container for storing at least one item,

a first electronic module affixed to said first container, said first electronic module having stored therein a unique identification number that distinguishes the first container from other containers for storing or receiving items in a warehouse, wherein the first electronic module comprises two visual indicators providing distinguishable visual signals;

a controller which wirelessly communicates with said first electronic module for one of the two visual indicators on the first electronic module for directing a transfer of said at least one item to and from said first container;

a second container for receiving said at least one item from said first container,

a second electronic module affixed to the second container, said second electronic module having stored therein a unique identification number that distinguishes the second container from other containers for storing or receiving items in a warehouse, said second electronic module wirelessly communicating with said controller, for facilitating a transfer of said at least one item from said first container to said second container.

20. The warehousing system of claim 19, wherein the first electronic module further comprises a price display, and the controller causes the price display to display the price of the first item.
