Abstract

Requesting the location of items in a storage area may include accessing an entry in a list of items to be selected from item storage subareas. The entry may be associated with an item identifier code corresponding to an item storage subarea. A short-range activation signal corresponding to the item identifier code may be transmitted. The short-range activation signal may cause an indicator device associated with the item identifier code and in physical proximity to the short-range activation signal to transmit an indicator signal that indicates the location of the corresponding item storage subarea.

Claims

1. An apparatus for requesting the location of items in a storage area, the apparatus comprising:

a mobile computing device for accessing an entry in a list of items to be selected from item storage subareas within an item storage area, the entry being associated with an item identifier code corresponding to an item storage subarea;

a detecting device for detecting selection by a user of at least one item corresponding to the entry; and

a transmitter communicatively coupled to the mobile computing device for;

transmitting a short-range activation signal corresponding to the item identifier code, the short-range activation signal causing an indicator device associated with the item identifier code and in physical proximity to the short-range activation signal to transmit an indicator signal in response to the short-range activation signal that indicates the location of the corresponding item storage subarea; and

terminating transmission of the short-range activation signal in response to the detecting device detecting selection by the user of the at least one item corresponding to the entry.

2. The apparatus of claim 1 wherein the activation signal comprises an infrared signal.

3. The apparatus of claim 2 wherein the activation signal includes an embedded identifier code associated with the entry.

4. The apparatus of claim 1 wherein the transmitter comprises a mobile transmitter.

5. The apparatus of claim 1 wherein the mobile computing device comprises a personal digital assistant, a laptop computer, or a belt-mounted computer.

6. The apparatus of claim 1 wherein the mobile computing device receives the entry in the list of items from an enterprise system.

7. The apparatus of claim 6 wherein the enterprise system comprises an inventory management system.

8. The apparatus of claim 6 wherein the mobile computing device receives the entry from the enterprise system by using a docking station.

9. The apparatus of claim 6 wherein the mobile computing device receives the entry from the enterprise system over a wireless network.

10. The apparatus of claim 9 wherein the wireless network comprises a wireless local area network.

11. The apparatus of claim 9 wherein the wireless network comprises a wide area radio network.

12. The apparatus of claim 9 wherein the wireless network comprises a cellular modem network.

13. The apparatus of claim 1 wherein the mobile computing device includes a stationary component and a mobile component.

14. The apparatus of claim 1 wherein the activation signal comprises a short-range radio signal.

15. The apparatus of claim 1 wherein the activation signal comprises a visible light signal.

16. The apparatus of claim 1 wherein the transmitter comprises a portable device that may be attached to the clothing of a person.

17. The apparatus of claim 16 wherein the portable device comprises a badge.

18. The apparatus of claim 1 wherein the transmitter is stationary and located at fixed points in the item storage area.

19. The apparatus of claim 1 wherein the mobile computing device and the transmitter are integrated in a single unit.

20. The apparatus of claim 19 wherein the single unit comprises a palmtop computing device with an integrated infrared communications feature.

21. The apparatus of claim 1 wherein the mobile transmitter is operable to continuously transmit the activation signal.

22. The apparatus of claim 1 wherein the mobile transmitter is operable to transmit the activation signal periodically.

23. The apparatus of claim 22 wherein the duration of the period between transmissions of the activation signal is fixed.

24. The apparatus of claim 22 wherein the duration of the period between transmissions of the activation signal is random.

25. The apparatus of claim 1 wherein the short-range activation signal corresponds to a single type of item.

26. The apparatus of claim 1 wherein each entry in the list of items to be selected includes a single type of item to be selected and a quantity of the items of the single type to be selected.

27. The apparatus of claim 1 wherein the item identifier code is unique to a single type of item.

28. The apparatus of claim 1 wherein the detecting device is for detecting selection by the user of the at least one item from the item storage subarea corresponding to the item identifier code.

29. The apparatus of claim 28 wherein selection by the user of the at least one item comprises manual selection by the user of the at least one item.

30. The apparatus of claim 1 wherein the detection device detects selection based on the user interacting with a user interface of the apparatus to indicate that selection is complete.

31. The apparatus of claim 30 wherein the detection device detects selection based on the user manually interacting with the user interface of the apparatus to indicate that selection is complete.

32. The apparatus of claim 31 wherein the user manually interacting with the user interface comprises the user interacting through use of at least one of a stylus, a keyboard, and a headset.

33. The apparatus of claim 1 wherein the detection device detects selection based on communications originating from proximity detection circuitry.

34. The apparatus of claim 1 wherein the transmitter is physically coupled to the mobile computing device.

35. The apparatus of claim 1 wherein the transmitter is communicatively coupled to the mobile computing device over a wireless connection.

36. The apparatus of claim 35 wherein the transmitter is stationary and located at fixed points in the item storage area.

37. A method for requesting the location of items in a storage area, the method comprising:

accessing an entry in a list of items to be selected from item storage subareas within an item storage area, the entry being associated with an item identifier code corresponding to an item storage subarea;

detecting selection by a user of at least one item corresponding to the entry;

transmitting a short-range activation signal corresponding to the item identifier code, the short-range activation signal causing an indicator device associated with the item identifier code to transmit an indicator signal in response to the short-range activation signal that indicates the location of the corresponding item storage subarea;

terminating transmission of the short-range activation signal in response to detecting selection by a user of the at least one item corresponding to the entry.

38. The method of claim 37 wherein the activation signal comprises an infrared signal.

39. The method of claim 38 wherein the activation signal includes an embedded identifier code associated with the entry.

40. The method of claim 37 wherein accessing the entry includes accessing the entry using a mobile computing device.
