Abstract

A deliver and pickup determination system (DDS)(10) for determining whether an object (18) has been delivered at or picked up from a collection-unit (14) such as a mailbox, postbox drop-box, cubby-hole, etc. A radio-frequency identification (RFID) tag (24) is placed in fixed conjunction with each collection-unit of interest, wherein there typically can be tens or hundreds comprising one or more collection-stations (12). A detection and recording device (DRD)(26) worn about the hand of the clerk then senses and collects information about each RFID tag when brought into proximity with it as the object is handled at the collection-unit.

Claims

1. A system for determining whether a clerk has delivered or picked up an object at a particular collection-unit in a collection-station including a plurality of permanently stationary collection-units, wherein the particular collection-unit is assigned to an owner of the object, comprising:

a radio-frequency identification (RFID) tag placed in fixed conjunction with the particular collection-unit; and

a detection and recording device (DRD) worn about the hand of the clerk to sense and collect information about said RFID tag when brought into proximity with it as the object is handled at the particular collection-unit.

2. The system of claim 1, wherein said RFID tag includes a passive type RFID device.

3. The system of claim 1, wherein said RFID tag is placed in fixed conjunction with the particular collection-unit by semi-permanent affixation.

4. The system of claim 3, wherein said RFID tag is embodied in a sticker.

5. The system of claim 1, wherein said RFID tag is placed in fixed conjunction with the particular collection-unit by temporarily locating said RFID tag stationary in the particular collection-unit for said DRD to sense.

6. The system of claim 1, wherein said DRD collects said information about said RFID tag automatically as said DRD is brought close enough to sense said RFID tag.

7. The system of claim 1, wherein said DRD is triggered to collect said information about said RFID tag by a stimulus other than just being close enough to sense said RFID tag.

8. The system of claim 7, wherein said DRD is triggered by at least one member of the set consisting of a physical action by the clerk, a change in a magnetic field, a change in ambient light, and a position calculation based on a radio signal.

9. The system of claim 1, wherein said DRD includes a clock to time-stamp said information.

10. The system of claim 1, wherein said DRD immediately communicates said information to an external system.

11. The system of claim 1, wherein said DRD stores said information about said RFID tag for later communication to an external system.

12. A method for determining whether a clerk has delivered or picked up an object at a particular collection-unit in a collection station including a plurality of permanently stationary collection-units, wherein the particular collection-unit is assigned to an owner of the object, comprising:

having a radio-frequency identification (RFID) tag in fixed conjunction with the particular collection-unit; and

sensing said RFID tag with a device worn about the hand of the clerk as the object is brought into or taken from proximity with said RFID tag; and

collecting identification information about said RFID tag while in proximity with said RFID tag.

13. The method of claim 12, wherein said RFID tag includes a passive type RFID device.

14. The method of claim 12, wherein said step of sensing occurs as the clerk is handling the object.

15. The method of claim 12, wherein said step of collecting occurs automatically based on occurrence of said step of sensing.

16. The method of claim 12, wherein said step of collecting is triggered by a stimulus additional to occurrence of said step of sensing.

17. The method of claim 16, wherein collecting is triggered by a stimulus including at least one member of the set consisting of detecting a physical action by the clerk, detecting a change in a magnetic field, detecting a change in ambient light, and calculating a position based on a radio signal.

18. The method of claim 12, further comprising time-stamping said identification information.

19. The method of claim 12, further comprising communicating said identification information to an external system.

20. The method of claim 19, further comprising storing said identification information before communicating said identification information to said external system.

21. The method of claim 12, wherein the plurality of collection-units in the collection-station includes an equal or lesser plurality wherein each collection-unit therein has at least one said RFID tag in conjunction therewith, and the method further comprising:

discriminating among all said RFID tags concurrently sensed to select a single said RFID tag that is in fixed conjunction with the particular collection-unit; and

performing said step of collecting for said single said RFID tag.

22. The method of claim 21, wherein said step of performing is performed only for said single said RFID tag.

23. A system for determining whether a clerk has delivered or picked up an object at a particular collection-unit in a collection-station including a plurality of permanently stationary collection-units, wherein the particular collection-unit is assigned to an owner of the object, comprising:

radio-frequency identification (RFID) means embodied in a tag form factor wherein said RFID means is in fixed conjunction with the particular collection-unit; and

means for sensing said RFID means as the object is brought into or taken from proximity with said RFID means, wherein said means for sensing is worn about the hand of the clerk; and

means for collecting identification information about said RFID means while in proximity with said RFID means.

24. The system of claim 23, further comprising means for triggering said means for sensing.

25. The system of claim 23, further comprising means for time-stamping said identification information.

26. The system of claim 23, further comprising means for communicating said identification information to an external system.

27. The system of claim 23, wherein the plurality of collection-units in the collection-station includes an equal or lesser plurality wherein each collection-unit therein has at least one said RFID means in conjunction therewith, and the system further comprising:

means for selecting a single said RFID means that is in fixed conjunction with the particular collection-unit from among all said RFID means concurrently sensed; and

means for controlling said means for collecting to collect said identification information about said single said RFID means.
