Abstract

An inventory control system includes an inventory control probe, inventory control module, a docking station, a collar clip, and an inventory control collar used on a storage container. The inventory control collar includes a first conductive ring exposed on the top of the collar electrically connected to a memory and a second conductive ring exposed on the top of the collar and electrically connected to the memory. The inventory control probe includes a probe tip and a first pair of contact pins disposed on the probe tip at a predetermined distance apart such that the contacts concurrently contact the conductive rings of the inventory control collar. A probe body housing is connected at a first end to the probe tip, and a pair of data transfer terminal contacts are disposed on a bottom portion of the probe body housing. A handle is connected at a second end to the probe body housing. The inventory control module includes a control module housing, a pair of data transfer terminal contacts disposed on a bottom portion of the control module housing for engaging the pair of data transfer terminal contacts disposed on the docking station housing, a microprocessor, and a memory. Both the probe and control module can connect to the docking station.

Claims

1. An inventory control probe for reading and writing data to and from an inventory control collar for use on a storage container, the inventory control collar having a first conductive ring exposed on the top of the collar and electrically connected to a resident memory;

and a second conductive ring exposed on the top of the collar spaced from the first ring and electrically connected to the resident memory, the inventory control probe comprising;

a probe tip;

a pair of contact pins disposed on the probe tip at a predetermined distance apart such that the contact pins are configured to concurrently contact the conductive rings of the inventory control collar when the probe tip is removably engaged with the control collar;

a microprocessor for reading and writing data to and from the resident memory of the inventory control collar;

a memory for storing such data;

a probe body housing connected at a first end to the probe tip;

a pair of data transfer contacts disposed on the probe body housing; and

a handle connected at a second end to the probe body housing remote from the probe tip, the handle having a configuration suitable for hand placement of the probe into engagement with the collar.

2. The inventory control probe of claim 1 further including:

a plurality of indicators connected to the microprocessor for indicating operation modes wherein the operating modes include a first mode in which probe identification information matches identification information read from the collar, a second mode in which probe identification information fails to match identification information read from the collar, and a third mode indicating failure of the probe to contact the resident memory of the collar.

3. The inventory control probe of claim 1 further including:

an external connector for a physical link to a host computer.

11. The inventory control probe of claim 1, wherein the probe further comprises a power source for energizing the microprocessor.

12. The inventory control probe of claim 1, wherein the contact pins project from the probe tip and are configured to engage first and second conductive rings which are concentric with the collar and each other such that one of such rings has a greater diameter than the other, the collar being configured to fit onto a neck of the storage container.

13. The inventory control probe of claim 1, wherein the data transfer contacts are disposed on a bottom portion of the probe body housing.

14. The inventory control probe of claim 1, wherein the probe further comprises means for manually activating the probe.

15. The inventory control probe of claim 1, wherein the probe further comprises a power source for energizing the microprocessor, means accessible on the body housing for manually activating the probe, and a terminal separate and differently configured from the contact pins and the data transfer contacts for connecting the probe to a host computer.

16. The inventory control probe of claim 1, wherein the probe body housing is movably connected at the first end to the probe tip.

17. The inventory control probe of claim 1, wherein the probe tip has a frontwardly facing C-shaped portion, wherein the contact pins extend downwardly at spaced positions from an upper wall of the C-shaped portion, the C-shaped portion being configured for conforming engagement with the collar in a manner that brings the contact pins into contact with the first and second conductive rings.

4. An inventory control docking station for transferring data and program instructions to and from an inventory control module or an inventory control probe and an inventory control collar for use on a storage container, the inventory control collar having a first conductive ring exposed on a top of the collar and electrically connected to a resident memory and a second conductive ring exposed on the top of the collar and electrically connected to the resident memory, the inventory control docking station comprising:

a collar clip;

a first pair of contact pins disposed on a collar clip tip at a predetermined distance apart such that the contact pins may concurrently contact the conductive rings of the inventory control collar when the collar clip is removably clipped onto the collar;

a docking station housing connected by an electrical conductor to the collar clip, the docking station housing defining a socket into which a control module can be inserted and removed; and

a pair of data transfer terminal contacts disposed on the docking station housing facing the socket so that corresponding terminals on a control module come into contact with the data transfer terminal contacts upon insertion into the socket.

5. The docking station of claim 4 further including:

an external data transfer connector for a physical link to a host computer.

6. The docking station of claim 4 further including:

an external data transfer connector for a physical link to an input bar code reader.

7. The docking station of claim 4 further including:

an external connector for one analog input, two digital inputs and two relay outputs.

8. The docking station of claim 4 further including:

an external connector for a power supply.

9. The docking station of claim 4, further including:

a control module for reading and writing data to and from the inventory control collar via the inventory control docking station and the collar clip the control module comprising;

a control module housing configured to fit into the socket of the docking station;

a pair of data transfer terminal contacts disposed on the control module housing for engaging the pair of data transfer terminal contacts disposed on the docking station body housing;

a microprocessor for reading and writing data to and from the resident memory of the inventory control collar; and

a memory for storing such data.

10. The control module of claim 9 further including:

an internal connector for a physical link to a network interface module.

18. The docking station of claim 4, wherein the electrical conductor further comprises an interconnecting line having a length sufficient to permit the docking station housing to be located at a location remote from the clip.

19. The docking station of claim 4, wherein the docking station housing comprises a base having the data transfer terminal contacts exposed thereon and a retaining arm for holding a control module inserted into the socket in contact with the data transfer terminal contacts.

20. The docking station of claim 4, wherein the clip is substantially C-shaped and the contact pins extend outwardly at spaced positions from the tip of the C-shaped clip, the C-shaped clip being configured for engagement with the collar in a manner that brings the contact pins into contact with the first and second conductive rings.

21. The docking station of claim 9, wherein the control module further comprises a plurality of indicators connected to the microprocessor of the control module for indicating operation modes, including a first mode wherein control module identification information matches identification information read from the collar, a second mode wherein control module identification information fails to match identification information read from the collar, and a third mode indicating failure of the control module to contact the resident memory of the collar.
