Abstract

The present invention is a system and method for determining product movement using a sensor. Through the interaction of items placed on an array of sensors connected to a circuit board controller, the apparatus is configured to detect a change in capacitance caused by the interaction and thereby associate it with an item or groups of items. Detection and association of such signals recorded in a database with items displaced in a storage location permits a user to keep track of said items remotely through a computing device.

Claims

1. An inventory tracking apparatus comprising:

one or more sensor pads which comprise one or more sensors, wherein said sensor pads are configured to detect movement of an item via a change in sensor capacitance caused by an interaction between said sensor and said item;

a controller communicatively connected to said one or more sensor pads; and

a database that receives data from said controller and is configured to generate a signal signature based in part on said change in said sensor capacitance.

2. The inventory tracking apparatus of claim 1, further comprising at least one ground plane.

3. The inventory tracking apparatus of claim 2, wherein said at least one ground plane is a discrete component within each of said sensor pads.

4. The inventory tracking apparatus of claim 2, wherein said at least one ground plane is a shelf.

5. The inventory tracking apparatus of claim 2, wherein at least one of said sensors or said ground planes comprises a conductive layer deposited onto a dielectric layer.

6. The inventory tracking apparatus of claim 1, wherein said one or more sensor pads are substantially planar.

7. The inventory tracking apparatus of claim 1, wherein said one or more sensor pads comprise alternating layers of conductive and dielectric materials.

8. The inventory tracking apparatus of claim 1, wherein said controller comprises a frequency generator.

9. The inventory tracking apparatus of claim 1, wherein said controller is configured to be communicably coupled with other controllers.

10. The inventory tracking apparatus of claim 1, wherein said controller is configured to be communicably coupled with a computer network.

11. The inventory tracking apparatus of claim 1, further comprising a plurality of connectors for power transmission.

12. The inventory tracking apparatus of claim 1, further comprising a plurality of connectors for data transmission.

13. The inventory tracking apparatus of claim 1, further comprising an application server communicably connected to said one or more sensor pads.

14. The inventory tracking apparatus of claim 1, further comprising a multiplexer.

15. A method of inventory tracking comprising the steps of:

detecting a capacitance change when an item is placed on a sensor pad;

generating a signal signature based in part on said capacitance change;

and tracking a movement of said item based in part on a change in said item location indicated by said signal signature.

16. The method of claim 15 further comprising the step of associating said signal signature into a database as an item location for said item.

17. The method of claim 15 wherein all of the steps are repeated after a predetermined period of time.

18. The method of claim 15 further comprising the step of displaying the said movement of said item to a user via a computing device.

19. The method of claim 15 wherein the steps are performed at least in part by an apparatus comprising:

one or more sensor pads which comprise one or more sensors, one or more ground planes, wherein said sensor pads and said ground plane are configured to detect movement of an item via a change in sensor capacitance caused by an interaction between said sensor, said ground plane, and said item;

a controller communicatively connected to said one or more sensor pads; and

a database that receives data from controller and is configured to generate a signal signature based in part on said change in said sensor capacitance.

20. An inventory tracking apparatus comprising a non-transitory, computer readable recording medium containing a computer program, which when executed by a processor, causes the processor to perform the steps of:

detecting a capacitance change when an item is placed on a sensor pad;

generating a signal signature based in part on said capacitance change;

and tracking a movement of said item based in part on a change in said item location indicated by said signal signature.
