Abstract

The present invention is a system and method for determining product movement using a sensor. Through the interaction of a body or items placed near to or 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 a movement or placement of 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 each of a proximity, presence, absence, movement, placement, or removal of an item or a body via a change in sensor capacitance caused by an interaction between said sensor and said item or said sensor and said body respectively;

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 circuit.

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

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

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

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

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

8. The inventory tracking apparatus of claim 1, said one or more sensors are configured to operate as a ground circuit when inactive.

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

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

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

detecting a capacitance change when an item is placed or moved on a sensor pad, when a body comes in proximity to said sensor pad, moves relative to said sensor pad after having come in proximity to said sensor pad, or interacts with an item located on or in proximity to said sensor pad;

generating a signal signature representative of and based at least in part on said capacitance change; and

tracking a movement of said item or said body respectively based in part on a respective change in said item'"'"'s or said body'"'"'s location indicated by said signal signature.

12. The method of claim 11 further comprising a step of associating said signal signature into a database with an action or state of which it is indicative.

13. The method of claim 11 wherein all of the steps are repeated after a predetermined period of time.

14. The method of claim 11 further comprising the step of displaying said proximity, presence, absence, movement, placement, or removal of said item or body to a user via a computing device.

15. The method of claim 11 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 one or more sensor pads and said one or more ground planes are configured to detect the proximity, presence, absence, movement, placement, or removal of an item or a body via a change in sensor capacitance caused by an interaction between said sensor, said ground plane, and said item or body respectively;

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;

wherein said one or more sensor pads comprise a plurality of pairs of alternating layers of conductive and dielectric materials; and

said controller comprises said electrical frequency generator.

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

detecting a capacitance change when an item is placed or moved on a sensor pad, when a body comes in proximity to said sensor pad, moves relative to said sensor pad after having come in proximity to said sensor pad, or interacts with an item located on or in proximity to said sensor pad;

generating a signal signature representative of and based at least in part on said capacitance change; and

tracking a movement of said item or said body respectively based in part on a change in said item'"'"'s or said body'"'"'s location respectively indicated by said signal signature;

wherein the steps are performed at least in part by an apparatus comprising;

one or more sensor pads which comprise one or more sensors configured to operate as part of a ground circuit when inactive, wherein said sensor pads are configured to detect each of a proximity, presence, absence, movement, placement, or removal of an item or a body via a change in sensor capacitance caused by an interaction between said sensor and said item or said sensor and said body respectively;

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.

17. The method of claim 16 further comprising a step of associating said signal signature into a database with an action or state of which it is indicative.

18. The method of claim 16 wherein all of the steps are repeated after a predetermined period of time.

19. The method of claim 16 further comprising the step of displaying said proximity, presence, absence, movement, placement, or removal of said item or body to a user via a computing device.
