Abstract

An electronic storage device is coupled with a container capable of holding liquid for electronically storing information relating to the liquid stored in the container. The system can be configured with an antenna, for storing information to and reading information from the electronic storage device. A microprocessor-based controller, coupled with the antenna, may be employed for controlling processing of the liquid based on information read from the electronic storage device by the antenna. A connector of a secure reader system having a reader is provided to physically couple to a container having an information storing mechanism, for periodically reading information from an information storing mechanism. The connector may draw material from the container simultaneous with the reading.

Claims

1. A system comprising:

a control unit configured to control dispensing of one or more materials from one or more of a plurality of containers to be used in an application; and

a cabinet configured to receive one of a plurality of containers in each of a plurality of locations within the cabinet, wherein;

each container of the plurality of containers is configured to hold a material and comprises a cap and an information storage device stored in or on the cap, the information storage device storing information regarding the material stored within the container, wherein the cap comprises a rupturable membrane sealing the material within the container until the information read from the information storage device indicates that the material stored in the container is suitable for the application; and

each of the plurality of locations is designated to receive one of the plurality of containers that holds a particular material for use in the application, wherein each location of the plurality of locations further includes;

a connector configured to receive the material stored in the container received at the location, wherein the connector comprises a probe which penetrates the rupturable membrane of the cap when the information read from the information storage device indicates that the material stored in the container is suitable for the application; and

a communication assembly configured to read the information about the material stored in the container received at the location and to communicate the information to the control unit, wherein the control unit only permits transfer of the material stored in any of the plurality of containers when the information read from the information storage device indicates that the material stored in the container is suitable for the application.

2. The system of claim 1, wherein the probe comprises a flow passage.

3. The system of claim 2, further comprising a pump coupled with the probe and the flow passage for pumping the material through the probe and the flow passage when the information read from the information storage device indicates that the material stored in the container is suitable for the application.

4. The system of claim 1, wherein the information comprises a material type of the material held in the container.

5. The system of claim 1, wherein the information stored in the information storage device associated with container further includes one or more material properties including at least one of:

a viscosity of the material;

a change in the viscosity of the material over time;

a viscosity of the material at a point in time; and

an age of the material.

6. The system of claim 1, wherein the information storage device associated with each of the plurality of containers comprises a radio frequency identification device.

7. The system of claim 1, Wherein the information storage device associated with each of the plurality of containers comprises a bar code.

8. The system of claim 1, wherein the information storage device associated with each of the plurality of containers comprises an electronic information storage element.

9. The system of claim 1, further comprising an indicator positioned adjacent to the connector at each of the plurality of locations, wherein the indicator is operably coupled to the control unit, and wherein the indicator is configured to generate art indication representing whether the material held in the container includes the particular acceptable material for use in the application.

10. The system of claim 1, wherein the control unit includes a host computer system.

11. The system of claim 1, wherein the communication assembly comprises an antenna.

12. The system of claim 1, wherein the connector is simultaneously coupled to a process assembly to employ the material in the application and the control unit to direct the application.

13. The system of claim 12, wherein the communication assembly comprises an RFID reading device and in response to the information read from the information storage device by the RFID reading device generates a visual output indicative of whether or not the material in the container is suitable for the application and should be transferred from the container to the process assembly.

14. A system comprising:

a control unit configured to control dispensing of one or more materials from one or more of a plurality of containers to be used in an application, wherein;

each container of the plurality of containers is configured to hold a material and comprises a cap and an information storage device located on in or in the cap, the information storage device storing information regarding the material stored within the container, wherein the cap comprises a rupturable membrane sealing the material within the container until the information read from the information storage device indicates that the material stored in the container is suitable for the application; and

each of a plurality of locations is designated to receive one of the plurality of containers that holds a particular material for use in the application, wherein each location of the plurality of locations further includes;

a connector configured to receive the material stored in the container received at the location, the connector comprising a probe which penetrates the rupturable membrane of the cap when the information read from the information storage device indicates that the material stored in the container is suitable for the application; and

a communication assembly configured to read the information about the material stored in the container received at the location and to communicate the information to the control unit, wherein the control unit only permits transfer of the material stored in any of the plurality of containers when the information read from the information storage device indicates that the material stored in the container is suitable for the application.

15. The system of claim 14, wherein he information comprises a material type of the material held in the container.

16. The system of claim 14, wherein the information stored in the information storage device associated with container further includes one or more material properties including at least one of:

a viscosity of the material;

a change in the viscosity of the material over time;

a viscosity of the material at a point in time; and

an age of the material.

17. The system of claim 14, wherein the information storage device associated with each of the plurality of containers comprises a radio frequency identification device.

18. The system of claim 14, wherein the information storage device associated with each of the plurality of containers comprises a bar code.

19. The system of claim 14, wherein the information storage device associated with each of the plurality of containers comprises an electronic information storage element.

20. The system of claim 14, wherein the control unit includes a host computer system.
