Abstract

A resource constrained device is disclosed which includes a tag reader, e.g., an RFID or barcode reader, a communication unit that can communicate information read from the tags to an information interface, and a controller. The controller is arranged to send the information to the information interface via the communication unit. The information interface returns a response, e.g., comprising an XML document. The response is used by the controller to adjust operational parameters which modify the performance of an operational unit, e.g., a washing machine.

Claims

1. An apparatus comprising:

a label reader capable of reading information from a label;

a communication unit capable of communicating with a first information interface having an index and/or one or more other information interfaces;

an operation unit having one or more adjustable operational parameters associated with one or more operation profiles; and

a controller, coupled to the label reader, the communication unit and the operation unit, arranged to (1) receive information from the label reader, (2) send a request to the first information interface and/or one or more other information interfaces through the communication unit, (3) receive a response from one or more information interfaces, and (4) adjust the operation parameters of the operation unit in accordance with the response,

wherein the request and the response are formatted as documents capable of being exchanged in a distributed, decentralized environment.

2. The apparatus according to claim 1, wherein the apparatus and the information interface communicate in a client/server network.

3. The apparatus according to claim 2, wherein the documents comprise XML documents.

4. The apparatus according to claim 3, wherein the XML documents are expressed as SOAP messages.

5. The apparatus according to claim 1, wherein the operation unit comprises a consumer product-type apparatus.

6. The apparatus according to claim 1, further comprising a context sensor coupled to the controller.

7. The apparatus according to claim 1, wherein the one or more information interface respond by sending a profile associated with label information contained within the request from the apparatus.

8. The apparatus according to claim 1, wherein the label reader comprises an RFID reader or a barcode reader.

9. The apparatus according to claim 1, wherein the index is a directory of other information interfaces and allows operation profiles to be added, as needed, which can support additional tags.

10. An apparatus comprising:

a memory; and

a processor coupled to the memory and operative to read information from a tag, communicate with a first information interface having an index and/or one or more other information interfaces, receive a response from the one or more information interfaces, and adjust one or more operational parameters of an operation unit in accordance with the response,

wherein the request and the response are formatted as documents capable of being exchanged in a distributed, decentralized environment.

11. The apparatus according to claim 10, wherein the apparatus and the information interface communicate in a client/server network.

12. The apparatus according to claim 11, wherein the documents comprise XML documents.

13. The apparatus according to claim 12, wherein the XML documents are expressed as SOAP messages.

14. The apparatus according to claim 11, wherein the information interface responds by sending a profile associated with label information contained within the request from the apparatus.

15. The apparatus according to claim 12, further comprising a micro XML parser.

16. The apparatus according to claim 10, wherein the operation unit comprises a consumer product apparatus.

17. The apparatus according to claim 10, further comprising a context sensor coupled to the controller.

18. The apparatus according to claim 10, wherein the tag comprises an RFID or barcode tag.

19. A resource constrained device comprising:

means for reading tags;

communication means for communicating information read from the tags to a remote device;

receiving means for receiving a response comprising an XML document from the remote device, the receiving means including a micro XML parser;

operational means for performing a task, the operational means including adjustable operational parameters modifying the performance of the task;

wherein the adjustable operational parameters are adjusted in accordance with the received response.

20. The device according to claim 19, wherein said means for reading comprises an RFID or barcode reader.
