Abstract

A filter assembly is provided for an appliance that performs a useful cycle of operation on a physical article and uses a resource that passes through the filter assembly. The filter assembly includes at least one replaceable filter mounted in a filter holder. The filter holder has at least one control board having software architecture configured for communication on a network including other control boards or clients. The control board has at least one functionality of a universe of functionalities, and the functionality has a unique identifier, where the unique identifier can be communicated by the software architecture over the network. The filter assembly has at least one node in communication with the network, so that the filter assembly can monitor and record events, communicate, or affect the cycle of operation of the appliance.

Claims

1. A filter assembly for an appliance that performs a useful cycle of operation on a physical article and uses a resource that passes through the filter assembly, the filter assembly comprising at least one replaceable filter mounted in a filter holder, comprising:

at least one control board having software architecture configured for communication on a network including other control boards or clients, and the at least one control board having at least one functionality of a universe of functionalities;

the at least one functionality having a unique identifier, wherein the unique identifier can be communicated by the software architecture over the network;

a memory containing information associated with the at least one replaceable filter and configured for communication to the appliance in at least one message over the network, wherein the information includes data comprising a separated cycle structure portion and having a description of an ordered collection of steps, actions to be taken by at least one component of the appliance during each step, and conditions under which a current step should transition into a next step in the ordered collection of steps; and

the filter assembly having at least one node in communication with the network, wherein the appliance can build the useful cycle of operation based on the information upon receipt of the at least one message, and perform the built operation cycle related to the at least one replaceable filter.

2. The filter assembly of claim 1 wherein the network is a first network and the filter assembly comprises a network communication device configured to propagate and transfer information between the appliance and at least one additional network which is not the first network.

3. The filter assembly of claim 2 wherein the network communication device comprises means to effect two way communication.

4. The filter assembly of claim 1 wherein the information comprises at least one of additional cycles of operation, updated cycles of operation, historical information relating to cycles of operation experienced by the appliance, and software to reconfigure the software architecture.

5. The filter assembly of claim 1 wherein the filter holder is configured to query the communication network for the unique identifiers of the functionalities in the appliance.

6. The filter assembly of claim 1 wherein the network is in the appliance and the filter assembly forms a node on the network.

7. The filter assembly of claim 1 wherein functionality in the appliance is configurable by the message from the filter assembly.

8. The filter assembly of claim 7 wherein the message assigns the unique identifier to a new functionality.

9. The filter assembly of claim 1 wherein the communication is wireless and two-way.

10. The filter assembly of claim 1 configured for use in a refrigerator.

11. The filter of claim 1 further comprising an identifying element wherein the unique identifier is stored in the identifying element.

12. The filter of claim 11 wherein the identifying element also has an algorithm for determining characteristics of the filter or the fluid.

13. The filter of claim 11 further comprising a filter status indicator.

14. A filter assembly comprising

a filter holder disposed to hold a filter in a fluid path;

a filter disposed in the filter holder in the fluid path;

at least one appliance coupling point configured to direct fluid from the fluid path downstream of the filter to an appliance configured to use the fluid;

a source of information associated with one of the filter holder, the filter, and the fluid and configured for communication to the appliance in at least one message, wherein the information includes data comprising a separated cycle structure portion and having a description of an ordered collection of steps, actions to be taken by at least one component of the appliance during each step, and conditions under which a current step should transition into a next step in the ordered collection of steps; and

a circuit with at least one control board having software architecture configured for communication on a network including other components connected to the circuit, including the at least one component in the appliance, the circuit being configured to retrieve the information from the source of information;

whereby the circuit can communicate the information over the network when the filter assembly is coupled to the appliance and the appliance can build a cycle of operation based on the information, and perform the built operation cycle related to the one of the filter holder, the filter, and the fluid.

15. The filter assembly of claim 14 wherein the at least one appliance coupling point is the filter holder.

16. The filter assembly of claim 14 wherein the software architecture enables two-way communication over the network.

17. A filter for an appliance that performs a useful cycle of operation on a physical article and uses a resource that passes through the filter, comprising:

at least one functionality from a universe of functionalities, the at least one functionality having a unique identifier, and

a circuit with at least one control element having software architecture configured for communication on a network including other components connected to the circuit, including at least one component in an appliance, the circuit being configured to communicate the unique identifier over a network, and

a memory containing information associated with the filter and configured for communication in at least one message over the network, wherein the information includes data comprising a separated cycle structure portion and having a description of an ordered collection of steps, actions to be taken by at least one component of the appliance during each step, and conditions under which a current step should transition into a next step in the ordered collection of steps;

whereby the circuit can monitor events concerning the filter or the resource, and communicate the information from the memory, wherein the appliance can build the useful cycle of operation based on the information, and perform the built operation cycle related to the filter.

18. The filter of claim 17 wherein the circuit is configured to query the communication network for the unique identifiers of the functionalities in an appliance.

19. The filter of claim 17 wherein functionality in an appliance is configurable by a message from the filter.

20. The filter of claim 17 wherein the communication is wireless and two-way.

21. The filter of claim 17 wherein the circuit communicates to the appliance information about the characteristics of the filter when the filter is coupled to the appliance.
