Abstract

An air cleaner is provided according to an embodiment of the invention. The air cleaner includes a volatile memory including an air cleaner state memory element and a non-volatile memory including an air cleaner state backup memory element. The air cleaner is configured to store an air cleaner state to the air cleaner state memory element of the volatile memory and store the air cleaner state to the air cleaner state backup memory element of the non-volatile memory.

Claims

1. An air cleaner, comprising:

a volatile memory including an air cleaner state memory element; and

a non-volatile memory including an air cleaner state backup memory element;

wherein the air cleaner is configured to store an air cleaner state to the air cleaner state memory element of the volatile memory and store the air cleaner state to the air cleaner state backup memory element of the non-volatile memory.

2. The air cleaner of claim 1, wherein the air cleaner state is retained in the absence of electrical power.

3. The air cleaner of claim 1, wherein the air cleaner state is stored upon a state change.

4. The air cleaner of claim 1, wherein the air cleaner state is stored upon an operational change.

5. The air cleaner of claim 1, wherein the air cleaner recovers a pre-power cycle air cleaner state.

6. The air cleaner of claim 1, wherein the air cleaner recovers a pre-power loss air cleaner state.

7. The air cleaner of claim 1, with the non-volatile memory comprising a flash memory.

8. The air cleaner of claim 1, further comprising a processing system coupled to the volatile memory and the non-volatile memory, with the processing system being configured to store the air cleaner state to the air cleaner state memory element and store the air cleaner state to the air cleaner state backup memory element.

9. An air cleaner, comprising:

a volatile memory including an air cleaner state memory element;

a non-volatile memory including an air cleaner state backup memory element; and

a processing system coupled to the volatile memory and to the non-volatile memory and configured to store an air cleaner state to the air cleaner state memory element of the volatile memory and store the air cleaner state to the air cleaner state backup memory element of the non-volatile memory.

10. The air cleaner of claim 9, wherein the air cleaner state is retained in the absence of electrical power.

11. The air cleaner of claim 9, wherein the air cleaner state is stored upon a state change.

12. The air cleaner of claim 9, wherein the air cleaner state is stored upon an operational change.

13. The air cleaner of claim 9, wherein the air cleaner recovers a pre-power cycle air cleaner state.

14. The air cleaner of claim 9, wherein the air cleaner recovers a pre-power loss air cleaner state.

15. The air cleaner of claim 9, with the non-volatile memory comprising a flash memory.

16. An air cleaner state backup method, comprising:

storing an air cleaner state to an air cleaner state memory element of a volatile memory; and

storing the air cleaner state to an air cleaner state backup memory element of a non-volatile memory.

17. The method of claim 16, wherein the air cleaner state is retained in the absence of electrical power.

18. The method of claim 16, wherein the air cleaner state is stored upon a state change.

19. The method of claim 16, wherein the air cleaner state is stored upon an operational change.

20. The method of claim 16, wherein the air cleaner recovers a pre-power cycle air cleaner state.

21. The method of claim 16, wherein the air cleaner recovers a pre-power loss air cleaner state.

22. The method of claim 16, with the non-volatile memory comprising a flash memory.
