Abstract

The invention may be broadly conceptualized as an approach in which a coffeemaker (116) receives a plurality of timer settings from a network and communicates the state of the coffeemaker (116) to another network device while keeping a real-time clock (1112) synchronized and correctly set by receiving period time synchronization messages.

Claims

1. An apparatus, comprising:

a coffeemaker;

a clock with a plurality of timers;

a controller with a communication path to the clock; and

a network interface connected to the communication path in receipt of a plurality of timer settings that are set in the clock by the controller that controls the coffeemaker;

wherein the controller is configured to form a message containing a state of the coffeemaker apparatus, and the network interface transmits the state message from the network interface for reception by another device.

2. The apparatus of claim 1, wherein the state of the coffeemaker is a not ready state upon the plurality of timer settings being set.

3. The apparatus of claim 2, further comprising:

a button that when selected results in the state of the coffeemaker being in a ready to brew state.

4. The apparatus of claim 3, wherein a brew timer is set upon a time kept by the clock matching one of the plurality of timer settings and results in the state of the coffeemaker apparatus being in a brewing state.

5. The apparatus of claim 4, further comprising:

a warming plate that is turned off upon the expiration of a warming timer that is set upon the expiration of the brew timer and results in the state of the coffeemaker being a coffee ready state.

6. The apparatus of claim 1, further comprising:

a memory that stores the plurality of timer settings.

7. The apparatus of claim 1, wherein a time synchronization message having a time that is received by the network interface and results in the clock being set to the time in the time synchronization message.

8. The apparatus of claim 1, further comprising:

a display in communication with the clock over the communication path that displays a time on the display.

9. The apparatus of claim 1, further comprising:

a display in communication with the controller over the communication path that displays the state of the coffeemaker.

10. A method, comprising:

receiving at a coffeemaker apparatus with a network interface at least one timer setting at the network interface;

setting a clock with the at least one timer setting;

setting a state of the coffeemaker apparatus;

formatting a state message containing the state;

transmitting the state message from the network interface for reception by another device; and

;

controlling the coffeemaker apparatus based on the state of the coffeemaker apparatus.

11. The method of claim 10, wherein setting the state further includes:

setting the state of the coffeemaker apparatus to a not ready state upon the setting of the clock with the at least one timer settings.

12. The method of claim 10, wherein setting the state further includes:

signaling from an input device on the coffeemaker apparatus; and

setting the state of the coffeemaker apparatus to a ready to brew state in response to the signaling of the input device.

13. The method of claim 10, wherein setting the state further includes:

identifying that the clock has reached the at least one timer settings;

initializing a brew timer to a predetermined time value; and

setting the state of the coffeemaker apparatus to a brewing state.

14. The method of claim 13, wherein setting the state further includes:

identifying that brew timer has expired;

setting a warming timer in response to the brew timer expiring; and

changing the state of coffeemaker apparatus to a coffee ready state.

15. The method of claim 14, wherein setting the state further includes:

identifying that the warming timer has expired; and

changing the state of the coffeemaker apparatus to a not ready state in response to the expiration of the warming timer.

16. The method of claim 14, further including:

deactivating a warming plate in response to expiration of the warming timer.

17. The method of claim 10, further comprising:

displaying on a display a time from the clock.

18. The method of claim 10, further comprising:

displaying on a display a state of the coffeemaker appliance.

19. The method of claim 10, further comprising:

receiving a time synchronization message at the network interface of the coffeemaker appliance; and

setting the clock in response to the time synchronization message.

20. An apparatus, comprising:

means for receiving at a coffeemaker apparatus at least one timer setting at the network interface;

means for setting a clock with the at least one timer setting;

means for setting a state of the coffeemaker apparatus;

means for formatting a state message containing the state for reception by another device;

means for transmitting the state message and;

means for controlling the coffeemaker apparatus based on the state of the coffeemaker apparatus.

21. The apparatus of claim 20, wherein the means for setting the state further includes:

means for setting the state of the coffeemaker apparatus to a not ready state upon the setting of the clock with the at least one timer settings.

22. The apparatus of claim 20, wherein the means for setting the state further includes:

means for signaling from an input device on the coffeemaker apparatus; and

means for setting the state of the coffeemaker apparatus to a ready to brew state in response to the input device.

23. The apparatus of claim 20, wherein the means for setting the state further includes:

means for identifying that the clock has reached the at least one timer settings;

means for initializing a brew timer to a predetermined time value; and

means for setting the state of the coffeemaker apparatus to a brewing state.

24. The apparatus of claim 23, wherein the means for setting the state further includes the steps of:

means for identifying that brew timer has expired;

means for setting a warming timer in response to the brew timer expiring; and

means for changing the state of coffeemaker apparatus to a coffee ready state.

25. The apparatus of claim 24, wherein the means for setting the state further includes the steps of:

means for identifying that the warming timer has expired; and

means for changing the state of the coffeemaker apparatus to a not ready state in response to the expiration of the warming timer.

26. The apparatus of claim 24, further including:

means for deactivating a warming plate in response to expiration of the warming timer.

27. The apparatus of claim 20, further comprising:

means for displaying on a display a time from the clock.

28. The apparatus of claim 20, further comprising:

means for displaying on a display a state of the coffeemaker appliance.

29. The apparatus of claim 20, further comprising:

means for receiving a time synchronization message at the network interface of the coffeemaker appliance; and

means for setting the clock in response to the time synchronization message.
