Abstract

An appliance includes an external communication port, such as an RJ45 port, and a wireless communication module in wireless communication with a remote server through an external network. In addition, a controller includes a boot loader segment and is configured to receive a request to access the boot loader segment of the controller, transmit a notification of the request to the remote server using the wireless communication module, receive an access determination from the remote server, e.g., such as an access authorization or denial from an owner, and regulate access to the boot loader segment based at least in part on the access determination.

First claim

What is claimed is:

1. An appliance comprising:
a cabinet;
an external communication port positioned on the cabinet;
a wireless communication module in wireless communication with a remote server through an external network; and
a controller comprising a boot loader segment and being in operative communication with the external communication port and the wireless communication module, the controller being configured to:
detect port activity at the external communication port, the port activity being associated with a request to access the boot loader segment of the controller;
transmit a notification of the request to the remote server using the wireless communication module;
receive an access determination from the remote server; and
regulate access to the boot loader segment through the external communication port based at least in part on the access determination.

2. The appliance of claim 1 , wherein the external communication port is an RJ45 port.

3. The appliance of claim 1 , wherein the controller is in operative communication with a remote device through the external network, and wherein the access determination is communicated from the remote device.

4. The appliance of claim 1 , wherein the access determination comprises at least one of an access authorization or an access denial.

5. The appliance of claim 4 , wherein the access determination is the access authorization, and wherein regulating access to the boot loader segment comprises:
unlocking the boot loader segment of the controller to permit a firmware update.

6. The appliance of claim 5 , wherein regulating access to the boot loader segment further comprises:
relocking the boot loader segment of the controller to prevent the firmware update after a predetermined amount of time has passed since the boot loader segment was unlocked.

7. The appliance of claim 4 , wherein the access determination is the access denial, and wherein regulating access to the boot loader segment comprises:
locking the boot loader segment of the controller and preventing programming of the controller.

8. The appliance of claim 1 , wherein the controller is further configured to:
provide an owner notification regarding the request to access.

9. The appliance of claim 8 , further comprising:
a user interface panel, wherein the owner notification is provided through the user interface panel.

10. The appliance of claim 8 , wherein the controller is in operative communication with a remote device through the external network, and wherein the owner notification is provided through the remote device.

11. The appliance of claim 1 , wherein the controller further comprises an operating software segment, wherein the boot loader segment is configured to modify the operating software segment.

12. The appliance of claim 1 , wherein the appliance is a washing machine appliance, a dryer appliance, or a combination washer/dryer appliance.

13. A method of operating an appliance, the appliance comprising an external communication port, a wireless communication module in wireless communication with a remote server through an external network, and a controller comprising a boot loader segment, the method comprising:
detecting port activity at the external communication port, the port activity being associated with a request to access the boot loader segment of the controller;
transmitting a notification of the request to the remote server using the wireless communication module;
receiving an access determination from the remote server; and
regulating access to the boot loader segment through the external communication port based at least in part on the access determination.

14. The method of claim 13 , wherein the external communication port is an RJ45 port.

15. The method of claim 13 , wherein the access determination comprises at least one of an access authorization or an access denial.

16. The method of claim 15 , wherein the access determination is the access authorization, and wherein regulating access to the boot loader segment comprises:
unlocking the boot loader segment of the controller to permit a firmware update.

17. The method of claim 15 , wherein the access determination is the access denial, and wherein regulating access to the boot loader segment comprises:
locking the boot loader segment of the controller and preventing programming of the controller.

18. The method of claim 13 , further comprising:
providing an owner notification regarding the request to access.

19. The method of claim 18 , wherein the appliance further comprises:
a user interface panel, wherein the owner notification is provided through the user interface panel.

20. The method of claim 18 , wherein the controller is in operative communication with a remote device through the external network, and wherein the owner notification is provided through the remote device.
