Abstract
An appliance and methods for operating the appliance in a safety-critical operation are provided. The appliance and methods for operating the appliance include features that provide safe and intuitive ways to initiate and cancel safety-critical operations performed by the appliance.
Claims19
An appliance, comprising:
- one or more operational components configured to perform a safety-critical operation;
- a control system for operating the appliance in the safety-critical operation, the control system comprising:
- a main controller;
- a user interface panel comprising a first user control and a second user control;
- a microprocessor communicatively coupled with the main controller and the first user control, the microprocessor configured to:
- receive a first initiation signal from the first user control to initiate the safety-critical operation;
- a microcontroller communicatively coupled with the main controller and the second user control, the microcontroller configured to:
- receive a second initiation signal from the second user control to initiate the safety-critical operation;
- wherein the main controller is configured to:
- receive, in response to the first initiation signal received at the microprocessor, a first activation signal from the microprocessor;
- receive, in response to the second initiation signal received at the microcontroller, a second activation signal from the microcontroller;
- and
- activate, upon receiving the first activation signal and the second activation signal, the one or more operational components to operate the appliance in the safety-critical operation.

A method for operating an appliance in a safety-critical operation, the method comprising:
- receiving a first initiation signal at a microprocessor in response to a first user input of a first user control of a user interface panel of the appliance;
- receiving, in response to the first initiation signal, a first activation signal at a main controller;
- activating, in response to receiving the first activation signal at the main controller, a second user control of the user interface panel;
- receiving a second initiation signal at a microcontroller in response to a second user input of the second user control;
- receiving, in response to the second initiation signal, a second activation signal at the main controller;
- and
- activating, upon receiving the first activation signal and the second activation signal, one or more operational components to operate the appliance in the safety-critical operation.
