Top level objects communicates with incoming outgoing Graphical Interface/Central Computer Communicates with the door/choke, waveguide, magnetron, and cooking cavity. Incoming messages are from the user (power, timing, etc.), also from the door, which tells the GUI whether the waveguide is safe to activate. Outgoing signals tell the magnetron to begin making the waves, the cooking cavity to spin, displays time on the screen. Door Communicates with the GUI to ensure the microwave can only activate if the door is closed or after engaging the choke. Only incoming message comes from the choke which tells if the door is opened or not. Outgoing signal from the choke tell the door whenever it opens or closes, it inform the GUI which turns off the device when the door opens. Microwave waveguide/magnetron

Unformatted text preview: Communicate with the GUI, door, and choke. Incoming messages from the GUI to either start or stop generating waves, setting the power, and mode.

No outgoing signals The GUI must display the amount of time remaining in each cycle. In addition, it needs to show the user whether the microwave is on or off. The advantage having componentized system is that if one of the internal components breaks, they can be replaced without replacing the entire microwave. (I was unsure as to whether to include the view screen on the door, which allows the user to view the item in the microwave)...

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
