Abstract: A cooking exhaust hood system, that has an exhaust hood adapted to be located over at least one cooking appliance and an exhaust fan connected to the exhaust hood, with the exhaust fan having a controllable exhaust air flow volume. A camera monitors a surface of the at least one cooking appliance and provide an image signal representing a visual status of the at least one cooking appliance. An image processing controller is connected to an image database and is configured to receive the image signal and to compare the visual status of the at least one cooking appliance based on the image signal to stored images in the image database. The image processing controller then output a cooking appliance status signal. An exhaust fan controller is provided that is connected to the exhaust fan. The exhaust fan controller is configured to receive the cooking appliance status signal and adjusts the exhaust fan accordingly.

The stool includes a main body, one or more engaging elements, and a locking mechanism. The main body has a top surface and a front surface, the top surface being a step surface. The one or more engaging elements extend rearwardly from the main body. The locking mechanism is in mechanical connection with the one or more engaging elements and is for selectively locking the one or more engaging elements in an engagement position with the raised base portion of the structure, whereby the stool is prevented from tipping when the one or more engaging elements are in the engagement position.
