Abstract: A multi-compartment oven provides removable shelves receiving separated streams of heated air providing heating for different oven cavities above and below the shelves. The shelves communicate with an operator automatically closing ducts providing air to the shelves when the shelves are removed.

Abstract: A multi cavity oven provides improved cavity and jet plate cleaning by directing pressurized cleaning spray into the jet plates while installed within the oven through cleaning spray inlet ports in the walls of the removable jet plates. By directing cleaning spray directly into the interior of the jet plates, cooking juices that fall through the slots and openings and into the air passageway of the jet plates can be pressure cleaned and drained from the interior of the jet plates without removing the jet plates from the oven cavity.

Abstract: A method and system for monitoring service quality in a restaurant are disclosed. Multiple sensor modules are installed at each table of a restaurant for detecting restaurant customer service related information. The detected restaurant customer service related information is transmitted, preferably, over-the-air to a central computer unit having a receiver for receiving the detected restaurant customer service related information transmitted by the sensor modules over-the-air. A display monitor, coupled to the central computer unit, can be utilized to display the detected restaurant customer service related information received by the receiver to a restaurant manager in a real-time basis regardless of whether the restaurant manager is present at the restaurant or at a remote location.
