Abstract: An improved exhaust system and method for an apparatus that removes support material from additively manufactured parts is disclosed. The apparatus includes an enclosed chamber in which the additively manufactured parts are placed. A heated detergent fluid is sprayed at the additively manufactured parts. The improved exhaust system exhausts heated air from the chamber. The improved exhaust system includes an exhaust channel having an inlet end open to the chamber through which heated air from the chamber is caused to flow. Relatively cooler air is caused to flow across the outside of the exhaust channel. When the heated air from the chamber encounters the exhaust channel across which the relatively cooler air is caused to flow, evaporated fluids in the heated air condense and fall back into the chamber. The improved exhaust system can be retrofitted onto older models of the support removal apparatus that do not have the improved exhaust system.

Abstract: Systems and methods for providing an enhanced head up display to an aircraft pilot are disclosed. According to a first aspect of the present invention, a system for increasing pilot situational awareness is disclosed. The system includes a navigational component that determines one or more of an aircraft location and attitude. The system also includes a scene generator that produces one or more virtual images of the space into which the aircraft is flying based, at least in part, on the aircraft location and/or attitude. The system further includes one or more head up displays that display the one or more virtual images to facilitate increasing pilot situational awareness. Other systems and methods for providing an enhanced head up display are also disclosed.
