Abstract: A vehicle lavatory monument assembly that includes an enclosure having a plurality of walls that cooperate to define a lavatory interior, an entry door, and a toilet positioned in the lavatory interior. The enclosure includes an inlet and the toilet includes an outlet. An air replenishment system is configured to move a first volume of air from the lavatory interior and through the outlet and a second volume of air through the inlet an into the lavatory interior to replenish the air in the lavatory interior.

Abstract: A vehicle lavatory monument assembly that includes an enclosure having a plurality of walls that cooperate to define a lavatory interior, an entry door positioned on one of the plurality of walls, and a UV sanitization system that includes a first light module positioned in the lavatory interior. The first light module includes an ultraviolet light source that emits ultraviolet light rays and a lens member. The UV sanitization system also includes a first reflective surface having a reflective coating thereon, a first direct surface to be sanitized, and a first indirect surface to be sanitized. The lens member is configured to direct ultraviolet light rays to the first direct surface to be sanitized and to direct ultraviolet light rays to the first reflective surface. The first reflective surface is angled to direct ultraviolet light rays to the first indirect surface to be sanitized.

Abstract: A trolley support system (100) includes at least one intelligent trolley (102) designed for use onboard passenger transportation vehicles such as aircraft. The trolley (102) includes a housing (106) with an internal compartment (108) and a door (110) that provides selective access to the internal compartment. The door is movable between a closed position and an unclosed position. The trolley also includes a control sensor (116) that configured to detect at least one characteristic of the trolley and a visual indicator (122) configured to emit a visual transmission based on the at least one detected characteristic. A trolley node (104) having a controller may be included with the trolley and may be communicatively coupled to the control sensor and the visual indicator.
