An automatic drain system may comprise a drain including a neck defining a drain orifice and a flange extending from the neck. A liquid detection sensor is located on at least one of the neck or the flange. A sink assembly may comprise a sink basin and the drain located in a sink opening formed in the sink basin.

A system is provided. The system includes a translucent display positioned such that a first face is a display face and that a second face is a projection face and at least one projector configured to project an image on the second face of the translucent display. The image is displayed on the first face. The system also includes at least one sensor configured to transmit a signal when triggered and a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to receive a signal from the at least one sensor and instruct the at least one projector to project at least one image on the translucent display in response to the signal from the at least one sensor.

The embodiments disclosed herein are directed towards vacuum-assisted toilet systems and methods of using the vacuum-assisted toilet systems. An example vacuum-assisted toilet system includes a toilet bowl defining an outlet and a flush valve fluidly coupled to the outlet. The vacuum-assisted toilet system also includes at least one water source fluidly coupled to the toilet bowl. The water source is configured to supply water to the toilet bowl. The vacuum-assisted toilet system also includes at least one water actuator coupled to the water source. The water actuator is configured to control the amount of water that is supplied by the water source to the toilet bowl. The vacuum-assisted toilet system also includes a controller that is configured to at least partially control the operation of one or more components of the vacuum-assisted toilet system, such as at least one of the flush valve or the water actuator.

An on-board toilet cubicle for an aircraft, including a front long side and a rear long side; a front short side and a rear short side, which are each connected at one end to the front long side and at their other end to the rear long side, the long sides and the short sides enclosing an interior of the on board toilet cubicle, and the front and the rear long sides each being wider than the front and the rear short sides; a toilet unit with a toilet opening; and an L-shaped door for accessing the on-board toilet cubicle, the L-shaped door having one door leg in the front long side and one door leg in the front short side, the toilet unit arranged adjacent to the rear long side, and the door leg in the front long side being wider than the door leg in the front short side.
