Abstract: Systems, methods, and articles of manufacture for controlling a compression action of a trash receptacle of an aircraft lavatory. Generally, the systems, methods, and articles of manufacture disclosed and described herein facilitate controlled opening and closing actuations of a flap of a trash receptacle of an aircraft lavatory, and a compression action after detection of at least the closing actuation of trash deposits in the trash receptacle to increase the interior volume of the trash receptacle. By controlling the closing actuations of the flap and compression actions of trash deposits, hygiene and sanitation of the lavatory are improved, odors are prevented from dispersing throughout the lavatory and/or cabin of the aircraft, and fire hazards are reduced.

Abstract: An oxygen supply system for delivering oxygen to passengers in an aircraft in an event of a loss of cabin pressure includes a source of oxygen, a passenger service unit, and a main controller. The passenger service unit includes a face mask configured to facilitate a flow of an accumulated volume of oxygen from the source of oxygen, and a sensor configured to detect at least one of an ambient pressure, an airflow in a first direction, or an airflow in a second direction. The main controller is configured to determine at least one of the ambient pressure, the airflow being in the first direction, or the airflow being in the second direction, and command delivery of oxygen from the source of oxygen to the face mask in response to the determination.

Abstract: A method for controlling a touchless lavatory is disclosed herein. The method includes forming one or more groups of sensors from a plurality of sensors, determining that a trigger event is detected from the first sensor, and identifying a first group of sensors of the one or more groups of sensors to which the first sensor belongs. The method further includes requesting an ambient light measurement from each of the plurality of sensor. The method further includes computing an average ambient light value based on the ambient light measurement, comparing the ambient light measurement of the first sensor to the average ambient light value of all the sensors, determining that the ambient light measurement of the first sensor is less than the average ambient light value of all the sensors, and determining that the first sensor trigger event is valid.
