A mmWave radar sensing system is operatively connected to the controller to indicate user presence. The controller includes machine readable instructions configured to verify gesture input from the gesture sensing system using input from the mmWave radar sensing system before controlling the actuator to open or close the lavatory door.

Abstract: A galley insert system for an aircraft galley comprises a galley support structure, a galley insert configured to be coupled to the support structure, and a latch mechanism for coupling the insert to the support structure, the latch mechanism configured to automatically engage to couple the insert to the support structure when the insert is moved into a latching position on the support structure, wherein the latch mechanism comprises a control mechanism configured to be actuated to disengage the latch mechanism.

Abstract: A steam oven for a mobile platform (e.g., sized for a galley insert in an aircraft galley) injects water into the oven cavity to generate steam. The water is injected as a horizontal jet over a fan and into an opposing baffle plate, where a portion is heated on contact and immediately evaporates into steam. The steam is then distributed throughout the oven cavity by the fan. The unevaporated portion is drawn downward into the fan, where it too is distributed throughout the oven cavity rather than collecting on the cavity floor. Rather than building up within the injector, scale accumulates on the baffle plate where it may easily be cleaned or removed.

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 ducting assembly, apparatus and method of manufacture is provided. The assembly includes a housing, and a duct inside the housing for channeling outside air from an inlet of the duct to an outlet of the duct to a fan of a micro-chiller unit. The duct is configured with a variable parametric three-dimensional (3D) shape to discretely reverse a flow of the outside air as the outside air is channeled inside the duct. The outside air is received, in a first direction at the inlet of the duct through a first stage of the duct that expands airflow of the outside air inside the duct and then is discretely reversed, in a second direction by the variable parametric 3D shape to flow to the outlet of the duct through a second stage that constricts the airflow of the outside air inside the duct to reduce maldistribution of air.
