A trolley (1, 2, 3), e.g. a galley trolley of an aircraft, the trolley (1, 2, 3) having a housing (10, 210, 310) and a compartment (C, 2C, 3C) for the location of goods, the housing (10, 210, 310) comprising walls (11, 11′, 12, 12′, 13, 211, 211′, 212, 212′, 311, 311′, 312, 312′, 313) and a door (14, 214, 214′, 314), at least one of said walls being movable between a first condition where it is proximate the compartment (C, 2C, 3C) and a second condition where it is further from the compartment (C, 2C, 3C).

An acoustic structure presenting a front surface and a back surface is provided. The acoustic structure includes a support layer comprising the back surface, a honeycomb core comprising a thickness defined between a back and a front, and a plurality of walls that define a plurality of honeycomb cells, wherein the plurality of honeycomb cells extend through the thickness of the honeycomb core opening out toward at least the front, and wherein the back of the honeycomb core is affixed to the support layer, a mesh layer affixed to the front of the honeycomb core, and a knit fabric layer affixed to the mesh layer and conforming to the front surface of the acoustic structure.

An integrated hand cleaning system includes a hand cleaning housing including dispensing spout and a sensor. An actuator is operatively connected to the housing. A cleaning substance reservoir is in fluid communication with the dispensing spout. A controller is operatively connected to the sensor and to the actuator. The controller is configured to activate the actuator based on detection of a user's hand by the sensor. A method for controlling a hand cleaning system includes receiving, with a controller, a sensor signal from a sensor in a hand cleaning housing. The method includes activating an actuator of a hand cleaning system with the controller based on the sensor signal.

An in-flight announcement system (500) includes a voice input device (300) that inputs voice, a central control device (100) that translates an announcement content based on the input voice and outputs a modulation signal, a lighting device (400) that emits light based on the input modulation signal, and a receiving terminal (200) that specifies the announcement content based on an input light signal and outputs a translation result. The central control device (100) includes a recognition unit (101) that recognizes the voice information as utterance information, a determination unit (102) that determines whether the utterance information is a fixed sentence or not and outputs identification information of the fixed sentence, a text information group (103) including text information necessary for the determination unit (102) to determine and obtain the identification information, a translation unit (104) that translates the utterance information that is not determined as the fixed sentence and outputs reference information for the translation result, a storage (105) for storing the translation result, a generation unit (106) that generates a data set, a conversion unit (107) that generates the modulation signal based on the data set, and a moving body information management unit (108) that stores various information of an aircraft.

Systems and methods provide technology for wayfinding assistance for visually-impaired passengers, including short-range transmitters distributed within a passenger cabin of an aircraft, a transit vehicle or a vessel, each short-range transmitter located proximate to a respective waypoint in the passenger cabin to transmit a signal identifying the respective waypoint in the passenger cabin, and a client application to, responsive to passing within a range of one of the plurality of short-range transmitters, receive a first transmission from the short-range transmitter and emit one or more of a first audible signal or a first haptic signal, based on the first transmission, as wayfinding assistance to a user of the client device. The technology can also include a mid-range transmitter located proximate to a service area in the passenger cabin, to transmit a signal providing at least one of a status of or a location of the service area.

A thermostat mixing valve for a water temperature control system may comprise a mixing chamber defining a valve outlet, a first proportional solenoid valve fluidly coupled to the mixing chamber, and a second proportional solenoid valve fluidly coupled to the mixing chamber. Each of the first proportional solenoid valve and the second proportional solenoid valve may include a housing assembly defining a fluid inlet and a fluid outlet, a plunger assembly configured to translate relative to the housing assembly, and a coil assembly configured to generate a magnetic field that translates the plunger assembly.

A personal service unit (PSU) includes a housing, a dial, and a flow control ring. The dial is rotatable about the housing. The housing includes a longitudinal axis therethrough and a first end and a second end opposite the first end. The dial includes a helical first portion along an interior wall of the dial. The flow control ring includes a helical second portion along an exterior wall of the flow control ring. The helical second portion rotatably mates with the helical first portion and rotation of the dial in a first direction moves the flow control ring in a first direction along the longitudinal axis to cause a first adjustment in airflow past the flow control ring and rotation of the flow control ring in an opposite direction moves the flow control ring in an opposite direction to cause a second adjustment in airflow past the flow control ring.
