A system controller may provide a shared clock source to multiple illumination peripherals and multiple wearable vision obstruction devices having shutters. The multiple illumination peripherals may selectably turn on and off during different timeslots and the shutters of the multiple wearable vision obstruction devices may selectably occlude and un-occlude vision of users during the different time slots. By modulating the illumination peripherals and the shutters, different users may perceiver different sensory inputs in a shared environment. For instance, users may experience brighter or dimmer illumination, or may experience different types of illumination. One user may view a movie on an LCD screen while the LCD screen appears blank to another user. In this manner, a passenger cabin of an aircraft may provide individualized sensory experiences to different passengers sharing the aircraft cabin.

A method for manufacturing a panel includes forming a path segment on a surface of a substrate from a photoluminescent material. The method further includes overlaying the path segment with an overlay material. The overlay material is configured to render the path segment substantially invisible under an ambient photopic condition and render the path segment visible under an ambient mesopic or scotopic condition.

An air duct system comprising an air duct having a main body, a visible light source, an emitter configured to emit radio frequency waves, and one or more antennas. The main body of the air duct defines a passageway having a reflective inner surface. The visible light source is configured to generate visible light. The visible light source directs the visible light along the reflective inner surface of the air duct. The emitter directs the radio frequency waves along the reflective inner surface of the air duct. The one or more antennas are each connected to a corresponding power harvesting circuit, where the radio frequency waves are received by the one or more antennas and are converted into electrical power by the corresponding power harvesting circuit.

A cabin furnishing element (100) for a cabin, such as a cabin of an aircraft, includes a panel (102) having a panel body. The panel body includes an illumination surface (106) having an illumination zone (110), and defines a lighting recess (112) within the panel body relative to the illumination surface (106). The panel (102) also includes a lighting system (104) having a light source assembly (120) and a light guide (122). The light source assembly (120) and light guide (122) are retained within the lighting recess (112) defined by the panel body. The lighting system (104) is adapted to selectively illuminate a portion of the illumination zone (110).
