Abstract: 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.

Abstract: A self-disinfecting passenger control unit (PCU) includes a transparent or translucent molded or injected polycarbonate layer fused between inner and outer films, the outer film divided into contact surfaces (e.g., for passenger control of lights, call buttons, seats, and other functions) and the inner film including embedded traces. Within the molded polycarbonate layer are embedded LED units configured for continuous near-ultraviolet (near-UV) emission (e.g., at or near 405 nm), providing a uniform luminous output directed at the outer film and capable of antiviral/antibacterial irradiation of the high-touch contact surfaces of the outer film. As the continuous near-UV output is both visible by, and safe for, passengers, the LED units may double as backlighting for guiding passengers to the correct contact surface for adjusting a desired cabin function.

Abstract: A user interface display may have a display and may have a backlight that lights the display. The display may implement pixels to generate colors and images. The display may be backlit. The backlight may use pixels having emitters to generate different color backlighting. In various instances, the display or the backlight or both may include a deep blue emitter. The blue emitter may be used in combination with red and green pixels elements to generate different colors. By implementing deep blue emitters rather than conventional blue (e.g., cyan) emitters, the effects of cyan light on a viewer's circadian rhythm may be limited or eliminated. Moreover, by implementing deep blue emitters, the effects of cyan light on a viewer's circadian rhythm may be varied, while the colors and images are reproduced for viewing without introducing significant color distortion.
