A light fixture for a public transportation train system powers an antenna used for train signaling. The antenna can provide to the train a location marker associated with the location of the antenna. The antenna can provide to the train other data communicated to the light fixture through the light fixture communication system.

A method of manufacturing an aircraft photoluminescent marker that comprises a substrate includes providing an ink or coating adapted to be cured with ultra violet (UV) radiation and printing one or more markings directly onto the substrate of the photoluminescent marker with the ink or coating, followed by curing the ink or coating with UV radiation. The substrate is one of a photoluminescent material or a housing, and the marking comprises at least one of a pattern, wording, images, blocks, or indicia.

A method of operating an aircraft cabin illumination system, having a plurality of light modules with a set spatial distribution across an aircraft cabin, includes receiving an image; mapping the image to the set spatial distribution of the plurality of light modules; generating an illumination command set, including an operating command for each of the plurality of light modules, on the basis of the mapping of the image to the set spatial distribution of the plurality of light modules; and issuing the illumination command set to the plurality of light modules.

An aircraft includes an aircraft body including one or more exterior surfaces and a projector secured to a component of the aircraft. The projector is configured to selectably project one or more images on the one or more exterior surfaces. A method of displaying a projected image on an aircraft surface includes moving a landing gear assembly of the aircraft from a retracted position to an extending position, activating a projector disposed at the landing gear assembly, and displaying a projected image at the aircraft surface via activation of the projector.

The present disclosure provides an LED straight light including a light tube with two pins at both ends, an LED installed in the light tube and a driving circuit. The driving circuit includes a mains branch and a signal branch. The mains branch is coupled to the pins at one end of the light tube for transmitting power to the LED for power supply. The signal branch is coupled to the pins at the other end of the light tube for transmitting external driving signals to control the on/off of the mains branch. The LED straight light of the present disclosure is powered by two ends, one of the two ends supplies power to the LED through the mains branch, and the other end receives driving signals to control the on/off of the mains branch.

Disclosed is a motion sickness reduction system for vehicles, the motion sickness reduction system including an interface configured to exchange a signal with at least one electronic device mounted in a vehicle, at least one light output area located around a screen of at least one display, and a processor configured to provide a control signal for changing the pattern of light output from the light output area based on information about the state of the vehicle received from the electronic device.

Disclosed is a cabin system configured to acquire first information about a first user and second information about a second user through a communication device, to specify each of the first user and the second user based on image data received from an internal camera or an external camera, to provide a control signal to a display or a speaker such that content is provided to a user based on an electrical signal generated by an input device, to determine a first boarding seat of the first user among seats according to the first information and to determine a second boarding seat of the second user among the seats according to the second information, and to determine the posture of the first boarding seat according to the first information and to determine the posture of the second boarding seat according to the second information.

A photoluminescent aircraft floor path marking system includes at least a flexible track having a housing incorporating a flexible, pliable, photoluminescent portion in which the track is bendable to a radius of 1 m or less and the track has a length of at least 2 m, where the track is pliable such that it can retain a rolled or bent radius. The track may be bendable to a radius of from 0.01 m to 1.0 m or optionally from 0.01 m to 0.5 m. The flexible track may be provided in lengths of from 3 m or greater or greater than 10 m. A flexible protective layer may be provided. The flexible housing may include a holder for the photoluminescent material.
