The invention relates to a system for displaying dynamic and static images for advertising or informational purposes in moving vehicles, such as trains or metro. The system includes linear emitter modules installed along the windows, which synchronize video content with the movement of the vehicle and display it to passengers. These modules do not contain moving parts, ensuring high reliability and low maintenance. They use passive optical networks (PON) for synchronization and data transmission, and support dynamic content such as Full HD or 4K video. Additionally, the system provides interactive engagement through a mobile app, allowing passengers to participate in games or receive personalized content. The system ensures precise synchronization with each metro or train car, compensating for changes in speed and acceleration, providing uninterrupted viewing.

An energy harvesting system and an indicator using same are disclosed. The disclosed indicator using an energy harvester comprises: an energy harvesting unit including at least one solar cell; a panel unit, which is arranged to face the energy harvesting unit, transmits sunlight and displays guide information; and a light-emitting unit for emitting light at the side surface of the panel unit.

An augmented reality scene may be registered onto an arbitrary surface. A camera may capture an image of the arbitrary surface. The camera may analyze the surface geometry of the arbitrary surface. In some embodiments, a processing computing device may analyze data captured by the camera and an adjacent camera to reconstruct the surface geometry of the arbitrary surface. A scene may be registered to a three dimensional coordinate system corresponding to the arbitrary surface. A projector may project the scene onto the arbitrary surface according to the registration so that the scene may not display as being distorted.

A support system for an electronic display comprises one or more support frames configured to be mounted to a planar or substantially planar building structure, wherein each support frame comprises a mounting face configured for mounting one or more display modules to the one or more support frames to form a display surface, and at least one adjustment mechanism corresponding to each of the one or more support frames for adjusting a position or an alignment, or both, of the support frame relative to the planar or substantially planar building structure.

Adaptable, flexible video displays are disclosed comprised of flexible fabric or plastic panels for use as portable stadium drapes, hanging backdrops, and the like. Systems and methods for packaging or transporting rolled or folded flexible LED panels of adaptable video displays are also disclosed.

The sign incorporates a frame (1) comprising an upright (3), upper and lower structures (4, 5) that extend from the upright (1) cantilevered, between which telecommunication units are arranged, including a 5G antenna, as well as the sign incorporates a casing (2). The casing is movable with respect to the frame to facilitate the performance of maintenance operations on the telecommunication units by means of a sliding system, the upper structure (4) and the lower structure (5) incorporating for this purpose first wheels (12) intended to establish contact with internal faces of the casing (2) when it 10 moves the casing (2) with respect to the frame (1), just as the casing (2) has on two of the internal faces thereof second wheels (13) that move guided on the upper structure (4).
