A streaming policy management system and method wherein bandwidth may be allocated based on external device information received from a streaming client device connected to one or more external audio/video (A/V) devices. When a streaming network back office receives a request from the streaming client device for delivery of a particular content, wherein the request includes external device information of one or more external A/V devices connected to the streaming client device, a bandwidth is determined for streaming the particular content to the streaming client device and a request may be made to a content delivery network to create a distribution pipe having the bandwidth to accommodate the delivery of the particular content. A manifest file is provided to the streaming client device that includes one or more pointers that point to content segments of the particular content.

A light suitable for lighting take-off and landing runways and taxiways of airports that includes a housing cover provided with a light passage opening, an optical system including at least one light-emitting diode module with at least one LED-chain having a plurality of light-emitting diodes as light sources, a reflector, and a prism having a shape complementary to that of the light passage opening, an insert and a sealing ring, which is arranged between the housing cover and the insert. On an underside of the housing cover of the light, the at least one LED module and reflector are arranged in a first chamber, which is separated from a second chamber of the light by a seal including a flexible insulating and heat-conducting film arranged between the reflector and the underside of the housing cover.

The invention relates to a projector (1) for light signalling, comprisinga conical mirror (16) having a truncated-cone shape (6), a plurality of laser diodes (5) emitting a light intensity towards the conical mirror (16), the inclination of the laser diodes (5) with respect to the conical surface (9) is such that the light projector (1) reflects the light intensity of the plurality of diodes (5) perpendicular to the axis (Z) of the cone, such that the conical mirror (16) reflects all of the light intensity of the plurality of laser diodes (5).

An unmanned aerial vehicle (UAV) ground station, comprising: a landing surface having a perimeter and a center; a plurality of pushers held above the landing surface by a plurality of linear actuators; at least one electro-mechanical connector attached to one of the plurality of pushers, mechanically adapted to be electrically connected to a compatible electro-mechanical connector of a UAV; and a landing detection controller adapted to instruct the plurality of linear actuators to move the plurality of pushers simultaneously from the perimeter toward the center when a landing event related to the UAV is detected.

An aerodrome system for an aerodrome is provided. The aerodrome system comprises a plurality of light emitting elements configured to emit light from a surface of the aerodrome upon which aircraft may take-off, land and manoeuvre; and a controller operatively coupled to each of the light emitting elements so as to selectively control the light emitting elements, wherein the light emitting elements form pixels of a display and the controller is configured to control an image displayed by the display so as to display and demarcate at least one runway for aircraft to take-off or land, wherein the light emitting elements are spaced such that the controller may display the runway with a variable orientation and the controller is further configured to change the image displayed by the display so as to change the orientation of the runway.

A modular landing port for use on a top of a building structure. The modular landing port includes a base portion. One or more landing module extend from the base portion. The one or more landing modules have a first end provide proximate the base portion and a second end spaced from the base portion. Each of the one or more landing modules have a landing/take-off zone proximate the second end and at least one loading/unloading zone proximate the first end. The landing/take-off zone and the at least one loading/unloading zone are configured to receive a vertical take-off and landing aircraft.

The present invention discloses a connector for an aerodrome lighting system for connecting a pair of primary cables and a pair of high voltage cables with each other among parts including a transformer, a pair of the primary cables connected to the transformer, a secondary cable for supplying electricity to a lamp, and a pair of the high voltage cables. The connector includes: a -shaped or U-shaped connector body; a receptacle formed integrally with an end portion of the connector body; and a plug formed integrally with the other end portion of the connector body, wherein the receptacle and the plug are formed integrally inside the connector and are electrically connected with each other. Two connectors are used in one aerodrome lighting system. One of the connectors connects the plug of the primary cable to the receptacle and connects the plug to the receptacle of the outgoing high voltage cable. The other connector connects the plug of the incoming high voltage cable to the receptacle and connects the plug to the receptacle of the incoming primary cable.
