The active signal marker aiding in the landing of vehicles during varying environmental conditions.

A method and device for easily installing and removing an airport light on a runway using a fixture ring having a base ring; an annular lip operatively connected to and extending radially inwardly from the base ring; a lift bar operatively connected to the annular lip and extending from one side to the diametrically opposite side of the annular lip; and an extractor, operatively connecting the lift bar to the annular lip to cause the lift bar to move up and down relative to the annular lip.

A ground level illumination system such as a road stud comprises a light source (12) positioned below ground level (8). An optics block (9) and a top block (2) transmit light from the source (12) to the exterior, the light rising at a shallow angle as a collimated beam in the top block (2) to emerge at a window (4) above the ground level (8). The window (4) is shaped to refract the light into a beam (16) that descends at a shallow angle relative to the ground level (8). The emerging beam (16) may be used to illuminate road markings (26) formed from luminous paint that can be re-charged by the illumination system. A feedback mechanism (82) can measure reflected light levels to maintain the optimal charge in the paint. A further element (84) of the system may also compare the intensity of reflected light at different wavelengths to detect the presence of fog.

A method and device for easily installing and removing an airport light on a runway using a fixture ring having a base ring; an annular lip operatively connected to and extending radially inwardly from the base ring; a lift bar operatively connected to the annular lip and extending from one side to the diametrically opposite side of the annular lip; and a pair of extractors, operatively connecting the lift bar to the annular lip to cause the lift bar to move up and down relative to the annular lip.

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.
