A method includes positioning one or more roadway sensors and a plurality of a networked array of light emitting diode (LED) raised pavement markers on a road. Sensors proximate the road are associated with a network of road marking controllers that cooperate to control the LEDs as vehicles drive on the road. The LEDs operate as a networked array of roadway lane marking lights. The road marking controller(s) determine a distance between a vehicle on the road and the roadway sensor, determine a dynamic condition associated with the vehicle that changes with respect to time, and lights the plurality of LEDs based at least in part on the distance between the vehicle and the roadway sensor and the dynamic condition associated with the vehicle. Dynamic conditions for operating the LED lighting scheme can include vehicle velocity, a date, a time, a weather condition proximate the vehicle, and other factors.

A covering element for a floor covering comprising an upper surface having a relief structure, wherein the relief structure comprises excavations having a depth decreasing towards at least one perimetric edge of the covering element.

A deck assembly includes a deck panel having a plate shape extending in a first direction and having a clip insertion groove recessed from each of both side surfaces thereof, a lower support disposed below the deck panel in a second direction that is perpendicular to the first direction, and a quick clip module coupled to one side surface of the lower support to fix the deck panel in a separable manner.

The invention relates to a paving composed of a plurality of individual paving stones with irregularly curved lateral faces. The individual paving stones have, on their irregularly curved lateral faces, chains or partial chains of adjoining, spaced apart strip-shaped connection sections that mesh together in the manner of a gear rack with connection sections of adjoining paving stones. This makes it possible to achieve paving connections even with randomly shaped paving stones.

The invention relates to a paving stone (1) and to a paving produced using same. A strip-shaped connection section (4) is provided at least on one lateral face of the paving stone, which vertically projects from same and interacts with strip-shaped connection sections of adjoining stones in the course of producing a paving and establishing a connection. The connection section (4) has a stepped shape with at least three graduated shoulders one over another. This both achieves a joint that expands in the upward direction, and prevents the pointing from loosening or being cast upward when forces act upon the paving, for example when subject to vibrations.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.
