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.

Methods of forming ceramic matrix composite structures include joining at least two lamina together to form a flexible ceramic matrix composite structure. Ceramic matrix composite structures include at least one region of reduced inter-laminar bonding at a selected location between lamina thereof. Thermal protection systems include at least one seal comprising a ceramic matrix composite material and have at least one region of reduced inter-laminar bonding at a selected location between lamina used to form the seal. Methods of forming thermal protection systems include providing one or more such seals between adjacent panels of a thermal protection system.

The present invention involves a cover for a spraying device of a robot which is formed from a polymer with enhanced residue retention properties. The polymer may be processed to increase the surface energy of the polymer. For example, the polymer may be subjected to a corona treatment in order to increase its surface energy. The corona treatment process may be performed on the polymer as received, prior to cutting or otherwise manipulating the polymer. Also, the polymer may be embossed to provide the enhancement. To assemble the polymer into a robot cover, the polymer as received may be cut into individual sections for assembly. The sections may then be assembled to one another by heat sealing the sections together. The heat sealing provides a bond between the individual sections of polymer that secures the individual sections together to create the robot cover. The polymer may also be formed into tubular sections for securing to the spraying device.

Example implementations of a synthetic turf system comprise a turf tray and a turf element. The turf tray is rigid and planar, and has a lattice structure extending within the lateral perimeter. The turf element includes a backing portion and a blade portion. The blade portion is defined by a plurality of blades of artificial grass affixed to the backing portion, the backing portion is placed secured engagement with the upper side by way of, for example, adhesive or screws. The turf trays may include perimeter and auxiliary adhesive tracks, and an array of screw retention bosses. The system may include a sprinkler assembly mountable in the turf trays for washing down the turf elements. The sprinkler assembly may include mounting flanges configurable to accommodate mounting of various sprinklers. The system may include height-adjustable pedestals or joists to support the turf trays at a distance above the local horizonal surface.
