Patent ID: 7943213

Claim:
An artificial surface, comprising in combination: first layer including a top surface comprising an artificial turf sheet and a permeable layer below the artificial turf sheet that absorbs and drains water from the artificial surface; and a second layer in contact the first layer including a plurality of separate compartments including a plurality of microbeads of pre-selected sizes and shapes, wherein an initial contour of the artificial surface is formed by an interaction of the artificial turf sheet and mircobeads in the plurality of separate compartments of the pre-selected sizes and shapes filled to pre-selected depths, wherein interactions of the surfaces of microbeads of the pre-selected sizes and shapes and depths provide a plurality of different types of resistance and firmness for the artificial surface, and wherein the artificial surface does not require the application of a vacuum to maintain a shape or resistance; and the plurality of microbeads including a pre-determined compound applied to surfaces of the plurality of microbeads to produce an electrical charge on the surfaces thereof, wherein the electrical charge provides different resistance and firmness properties of the artificial surface compared to an artificial surface comprising a plurality of microbeads without the pre-determined compound applied.
