Systems and methods for a permeable pavement system are described. The permeable pavement system includes blocks designed to facilitate water seepage between the blocks and to permit water storage within the blocks. The blocks may be cabled together to create paving units that facilitate installation and maintenance of the pavement system. The permeable pavement system may also be heated to a predetermined range with either electrical energy or hydronic heating.

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.

A method and a court for playing a sporting match are provided. The court includes a springboard floor in a generally rectangular shape. A wall surrounds the floor and has a lower portion of padded material and an upper portion of transparent material. Sidelines and baselines are disposed around the periphery of the floor. Tackle zones is disposed between the base lines and the sidelines. An o-zone is in the center of the floor. A pair of goals are on opposing sides of the court, each goal comprising a backboard, central hoop, and two backboard goals defined by the backboard. Aa pair of goalie boxes are disposed on opposing sides of the court under each of the goals. Pairs of three-, four-, and five-point lines disposed on opposite sides of the floor. Penalty boxes disposed in the wall.

Described herein is a modular skate system that includes at least one modular skate component comprising a major surface, a core comprising a body formed from a first material, an outer layer formed from a second material, the outer layer surrounding at least a portion of the core, wherein the first material is different from the second material, and wherein the major surface comprises the outer layer.

There exists a number of youth development programs centered on sports programming. Some of these programs operate on a platform of revitalizing neighborhood spaces to improve community engagement by creating a space for youth to enjoy sports. Oftentimes these neighborhood spaces include restrictions or the surrounding community has needs (like lighting and seating) which are unmet or under-met. Envisioned is a system approach to addressing these needs wherein a wide variety of custom solutions can be produced from prefabricated, modular, and portable components that interface with existing amenities (if any) so to enrich the youth experience and better achieve program objectives. This modular approach provides a common infrastructure for different spaces, different sports, and different levels of play.

According to a resilient platform assembly, a playing deck includes a plurality of horizontally disposed deck panels. Each deck panel of the plurality of horizontally disposed deck panels has a pair of foot flanges on the bottom of the deck panels. Receiving shoes are attached to the deck panels. The receiving shoes are configured to receive the foot flanges of the deck panels. A transverse member is perpendicular to the plurality of horizontally disposed deck panels. The transverse member includes a plurality of notches. Each notch of the plurality of notches is cut in the transverse member in a predetermined spacing pattern. The receiving shoes are installed in the notches and the deck panels are attached to the transverse member through the receiving shoes. Resilient mounts connect the transverse member to a support assembly and allow relative motion between the transverse member and the support assembly.

A modular ramp system includes a ramp component and a connector releasably joined to the ramp component. The ramp component has first and second inclined surfaces and a connecting portion positioned between the first and second inclined surfaces. The connector has a bottom side formed with a first and second coupling section connectable to the connecting portion. The connector is positionable in a first position in which one of the first and second coupling sections is releasably joined to the connecting portion of the ramp component and the other of the first and second coupling sections is adapted to releasably couple to a ramp or an external structure, and a second position in which the first and second coupling sections are releasably joined to connecting portion of the ramp component.

Problem: To provide a technique suitable for the circular economy that allows reduction of the environmental load.

Solution: A soil paving material for paving soil on topsoil includes a stone dust 110, a baked rice bran 120, and a solidifying material 130. The stone dust 110 is produced when a stone material is processed. The baked rice bran 120 is produced by baking rice bran into a carbonized state. The solidifying material 130 used for the soil paving material includes at least one of a calcined plaster and a hydrated lime.

An equestrian arena surface filtration system includes a plurality of wash drains configured to be buried below an arena surface and each wash drain having a coupling. The system also includes a wash pipe coupled to the plurality of wash drains via a respective coupling and a plurality of wash boxes. Each of the wash boxes has a stub pipe passing therethrough and the stub pipe has an upper end and a lower end. The lower end of the stub pipe is configured to be coupled to the respective coupling. In addition, the tops of the plurality of wash boxes are adjusted to be positioned approximately at a same level as a top of the arena surface so that wash water flooding the arena surface is collected by the plurality of wash boxes and flushed out through the wash pipe.
