Abstract:
The invention is directed to a photovoltaic multilayer laminate, to a method for preparing a photovoltaic multilayer laminate, to a method for preparing a photovoltaic roadway, and to a photovoltaic roadway. The photovoltaic multilayer laminate of the invention comprises multiple flexible photovoltaic foil elements laminated at least to a carrier layer comprising electrical interconnections for said flexible photovoltaic foil elements, wherein said multiple flexible photovoltaic elements are arranged transversely to the longitudinal direction of the laminate, wherein a stretchable or compressible space is provided between each pair of multiple flexible photovoltaic foil elements.
Abstract:
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.
Abstract:
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat and that protect the support core. The support core includes a frame of longitudinal side members, end members and cross members each of which is made of steel or a thermosetting plastic material. The frame can include wood, plastic or elastomeric internal members or materials to fill internal open areas of the frame, with the upper and lower layers and the sides and ends of the frame retaining the internal members or materials therein. The mat preferably includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core to provide certified overhead lifting of the mat for installation and reclamation thereof.

Abstract:
An industrial mat that has a support core configured and arranged to support other components of the mat; and upper and lower layers that provide upper and lower surfaces of the mat, with the layers protecting the support core. Bumpers are provided upon the longitudinal sides of the core, the front and rear end sides of the core, or upon all sides to protect the core from damage due to transport or installation of the mat. The bumpers are typically made of wood, or of a plastic or elastomeric material and have a shape that absorbs impact and shock forces. The mat also includes lifting elements of D-shaped rings, O-shaped rings, chains, or cables attached to the upper or lower layer or the support core, with the lifting elements configured and dimensioned to provide certified overhead lifting of the mat for installation and reclamation thereof.
Abstract:
A recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. An energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more thermoformed energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its un-deflected configuration.
Abstract:
An interlocking floor tile assembly is provided, ft includes a first repeating array of spaced apart first tiles interconnected by first bridge portions wherein the first tiles and the first bridge portions define first spaces therebetween. It also includes a second repeating array of spaced apart second tiles interconnected by second bridge portions wherein the second tiles and the second bridge portions define second spaces therebetween. The second tiles are received in the first spaces and the first tiles are received in the second spaces. A shock attenuating tile may be provided in conjunction with the interlocking floor tile assembly to form a ground covering that is suitable for fail risk areas such as playgrounds. The shock attenuating tile preferably includes a plate having an upper side for bearing a load and a plurality of shock absorbing modules depending from an underside of the plate. Each of the shock absorbing modules is integrally formed with the plate.
Abstract:
An underlayment panel includes a top surface and a bottom surface. A plurality of projections define drainage channels. A plurality of drain holes arranged through the panel provide fluid communication between the top surface and the bottom surface.
Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.
