Abstract:
L'invention concerne un tapis (10) enroulable sur lui-même ayant une direction longitudinale (L) et une direction transversale (T), le tapis comportant au moins une première (20) et une deuxième (20') poches s'étendant selon la direction transversale du tapis, chacune des première et deuxième poches étant définie entre au moins une première portion (22, 22'), et une seconde portion (28, 28') fixée à la première portion. L'invention se caractérise par le fait que la première portion de chaque poche présente un bord latéral d'extrémité libre (26, 24') disposé en regard de l'autre poche et s'étendant selon la direction transversale du tapis, le bord latéral d'extrémité libre (26) de la première portion (22) de la première poche (20) étant distant et distinct du bord latéral d'extrémité libre (24') de la première portion (22') de la deuxième poche (20').
Abstract:
A support surface (112) configured to be electrically connected to at least one other support surface and deployed on or near the earth's surface includes a mat (26) having top and bottom surfaces. An electrically-conductive cover (110) extends at least partially across the top surface of the mat. At least one electrically-conductive interface (138) is associated with the electrically-conductive cover. The support surface also comprises at least one electrically-conductive metallic band (188) which, in connection with the electrically-conductive interface, is configured to facilitate electrical connection of the electrically-conductive cover to at least one other support surface.
Abstract:
A pavement interlayer, suitable for laying between layers of pavement, comprising: at least one layer (200) of interlayer material, a plurality of piezoelectric elements (202); at least one transmission line (203), coupled to the plurality of piezoelectric elements (202), for transmitting power generated by the plurality of piezoelectric elements (202) to an output.
Abstract:
Some deck or patio areas constructed of pavers mounted on adjustable pedestal supports must remain snow and ice free on their top surfaces. The pedestal-mounted paver heating system is designed to allow easy installation of electric heating cable that is positioned against the bottom surface of pavers so that heat generated by the cable is efficiently transferred up into die pavers to raise their temperature enough to prevent the accumulation of snow and ice on their top surfaces.
Abstract:
A modular cell that may be used with other cells to form a matrix under a load bearing feature, the cell being a single piece moulding that supports a compressive load placed thereon, the moulding including a void space defined within: a skirt shaped support member defining a substantially planar surface with an opening therein; and at least one leg integral to and extending from the support member. The cell further includes at least one separate linking member that releasably links together multiple cells to form a matrix of cells. The cells may be linked together vertically and/or horizontally. The cell and matrix include greater load bearing capacity and rigidity through aligned legs to carry the weight as well as interlinking members that act to share the load among the various cells. The design also requires less material hence is cheaper to produce. The void space is also easily accessed hence allowing for easy access, filling and laying of utility lines where needed.
Abstract:
A modular pavement slab comprises a body, a strain sensor array, and a sensor processor. The body includes a top surface, a bottom surface, and four side surfaces. The modular pavement slab is configured to be coupled to at least one other modular pavement slab via connectors along at least one of the side surfaces. The strain sensor array is retained within the body and is configured to detect a plurality of strains on the body resulting from vehicular traffic across the top surface of the body. The sensor processor is in communication with the strain sensor array. The sensor processor is configured to communicate input signals to the strain sensor array, receive output signals from the strain sensor array, and determine a plurality of time-varying strain values, each strain value indicating a strain experienced over time by a successive one of a plurality of regions of the body.
Abstract:
A system for pavement slab analysis based on data regarding transfer of force through a sensing volume responsive to exertion of weight on the sensing volume by passing objects including a precast pavement slab defining the sensing volume and having a top surface, a plurality of strain gauges embedded in the pavement slab within the sensing volume, and load-transferring connector(s) attaching the pavement slab to an adjacent slab. The strain gauges are distributed across an XY coordinate plane parallel to the top surface. The system also includes a processing element and computer-readable instructions for receipt of electrical signals from the strain gauges and to analysis of the electrical signals to determine one or more of the following: (A) risk of a structural defect in the pavement slab, (B) risk of a problem with underlying sub-grade beneath the pavement slab, and (C) movement of the passing objects across the top surface.
