摘要： A dynamic paver device with vibration feedback is provided. In some embodiments, a paver device comprises: a paver having a top surface and a bottom surface; a paver frame that creates an interior cavity upon being connected with the paver; at least one pressure sensor connected to the paver, wherein the at least one pressure sensor detects a change in an amount of pressure applied to the top surface of the paver; a vibration system connected to the bottom surface of the paver, wherein the vibration system is configured to provide a vibrational force to the bottom surface of the paver; and a controller connected to the at least one pressure sensor and the vibration system, wherein the controller is configured to: receive, from the at least one pressure sensor, a presence indication of an object on the top surface of the paver based on the detected change in the amount of pressure being applied to the top surface of the paver at a first time; and, in response to receiving the presence indication from the at least one pressure sensor, transmit a first signal to the vibration system that causes the vibration system to provide the vibrational force to the bottom surface of the paver.

摘要： Detectable warning areas (DWAs) and methods of forming the same. A dome-forming material can be mixed with a catalyst to form a mixture, which can then be poured into a dome-shaped cavity of a die-cast mold or a reusable mat template with a grommet. A peg may be inserted into the mixture. The mixture may be allowed catalyze and harden.

摘要： A tactile tile assembly includes a base having a plate section, a rim projecting up from the plate section, and a plurality of embedment anchors on the base. A tactile tile is adapted to fit into or onto the base. Fasteners extending through the tactile tile attach it to the base. The top of the rim may be substantially co-planar with a top surface projections on the tactile tile. The embedment anchors may be provided in a plane of the plate section and be bent to a position perpendicular to the plate section for embedment into a pavement material. The base has attachment elements for attaching the tile assembly to an adjoining tile assembly. Two or more tile assemblies are attached together to provide a tile assembly combination of a desired size and shape. The tile assembly combination is then installed in the paving material.

摘要： A dual-unit paving system for covering a surface has pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are configured to be matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly allows forming rotational tessellations. The first and second units are also shaped and configured to be matingly engageable so as to form horizontally aligned tessellations, and also vertically aligned tessellations.

摘要： An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.
