Aspects of the subject disclosure may include, for example, a method in which a mobile device determines a current position and direction; detects objects within an area including the current position; collects first data regarding the objects; buffers the first data; and transmits the first data to a remote system responsive to the mobile device reaching a boundary of the area. The method also comprises obtaining a map of the area from the remote device; the map includes information based on second data previously collected regarding objects in the area, the second data includes a position indicator and a direction indicator for each of the second objects indexed by the current position, and the remote device aggregates the first data and the second data to generate an updated map of the area. Navigation instructions are generated based on the current position and the map, Other embodiments are disclosed.

The problems of the prior art are addressed by a novel tactile warning system that utilizes a separate component to add photoluminescence to the tile. In certain embodiments, the tactile warning system is a replaceable tile and a cap used to cover the fastener is made using a photoluminescent material. In other embodiments, the tactile warning system is a surface applied tile, a Cast-In-Place tile or a replaceable tile, and cavities are created on the upper surface of the tile. A photoluminescent insert is then disposed in these cavities. The photoluminescent insert may be made of plastic, aluminum or acrylic.

Methods of installation, securement, removal and replacement of tactile warning surface mount plates/panels (TWSP's), preferably having at least a two color graphic design thereon, on pedestrian walkways, driveways, sidewalks, ramps, handicap ramps, retail floors and other types of existing preformed ground surfaces. The present invention includes TWSP's for both attention plates/panels and guiding plates/panels.

The invention is an assist apparatus ideally used by the visually impaired. Within a housing unit is an identifier mechanism such as a Radio Frequency Identification (RFID). The RFID generates a unique radio signal which is received by and triangulated by a group/grid of receivers within the building. The triangulation allows a computer to identify the position/location of the user for assistance or to generate a set of instructions for the visually impaired user to move to a specific location. The instructions are communicated to the user, ideally through a tactile interface, allowing the visually impaired to navigate in a strange environment.

A detectable warning system comprising a mat substrate comprising a first acrylic material and a texture layer comprising a plurality of texture elements formed from a second acrylic material disposed on a top surface of the mat substrate. The mat substrate comprises a plurality of raised portions. The first acrylic material comprises an acrylic cement and an acrylic admix. The second acrylic material comprises the acrylic cement and the acrylic admix. The second acrylic material defines a plurality of texture elements on the mat substrate.

An arcuate tactile sidewalk tile arrangement includes a connector tactile sidewalk tile including a wedge-shaped main body and one or more connector flanges that adjoin one or more longitudinal sides of the wedge-shaped main body. One or more rectilinear tactile sidewalk tiles overlap the one or more connector flanges. A plurality of truncated domes projects upwardly in a vertical direction from an upper surface of the wedge-shaped main body, as well as an upper surface of each one of the one or more rectilinear tactile sidewalk tiles.

A system and method for providing navigation information including the steps of detecting a proximate object to a referenced location, transmitting the referenced location to the proximate object, wherein the referenced location is arranged to be processed to derive a location of the proximate object, and where guidance information is available for the referenced location, transmitting the guidance information to the proximate object.

The present invention relates to tactile warning panels, and in particular to tactile warning panels that are designed and built with multifunction/multipurpose capabilities that serve the visually impaired and enable the deployment of smart city technology by integrating tactile warning systems and subsurface enclosures that can withstand pressures of five (5) tons up to and exceeding sixty (60) tons and incorporate small cells, beacons, sensors, Fog Computing, electric energy generation, rechargeable power supplies, wireless M2M communication and a plethora of other smart city technologies.

Methods, systems and devices for detectable warnings are disclosed.

A tactile plate assembly used as a tactile warning device on walkways comprises a plurality of tactile plates with texture for providing tactile awareness. A bracket connects first and second tactile plates to each other. The brackets include holes of sufficient size to allow a substrate such as concrete or asphalt to flow therethrough to anchor the tactile plate assembly in place.
