ABSTRACT:
A novel small quasi-hemispherical truncated-dome modular-dot like device, which can be readily affixed to pavement in a Federally-mandated pattern via a special hole/matrix-stencil;—the resulting demarkations thereby serving to alert the Legally-blind (as well as Guide-dogs, persons in wheelchairs, and otherwise pre-occupied non-handicapped individuals) their pedestrian-pathway is entering into a potentially dangerous transition area typically crossed by a motor-vehicle pathway. The individual so called DW-DOTS™ are resilient circular low-profile devices having an annular-ramp configuration, and thus standing out only sufficiently above a foot-surface as to enable foot-tactile detection, yet not pose the potential tripping hazzard known to embedded-mats. This novel safety-button offers a desired permanent contrasting-color, plus has a definition and rugged permanency not known to poured-dot installations. The disclosure sets forth various generic-variant structural embodiments, as well as the preferred method of attachment to a walkway-pavement surface.
