Abstract: The inventors of the present disclosure discovered that use of a urea-modified polyurethane coating as the topcoat in a pavement marking tape has numerous advantages. The urea-modified polyurethane topcoat is the reaction product of an aspartic ester polyamine, a polyisocynate, and a polyol. The urea-modified topcoat is adjacent to a base layer. The base layer and topcoat form a pavement marking tape.

IPC: G01S7/52
Abstract: A pathway article that includes a radar reflective structure with a large radar cross section (RCS) in a compact planar structure. The radar reflective structure may include a plurality of elements that act as antennae and may be spaced appropriately on a planar surface creating a radar reflecting surface. The antenna may be a reflecting surface of a stepped triangular slot. Selecting the spacing between the antennae may cause constructive interference and reflection substantially opposite the direction of the incident radar radiation. Pathway articles may also include at least one additional feature that may be detected by other sensors. Examples of other features include retroreflective features detectable by the human eye, visible camera and similar sensors. This redundancy in the detectable features of the pathway article may enable use of sensor fusion to provide greater confidence of detection of the pathway article under a wide range of conditions.

Abstract: Plurality of nanocrystalline percent by volume crystalline ceramic oxide beads, wherein the nanocrystalline ceramic oxide beads have an average crystallite size up to 250 nm, wherein each bead collectively comprises, on a theoretical oxides basis, at least one of A1 2 O 3 , SiO 2 , TiO 2 , or ZrO 2 at least 40 weight percent, and at least 1 weight percent of at least one of a transition metal oxide or at least one Bi 2 O 3 or CeO 2 , based on the total weight of the nanocrystalline ceramic oxide beads, and are visibly dark and infrared transmissive. The beads are useful, for example, in pavement markings.
