Apparatus and method for providing improved detection and identification of objects (e.g. people, pets, bicycles or vehicles), by devices, such as autonomous vehicles, that rely on non-visible detection systems, such as lidar, for understanding their surrounding environment. Such objects having integrated or embedded materials of a predetermined shape or pattern that is readily detectable and identified by devices using such detection systems, such as autonomous vehicles. The predetermined shape or pattern is of a material, such as aluminum, that is more easily detectable by a non-visible detection system and allows the detection system to recognize and identify the type of object, even in challenging visibility conditions.

The visible safety bicycle is a system of several photo-luminescent plastic spirals to be visible day and night alternately, which will surround each part of the bicycle; bicycle frame parts, bicycle handlebar, bicycle seat post, bicycle fork, bicycle wheel hub, and also bicycle wheel's spokes, with high visibility of the area where they are installed, achieving security for the user.

This invention is a commercially manufactured article of manufacture (such as a shoulder patch) comprising an infrared (IR) phosphorescent material that emits in the IR wavelength range (e.g., from approximately seven-hundred nanometers (˜700 nm) to approximately one millimeter (˜1 mm)) after being excited by incident wavelengths of between ˜100 nm and ˜750 nm (or visible light). In other words, once the material has been exposed to visible light, the material will continue to emit in the IR wavelength range for a period of time, even when the material is no longer exposed to the visible light.

A hem cover for use with a trouser leg constructed from at least one material having an interior side and an exterior side. The hem cover has an outwardly facing side opposite an inwardly facing side. The hem cover is positionable along an edge of the trouser leg and foldable to position a first portion of the inwardly facing side along the interior side and a second portion of the inwardly facing side along the exterior side of the at least one material. The inwardly facing side includes an adhesive layer configured to temporarily adhere to the first and second portions to the interior and exterior sides, respectively, to thereby cover a covered portion of the edge of the trouser leg.
