Abstract: A dynamic tracking system comprises a three-dimensional camera based on time-of-flight technology, which comprises a receiver sensitive to the light emissions comprised in a certain range of wavelengths, a first emitter of light signals, a micro-computer interfacing and computing three-dimensional information coming from the receiver and controlling the emitter, and an internal or external secondary computer incorporating data analysis, database services, controls and external interfacing to vehicle and local or global data communication services.

Abstract: A light source for illuminating a selected surface, the light source comprising a plurality of Light Emitting Diodes (LED) mounted on a substrate; each of the plurality of LEDs having an optical axis and generating a radiation pattern propagating along the optical axis. The plurality of LEDs are arranged so that each optical axis is oriented substantially towards a determined far-field central point; and the plurality of LEDs provide a predetermined irradiance distribution on the selected surface. Each of the radiation patterns defines a preferential direction; and each of the plurality of LEDs is arranged so that the preferential direction of each of the plurality of LEDs is unique.
