Title (EN) AUTONOMOUSLY OPERATING LIGHT EMITTING DEVICES PROVIDING DETECTION AND WARNING OF HAZARDOUS CONDITION ON PATH OF TRAVEL
(FR) DISPOSITIFS ÉLECTROLUMINESCENTS FONCTIONNANT DE MANIÈRE AUTONOME PERMETTANT LA DÉTECTION ET L'AVERTISSEMENT D'UNE CONDITION DANGEREUSE SUR UN TRAJET DE DÉPLACEMENT
Abstract:
(EN) A system is disclosed comprising a plurality of light emitting devices located along a path of travel, each light emitting device comprising a light emitting source, a sensor, a communication module, and a processor, wherein when a first one of the plurality of light emitting devices is activated, the processor in the first light emitting device is configured to detect one or more physical structures surrounding the first light emitting device, detect one or more other light emitting devices, and based at least in part on the detection of the one or more physical structures and the one or more other light emitting devices, determine a location of the first light emitting device with respect to the path of travel.
(FR) L'invention concerne un système comprenant une pluralité de dispositifs électroluminescents situés le long d'un trajet de déplacement, chaque dispositif électroluminescent comprenant une source d'émission de lumière, un capteur, un module de communication et un processeur. Lorsqu'un premier dispositif électroluminescent de la pluralité de dispositifs électroluminescents est activé, le processeur dans le premier dispositif électroluminescent est configuré pour détecter une ou plusieurs structures physiques entourant le premier dispositif électroluminescent, détecter un ou plusieurs autres dispositifs électroluminescents, et sur la base, au moins en partie, de la détection de la ou des structures physiques et du ou des autres dispositifs électroluminescents, déterminer un emplacement du premier dispositif électroluminescent par rapport au trajet de déplacement.
