Title (EN) SYSTEM AND METHOD FOR DETERMINING POSITION INFORMATION VIA MODULATED VISIBLE LIGHT
(FR) SYSTÈME ET PROCÉDÉ POUR DÉTERMINER DES INFORMATIONS DE POSITION PAR L'INTERMÉDIAIRE D'UNE LUMIÈRE VISIBLE MODULÉE
Abstract: front page image
(EN)Light sources are affixed at appropriate positions in a multilevel structure or in an obstructed environment. The light sources generate modulated light signals, such as controlled light-emitting diodes, which identify the positions of the light sources by their three-dimensional global positioning coordinates and/or equivalent representation that specifies their in situ locations in the environment. Mobile communication devices, upon receiving the light signals, can derive spatial positioning information and transmit such information to a remote location, such as an emergency response system.
(FR)L'invention porte sur des sources de lumière qui sont fixées en des positions appropriées dans une structure à niveaux multiples ou dans un environnement masqué. Les sources de lumière, telles que des diodes électroluminescentes commandées, génèrent des signaux lumineux modulés, qui identifient les positions des sources de lumière par leurs coordonnées de positionnement global tridimensionnelles et/ou une représentation équivalente qui spécifie leurs localisations in situ dans l'environnement. Des dispositifs de communication mobile, lors de la réception des signaux lumineux, peuvent déduire des informations de positionnement spatial et transmettre de telles informations à un emplacement à distance, tel qu'un système de réponse aux urgences.
