Abstract

L’invention concerne un procédé et un dispositif pour convertir en énergie électrique des oscillations mécaniques d’objets en mouvement. Ledit procédé comprend une excitation, une capture, une fixation et une accumulation desdites oscillations mécaniques dans la zone de mouvement desdits objets en mouvement en réponse à des perturbations aléatoires causées par le mouvement desdits objets avec des valeurs aléatoires de masse, de caractéristiques dynamiques et d’intensité de flux, et une conversion desdites oscillations mécaniques en un mouvement rotatif de l’arbre d’un mécanisme actionneur situé en dehors de la zone de mouvement desdits objets en mouvement et perpendiculairement à la direction de leur mouvement. L’utilisation maximale possible de l’énergie potentielle et cinétique de véhicules en mouvement et l’accumulation d’énergie par des ressorts et la transmission de cette énergie au mécanisme la convertissant en énergie électrique au moyen d’un encliquetage spécial à double rochet permet de réaliser un dispositif qui utilise le plus efficacement les oscillations provenant de divers objets en mouvement.
