Title: Leurre vibrant
Inventor: LAGUEUX ERIC
IPC: A01K85/01
Filed: 2003-06-20
Abstract: Un leurre de pêche qui a la particularité de vibrer pour simuler un insec te qui se débat à la surface de l'eau. Cette vibration attire les poissons qui se trouvent dans les environs du leurre en leur faisant croire qu'un insecte en détresse est à leur merci. La façon dont ce leurre est conçu permet l'actionnement du mécanisme de vibration tout simplement par un lancer habituel avec la canne à pêche. Il n'est pas nécessaire d'interrompre la pêche pour remonter le mécanisme. De plus, un dispositif limite le déplacement du leurre lorsqu'il est dans l'eau, ce qui permet de réactiver le mécanisme avec un rapide mouvement de la canne à pêche, comme lors de l'élan pris au moment du lancer. Cette caractéristique permet de produire des périodes de vibration supplémentaires et augmente le rayon d'action du leurre, permettant au pêcheur de profiter de l'action de vibration sur toute la distance du tir et d'augmenter le délai entre les lancers successifs.

Title: Dc/dc converter with filter for limiting the oscillation of the input current and associated method
Inventor: CINCINELLI LORENZO
IPC: H02M3/156
Filed: 2003-06-16
Abstract: The DC/DC converter with an output current which is periodically variable over time comprises a control network (11) which generates a variable reference signal (RefI) for the input current which is substantially smoothed and obtained from the difference between the output voltage (V out) and a reference voltage (V ref).  The substantially smoothed reference signal (RefI) causes a variation on the duty cycle of the converter in order to compensate for the variation in the output voltage (V out) resulting from a variation in the output current (I out).
