Abstract

La présente invention concerne un système de transmission de signaux (10) qui peut recevoir un signal d'entrée non électrique tel qu'un choc mécanique, une détonation, ou un signal pyrotechnique sur un terminal d'entrée (12), convertir ledit signal en un signal électrique et acheminer ledit signal électrique vers au moins un terminal de sortie (16a, 16b) situé à un emplacement distant où le signal est converti en une sortie non électrique. Afin de convertir le signal d'entrée non électrique en un signal électrique, le terminal d'entrée (12) comprend un transducteur de réception, par exemple, un élément piézo-électrique, électrochimique, ou photovoltaïque. Le terminal d'entrée (12) est connecté par câblage de transfert (14) (par exemple, à l'aide d'un faisceau électrique ou d'un câble flexible) à l'emplacement distant, où il est reçu par le ou les terminaux de sortie (16a, 16b) au niveau duquel/desquels il est converti en un signal non électrique qui est utilisé pour une fonction souhaitée. La longueur du câblage de transfert (14), et par conséquent la distance entre le terminal d'entrée (12) et l'emplacement distant, peut être comprise entre moins d'un pouce et supérieure à 100 pieds. Eventuellement, le câblage de transfert (14) peut relier le terminal d'entrée (12) à une pluralité de terminaux de sortie (16a, 16b). Un terminal de sortie peut en outre éventuellement comprendre un élément de pontage explosif (pont semi-conducteur, inflammateur, feuille explosive) qui peut être amorcé par le signal électrique et l'élément de pontage peut amorcer une charge de sortie brisante (explosive ou pyrotechnique). Dans une variante, le terminal de sortie peut comprendre un transducteur de sortie, par exemple, un transducteur piézo-électrique, destiné à convertir le signal électrique en une impulsion physique.
