A la recherche du temps précis : la découverte de l’oscillateur

Simon Nessim Henein, Ilan Vardi

L'introduction d'un oscillateur comme base de temps a marqué une révolution dans la mesure précise du temps. Cet article décrit comment les chercheurs du 17e siècle ont découvert les oscillateurs qui règlent nos horloges et montres mécaniques. Une lecture ...

Programmable Multistable Mechanisms for Safe Surgical Puncturing

Simon Nessim Henein, Charles Baur, Andrea Lovera, Ilan Vardi, Mohamed Gamal Abdelrahman Ahmed Zanaty, David Lambelet, Thomas Jean Julien Fussinger, Arno Rogg

We present novel medical devices for safe surgical puncturing, in particular a cannula for the treatment of retinal vein occlusion (RVO). This passive mechanical device has an adjustable stroke and exerts a puncturing force independent of operator applied ...
