Pivot, process for manufacturing such a pivot, oscillator comprising such a pivot, watch movement and timepiece comprising such an oscillator
Simon Nessim Henein, Loïc Benoît Tissot-Daguette
The present invention concerns a pivot comprising two assemblies, namely a central assembly (401) and a peripheral assembly (400). These two assemblies are mobile in rotation relative to each other around an axis of rotation (A). The pivot is characterized ...
2024Experimental observation of topological transition in linear and nonlinear parametric oscillators
Romain Christophe Rémy Fleury, Benjamin Apffel
Parametric oscillators are examples of externally driven systems that can exhibit two stable states with opposite phase depending on the initial conditions. In this work, we propose to study what happens when the external forcing is perturbed by a continuo ...
2024Super-harmonically resonant swirling waves in longitudinally forced circular cylinders
François Gallaire, Alessandro Bongarzone, Alice Evelyne Julienne Marcotte
Resonant sloshing in circular cylinders was studied by Faltinsen et al. (J. Fluid Mech., vol. 804, 2016, pp. 608-645), whose theory was used to describe steady-state resonant waves due to a time-harmonic container's elliptic orbits. In the limit of longitu ...

Neuromorphic computing is a wide research field aimed to the realization of brain-inspired
hardware, apt to tackle computation of unstructured data more efficiently than currently done
with standard computational units. Oscillatory neural networks are know ...
EPFL2021Mechanical oscillator with tunable isochronism defect
Simon Nessim Henein, Mohammad Hussein Kahrobaiyan, Mohamed Gamal Abdelrahman Ahmed Zanaty
Mechanical oscillator (1) for a timepiece comprising an inertial mass (3) arranged to oscillate about a neutral position under the effect of a restoring force provided by at least one elastic element (5),characterised in that said mechanical oscillator (1) ...
2020Statically and dynamically balanced oscillator based on Watt's linkage
Simon Nessim Henein, Hubert Pierre-Marie Benoît Schneegans, Ilan Vardi
We present a new mechanical oscillator architecture that can be made insensitive to linear and angular accelerations while keeping constant oscillation frequency. The oscillator has the kinematics of a Watt linkage, so we call it a Watt oscillator. In orde ...
EUSPEN2020Evidence of Smaller 1/F Noise in AlScN-Based Oscillators Compared to AlN-Based Oscillators
Luis Guillermo Villanueva Torrijo, Marco Liffredo, Andrea Lozzi
In this paper we investigate the direct effect of resonator quality factor (Q) on the oscillator phase noise. We use 2-port contour mode resonators (CMRs), fabricated both with aluminum nitride (AlN) and aluminum scandium nitride (AlScN), as the frequency- ...

Simon Nessim Henein, Billy Nussbaumer
Crank arrangement (1) for driving a pin-driven two degrees? of freedom mechanical oscillator (5), comprising:- a crank element (7) arranged to be rotationally driven about an axis of rotation (19) by means of a mechanical source of energy (M),- a crank slo ...
2020Time-Delay Encoded Image Recognition in a Network of Resistively Coupled VO2 on Si Oscillators
Kirsten Emilie Moselund, Siegfried Karg
Oscillatory neural networks based on insulator to metal transition of VO2 switches are implemented for image recognition. The VO2 oscillators are fabricated on silicon in a CMOS compatible process.A fullyconnected network of coupled oscillators is investig ...
2020Activity induced synchronization: Mutual flocking and chiral self-sorting
Synchronization, the temporal coordination of coupled oscillators, allows fireflies to flash in unison, neurons to fire collectively, and human crowds to fall in step on the London millenium bridge. Here, we interpret active (or self-propelled) chiral micr ...
