A framework for forward-dynamics simulation of the human shoulder

Dominique Pioletti, Philippe Müllhaupt, Alexandre Terrier, Alain Farron, Ehsan Sarshari

A vast majority of the available biomechanical models of the human shoulder has been developed based on inverse dynamics, e.g. [1,2]. This imposes a number of limitations on their application. For instance, the glenohumeral joint is approximated as an idea ...

Bending Compensating Device, System and Method for Optical Waveguides

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Edgar Emilio Morales Delgado, Sebastien Walpen

A bending compensation device for a waveguide, including a direction changing device configured to maintain a constant bending angle to the waveguide, a distal end of the waveguide having a first orientation, and the proximal end of the waveguide having a ...

Method and apparatus for a photoacoustic probe using a multimode fiber

Demetri Psaltis, Christophe Moser

This invention is a method and apparatus to pick up a photoacoustic signal purely via optical means and via an endoscope. The photoacoustic endoscope invention relies only on optical excitation and detection methods. A light focus spot generates a photoaco ...

Those are Your Legs: The Effect of Visuo-Spatial Viewpoint on Visuo-Tactile Integration and Body Ownership

Olaf Blanke, Polona Pozeg

Experiencing a body part as one's own, i.e., body ownership, depends on the integration of multisensory bodily signals (including visual, tactile, and proprioceptive information) with the visual top down signals from peripersonal space. Although it has bee ...

Methods and apparatus for imaging with multimode optical fibers

Demetri Psaltis, Ioannis Papadopoulos, Christophe Moser, Salma Farahi

A multimode waveguide illuminator and imager relies on a wave front shaping system that acts to compensate for modal scrambling and light dispersion by the multimode waveguide. A first step consists of calibrating the multimode waveguide and a second step ...

Pre-Impact Fall Detection: Optimal Sensor Positioning Based on a Machine Learning Paradigm

Silvestro Micera, Fiorenzo Artoni

The aim of this study was to identify the best subset of body segments that provides for a rapid and reliable detection of the transition from steady walking to a slipping event. Fifteen healthy young subjects managed unexpected perturbations during walkin ...

Hydro-acoustic resonance behavior in presence of a precessing vortex rope: observation of a lock-in phenomenon at part load Francis turbine operation

François Avellan, Andres Müller, Christian Landry, Arthur Tristan Favrel, Keita Yamamoto

Francis turbines operating at part load condition experience the development of a cavitating helical vortex rope in the draft tube cone at the runner outlet. The precession movement of this vortex rope induces local convective pressure fluctuations and a s ...

The effect of limb crossing and limb congruency on multisensory integration in peripersonal space for the upper and lower extremities

Olaf Blanke, Joachim Jean-Marie Forget, Michiel van Elk

The present study investigated how multisensory integration in peripersonal space is modulated by limb posture (i.e. whether the limbs are crossed or uncrossed) and limb congruency (i.e. whether the observed body part matches the actual position of one's l ...

Dynamic bending compensation while focusing through a multimode fiber

Demetri Psaltis, David Ziegler, Christophe Moser, Salma Farahi

Multimode fiber endoscopes have recently been shown to provide sub-micrometer resolution, however, imaging through a multimode fiber is highly sensitive to bending. Here we describe the implementation of a coherent beacon source placed at the distal tip of ...
