Quantifying the role of motor imagery in brain-machine interfaces

Hannes Bleuler, Olaf Blanke, Silvia Marchesotti, Andrea Serino, Michela Bassolino

Despite technical advances in brain machine interfaces (BMI), for as-yet unknown reasons the ability to control a BMI remains limited to a subset of users. We investigate whether individual differences in BMI control based on motor imagery (MI) are related ...

In a demanding task, three-handed manipulation is preferred to two-handed manipulation

Hannes Bleuler, Mohamed Bouri, Etienne Burdet, Elahe Abdi

Equipped with a third hand under their direct control, surgeons may be able to perform certain surgical interventions alone; this would reduce the need for a human assistant and related coordination difficulties. However, does human performance improve wit ...

A 24 mm diameter fibre positioner for spectroscopic surveys

Hannes Bleuler, Mohamed Bouri, Luzius Gregor Kronig, Philipp Hörler, Jean-Paul Richard Kneib

One of the big research topics in modern cosmology is the mystery of dark Energy. To unveil the secret, cosmologists want to measure precisely the evolution of large scale structures in the universe. One way of doing so is to measure the 3D location of a h ...

Series Elastic Actuation for Assistive Orthotic Devices: Case Study of Pneumatic Actuator

Hannes Bleuler, Mohamed Bouri, Amalric Louis Ortlieb, Jonathan Olivier

Wearable assistive robotics is a modern field where intelligent actuated systems work in collaboration with the body to replace a lost limb, to enhance performances (e.g. carrying load, walking, running, jumping) or to train or rehabilitate specific activi ...

An 8-mm diameter fibre robot positioner for massive spectroscopy surveys

Hannes Bleuler, Denis Gillet, Mohamed Bouri, Laurent Frédéric Jenni, Laleh Makarem, Jean-Paul Richard Kneib

Massive spectroscopic survey are becoming trendy in astrophysics and cosmology, as they can address new fundamental knowledge such as understanding the formation of the Milky Way and probing the nature of the mysterious dark energy. To enable massive spect ...

A flexible multimodal tactile display for delivering shape and material information

Hannes Bleuler, Simon Gallo

The growing complexity of telemanipulation tasks calls for increased realism and intuitiveness of the interaction between the user and the master control. Humans perceive multiple haptic features of an object such as its stiffness, temperature, and shape, ...

A Novel Flexible PCB Conductive Structure for Electrodynamic Bearings and Measurement in its Induced Voltage

Hannes Bleuler, Guoping Ding

This paper proposes the concept of FlexPCB(flexible Printed Circuit Board) conductive structure for electrodynamic bearings. It has three main advantages: easy "printing" of considerably thin conductive wires, resulting in potential reduction in stray eddy ...

Neurological and Robot-Controlled Induction of an Apparition

Hannes Bleuler, Bruno Herbelin, Olaf Blanke, Lukas Heydrich, Masayuki Hara, Giulio Rognini, Polona Pozeg, Roy Salomon, Andrea Serino

Tales of ghosts, wraiths, and other apparitions have been reported in virtually all cultures. The strange sensation that somebody is nearby when no one is actually present and cannot be seen (feeling of a presence, FOP) is a fascinating feat of the human m ...

The LegoPress: A Rehabilitation, Performance Assessment and Training Device

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier, Maxime Olivier Jeanneret-Grosjean

In this paper we present the LegoPress, a simple and cost-effective robotic device intended to be used for leg-press movements in rehabilitation and training. Basic adjustments can be done on the sitting position so as to maximize comfort and adapt the pos ...

A Ball-Screw Driven Motorized Hip Orthosis

Hannes Bleuler, Reymond Clavel, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb

In this paper we present a motorized hip orthosis to assist elderly people while walking, stair climbing and during the sit-to-stand transitions. The design is based on biomechanics considerations. Ranges of motion, velocities and torques of the hip joint ...

Characterization of Surface Cracks Through The Local Magnetic Field Induced by Eddy Currents

Roland Moser, Hannes Bleuler, Marco Picasso, Pavel Kejik, Gilles Raphaël Santi, David Florian Hippert

It is important to reliably characterize cracks in metallic mechanical parts in order to assess the serenity of damage due to fatigue. The most important parameter for this is the crack depth. This is notoriously difficult with standard Eddy current techni ...

Collision avoidance in next-generation fiber positioner robotic systems for large survey spectrographs

Hannes Bleuler, Denis Gillet, Mohamed Bouri, Laurent Frédéric Jenni, Laleh Makarem, Jean-Paul Richard Kneib

Some of the next generation massive spectroscopic survey projects, plan to use thousands of fiber positioner robots packed at a focal plane to quickly move in parallel the fiber-ends from the previous to the next target points. The most direct trajectories ...

Design and Control of a novel Thermo-tactile Multimodal Display

Hannes Bleuler, Simon Gallo

This paper describes the design and control of a water-based multimodal haptic display. The system is able to provide temperature and pressure (pulse) cues through a finger-sized display. Temperature feedback is obtained by mixing hot and cold water stored ...

The High-Resolution Magnetic Camera: A Novel Sensor for Eddy Current Testing

Roland Moser, Hannes Bleuler, Marco Picasso, Pavel Kejik, Gilles Raphaël Santi, David Florian Hippert

Eddy current techniques are often used to detect and, in some advanced applications, to characterize fatigue surface-breaking cracks appearing in mechanical parts. One of the major difficulties in this approach is to reliably separate the crack contributio ...

Mechanisms for actuated assistive hip orthoses

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb

Mobility is often a central problem for people having muscle weaknesses. The need for new devices to assist walking and walk related activities is therefore growing. Lower limb actuated orthoses have already proven their positive impact with paraplegic pat ...

Expanding the primate body schema in sensorimotor cortex by virtual touches of an avatar

Hannes Bleuler, Solaiman Shokur, Miguel Nicolelis

The brain representation of the body, called the body schema, is susceptible to plasticity. For instance, subjects experiencing a rubber hand illusion develop a sense of ownership of a mannequin hand when they view it being touched while tactile stimuli ar ...
