Rotor Design Optimization for a Reaction Sphere Actuator

This paper presents the rotor design optimization for a reaction sphere (RS) actuator. The RS is a permanent-magnet synchronous spherical actuator whose rotor is magnetically levitated and can be accelerated about any desired axis. The RS is composed of an ...

Smart Morphable Surfaces for Aerodynamic Drag Control

Pedro Miguel Nunes Pereira de Almeida Reis

Smart Morphable Surfaces enable switchable and tunable aerodynamic drag reduction of bluff bodies. Their topography, resembling the morphology of golf balls, can be custom-generated through a wrinkling instability on a curved surface. Pneumatic actuation o ...

A computational analysis of motor synergies by dynamic response decomposition

Analyses of experimental data acquired from humans and other vertebrates have suggested that motor commands may emerge from the combination of a limited set of modules. While many studies have focused on physiological aspects of this modularity, in this pa ...

Real-time sawtooth control and NTM preemption in ITER

Olivier Sauter, Timothy Goodman, Doohyun Kim, Donghyun Kim

Real-time control of multiple plasma actuators is a requirement in advanced tokamaks; for example, for burn control, plasma current profile control and MHD stabilizationelectron cyclotron (EC) wave absorption is ideally suited especially for the latter. O ...

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 ...

Proof of principle demonstration of a self-tracking concentrator

Christophe Moser, Eric Tremblay, Volker Günter Zagolla

We present to the best of our knowledge the first successful demonstration of a planar, self-tracking solar concentrator system capable of a 2-dimensional angular acceptance of over 40 degrees. The light responsive mechanism allows for efficient waveguide ...

Model and design of dielectric elastomer minimum energy structures

Herbert Shea, Samuel Rosset, Jun Shintake

Fixing a prestretched dielectric elastomer actuator (DEA) on a flexible frame allows transformation of the intrinsic in-plane area expansion of DEAs into complex three-dimensional (3D) structures whose shape is determined by a configuration that minimizes ...

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 ...

A Double-differential Actuation for an Assistive Hip Orthosis

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier

The population ageing implies an increasing need for support especially in terms of mobility. Actuated orthoses offer new possibilities to assist walking by compensating the diminished muscular force which occurs with age. In order to assist efficiently th ...
