Principal axes for structural fatigue

Recent advances in the analysis of joint seakeeping processes are applied to the accumulation of spectral fatigue cycles. The methods of cross co-spectral moments and techniques adopted from the determination of principal angles for seakeeping processes ar ...

Force and torque vectors at the foot generated by surface electrical stimulation of leg muscles

Reymond Clavel, Patrick Métrailler, Carl Schmitt

MotionMakerTM is a robotic system that employs functional electrical stimulation (FES) of leg muscles to allow subjects with complete or partial paralysis of the legs to perform exercises. To achieve the greatest benefit from exercise muscles should do wor ...

Vision-based Altitude and Pitch Estimation for Ultra-light Indoor Aircraft

Dario Floreano, Jean-Christophe Zufferey, Claudio Mattiussi, Antoine Beyeler

Autonomous control of ultra-light indoor microflyers is a difficult and largely unsolved task because of the strong limitations on the kind of sensors that can be embedded. We propose a new approach for altitude control of a 10-gram microflyer, where altit ...

A new approach to accurate measurement of uniaxial joint angles based on a combination of accelerometers and gyroscopes

Kamiar Aminian, Hooman Dejnabadi

A new method of measuring joint angle using a combination of accelerometers and gyroscopes is presented. The method proposes a minimal sensor configuration with one sensor module mounted on each segment. The model is based on estimating the acceleration of ...

Orion MinAngle: A flexure-based, double-tilting parallel kinematics for ultra-high precision applications requiring high angles of rotation

Reymond Clavel, Patric Pham

If you need to design ultra-high precision devices for mechanisms with multiple axes there are not a lot of ways leading around flexure-based joints. Using this type of articulations totally eliminates backlash and friction and is, by this, providing an ac ...

Feedback and rotational stabilization of resistive wall modes in ITER

Jonathan Bryan Lister, Jean-Yves Favez

Different models have been introduced in the stability code MARS-F in order to study the damping effect on resistive wall modes (RWM) in rotating plasmas. Benchmarks of MARS-F calculations with RWM experiments on JET and DIII-D indicate that the semi-kinet ...

Hierarchical Implicit Surface Joint Limits for Human Body Tracking

Pascal Fua, Raquel Urtasun, Lorna Herda

To increase the reliability of existing human motion tracking algorithms, we propose a method for imposing limits on the underlying hierarchical joint structures in a way that is true to life. Unlike most existing approaches, we explicitly represent depend ...

Numerical simulation of deformation-induced segregation in continuous casting of steel

Michel Rappaz, Jean-Marie Drezet

The deformation-induced macrosegregation in continuous casting of steel has been simulated using a finite-volume scheme. For that purpose, a two-dimensional heat-flow computation was first performed in a Eulerian reference frame attached to the mold, assum ...

Automatic Monitoring of Bridges using Electronic Inclinometers

Olivier Burdet

The paper presents a new method for the automatic monitoring of bridges deformations. Based on the use of electronic high precision inclinometers, this method permits to accurately reconstruct the deflected shape of the bridge and to follow its long-term e ...

Drapability of dry textile fabrics for stampable thermoplastic preforms

Pierre-Etienne Bourban

Sandwiches based on stampable foam core and face sheets offer potential for cost-effective applications. Since the formability of such sandwich structures mainly depends on the drapability of the face sheets, the deformation behaviour of several types of t ...
