Haptics based collaborative steering control in automated driving environments

Tomohiro Nakade

A vehicle's steering is a particular system in that it is exposed to individual subjective reviews based on criteria that are hard to assess quantitatively. Haptic design of such systems is a prime concern that has been at the center of industrial developm ...

PopTouch: A Submillimeter Thick Dynamically Reconfigured Haptic Interface with Pressable Buttons

Herbert Shea, Amir Firouzeh, Ayana Mizutani

The interactions with touchscreens rely heavily on vision: The virtual buttons and virtual sliders on a touchscreen provide no mechanical sense of the object they seek to represent. This work presents PopTouch: a 500 mu m thick flexible haptic display that ...

Interspace and Vacancy Modulation: Promoting the Zinc Storage of an Alcohol-Based Organic-Inorganic Cathode in a Water-Organic Electrolyte

Kangning Zhao, Yutao Li

Expanding interspace and introducing vacancies are desired to promote the mobility of Zn ions and unlock the inactive sites of layered cathodes. However, this two-point modulation has not yet been achieved simultaneously in vanadium phosphate. Here, a stra ...

Motor-wheel for an omni-directional mechanism and vehicle using the same

Mohsen Falahi

The present invention relates to a motor-wheel for an omni-directional motion vehicle, comprising a ring-shaped structure with a central axis, presenting an outer radial surface and an inner radial surface, whereby the outer radial surface comprises a plur ...

Motion planning for CAVs in mixed traffic, a study on roundabouts

Ezequiel González Debada

Driving is a very challenging task to automatize despite how naturally and efficiently it may come to experienced human drivers. The complexity stems from the need to (i) understand the surrounding context and forecast how it is likely to evolve, (ii) plan ...

Implantable fluid delivery device

Nikolaos Stergiopoulos, Michel Bachmann

An implantable delivery device for delivering a fluid in a controlled manner, including a body having a chamber, a tube having an inlet and an outlet, at least a portion of the tube passing through the chamber, a drive pinion operatively connected to a mot ...

Interactive optimization for supporting multicriteria decisions in urban and energy system planning

Sébastien Cajot

Climate change and growing urban populations are increasingly putting pressure on cities to reduce their carbon emissions and transition towards efficient and renewable energy systems. This challenges in particular urban planners, who are expected to integ ...

Detecting EEG correlates during preparation of complex driving maneuvers

Lucian Andrei Gheorghe

The main focus of this research is the development of real-time recording and analysis devices and algorithms for detecting Electroencephalography (EEG) correlates of steering actions. First, offline analysis where performed in a high fidelity driving simu ...

A Friction Compensation Control for Power Steering

Philippe Müllhaupt, Robert Fuchs

The effects of friction are critical to the dynamics of electric power steering (EPS). On the one hand, friction contributes to the stability of the system and filters some of the disturbances (road vibration, etc.). On the other hand, it affects negativel ...

Cheetah-cub-S: Steering of a Quadruped Robot using Trunk Motion

Auke Ijspeert, Peter Eckert

A reliable concept for steering was realized by in- tegrating a spine-like structure with one DoF into a quadruped robot - Cheetah-cub-S. We increased maneuverability dramat- ically compared to a robot with rigid spine, while keeping controlling effort low ...

Steerable PCA for Rotation-Invariant Image Recognition

Michaël Unser, Cédric René Jean Vonesch

In this paper, we propose a continuous-domain version of principal-component analysis, with the constraint that the underlying family of templates appears at arbitrary orientations. We show that the corresponding principal components are steerable. Our met ...

Preliminary design of the ITER ECH Upper Launcher

Olivier Sauter, Timothy Goodman, René Chavan, Jean-Daniel Landis, Francisco Sanchez

The design of the ITER electron cyclotron launchers recently reached the preliminary design level - the last major milestone before design finalization. The ITER ECH system contains 24 installed gyrotrons providing a maximum ECH injected power of 20 MW thr ...

Quotient method for stabilising a ball-on-a-wheel system – Experimental results

Dominique Bonvin, Philippe Müllhaupt

This paper extends the quotient method proposed in [1] and applies it to stabilize a “ball-on-a-wheel” system. The quotient method requires a diffeomorphism to obtain the normal form of the input vector field and uses canonical pro- jection to obtain the q ...

Progress on the ITER H&D EC Upper Launcher Steering-Mirror Control System

Timothy Goodman, René Chavan, Federico Alberto Alfredo Felici, Francisco Sanchez, Robert Bertizzolo, Jean-Daniel Landis, Frédéric Dolizy

The ITER Heating and Current Drive Upper Launcher (H&CD EC UL) uses a pneumomechanical steering-mirror assembly (SMA) to steer the RF beams for their deposition in the appropriate location in the plasma to control magnetohydrodynamic activity (neoclassical ...

Wavelet Steerability and the Higher-Order Riesz Transform

Michaël Unser, Dimitri Nestor Alice Van De Ville

Our main goal in this paper is to set the foundations of a general continuous-domain framework for designing steerable, reversible signal transformations (a.k.a. frames) in multiple dimensions (d ≥ 2). To that end, we introduce a self-reversible, Nth-order ...

Progress On The Iter Upper Launcher Millimeter Wave Design And Testing

René Chavan, Federico Alberto Alfredo Felici, Frédéric Dolizy

The main purpose of the ITER ECH upper launcher is to control magnetohydrodynamic activity, in particular neoclassical tearing modes, in the plasma. The mm-wave optical system is optimized to insure that the eight RF beams are all focused to a small beam w ...
