DextrES: Wearable Haptic Feedback for Grasping in VR via a Thin Form-Factor Electrostatic Brake

Herbert Shea, Ronan Julien Hinchet

We introduce DextrES, a flexible and wearable haptic glove which integrates both kinesthetic and cutaneous feedback in a thin and light form factor (weight is less than 8g). Our approach is based on an electrostatic clutch generating up to 20 N of holding ...

Different approaches to improve energy consumption of battery electric buses

Francesco Baldi

Transportation electrification is increasing and recently more focus has been directed on heavy vehicles and especially on city buses. Battery electric buses are inherently more energy efficient than diesel buses and the efficiency can be further increased ...

Updated braking forces for the assessment of road bridges

João Miguel De Oliveira Durães Alves Martins

Safety assessments of road bridges to braking events combine the braking force, acting along the longitudinal axis of the deck, with a vertical load that accounts for the vertical component of the traffic action. In modern design standards the vertical loa ...

Deriving a load model for the braking force on road bridges: Comparison between a deterministic and a probabilistic approach

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart, Glauco Feltrin

The current provisions for the braking force in the Eurocodes are much more demanding than previously enforced national codes from most European countries. Hence, safety assessments of existing bridges may show a lack of compliance with the new safety requ ...

Defining a braking probability to estimate extreme braking forces on road bridges

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart, Glauco Feltrin

A probabilistic approach is necessary to estimate the magnitude of the braking force that compares in terms of return period with the vertical traffic loads present in bridge design codes. A data set from a Danish Field Operational Test served as support t ...

Design and Control of a Modular Multilevel DC/DC Converter for Regenerative Applications

Alfred Rufer, Daniel Montesinos Miracle

This paper compares different cascaded and multilevel topologies to interface supercapacitors to a dc bus in regenerative braking applications. It is shown that the modular multilevel dc/dc converter (MMC) can benefit from both reduced voltage and increase ...

A Haptic Interface with Motor/Brake System for Colonoscopy Simulation

Hannes Bleuler, Evren Samur, Lionel Flaction, Ulrich Spälter

Training for colonoscopy, which is the examination and treatment of the colon, is often performed on real patients once the physician has passed the novice level. This increases the risk to the patient and lengthens the procedure time. Since a decade ago, ...
