Improving Modeling of MEMS-IMUs Operating in GNSS-denied Conditions

Jan Skaloud, Stéphane Guerrier, Yannick Stebler

Stochastic modeling is a challenging task for low- cost inertial sensors whose errors can have complex spectral structures. This makes the tuning process of the INS/GNSS Kalman filter often sensitive and difficult. We are currently investigating two approa ...

Multi-parametric Evaluation of Sit-to-Stand and Stand-to-Sit Transitions in Elderly People

Kamiar Aminian, Anisoara Ionescu, Raluca Lidia Ganea

The aim of this study was to extract multi-parametric measures characterizing different features of sit-to-stand (Si-St) and stand-to-sit (St-Si) transitions in older persons, using a single inertial sensor attached to the chest. Investigated parameters we ...

ESD testing and combdrive snap-in in a MEMS tunable grating under shock and vibration

Herbert Shea, Robert Andrew Lockhart, Subramanian Sundaram, Maurizio Tormen

This work describes a method for tracking the dynamics of electrostatic discharge (ESD) sensitive MEMS structures during ESD events, as well as a model for determining the reduced combdrive snap-in voltage under vibration and shock. We describe our ESD tes ...

Design and assessment of an electrodynamic loudspeaker used in a variable acoustic lining concept

Hervé Lissek, Anne-Sophie Moreau

The acoustic impedance at the diaphragm of an electroacoustic transducer can be modified using a range of active control strategies, amongst which is “direct impedance control”. This technique employs a combination of feedbacks, one on the acoustic pressur ...

Fabrication of polymeric micro structures by controlled drop on demand inkjet printing

Jürgen Brugger, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Loïc Jacot-Descombes

Well controlled spherical microstructures could enable several novel MEMS devices. However, micro machining of spherical shapes has proven to be difficult with conventional planar microfabrication processes [1]. This paper presents a method allowing to fab ...

Noise reduction and estimation in multiple micro-electro-mechanical inertial systems

Jan Skaloud, Stéphane Guerrier, Adrian Wägli

This research studies the reduction and the estimation of the noise level within a redundant configuration of low-cost (MEMS-type) inertial measurement units (IMUs). Firstly, independent observations between units and sensors are assumed and the theoretica ...

A Minimalist Control Strategy for Small UAVs

Dario Floreano, Jean-Christophe Zufferey, Severin Leven

Most autopilots of existing Miniature Unmanned Air Vehicles (MUAVs) rely on control architectures that typically use a large number of sensors (gyros, accelerometers, magnetometers, GPS) and a computationally demanding estimation of flight states. As a con ...

Vision-based control of near-obstacle flight

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

This paper presents a novel control strategy, which we call optiPilot, for autonomous flight in the vicinity of obstacles. Most existing autopilots rely on a complete 6-degree-of-freedom state estimation using a GPS and an Inertial Measurement Unit (IMU) a ...
