Event-Driven Continuous-Time Feature Extraction for Ultra Low-Power Audio Keyword Spotting

S. Mourrane, Benoit Larras, A. Cathelin, Antoine Frappé

In the context of autonomous keyword spotting and sound detection, this paper proposes a low power feature extraction unit generating spectrograms that represent a unique signature allowing the classification of audio signals. This system is composed of a continuous-Time digital signal processing...

High temperature gradient micro-sensors for skin-friction measurement in flow control applications

Cécile Ghouila-Houri, Manon Benedito, Eric Garnier, Abdelkrim Talbi, Aurélien Mazzamurro, Romain Viard, Alain Merlen, Philippe Pernod, Thomas Arnoult, Quentin Gallas

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were designed and developed for flow separation control. Based on thermal principle, the transducers measure the amplitude and the sign of skin friction, making them particularly useful for flow separation detection. A...

MEMS High Temperature Gradient Sensor for Skin-Friction Measurements in Highly Turbulent Flows

Cécile Ghouila-Houri, Abdelkrim Talbi, Romain Viard, Quentin Gallas, Eric Garnier, Pascal Molton, Jerome Delva, Alain Merlen, Philippe Pernod

This paper presents and discusses the results obtained with a MEMS (Micro-Electro-Mechanical System) high temperature gradient sensor for time-averaged and fluctuating skin-friction measurements in highly turbulent flows. Designed as a robust wall-mounted suspended hot-wire structure, the micro-...

Wind tunnel integration of Micro-Magneto-Mechanical Systems (MMMS) microvalves for flow control experiments

Thomas Arnoult, Colin Leclercq, Cécile Ghouila-Houri, Aurélien Mazzamurro, Manon Benedito, Romain Viard, Quentin Gallas, Eric Garnier, Denis Sipp, Abdelkrim Talbi, Philippe Pernod

Flow control techniques can be defined as methods changing a flow natural dynamics. The control of a flow can be achieved with actuators affecting the flow momentum. Therefore, a MMMS microvalve was designed and characterized. The micro-actuators have then been integrated to a wind tunnel on the...

6 - Closed loop and stubs

L. Dobrzynski, Housni Al Wahsh, Abdellatif Akjouj, Cécile Ghouila-Houri, Abdelkrim Talbi, Gaëtan Lévêque, El Houssaine El Boudouti

Closed loops with finite open loops attached to the robust zeros of one of their two twin states are the systems investigated in this chapter. Such attached finite loops are called stubs. For simplicity, here only the cases where all the stubs have the same length are considered. This length is...
