Sensorless Electroacoustic Absorbers Through Synthesized Impedance Control for Damping Low-Frequency Modes in Cavities

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet

This paper presents a concept of sensorless electroacoustic absorber for damping the low-frequency modes in a cavity such as a duct or a room. Taking advantage of the reciprocity of the voice coil transducer, it is shown that a synthetic electrical admitta ...

Small-signal transient response and turn-on delay of polariton laser diodes

Raphaël Butté

We present a theoretical description of the small-signal transient response of polariton laser diodes (pol-LDs) based on simplified coupled rate equations describing the exciton reservoir and the ground-state polariton populations. The analytic expressions ...

Geometric beam coupling impedance of LHC secondary collimators

Nicolas Frank Mounet, Benoît Salvant, Alexej Grudiev

The High Luminosity LHC project is aimed at increasing the LHC luminosity by an order of magnitude. One of the key ingredients to achieve the luminosity goal is the beam intensity increase. In order to keep beam instabilities under control and to avoid exc ...

Hand Impedance Measurements During Interactive Manual Welding With a Robot

Aude Billard, Mustafa Suphi Erden

This paper presents a study of hand impedance measurements comparatively across ten professional and 14 novice manual welders, when they are performing tungsten inert gas (TIG) welding interactively with the KUKA lightweight robot arm (LWR). The results sh ...

Ultra Fine-Pitch TSV Technology for Ultra-Dense High-Q RF Inductors

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Josef Weber

We demonstrate that fine-pitch TSV technology can be exploited to fabricate micro-inductors on high resistivity substrate, with record-high inductance per area and preserving their performance at GHz frequencies. We report an extensive experimental study o ...

End-Point Impedance Measurements Across Dominant and Nondominant Hands and Robotic Assistance with Directional Damping

Aude Billard, Mustafa Suphi Erden

The goal of this paper is to perform end-point impedance measurements across dominant and nondominant hands while doing airbrush painting and to use the results for developing a robotic assistance scheme. We study airbrush painting because it resembles in ...

High Frequency Effects of Impedances and Coatings in the CLIC Damping Rings

Eirini Koukovini Platia

The Compact Linear Collider (CLIC) is a 3 TeV e+e- machine, currently under design at CERN, that targets to explore the terascale particle physics regime. The experiment requires a high luminosity of 2x10^34 cm^2 s^-1, which can be achieved with ultra low ...

Toward broadband electroacoustic resonators through optimized feedback control strategies

Hervé Lissek, Romain Boulandet

This paper presents a methodology for the design of broadband electroacoustic resonators for low-frequency room equalization. An electroacoustic resonator denotes a loudspeaker used as a membrane resonator, the acoustic impedance of which can be modified t ...
