An acoustic multi-touch sensing method using amplitude disturbed ultrasonic wave diffraction patterns
TypeArticles dans des revues avec comité de lecture
This paper proposes an acoustic multi-touch tactile sensing method. The proposed method is based on an amplitude disturbed ultrasonic wave diffraction pattern. An A0 Lamb wave transmitted in a thin finite copper plate is processed to provide tactile information, for one or two fingers. A touch event is localized by identifying the diffraction signals among a database of diffracted Lamb wave references. Statistic models are used to improve the localization reliability. An artificial silicone finger is used in the calibration procedure. This touch interface is evaluated as a 2-touch interface.

Application of a Combined Active Control and Fault Detection Scheme to an Active Composite Flexible Structure. MECHBAL, Nazih; VERGÉ, Michel; COFFIGNAL, Gérard; GANAPATHI, Manickam (Elsevier, 2006)In this paper, the problem of increasing reliability of active control procedure is considered. Indeed, a design method of rejection perturbation in presence of potentially faults, on a flexible structure with integrated ...
Corrosion mechanism of a Ni-based alloy in supercritical water: Impact of surface plastic deformation PAYET, Mickaël; MARCHETTI, Loïc; TABARANT, Michel; CHEVALIER, Jean-Pierre (ELSEVIER, 2015)Ni–Fe–Cr alloys are expected to be a candidate material for the generation IV nuclear reactors that use supercritical water at temperatures up to 600 °C and pressures of 25 MPa. The corrosion resistance of Alloy 690 in ...
