Title (EN) PROCESS FOR MEASURING AND ANALYSING POTENTIALS OF PIEZO-ELECTRICAL ORIGIN GENERATED BY A RIGID MEMBER OF ORGANIC MATERIAL
(FR) PROCEDE POUR MESURER ET ANALYSER DES POTENTIELS D"ORIGINE PIEZO-ELECTRIQUE ENGENDRES PAR UN ORGANE RIGIDE EN UN MATERIAU ORGANIQUE
Abstract: front page image
(EN)This process comprises the detection of piezo-electrical potentials which are characteristic of a mechanical action exerted on a elongated rigid member of organic material. To that effect, potentials are measured at two points remote of this member by means of two operational amplifiers (CI1 and CI2) so as to obtain a characteristic signal of the stress rather than its derivative and these signals are processed by means of analog operators (OA1, OA2, OA3) to identify the flexion stress ((Alpha)F) and the torsion stress (T) which are then compared to reference values (RT, RF) with the aim to, for example, generate a signal. This process may be used particularly to control the opening of a safety ski binding.
(FR)Ce procede consiste a detecter des potentiels piezo-electriques caracteristiques d"une sollicitation mecanique exercee sur un organe rigide allonge en un materiau organique. A cet effet, on mesure des potentiels en deux points eloignes de cet organe a l"aide de deux amplificateurs operationnels (C11) et (C12) afin d"obtenir un signal caracteristique de la contrainte plutot que de sa derivee et on traite ces signaux a l"aide d"operateurs analogiques (OA1, OA2, OA3) pour identifier les contraintes de flexion (F) et de torsion (T) que l"on compare ensuite a des valeurs de reference (RT, RF) en vue par exemple de declencher un signal. Ce procede pourrait notamment etre utilise pour commander l"ouverture d"une fixation de ski de securite.
