Title (EN) DEVICE FOR MEASURING PARAMETERS REPRESENTATIVE OF THE HANDWRITING SPEED
(FR) DISPOSITIF POUR MESURER DES PARAMETRES CARACTERISTIQUES DE LA VITESSE D"UNE ECRITURE MANUSCRITE
Abstract: front page image
(EN)This device comprises two superposed pairs of sensor coils (1, 2, 5, 6). Each pair is comprised of two series coupled windings, but with opposite winding directions, each winding of a pair being provided with a layer of rectilinear conductive portion (1a, 2a, 5a, 6a), arranged side by side, parallel and superposed to similar portions of the other winding. These two windings extend respectively on either side of the superposed layers thereof. The superposed layers of one pair of windings are normal to those of the other pair. This arrangement is intended to induce in each pair of coils, under the action of a permanent magnet with a flux substantially perpendicular to these windings, fluxes which add to each other when the inductive flux varies in a plane parallel to the coils and which cancel each other when the inductive flux varies perpendicularly to that plane.
(FR)Ce dispositif comporte deux paires de bobines captrices (1, 2, 5, 6) superposees. Chaque paire est formee de deux enroulements couples en serie, mais avec des sens d"enroulement opposes, chaque enroulement d"une paire presentant une nappe de portions conductrices rectilignes (1a, 2a, 5a, 6a) cote-a-cote, paralleles et superposees aux portions analogues de l"autre enroulement. Ces deux enroulements s"etendent respectivement de part et d"autre de leur nappes superposees. Les nappes superposees d"une paire d"enroulements sont orthogonales a celles de l"autre paire. Cet agencement est destine a induire dans chaque paire de bobines, sous l"action d"un aimant permanent a flux sensiblement perpendiculaire a ces enroulements, des flux qui s"additionnent lorsque le flux inducteur varie dans un plan parallele aux bobines et qui s"annulent lorsque le flux inducteur varie perpendiculairement a ce plan.
