25 Mar 2011TL;DR: In this paper, the steering assembly for a two-wheeler comprising a frame, a handlebar and a fork holding a steering front wheel is described, and an elastically deformable component is used to generate torque when the steering rod swivels through at least a given angle.
Abstract: Steering assembly for a two-wheeler comprising a frame, a handlebar and a fork holding a steering front wheel. The steering assembly comprises a head tube rigid with the frame and defining a swivel axis, a steering rod mounted swivelling through the head tube and connected on the one hand to the handlebar and on the other hand to the fork. A torque generation device comprises an elastically deformable component arranged in a space inside the steering assembly and surrounding the steering rod. The elastic component having a first portion that cooperates with the tube and a second portion that cooperates with the rod, so as to create restoring torque when the steering rod swivels through at least a given angle with respect to a neutral angular position corresponding to travel in a straight line.

27 Aug 1986TL;DR: In this article, a device for detecting and tracking light sources, comprising dioptric elements for imaging on an array of electro-optical sensors (32) placed in an image plane of said elements which is close to the focal plane thereof and associated with processing electronic means, was presented.
Abstract: of EP01925521. Device for detecting and tracking light sources, comprising dioptric elements for imaging on an array of electro-optical sensors (32) placed in an image plane of said elements which is close to the focal plane thereof and associated with processing electronic means, the whole of the dioptric elements being assembled in an optical module (10) and said array (32) being contained in a tubular body (22), one of the two faces of the body being placed against the optical module, characterized in that the tubular body is sealingly closed, on said face, by the output dioptric element (20) of the optical module (10) and, on the other of its faces, by an electronic module (14) which contains the electronic means for processing the output signal of the array.

30 Apr 1987TL;DR: In this paper, the author comprend un emetteur muni d'un multiplexeur and un recepteur muni de un demultiplexeur, comprending a trois diodes laser fournissant des faisceaux optiques polarised by trois longueurs d'onde.
Abstract: Le dispositif comprend un emetteur muni d'un multiplexeur et un recepteur muni d'un demultiplexeur. Le multiplexeur comporte au moins trois diodes laser fournissant des faisceaux optiques polarises a trois longueurs d'onde λ₂, λ₃, λ₄. Sur le trajet λ₂ est interpose un ensemble comportant une lame (16) quart d'onde pour la longueur d'onde (2λ₂ - λ₄), un filtre (18) de transmission de la longueur d'onde λ₂, une lame (20) quart d'onde pour la longueur londe λ₄ et un polariseur (22), la diode de longueur d'onde λ₂ etant orientee pour que son faisceau soit transmis par le polariseur. La longueur d'onde λ₄ est dirigee sur le polariseur a 90° de la longueur d'onde λ₂ et avec la meme polarisation. La longueur d'onde λ₃, intermediaire entre λ₂ et λ₄, est dirigee sur le polariseur (22) a l'oppose de la lumiere d'onde λ₄ et avec une polarisation de meme sens, de facon que la lumiere de longueur d'onde λ₃ soit reflechie suivant un trajet coaxial au trajet de sortie des longueurs d'onde λ₂ et λ₄.

19 Jan 1988TL;DR: In this article, the authors proposed a lens for forming an image on a detector having an array of sensors, consisting of several sectors having different focal lengths but whose principal planes are at the same locations.
Abstract: The device comprises a lens (12) for forming an image on a detector (10) having an array of sensors. The lens consists of several sectors having different focal lengths but whose principal planes are at the same locations. The signals provided by the detector are applied to digital processing means intended to improve contrast.

22 Mar 2000TL;DR: In this article, a vehicule automobile a au moins de two lignes (26, 28) de sieges, en arrire d'une planche de bord (24), and de two panneaux lateraux (16, 18) du vehicle, un premiere ligne, a vehicle conducteur (30) and un siege conducteur avant passager (32) were deployed sur un plancher (14).
Abstract: Vehicule automobile a au moins deux lignes (26, 28) de sieges
disposes sur un plancher (14), en arriere d'une planche de bord (24),
entre deux panneaux lateraux (16, 18) du vehicule, un premiere ligne
comportant un siege conducteur (30) et un siege avant passager (32)
separes par une console centrale (34) et au moins une seconde ligne
de sieges (28) comportant deux sieges arriere passager (36, 38)
separes par un espace central vide (40), chaque siege comportant une
assise (30a, 32a, 36a, 38a) et un dossier (30b, 32b, 36b, 38b) qui peut
etre rabattu sur cette assise, les sieges de la seconde ligne (28) etant
montes a pivotement pour etre rabattus dans ou contre les panneaux
lateraux (16, 18) du vehicule et le siege avant passager (32) etant
monte a deplacement longitudinal pour etre pousse sous la planche
de bord (24) dans une cavite (68) pratiquee pour la recevoir.
Avantageusement, la console centrale est aussi montee a deplacement
longitudinal pour etre poussee sous la planche de bord (24) dans cette
meme cavite (68). Application a des vehicules urbains comme a des
vehicules de grande habitabilite.
