Abstract: L'invention concerne un procédé de mise en service d'un système de gestion de pannes pour un réseau d'accès faisant partie d'un réseau public de télécommunications. Dans le réseau d'accès, des lignes d'arrivée sous forme de paires de fils de cuivre s'étendent depuis un commutateur local (10) à travers une série de noeuds vers un équipement terminal conçu pour un utilisateur du réseau. Ce système de gestion de pannes comprend une tête de contrôle (104) et un système (102) de gestion du réseau d'accès. Toutes les nuits, la tête de contrôle (104) effectue une série de contrôles sur chacune des lignes d'arrivée. Les résultats de ces contrôles sont transmis au système (102) de gestion du réseau d'accès. Ces résultats sont ensuite convertis en notes de circuit, dont chacune indique la qualité de fonctionnement du circuit contrôlé. Les notes des circuits contrôlés traversant le noeud sont combinées pour chaque noeud, de manière à produire une note de noeud indiquant la qualité de fonctionnement du noeud. Dans le but d'identifier le noeud dont la qualité de fonctionnement est la pire et qui a besoin, par conséquent, d'être inspecté, les noeuds sont classés en fonction de leurs notes. Quand un client informe d'une panne, la tête de contrôle (104) effectue une série de contrôles sur la ligne du client et transmet les résultats au système de gestion (102). Ce système (102) vérifie les résultats du contrôle afin de déterminer la présence d'une panne éventuelle et identifie les noeuds à travers lesquels passe la ligne. Puis il évalue, pour chacun des noeuds identifiés, une note pour chacun d'un ensemble de facteurs et combine ces notes, de façon à produire une note combinée représentant la vraisemblance de la panne soupçonnée au niveau du noeud. Afin de contribuer à identifier le noeud provoquant la panne soupçonnée, les noeuds sont classés d'après leurs notes combinées.

Abstract: A magnetoelastic torque sensor (2) for providing an output signal (24) indicative of the torque applied to a member about an axially extending axis of the member (11), comprising, a first magnetoelastically active region in the member, the region being magnetically polarized in a single circumferential direction and possessing sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the magnetoelastically active region produces a magnetic field varying with the torque. Magnetic field sensors are mounted proximate to the magnetoelastically active region (ABC) and oriented with respect thereto to sense the magnitude of the magnetic field at the sensors (6) and provide the output signal in response thereto (24). At least the magnetoelastically active region of the member is formed of a polycrystalline material wherein at least 50 % of the distribution of local magnetizations lie within a 90 ~C quadrant symmetrically disposed around the single circular direction and having a coercivity sufficiently high that the field arising from the magnetoelastically active region does not magnetize regions of the member proximate to the magnetoelastically active region to give rise to parasitic magnetic fields which are of sufficient strength to destroy the usefulness, for torque sensing purposes, of the net magnetic field seen by the magnetic field sensor means.

Abstract: An apparatus for deploying an air bag through an automotive dash panel (12) includes an air bag door (16) integrally formed in the panel and defined by a door perimeter including a frangible edge (18) of reduced cross section. A  dispenser (20) supports the air bag (24) behind the door. A metal reaction plate (28) is positioned between the air bag (24) and the door (16). When the air bag inflates, it forces the reaction plate (28) to bend around a horizontal hinge line (36). As the reaction, plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers (50) limit how far the door can travel during air bag inflation. A  stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position. A retaining structure may be included to preclude at least a portion of the air bag door from tearing free of the vehicle panel. A  hinge (44) may be embedded in the panel in a position spanning a portion of the door perimeter. A hollow channel may be formed into the panel along the frangible marginal edge to create a substantial strength differential with the door perimeter to promote bending along the hinge and/or to help confine tearing to the frangible marginal edge during air bag deployment.
