Abstract: L'invention concerne un système et un procédé portant sur un schéma d'authentification de sécurité et de gestion de clés dans un réseau sans fil multi-saut, basé sur un modèle de sécurité point par point. Le principe repose sur l'adaptation de la hiérarchie de clés 802.11r au réseau maillé de points d'accès. Selon cette approche, un détenteur de clé supérieur (R0KH) dérive et conserve la clé maîtresse appairée supérieure (PMK_0) de chaque dispositif sans fil demandeur, après le processus d'authentification. Tous les points d'accès d'authentificateur adoptent le rôle de détenteur de clé de niveau 1 (R1KH) et reçoivent la clé maîtresse appairée de niveau suivant (PMK_1) du détenteur R0KH. La clé de protection de données du niveau liaison est dérivée de la clé PMK_1 en utilisant le protocole d'établissement de liaison 802.11i à 4 étapes.

Abstract: A vehicle restraint installed within a pit underneath a dock leveler of a loading dock platform includes a single actuator that both extends and raises a barrier into engagement with a vehicle's ICC bar. When the barrier is in a retracted, stored position, the barrier is underneath the dock leveler and behind a front face of the loading dock platform. To engage the vehicle's ICC bar, the single actuator extends to first push the barrier along a first track to an intermediate position. That same actuator then pushes the barrier along a second track to a raised, operative position where the barrier engages and captures the vehicle's ICC bar. A spring coupled to the actuator provides the barrier with freedom to float along the second track to accommodate similar incidental movement of the ICC bar as the vehicle is serviced at the dock.

Abstract: Methods and apparatus for tracking objects in conduits, especially for tracking the movement of a pig in a pipeline, are disclosed. Distributed acoustic sensing is used to obtain signal returns from a plurality of discrete longitudinal sensing portions of a fibre optic cable which is laid along the length of the conduit. The method involves detecting an acoustic signature corresponding to the object moving in the conduit. The acoustic signature may comprise a series of pressure pulses caused by the object traversing joints etc. in the conduit. Preferably the method involves detecting pressure waves caused by the object as it moves through the conduit. Detecting the characteristic pressure wave signal provides discrimination of the object from other acoustic disturbances. In pipeline applications a pig can be tracked in real time, if the pig stops moving an alert can be generated and the location of the pig will be known.
