Patent CA-2510681-C (CA)
Inventor: ADAMS MAX H
IPC: H01H83/14
Filed: 2005-06-28
Granted: 2007-03-20
Abstract: A two channel universal device for advanced protection from a short circuit current which evaluates a rate-of-change of current in a supply feeder and compares the current in the supply feeder and the current in load phases generating a differential signal in such a way that in normal conditions, when the load is running or starting, the differential signal is virtually zero. The differential signal and the rate-of-change of current in the supply feeder are compared with the settings of the protective device. If both the value of the rate-of-change of current and the value of the differential signal simultaneously exceed their settings, after an adjustable time delay, the device produces a signal to open the circuit. The existence of two conditions necessary to initiate the trip signal to cause the circuit to open ensures the reliable operation of this device and provides a feasible fast protection scheme.

Abstract: An apparatus is provided for locking a first door of a motor vehicle in place relative to a second door as the first and second doors abut against each other when closed. The apparatus includes a base plate mounted to the first door. A latch release lever is pivotally mounted to the base plate for movement between a neutral position and a release position. In the release position, the latch release lever actuates at least one door latch to release the first door.

Abstract: A technique for efficient representation of dependencies between electronically-stored documents, such as in an enterprise data processing system. A document distribution path is developed as a directional graph that is a representation of the historic dependencies between documents, which is constructed in real time as documents are created. The system preferably maintains a lossy hierarchical representation of the documents indexed in such a way that allows for fast queries for similar but not necessarily equivalent documents. A distribution path, coupled with a document similarity service, can be used to provide a number of applications, such as a security solution that is capable of finding and restricting access to documents that contain information that is similar to other existing files that are known to contain sensitive information.

Granted: 2012-02-21
Abstract: A bearing assembly lockable onto a shaft. The bearing assembly comprises a first tapered adapter defining a first axial bore for the receipt of the shaft which has an outer, annular tapered surface. There is a second tapered adapter defining a second axial bore for receipt of a sleeve portion of the first adapter. The second tapered adapter has an outer, annular tapered surface tapered at a taper angle opposite to that of the first tapered adapter such that the first and second tapered adapters co-operate to define an outer annular surface having a generally V-shaped configuration that tapers from spaced greater diameter outer ends to adjacent lesser diameter inner ends. The opposed tapered surfaces have a fixed limit in their axial travel toward each other along the shaft defined by engagement of the lesser diameter inner ends.  When the tapered surfaces reach the end of their travel, the bearing supported on the tapered surfaces is tightened on the shaft with the correct clearances.

Abstract: Laffichage dune carte sur un dispositif de communication sans fil comprend les étapes suivantes : obtenir les données de la carte pour générer la carte à afficher sur le dispositif de communication sans fil; déterminer une rotation qui, lorsquappliquée à la carte, orientera un chemin sélectionné dans une direction sélectionnée, comme une direction de déplacement actuelle; générer une rotation corrigée en appliquant un facteur de correction sphérique, p. ex. en se fondant sur un emplacement actuel; et générer la carte sur un affichage du dispositif de communication sans fil en y appliquant la rotation corrigée. Le facteur de correction sphérique corrige les distorsions de carte qui surviennent à des latitudes élevées, pour des chemins qui ne sont ni purement nord-sud, ni purement est-ouest. Lorsquun tel chemin subit une rotation pour faire face vers le haut, afin de montrer le sens de déplacement, le chemin doit être redressé par lapplication du facteur de correction sphérique.
