Filed: 2003-09-16
Abstract: Cette invention concerne un procédé d'obtention de communications dans un système à identification par radiofréquence (RFID) (30) qui comprennent un lecteur (32) et une étiquette RF (44) comportant une mémoire (50) conçue pour stocker des informations. Ce procédé consiste à envoyer, à partir d'un lecteur (32), un message à l'étiquette (44), laquelle, en réponse au message, génère une de sollicitation et l'envoie au lecteur (32); dans un ordre quelconque. Le lecteur (32) effectue une opération mathématique sur la valeur de sollicitation à partir d'une valeur clé (66, 68) afin de générer une réponse à la sollicitation et l'envoie à l'étiquette (44). L'étiquette (44) calcule indépendamment une réponse à la sollicitation en fonction de la valeur clé (66, 68) et de l'opération mathématique. L'étiquette (44) compare la réaction à la sollicitation qu'elle a calculée à la réponse à la sollicitation transmise par le lecteur (32) et authentifie ledit lecteur (32) si la réaction à la sollicitation est conforme à la réponse à la sollicitation. L'invention concerne un système RFID (30) comprenant une étiquette RFID (44) et un lecteur (32) conçus pour s'acquitter des opérations susmentionnées.

Patent CA-2512171-A1 (CA)
Title: Power tong with linear camming surfaces
Inventor: KATHAN MURRAY
IPC: B25B13/50
Filed: 2005-07-14
Abstract: In a pivoting jaw power tong, each primary camming surface of the rotary gear has a substantially linear rather than curved configuration. Each primary camming surface forms an acute angle with a radial line extending from the rotary gear centerline to the point where the primary camming surface transitions to its associated neutral recess. Accordingly, the radial distance to a point on any of the primary camming surfaces reduces linearly with increased distance from the neutral recess. Rotation of the rotary gear in either direction away from the neutral position thus results in a linearly progressive reduction in the distance from the center of rotation to the points where the pivoting jaws' cam followers contact the camming surfaces, thus increasing the force exerted by the dies of the jaws upon a tubular disposed within the jaws. This camming surface geometry allows the power tong to automatically adjust for wear in the mechanism such that the contact force between the rollers and the camming surfaces, and the gripping force applied by the dies, will be substantially uniform.

Inventor: PLACKO DOMINIQUE
IPC: G01N27/90
Filed: 2004-06-24
Abstract: The invention relates to a quantitative magneto-optical imaging method and device which are used to form an image of a target material (2). According to the invention, an active material (15) is used in order to produce a Faraday rotation in a polarised light beam. Said material is placed close to the target material (2) that is to be imaged. The Faraday rotation of the active material (15) is essentially proportional to the magnetisation when it is subjected to an excitation magnetic field. Moreover, photo-detector means (7) detect the beam reflected after passing through the active material. The light from the reflected beam can then be analysed in order to deduce the amplitude and the phase of a disturbance magnetic field created by a defect in the target material (2) subjected to the excitation magnetic field.
