Abstract: L'invention concerne un inhalateur de respiration contrôlée pour poudre sèche caractérisé par une conception simple, des dimensions réduites et de faibles coûts de fabrication. Ledit inhalateur comporte une double protection de dosage et permet une répartition complète et uniforme de la poudre sèche lors du processus d'inhalation. L'invention vise également à mettre en oeuvre un procédé permettant une répartition pulmonaire complète et uniforme de la poudre sèche à inhaler, dans l'air inhalé. A cet effet, la chambre de stockage est couplée à un transporteur de dosage plongeant dans la zone de transition de manière qu'une quantité prédéterminée de poudre sèche puisse être positionnée à proximité du début de l'unité de conduite d'air, et que l'air traversant l'unité de conduite d'air consécutive présente une forme en méandres tridimensionnelle. L'invention vise également à guider l'air inhalé aspiré par la respiration, au travers d'une unité de conduite d'air, de manière à créer alternativement une accélération et un ralentissement consécutif du courant d'air pour un tourbillonnement et une variation simultanés du sens du courant.

Abstract: A method of controlling uniformity during tire manufacture includes the steps of selecting a target attribute and assigning a target value thereto, measuring the target attribute in a subject tire at a first rotational speed approximating highway speed and measuring in the subject tire indicator attributes a second rotational speed lower than the first rotational speed.  The indicator attributes are condensed via a multivariate process to determine which attributes are the most strongly related to the target attribute. Next a plurality of predictors for the target attribute is determined, each predictor having components including at least one indicator attribute. From the plurality of predictors, at least one best predictor is selected. The measurements for the indicator attributes making up the selected predictor are compared to limit values for the indicator attributes, and, responsive to the comparison, the tire manufacturing process may be controlled to correct any deviation between the measured attribute and the limit value for at least an additional subject tire. Production tires are measured for the components of the selected predictor at the second rotational speed, and a value for the target uniformity attribute is predicted based on the selected predictor for the additional subject tire. The predicted value is compared to the target value to allow for sorting or grading the tires.

Abstract: A method of motion-compensated video encoding that enables a video sequence with a global motion component to be encoded in an efficient manner. A video encoder (600) is arranged to assign macroblocks to be coded to specific coding modes including a skip mode, which is used to indicate one of two possible types of macroblock motion: (a) zero motion, or (b) global or regional motion.  As each macroblock is encoded, a previously encoded region surrounding the macroblock is examined and the characteristics of motion in that region determined. With the skip mode, the macroblock to be coded and a motion vector describing the global motion or regional motion is associated with the macroblock if the motion in the region is characteristic of global motion or regional motion. If the region exhibits an insignificant level of motion, a zero valued motion vector is associated with the macroblock.
