Patent CA-2488364-C (CA)
Inventor: BRAM MARTIN
IPC: B22F3/24
Filed: 2003-05-09
Granted: 2011-03-08
Abstract: L'invention concerne un procédé de production de corps moulés métalliques très poreux, comprenant les étapes suivantes : une poudre métallique, utilisée comme produit de départ, est mélangée à un substitut ; une ébauche crue est formée par compression à partir de ce mélange ; cette ébauche crue est soumise à un usinage mécanique classique, ledit substitut augmentant de façon avantageuse la stabilité de cette ébauche ; la matière de substitution est séparée thermiquement de cette ébauche crue à l'air, sous vide ou sous gaz protecteur ; ladite ébauche crue est frittée de manière à former le corps moulé puis polie de façon avantageuse. Parmi les matières de substitution appropriées figurent, par exemple, le bicarbonate d'ammonium ou encore la carbamide. L'usinage mécanique avant le frittage permet une production simple, proche du contour final souhaité, même lorsque le corps moulé à produire présente des géométries complexes, sans altération de la porosité ni usure importante de l'outil. L'avantage est que le demi-produit à usiner est suffisamment stable à la pression pour l'usinage en vert, puisque la matière de substitution est encore présente dans les pores de l'ébauche crue au cours de l'usinage.

Granted: 2012-10-09
Abstract: La présente invention se rapporte à la mesure de la profondeur d'un agent contaminant, p. ex. La neige, présente sur une route ou une piste à partir d'un véhicule en mouvement, en mesurant la distance entre l'endroit où un faisceau lumineux touche la surface supérieure de l'agent contaminant et l'endroit où le faisceau lumineux devrait avoir touché la route ou la piste selon la position de ladite source lumineuse. Pour éliminer les effets de tangage et de roulis des mesures, une seconde source lumineuse fournit un point de référence, d'où les calculs de la profondeur de l'agent contaminant peuvent être effectués, quelle que soit la distance entre la route ou la piste et les sources lumineuses. Un appareil d'enregistrement vidéo, par exemple une caméra numérique, sert à saisir les images des points d'où les distances peuvent être mesurées en ajoutant le nombre de pixels entre les points sur les images. La présente invention peut également servir à déterminer la texture/rugosité de la surface et le coefficient de friction de la route ou de la piste en augmentant la sensibilité de l'appareil d'enregistrement fin de saisir tout changement, aussi petit soit-il, de la position relative des points de référence, et en faisant appel à un traitement complexe des signaux afin de faire correspondre les changements de la position relative des points à la texture/rugosité de la surface.

Title: Method of processing and storing mass spectrometry data
Inventor: MALEK ROBERT
IPC: G06F17/00
Filed: 2004-09-23
Granted: 2011-11-01
Abstract: A data compression technique is disclosed for Fourier Transform Mass Spectrometry (FTMS). A statistical analysis is applied to the data in the frequency domain since most of this data is a result of randomly distributed electronic noise. A fit of the whole frequency dataset to the distribution is made to determine preliminary moments of the distribution. The data in the tail of that distribution (which is mainly the peak data) is then removed and the remaining data points are re-fitted to the distribution, to identify the moments of distribution of that remaining noise data. A noise threshold for the mass spectrum is then applied using the calculated moments. The data above the threshold is kept. The whole spectrum can be reconstituted by storing the moments of distribution along with the peak data and then regenerating the noise from those moments and adding it to the peak data.
