Patent CA-2214101-A1 (CA)
Inventor: BICK ULRICH
IPC: G06T7/00
Filed: 1996-03-04
Abstract: L'invention porte sur une technique permettant la détection automatique de lésions sur des images médicales ainsi que sur le dispositif correspondant. On segmente des images médicales, des mammogrammes par exemple, que l'on traite éventuellement par un renforcement périphérique et/ou un filtrage médian modifié. On procède à une chirurgie morphologique ouverte (104, 106) ainsi qu'à un filtrage à l'aide d'un filtre de masse modifié (107, 109) aux fins de la détection initiale de lésions circonscrites. On fait correspondre des lésions à des descripteurs de Fourier (110, 112) à l'aide d'un gabarit déformable de forme et l'on procède à la caractérisation de la concordance par un recuit simulé ainsi que par la mesure des caractéristiques de circularité et de densité de la lésion suspectée. On procède de manière itérative selon une résolution spatiale différente dans laquelle chaque pas de résolution permet de détecter une taille spécifique de lésion. Cette détection de la lésion conduit à la localisation de la région suspecte et, partant, de la présence vraisemblable d'un cancer.

Title: Air and fuel system for carburetor and fuel injection systems
Inventor: COX CARL C
IPC: F02M31/10
Filed: 1998-06-22
Abstract: An air and fuel system for carburetor and fuel injection engines that regulates the temperature of air and fuel that is mixed in the carburetor or fuel injector prior to introduction to the cylinders of the engine. A heater and associated filter located at the air intake side of the carburetor are activated by circulating heated fluid (coolant) contained within the engine cooling system. The coolant passes through the heater in an isolated chamber or conductor and the fuel line passes inside the coolant line within the heater surroundings so that air and fuel can be temperature regulated. Valves in the fuel line allow for proper mixture of air and fuel. A filter is sized to fit inside or outside the heater, and the heater and filter are encompassed by a cover to hold the components together.      Oxygen is introduced to the system to reduce air pollution and oxygen and fuel vapors combine to create a high explosive fuel that burns efficiently and thereby reduces air pollution.
