Patent CA-2283717-A1 (CA)
Inventor: YOUNG GERALD ALFRED
IPC: A61F13/15
Filed: 1998-03-26
Abstract: La présente invention concerne des noyaux absorbants destinés à êtres insérés dans des articles tels que les couches pour bébé, les protections contre l'incontinence, les culottes de propreté, les supports et les garnitures de couche, les serviettes hygiéniques et articles similaires, lesquels noyaux sont conçus pour améliorer le confort et l'ajustement au corps de l'utilisateur tout en retenant de façon adéquate les écoulements corporels. Les noyaux absorbants sont conçus de manière qu'ils retiennent un faible niveau de fluide dans la zone de l'entrejambes par rapport aux autres zones du noyau, même lorsque le noyau absorbe une importante quantité de fluide au cours de l'utilisation. Pour obtenir ce résultat, le noyau absorbant est conçu de manière que le fluide se déplace dans une large mesure depuis la zone de l'entrejambes vers l'extrémité avant et/ou arrière de l'article. En particulier, le noyau absorbant comprend, dans la zone de l'entrejambes, un matériau de distribution doté d'une grande capacité de reflux même après une longue période de temps. Les propriétés de reflux du matériau reflètent sa capacité à déplacer de grandes quantités de fluide depuis l'entrejambes du noyau, même après de longues périodes de temps (10 et 30 minutes, par exemple).

Patent CA-2284925-A1 (CA)
Title: Bone cement and method of preparation
Inventor: LAUTENSCHLAGER EUGENE P
IPC: A61K6/884
Filed: 1997-11-26
Abstract: Orthopedic bone cements of low porosity, prepared by mixing together at least two liquid components under conditions that allow only minimal exposure to air, are disclosed. In a preferred system, each liquid component consists essentially of a solution of a linear (non-crosslinked) polymer or copolymer of methyl methacrylate (PMMA) dissolved in a non-crosslinking methyl methacrylate (MMA) monomer, with one such solution also containing an activator and a polymerization inhibitor and a second solution containing an initiator as well as a polymerization inhibitor. No reinforcing fillers are present, although a small amount (no more than 12 % by weight of the total cement composition) of a radiopacifier may be included in the composition. Since polymerization is initiated by mixing together two or more liquid solutions, and such mixing may be performed in a mixing chamber in which no air is required or is introduced during the mixing operation, prior problems of cement porosity and weakness resulting from air entrapment are avoided or greatly reduced while the reliability and reproducibility of the mixing operation are greatly improved.

The automatic moisture detecting system (20) includes an optical system (30) for imaging a portion of the windshield (26) onto an image array sensor (32), such as a CMOS active pixel sensor. The voltages of each of the pixels which represents the illumination level is converted to a corresponding gray scale value by an analog digital converter (35). The gray scale values corresponding to the image are stored in memory (38). The spatial frequency composition of the gray scale values are analyzed to determine the amount of rain present. In order to provide a control signal to control the operation of the windshield wipers (40) of the vehicle as a function of the amount of moisture present. The system is also adapted to detect the level of fog both on the interior of the windshield (26) as well as the exterior of the windshield (26). By providing a system for automatically detecting the presence of fog on the interior and exterior of the windshield (26), serious performance limitations of known automatic rain sensors are eliminated.
