Abstract: Multi-channel self-interference cancellation is provided in relayed electromagnetic communication (Fig. 4) between a first device and one or more other devices on one or more shared frequency channels. Specifically, near signals are generated at the first device and transmitted to a relay station. A composite signal is received at the first device from the relay station containing relayed versions of the near signals and relayed versions of remote signals transmitted from the one or more other devices, the composite signal having frequency channels including the one or more shared frequency channels, each shared frequency channel occupied by at least one of the relayed near signals and one of the relayed remote signals. One or more cancellation signals are selectively generated, each having a frequency band corresponding to one of the shared frequency channels. The cancellation signals are combined with the composite signal to produce a desired signal representing the relayed remote signals.

Abstract: L'invention concerne une matière absorbante germicide utilisée dans des paquetages chirurgicaux, des bandages, des tampons hygiéniques et dans la prévention et/ou le traitement d'escarres de décubitus, ladite matière se présentant sous forme d'une matrice semblable à de la mousse à base d'un polymère de polyuréthanne hydrophile, à laquelle ont été appliquées des charges spécifiques d'applications d'un colorant désinfectant germicide. Un polyuréthanne hydrophile de diverses densités et épaisseurs présente une capacité exceptionnelle à absorber différents niveaux d'un certain nombre de colorants désinfectants, basiques et acides, tels que le violet de gentiane et le bleu de méthylène. Le rapport entre des utilisations spécifiques d'applications et de charges de colorants permet l'utilisation d'un tampon de violet de gentiane totalement lié comme tampon ou bandage traditionnel sur une blessure superficielle avec la capacité de prévention de l'incursion d'agents pathogènes externes dans la blessure à travers le tampon, les agents pathogènes étant tués par le colorant lié. L'exsudat de la blessure est absorbé de manière sûre par le tampon, des agents pathogènes provenant de la blessure étant également tués. Lorsque la concentration du colorant chargé est saturée par un excès de la limite du colorant lié, le colorant libre limité est disponible pour être administré à la blessure, notamment, aux blessures profondes, en vue de tuer rapidement des agents pathogènes dans la blessure. Le tampon d'administration de colorant libre peut alors être remplacé par le tampon de colorant lié, de façon à absorber l'exsudat de la blessure.

Abstract: A method of improving germination rate in pesticide-treated plant seeds involves forming a pesticide-free polymer coating on a plant seed before treating the seed with a pesticide, where the type of polymer and the coating thickness are designed to block phytotoxic contact of the pesticide with the seed while allowing sufficient transfer of oxygen to maintain the seed's viability and sufficient transfer of moisture under environmental conditions normally encountered by the seed after planting to enable its germination; and then treating the coated plant seed with a pesticide. Seeds that have been treated by this method, and plants that are grown from the treated seeds are also described.

Filed: 2004-09-16
Granted: 2011-08-09
Abstract: A process for depositing a substantially pure, conformal metal layer on one or more substrates through the decomposition of a metal-containing precursor.  During this deposition process, the substrate(s) is maintained at a temperature greater than the decomposition temperature of the precursor while the surrounding atmosphere is maintained at a temperature lower than the decomposition temperature of the precursor. The precursor is dispersed within a transport medium, e.g., a vapor phase. The concentration of the metal-containing precursor(s) in the vapor phase, which also contains liquid therein, can be at a level to provide conditions at or near saturation for the metal precursor(s). In ensuring the aforementioned temperature control between the transport media and substrate, and in maintaining saturation conditions for the transport media, the quality of the deposited metal thin film is markedly improved and the production of by-product metal dust is greatly reduced or substantially eliminated.

Title: Flexible polyurethane foam
Inventor: FREI HANS
IPC: C08G18/48
Filed: 2005-05-12
Granted: 2011-07-05
Abstract: Flexible polyurethane foam is made by mixing prepolymer with foam-forming ingredients comprising isocyanate and water which react to give carbon dioxide. The prepolymer is hydroxyl-tipped, being made by reacting polyol with less than the theoretical proportion of isocyanate required to react with available hydroxyl groups of the polyol. The prepolymer is a new storage stable starting material for use in making flexible polyurethane foam, and the foam produced with the prepolymer has advantageous properties with regard to hydrolysis resistance. The prepolymer may be made with low or high viscosity by appropriate selection of the proportion of isocyanate which reacts with the polyol. At high viscosities cell structure can be advantageously controlled by appropriate gasification or degasification during foaming.
