20100332038 | METHOD FOR CONDITIONING A CONTROL VALVE - A control valve conditioning method in an electrohydraulic pressure control unit comprising at least one electrically triggered solenoid valve that is controlled in an analog manner. The solenoid valve is operated at a specific operating current according to a functional correlation or characteristic diagram between the valve current and the differential pressure characteristic curve when the pressure is controlled, said functional correlation or characteristic diagram being stored in the pressure control unit. The method comprises the following steps: a) temporarily applying at least one anti-hysteresis pulse to the solenoid valve during which a current is set far below or far above the operating current in the valve; b) applying the anti-hysteresis pulse at the desired operating current before or during controlled operation, and c) applying the anti-hysteresis pulse wherein the duration is limited in such a way that the anti-hysteresis pulse has largely no influence on the brake pressure. | 12-30-2010 |

20090276077 | METHOD AND SYSTEM FOR SEMICONDUCTOR PROCESS CONTROL AND MONITORING BY USING PCA MODELS OF REDUCED SIZE - By dividing a complex set of parameters of a production process in forming semiconductor devices into individual blocks, respective PCA models may be established for each block and may thereafter be combined by operating on summary statistics of each model block in order to evaluate the complete initial parameter set. Thus, compared to conventional strategies, a significant reduction of the size of the combined PCA model compared to a single PCA model may be obtained, while also achieving an enhanced degree of flexibility in evaluating various subsets of parameters. | 11-05-2009 |
20100198556 | METHOD AND SYSTEM FOR SEMICONDUCTOR PROCESS CONTROL AND MONITORING BY USING A DATA QUALITY METRIC - During fault detection of a production process, the influence of the data communication process for communicating measurement readings to the fault detection system may be taken into consideration. In one illustrative embodiment, a data rate related parameter may be used as an input variable for a data reduction procedure, thereby enabling an efficient assessment of the quality of the remaining “real” process and tool parameters. | 08-05-2010 |

20090202983 | Method For Determining The Concentration of Virus Particles/Virus Antigens - The invention provides a method for determining the concentration of virus particles and/or virus antigens in a sample. In particular, the invention relates to determining the concentration of influenza virus particles/influenza virus antigens in a sample. The invention further relates to the use of an ion-exchange matrix for the determination of the concentration of virus particles and/or virus antigens in a sample. | 08-13-2009 |
20090304729 | CELL-DERIVED VIRAL VACCINES WITH LOW LEVELS OF RESIDUAL CELL DNA - The present invention relates to vaccine products for the treatment or prevention of viral infections. Further provided are methods of reducing contaminants associated with the preparation of cell culture vaccines. Residual functional cell culture DNA is degraded by treatment with a DNA alkylating agent, such as β-propiolactone (BPL), thereby providing a vaccine comprising immunogenic proteins derived from a virus propagated on cell culture, substantially free of residual functional cell culture DNA. | 12-10-2009 |
20110027314 | Influenza Vaccines Containing Hemagglutinin and Matrix Proteins - An immunogenic composition comprising influenza virus haemagglutinin and matrix proteins. These may be from influenza viruses grown in cell culture rather than eggs. The matrix protein may be a fragment of a full-length viral matrix protein e.g. a matrix M1 fragment with a molecular weight of less than 2 OkDa. The composition may be a subunit vaccine comprising purified surface glycoproteins. | 02-03-2011 |
20140322700 | METHOD FOR DETERMINING THE CONCENTRATION OF VIRUS PARTICLES/VIRUS ANTIGENS - The invention provides a method for determining the concentration of virus particles and/or virus antigens in a sample. In particular, the invention relates to determining the concentration of influenza virus particles/influenza virus antigens in a sample. The invention further relates to the use of an ion-exchange matrix for the determination of the concentration of virus particles and/or virus antigens in a sample. | 10-30-2014 |
