| 20110115544 | BOOTSTRAPPED SWITCH CIRCUIT - A bootstrapped switch circuit can include a switch transistor, having a drain configured as an input terminal to receive an input signal, and a voltage-controlled voltage source, configured to provide predetermined constant voltages between a gate and a source of the switch transistor in response to a control signal received at a control terminal. The predetermined constant voltages can include a first predetermined constant voltage to turn on the switch transistor and pass the input signal to the source and a second predetermined constant voltage to turn off the switch transistor. The first and second predetermined constant voltages can be independent of the magnitude of a signal passed to the source of the switch transistor based on the input signal at the drain. | 05-19-2011 |

| 20090001725 | Method for operation of a converter system - The present invention relates to a method for operating a converter system of a wind turbine, wherein the converter system includes converter modules capable of converting electric power produced by a generator to electric power applicable to a utility grid. The converter modules include generator inverters and grid inverters. The method determines the enabling/disabling of the converter modules in response to a parameter related to the variable amount of electric power being produced by the generator. Advantages of the present invention are optimisation of power efficiency of the converter modules and improved reliability of the converter modules. Another advantage is the capability of fast enabling and disabling of the converter modules. | 01-01-2009 |

| 20100300086 | HYDRAULIC CONTROL ARRANGEMENT AND DISTRIBUTION VALVE SECTION - A hydraulic control arrangement and a method for pressure medium supply of hydraulic consumers are disclosed, comprising an LS pump which can be controlled by a pump regulator dependent on the highest load pressure of the consumers. The pressure medium volume flow to each consumer is adjusted using a metering aperture, wherein on controlling a consumer a higher pressure than the load pressure is signaled to the LS pump regulator, so that the LS pump is controlled according to the higher pressure rather than the low load pressure of said consumer. | 12-02-2010 |

| 20090092579 | NOVEL METHOD FOR DOWN-REGULATION OF AMYLOID - Disclosed are novel methods for combating diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloidogenic proteins (proteins contributing to formation of amyloid) such as beta amyloid (Aβ). Immunization is preferably effected by administration of analogues of autologous amyloidogenic polypeptides, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Aβ which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the majority of Aβ's B-cell epitopes. Also disclosed are nucleic acid vaccination against amyloidogenic polypeptides and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic analogues of the amyloidogenic proteins, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations. | 04-09-2009 |
