| 20140084906 | MAGNETIC FIELD SENSOR SYSTEM WITH A BIASING MAGNET PRODUCING A SPATIALLY SYMMETRIC MAGNETIC FIELD WITHIN A PLANE BEING DEFINED BY MAGNETORESISTIVE SENSOR ELEMENTS - A magnetic field sensor system for measuring rotational movements of a shaft is disclosed. The sensor system includes a biasing magnet configured for generating a biasing magnetic field and a magnetic wheel having a wheel axis and a circumferential surface which comprises a regular structure of teeth and gaps arranged in an alternating manner. The magnetic wheel is attachable to the shaft and is magnetizable by the biasing magnetic field. A magnetoresistive sensor arrangement comprising four magnetoresistive sensor elements being connected with each other in a Wheatstone bridge, respectively two of the magnetoresistive sensor elements being assigned to one half bridge of the Wheatstone bridge. The four magnetoresistive sensor elements are arranged within an x-y plane. | 03-27-2014 |

| 20140021941 | MAGNETIC FIELD SENSOR - A magnetic field sensor assembly for measuring an angular direction of a sensed magnetic field relative to the assembly is disclosed. The sensor assembly includes a sensor of a first type configured to sense an orientation of the sensed magnetic field, a sensor of a second type configured to measure an orientation and a direction of the sensed magnetic field and processing circuitry connected to each of the magnetic field sensors. The processing circuitry being configured to process output signals from the sensor of the first type to determine an uncorrected sensed magnetic field angle and to apply an offset angle to the uncorrected magnetic field angle dependent on a logical combination of signs of output signals from the sensors of the first and second types. | 01-23-2014 |

| 20150105315 | Polypeptide Fragments Comprising Endonuclease Activity and Their Use - The present invention relates to polypeptide fragments comprising an amino-terminal fragment of the PA subunit of a viral RNA-dependent RNA polymerase or variants thereof possessing endonuclease activity, wherein said PA subunit is from a virus belonging to the Orthomyxoviridae family. This invention also relates to (i) crystals of the polypeptide fragments which are suitable for structure determination of said polypeptide fragments using X-ray crystallography and (ii) computational methods using the structural coordinates of said polypeptide to screen for and design compounds that modulate, preferably inhibit the endonucleolytically active site within the polypeptide fragment. In addition, this invention relates to methods identifying compounds that bind to the PA polypeptide fragments possessing endonuclease activity and preferably inhibit said endonucleolytic activity, preferably in a high throughput setting. This invention also relates to compounds and pharmaceutical compositions comprising the identified compounds for the treatment of disease conditions due to viral infections caused by viruses of the Orthomyxoviridae family. | 04-16-2015 |
