20140139804 | System and Method for Characterising Eye-Related Systems - Described herein is a light directing assembly for use in an object analysis system. The light directing assembly includes a plurality of optical relay assemblies. Each optical relay assembly includes at least one optical element configured to relay an interrogation beam from a light transmission system to an object and relay a return beam from the object to the light transmission system, the return beam being generated by reflection or back scattering of the interrogation beam by the object. Each optical relay assembly defines an interrogation angle at which the interrogation beam relayed by the optical relay assembly reaches the object, and an optical path length being the distance from the light transmission system to the object travelled by an interrogation beam via the optical relay assembly. The plurality of optical relay assemblies are further configured such that the optical path length for a given optical relay assembly has a predefined relationship with the optical path lengths of the other optical relay assemblies. | 05-22-2014 |

20150331255 | Lens for Myopic Eye - An ophthalmic lens element includes an upper distance viewing zone and a lower near viewing zone. The upper distance viewing zone includes a central region with a first refractive power for clear distance vision and peripheral regions that are relatively positive in power compared to the first refractive power. The lower near viewing zone has a central region that is relatively positive in power compared to the first refractive power to account for accommodative lag. The powers of the peripheral regions of the lower near viewing zone are one of: i) equal to the power of the central region of the lower near viewing zone, ii) relatively positive in comparison to the power of the central region of the lower near viewing zone. | 11-19-2015 |

20090084161 | HYDROGEN SENSOR - The invention relates to a hydrogen sensor with a radiation source, by means of which electromagnetic radiation is radiated onto a sensor medium, wherein the sensor medium has a transmission coefficient that varies as a function of the concentration of hydrogen in the environment of the sensor medium, and with a detector that detects at least a portion of the radiation transported through the sensor medium. The hydrogen sensor according to the invention is characterized by the fact that a reflector is provided that reflects the radiation transmitted through the sensor medium back to the sensor medium. The hydrogen sensor according to the invention is further characterized by the fact that the sensor medium incorporates clusters containing or consisting of a palladium alloy, yttrium, scandium, at least one lanthanide, at least one actinoide, tungsten oxide and/or vanadium oxide, and/or a mixture or compound of these materials. | 04-02-2009 |

20090282036 | METHOD AND APPARATUS FOR DUMP AND LOG ANONYMIZATION (DALA) - According to one embodiment of the invention, an original dump file is received from a client machine to be forwarded to a dump file recipient. The original dump file is parsed to identify certain content of the original dump file that matches certain data patterns/categories. The original dump file is anonymized by modifying the identified content according to a predetermined algorithm, such that the identified content of the original dump file is no longer exposed, generating an anonymized dump file. The anonymized dump file is then transmitted to the dump file recipient. Technical content and infrastructure of the original dump file is maintained within the anonymized dump file after the anonymization, such that a utility application designed to process the original dump file can still process the anonymized dump file without exposing the identified content of the original dump file to the dump file recipient. Other methods and apparatuses are also described. | 11-12-2009 |
