20100090610 | Control Method, Control Device and Method for Producing the Control Device - A pulsed electric operating current that rises during a pulse duration is generated for operating at least one radiation-emitting semiconductor component. For this purpose, in a method for producing a control device for operating the at least one radiation-emitting semiconductor component, a temporal profile of a thermal impedance representative of the at least one radiation-emitting semiconductor component is determined. A profile of the electric operating current that is to be set is determined depending on the determined temporal profile of the thermal impedance. The control device is furthermore designed such that the profile of the operating current that is to be set is set in each case during the pulse duration. | 04-15-2010 |

20110057755 | MAGNETIC ACTUATOR - A magnetic actuator has a static part and a dynamic part concentrically arranged therein. The static part comprises two permanent magnets and the dynamic part comprises two further permanent magnets. The magnet is oppositely oriented to the further magnets. The magnets are tuned to each other in such a way that the gravity on the dynamic part is compensated by the magnetic force on the dynamic part. The static part further includes a coil with which an additional magnetic field can be generated by which the actuation force can be adapted. | 03-10-2011 |
20110259102 | SPEED SENSOR - A speed sensor has a static part and a dynamic part arranged concentrically inside the static part. The static part has two permanent magnets and the dynamic part has two further permanent magnets. The magnet is oriented reversely to the further magnets. The magnets are tuned to each other so that gravity on the dynamic part is counteracted by the magnetic force on the dynamic part. As a result, the weight of the dynamic part need not be carried by springs and the dynamic part can move freely so that the full stroke can be used for measuring accelerations and the natural frequency is low. The static part further includes a measuring coil for measuring the displacement of the dynamic part and for the radial positioning of the dynamic part this part is connected to the static part by means of leaf springs. | 10-27-2011 |

20110201531 | Method for Treating Hydrocarbon-Bearing Formations with Fluorinated Epoxides - A method of treating a hydrocarbon-bearing formation with a fluorinated epoxide and a treated hydrocarbon-bearing formation. A method of making proppants is also disclosed, which includes combining a plurality of particles with a fluorinated epoxide. The particles comprise at least one of sand, resin-coated sand, ceramic, thermoplastic, clay, bauxite, nut or seed shells, fruit pits, or wood. A particle treated with a ring-opened product of a fluorinated epoxide is also disclosed, wherein the particle comprises one of sand, resin-coated sand, ceramic, thermoplastic, clay, bauxite, nut or seed shells, fruit pits, or wood. | 08-18-2011 |
