20110063604 | OPTICALLY BASED PLANAR SCANNER - Apparatus and methods for providing an optically based planar scanner for generating an image are provided. In one embodiment, the apparatus includes a switchable Bragg grating. An area of the switchable Bragg grating is configured to be activated to direct light to a platen. The platen is configured to reflect the light to a waveguide or to refract the light. The light reflected to the waveguide is guided to a light detector. By activating a number of the areas of the switchable Bragg grating and measuring the intensity of the light with a light detector, an image of an object contacting the platen may be formed. | 03-17-2011 |

20100315499 | LOW SETTLE TIME MICRO-SCANNING SYSTEM - Systems, apparatus, and methods for providing a micro-scanning system with low settle times for fingerprint image capture are provided. In one embodiment, a flexure apparatus includes a stiffening device and parallelogram structures. The flexure apparatus is configured to move an image sensor to different positions to capture images that can be used to form a composite image according to micro-scanning techniques. The stiffening device allows the resonant frequency of the flexure apparatus to be established at a higher level than the operation frequency of the flexure apparatus, minimizing the settle time required for the flexure apparatus. | 12-16-2010 |

20150101575 | Method and Computer Program for Actuating a Fuel Injector - A method actuates a fuel injector having a coil drive with a solenoid and a magnet armature. The magnet armature can be moved along a longitudinal axis by a magnetic field generated by the solenoid. In the method, an amplification voltage is applied to the solenoid at a predefined point in time to move the magnet armature from a closed position into an open position. The amplification voltage is made available by a voltage-regulated direct voltage transformer from a supply voltage. The direct voltage transformer has a storage capacitor for supporting the voltage made available at the output of the direct voltage transformer. The storage capacitor is charged to a pilot control voltage by the amplification voltage before the given point in time, with the result that the voltage present at the solenoid is higher than the amplification voltage at the predefined point in time. | 04-16-2015 |
20150102876 | METHOD FOR ACTUATING AN ELECTROMAGNETIC ACTUATOR DEVICE HAVING A COIL - A method for actuating an electromagnetic actuator device having a coil includes providing a plunger to be activated having at least one section movably disposed in the magnetic field, after activation of the plunger, reducing a voltage again by applying an electrical voltage to end the activation, and after an end of the electrical activation of the plunger, applying a magnetization voltage, which is not sufficient for an activation, to the coil for a predefined time period. | 04-16-2015 |

20080269477 | Solvent System Based on Molten Ionic Liquids, Its Production and Use for Producing Regenerated Carbohydrates - A solution system for biopolymers in the form of carbohydrates based on a molten ionic liquid, additives optionally being contained in the solution system, is described. This solution system contains a protic solvent or a mixture of several protic solvents, and in the case where the protic solvent is solely water, this is present in the solution system in an amount of more than about 5 wt. %. Carbohydrates can be incorporated into the solution system, in particular in the form of starch, cellulose and derivatives thereof, and it can then be used for regeneration of the carbohydrates contained therein. A particularly advantageous process for the preparation of the solution system containing the carbohydrates and for the preparation of regenerated carbohydrates, in particular in the form of regenerated cellulose fibers, is moreover described. The invention accordingly also provides such spun fibers as are distinguished in that they are non-fibrillating. The invention offers in particular economic advantages over the systems of the prior art. | 10-30-2008 |
