20160025924 | SINGLE-MODE PROPAGATION IN MICROSTRUCTURED OPTICAL FIBERS - The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide. | 01-28-2016 |

20100141740 | Device and Method for Non-Contact Recording of Spatial Coordinates of a Surface - A device and a method for non-contact recording of spatial coordinates of a surface includes a sensor head and a controller connected to the sensor head. The sensor head is designed as a portable hand-held device, a projector and two cameras. The controller is also designed as a portable device, with an electrochemical energy source housed in the controller or in the sensor head for power supply to the sensor head and the controller and no cable connection of the sensor head or the controller is provided to further stationary components of the device. | 06-10-2010 |
20100009446 | BIOLOGICALLY ACTIVE MOLECULES, PARTICULARLY BASED ON PNA AND SIRNA, METHOD FOR THE CELL-SPECIFIC ACTIVATION THEREOF, AND APPLICATION KIT TO BE ADMINISTERED - Biologically active molecules are inactivated for selective activation by target cells by being covalently bonded to one or more peptides each of which has one or more specific amino acid sequences that are selected in respect of enzymes cell-specific for target cells. The bonds, which are broken exclusively by the enzymes cell-specific for the target cells in order to biologically activate the molecules, allow the molecules to remain biologically inactive in cells other than the target cells. The molecules are used for influencing gene expression of preferably sick and infected organs or cells, for example. | 01-14-2010 |
