Publication number: 20080018741Abstract: The invention relates to the transmission of image data during which first image data are continuously generated by a first computer (PC1) and are or can be displayed in the form of a first temporal sequence of first images on an image display device of the first computer. At least a partial number of the first images are continuously acquired and corresponding second image data are generated therefrom and transmitted to a compression device (CO). The second image data are compressed by the compression device for a data transmission whereby resulting in the generation of third image data, whereby second image data are continuously taken into consideration during compression that correspond to a portion of the first sequence with a number of the first images. The third image data are output to a data transmission device (PR) that generates data transmission signals corresponding to the third image data.Type: ApplicationFiled: June 30, 2005Publication date: January 24, 2008Applicant: Fraunhofer-Gesellschaft zur Forderung der angewandInventors: Andre Stork, Pedro Santos, Dominik Acri

Publication number: 20070265361Abstract: The invention relates to a method for recycling polyesters or polyester mixtures from polyester-containing waste, in which the polyester or the polyester mixture is dissolved in a solvent and subsequently free-flowing particles are precipitated herefrom with a precipitant. The precipitant is thereby chosen such that subsequent separation of precipitant and solvent is made possible in a simple manner.Type: ApplicationFiled: April 13, 2005Publication date: November 15, 2007Applicant: Fraunhofer-Gesellschaft zur Forderung Der AngewandInventors: Andreas Maurer, Udo Knauf, Gerd Wolz, Michael Frankl, Otto Beck

Publication number: 20070097356Abstract: The present invention relates to a method and a device for three-dimensionally determining the refractive index and, if necessary, the layer thickness of transparent or partially transparent layers in which the layer (1) is irradiated at different angles of incidence (5) with polarised light, and variations in the polarisation of the light are measured and evaluated as the light passes through the layer (1). The method is characterised in that the measurement is carried out through an immersion medium (3) between which the layer (1) is inserted. A highly accurate determination of the refractive index of anisotropic thin layers in all three spatial directions is made possible by this method.Type: ApplicationFiled: June 1, 2004Publication date: May 3, 2007Applicant: Fraunhofer-Gesellschaft zur Förderung der angewand ten Forschung e.V.Inventors: Joachim Stumpe, Christoph Jung, Olga Kulikovska

Publication number: 20070081249Abstract: The invention relates to an optical system for reducing the reflection of optically transparent substrates. A layer system consisting of alternately arranged layers is formed on the surface of the respective substrate. The aim of the intention is to reduce the proportion of reflected light within a broad wavelength range, whereby it is possible to have a specific influence upon the value of the reflection, the respective wavelength range wherein a reduction is obtained, and, optionally, upon a colour impression arising therefrom. According to the invention, the alternately arranged layers of materials having lower and higher optical refraction indexes form stacks of layers. Said stacks of layers have an equivalent optical refraction index, in relation to a predefinable wavelength lambda, which is lower than the optical refraction index of the substrate.Type: ApplicationFiled: September 13, 2004Publication date: April 12, 2007Applicant: Fraunhofer-Gesellschaft Zur Forderung Der AngewandInventors: Ulrike Schulz, Norbert Kaiser, Uwe Schallenberg

Publication number: 20070058230Abstract: A laser scanner is provided with a transmission optic (20) whose laser pencil beam (18) is oriented coaxially with the axis of rotation (28) of a deflecting mirror (22, 24) and coaxially with the optical axis of the associated detector optic (58). The arrangement is such that light reflected by a distant measuring point (44) can be deflected by the deflecting mirror (22, 24) through the detector optic (58) to a signal detector. The output signal (70) of the signal detector can be evaluated to acquire data, particularly spatial coordinates. The transmission optic (20) is disposed in a shading cylinder (22) that is open to the deflecting mirror (24) and extends from the detector optic (58) coaxially with the axis of rotation (28) of the deflecting mirror (22, 24) into the vicinity of the deflecting mirror (22, 24), in order thereby to shade the detector object particularly against stray light that occurs when the laser pencil beam (18) impinges on the deflecting mirror (22, 24, 26).Type: ApplicationFiled: September 6, 2006Publication date: March 15, 2007Applicant: FRAUNHOFER-GESELLSCHAFT ZUR FORDERUNG DER ANGEWANDInventors: Andreas Blug, Claudia Baulig

Publication number: 20070053204Abstract: The invention relates to a confocal microendoscope, in which the diameter of optical fibres at the proximal end (8) of an optical fibre bundle (9) is greater than at the distal end (15). This permits the efficiency of coupling the light of a light source to be increased, without reducing the resolution of the microendoscope. In addition, the proximal ends (8) of the optical fibres (10) are arranged in a grid, for example, by means of a fibre receiving unit (11) that holds the individual optical fibres. A microlens unit (13) can also be provided, said unit allocating a microlens (14) to each optical fibre end.Type: ApplicationFiled: September 10, 2004Publication date: March 8, 2007Applicants: FRAUNHOFER-GESELLSCHAFT ZUR FORDERUNG DER ANGEWAND, KARL STORZ GMBH & CO.
