20110094566 | Luminescence Concentrators and Luminescence Dispersers on the Basis of Oriented Dye Zeolite Antennas - A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it. This results in completely novel usage possibilities for collecting and concentrating sun light and feeding it into photovoltaic systems, for converting it into electric and thermal energy in combined photovoltaic/hot water apparatuses, and for feeding it into fiber optic apparatuses. | 04-28-2011 |
20140328761 | Local J-Coupling Dye-Zeolite Antenna Composite Materials - A dye loaded zeolite composite material comprises a plurality of zeolite crystals each having a plurality of straight through uniform channels extending between the proximal face and the distal face and having a channel axis parallel to and a channel width transverse to a longitudinal crystal axis A. Each channel contains a substantially linear arrangement of dye molecules comprising first and second dye molecules having an elongated shape with a longitudinal extension exceeding said channel width and a lateral extension not exceeding said channel width. Each dye molecule consists of a chromophore moiety arranged between a pair of terminal moieties, wherein: the chromophore moieties of the first and second dye molecules are substantially identical, the terminal moieties of the first dye molecules have a lateral extension larger than half of the channel width, the terminal moieties of the second dye molecules have a lateral extension smaller than half of the channel width, the linear arrangement of dye molecules comprises at least one pair of second dye molecules adjacent each other. | 11-06-2014 |

20120056042 | TRACKING ROLLING STOCK IN A CONTROLLED AREA OF A RAILWAY SYSTEM - A system for monitoring the location of rolling stock within a controlled area of a railway system is provided. The system includes a plurality of axle counters within the controlled area, wherein the axle counts are associated with a global sequence identifier. A central controller processes the axle counts and associated global sequence identifier in conjunction with a list of rolling stock entering the controlled area to provide a real time map of the location of each piece of rolling stock within the controlled area. | 03-08-2012 |

20080211353 | HIGH TEMPERATURE BIMORPH ACTUATOR - A bimorph actuator has been found that uses commonly available piezoelectric material and is operational up to about 150° C. or one half of Curie temperature, in that it does not exhibit depolarization due to negative electric fields and/or elevated temperature. This result is accomplished by driving both piezoelectric materials with a positive electric field along the polarization direction. | 09-04-2008 |

20110040514 | METHOD FOR CALIBRATING A COORDINATE MEASURING MACHINE - A reference measurement object having known properties is used for the purpose of calibrating a coordinate measuring machine. A plurality of reference measured values are picked up on the reference measurement object. Calibration data are determined using the reference measured values and using the known properties of the reference measurement object. The calibration data comprises a first number of polynomial coefficients that are selected to correct nonlinear measuring errors using at least one polynomial transformation. The first number of polynomial coefficients is reduced in an iterative method to a lesser second number, with a plurality of pairs of polynomial coefficients being formed and with a polynomial coefficient of a pair being eliminated in each case when a statistical dependence between the polynomial coefficients of the pair is greater than a defined threshold value. | 02-17-2011 |
20110096896 | METHOD FOR THE TOMOGRAPHIC MEASUREMENT OF MECHANICAL WORKPIECES - In a method for measuring mechanical workpieces by tomography, a workpiece and radiation penetrating the workpiece are moved relative to one another step-by-step. A two-dimensional image of the workpiece is generated in an imaging plane from the interaction of the workpiece and the radiation in each movement position of the workpiece. In addition, a three-dimensional representation of the workpiece is computed from the two-dimensional images. From at least two two-dimensional images showing a regular actual structure existing within the workpiece, points at a high-contrast transition are registered. A three-dimensional equivalent body is determined from the position of the points, and said equivalent body is compared to a predefined nominal structure. | 04-28-2011 |
20110191060 | METHOD FOR MEASURING A WORK PIECE, CALIBRATION METHOD AND COORDINATE MEASURING DEVICE - A work piece is measured by at least one point of a surface of the work piece being sampled by a feeler. The feeler exerts a probing force on the surface and the feeler is deflected relative to a mounting of the feeler. On the basis of the deflection, a position of the point of the surface is determined. A directional dependence of a flexibility of the feeler is determined and/or is known. The feeler and the work piece are positioned and/or oriented relative to each other, while taking into consideration the directional dependence, such that during sampling of the point of the surface unintentional slipping of the feeler on the surface does not occur, or occurs only with low probability, or an unintentional deviation of the feeler from an intended path on the surface does not occur, or occurs only with low probability. | 08-04-2011 |
