摘要:
An apparatus for measuring optical properties of transparent materials with a first illumination device which illuminates the material to be investigated along a pre-set illumination path with a pre-set radiation, with a radiation recording space which records radiation passed on by the material to be investigated. The radiation recording space is arranged so that radiation emitted by the first illumination device first strikes the material and then at least for a time an inner wall of the radiation recording space. A radiation detector device is arranged to record radiation reflected and/or scattered essentially only from the inner wall. A second illumination device suitable for emitting modulated radiation also illuminates the inner wall.
摘要:
Radiation is irradiated by an irradiation device at a pre-set angle of incidence with respect to the surface onto the surface to be investigated, and the radiation scattered and/or reflected by this surface arrives at a radiation detector device arranged at a pre-set detection angle with respect to the surface and having an image-recording unit which records black-and-white images, wherein this radiation detector device permits a spatially resolved detection of the radiation reaching it. The irradiation device directs radiation in a first wavelength range onto the surface and the image-recording unit records a first spatially resolved image of this radiation scattered and/or reflected from the surface and the irradiation device directs radiation in a second wavelength range onto the surface and the image-recording unit records a second spatially resolved image of this radiation scattered and/or reflected from the surface.
摘要:
A computer network architecture for making procurement-related information that has been generated on a transaction level available to data warehousing techniques is described. The network includes a transaction processing layer with at least one accounting component with a general ledger data base for centrally storing information contained in accounted-related data sets, a data warehousing layer and an additional data sourcing layer. A duplicator receives the data sets that will be or have been stored in the general ledger data base and delivers duplicates of those data sets that fulfil a predefined criteria in a procurement context. A source data base stores the duplicated data sets on a data line level. An extractor of the data sourcing layer interfaces with the data warehousing layer and selectively moves data contained in data lines or sets of data lines from the source data base to the data warehousing layer.

摘要:
A method for the optical investigation of textured surfaces (10) with the steps: irradiation of radiation onto the surface (10) to be investigated; reception of an image from at least part of the radiation irradiated onto the surface (10) and reflected by the surface (10); location-resolved evaluation of the image recorded and determination of at least one value (K) which is characteristic of this image. According to the invention a parameter (G) which is characteristic of the surface is determined whilst using the characteristic value (K) and whilst using at least one further property (E)—known beforehand or determined—of the surface (10).

A device for examining the optical properties of surfaces includes at least one first radiation device which emits radiation to a surface to be examined at a first predetermined spatial angle, at least one first detector device for capturing the radiation emitted to and reflected back from the surface wherein the first detector device, allowing a local resolution of detected radiation, is positioned at least at a second predetermined spatial angle relative to the surface, and at least one further radiation device or second detector device emitting radiation to the surface to be examined at a third predetermined spatial angle or detecting radiation emitted to and reflected back from the surface.
摘要:
Systems and techniques to generate statistical reports on transactions conducted via an electronic marketplace are based on data extracted from the transaction documents. In general, in one implementation, the technique includes receiving documents sent through an electronic marketplace, and extracting data from the documents. The extracted data may relate to a predetermined statistical category of transactions conducted through the electronic marketplace. The extracted data may be stored for each document, and the stored data may be aggregated according to the predetermined statistical category. In some implementations, a report may be generated that relates to a document flow analysis for documents sent through the marketplace according to the buyer, seller, time period, document type, and/or other parameters.
摘要:
A colour measuring unit (1) comprising a radiation device (2) which emits light onto a surface (9) to be examined, wherein the radiation device (2) comprises at least one semiconductor-based light source (6), and a radiation detector device (12) which receives at least a portion of the light scattered by the surface and outputs a signal characteristic of this light, wherein the radiation detector device (12) allows a spectral analysis of the light impinging thereon. According to the invention, the colour measuring unit comprises at least one sensor device (10) which determines at least one electrical parameter of the light source (6), and also a processor device (14) which outputs from this measured parameter at least one value characteristic of the light emitted by the radiation device (2).
