Abstract:
Systems and methods are described that reduce the amount of data that is transferred among the components of the system. In one embodiment, the testing system comprises a scanner device such as a computed-tomography (CT) scanner that generates a volumetric representation of a part-under-inspection. The testing system is further configured to identify a region of interest in the volumetric representation, wherein the region of interest may correspond to an area of the part-under-inspection where a defect or flaw may form. The testing system may further format the data of the volumetric representation so the resulting formatted volumetric representation comprises less data than the original volumetric representation.
Abstract:
The present invention relates to a layer arrangement which changes the transmission of light depending on its temperature, where the layer arrangement has a first polarization layer, a switching layer which influences the polarization properties of light depending on the temperature, and a second polarization layer, as well as an additional NIR transmission-preventing layer.

Abstract:
The invention relates to an electro-optical liquid-crystal display having a realignment layer for realigning the liquid crystals whose field has a significant component parallel to the liquid-crystal layer and which contains a liquid-crystalline medium of positive dielectric anisotropy, where the medium comprises at least one mesogenic compound of the formula II ##STR1## in which R.sup.1 is H, an alkyl or alkenyl radical having 1 to 15 carbon atoms which is unsubstituted or monosubstituted or polysubstituted by halogen and in which one or more CH.sub.2 groups may each, independently of one another, be replaced by --O--, --S--, --CO--, --COO--, --OCO-- or --OCO--O-- in such a way that O atoms are not linked directly to one another.

Abstract:
A layer arrangement (1) which changes the transmission of incident light depending on its temperature, where the layer arrangement (1) has a first polarization layer (5a), a switching layer (2) which influences the polarization properties of light depending on the temperature, and a second polarization layer (5b), whereby both the first polarization layer (5a) and the second polarization layer (5b) are arranged to affect polarization both in the VIS region and in the NIR region.

The present invention relates to a layer arrangement which changes the transmission of light depending on its temperature, where the layer arrangement has a first polarisation layer, a switching layer which influences the polarisation properties of light depending on the temperature, and a second polarisation layer, as well as an additional NIR transmission-preventing layer.
Abstract:
Non-destructive testing and examination systems and methods generate models and other representations of a part. These models can be used to perform analysis such as defect detection and categorization. The present disclosure identifies, in one embodiment, a method and system that identifies particular locations on the part for analysis. These locations correspond to regions of a reference model, which may comprise a representation of the part that a computer aided design (CAD) package can generate. The method provides for test parameters to be assigned or associated with the region so as to direct and instruct the execution of the relevant part analysis protocols. In one example, the test parameters identify criteria for one or more types of defects that may be found on the part.
