Abstract: A method for contactlessly assessing the quality of a solar cell includes performing a first luminescence measurement by applying excitation radiation to a first sub-region of the solar cell per first parameters and to a second sub-region (per second, different parameters. A first intensity of emitted luminescent radiation is measured in the first or second sub-region, and a second measurement measures a second intensity of luminescent radiation. In alternative A, excitation radiation is applied to the first sub-region per the first parameters and excitation radiation is applied to the second sub-region per third, different parameters. The second intensity is measured in the sub-region in which the first intensity is not measured in the first luminescence measurement. Alternative B provides applying excitation radiation homogenously to the solar cell in both sub-regions according to fourth parameters and the second intensity is measured in the first and/or second sub-region.

Abstract: A method is provided for smoothing a surface region of a component consisting of an electrically conductive material. The surface region of the component is coated inside a vacuum chamber, by focused electron beam(s) with a first surface energy, which brings about melting of the component material within the surface region. Before melting, the surface region is passed over at least twice by the electron beam, each time with a different focal length of the electron beam. A second surface energy is set for the electron beam, such that no melting of the component material is brought about in the surface region. Data is recorded by a number of sensors arranged inside the vacuum chamber. An actual value for the roughness is compared to a set point value. If the actual value has not reached the set point value, a value for the first surface energy is determined via comparison.

Abstract: A picture in a data stream is subdivided into different size transform bocks. For a transform block, a transformation is selected by checking whether the block's size exceeds a threshold. If it does, a default technique is used to select the transformation. If it does not, a transformation is used from a list of transformations as identified by an index, the list including an identity transformation and non-identity transformations. A coefficients block in the data stream is decoded, and if the selected transformation is the identity transformation, then the coefficients block is used as a residual sample array, and if the selected transformation is not the identity transformation, the coefficients block is subjected to an inverse transformation corresponding to the selected transformation to obtain a residual sample array used to correct a prediction for the transform block.
