Abstract: The invention relates to a linear drive unit comprising a first and second actuator element, a guiding unit configured to enable a linear relative movement between both actuator elements, a first and second power unit, each attached to the first actuator element and configured to provide the second actuator element with a respective first and second driving force, and a control unit for controlling both power units and configured to control the first and second driving force such that the first driving force can be different from the second driving force. The invention further relates to a telescope comprising a linear drive unit as well as to a method of aligning such telescope.

Abstract: A tensile strain state in semiconductor components is adjusted. A pretensioned (tensile strain) layer is applied to a substrate (FIG. 1, (A)). Bridge structures (FIG. 1, (B)) are introduced in the layers by lithography and etching. The bridges are connected to the layer on both sides and are thus continuous. The geometric shape of the bridges, formed with a cross-section modulation, is determined by the windows (FIG. 1 (C)) in the layer. When the substrate is etched selectively, the bridge is undercut through the windows. The geometric structuring of the cross-section (FIG. 1, (D)) causes a redistribution of the originally homogeneous strain when the bridges are detached from the substrate, with the larger cross-sections relaxing at the expense of the smaller cross-sections, where the pretension is increased. Only a multiplication of stresses (or strain) originally present in the sample is possible, with the multiplication factor determined by lengths, widths and depths, and/or the relationships thereof.

Abstract: A method and system for outputting data to be viewed on a mobile terminal or other device that has requested the data to be displayed from a data provider. This outputting of viewable data includes: 1) identifying the system parameters of the terminal by a) querying the equipment identification code of the terminal, b) determining from a database the relevant system parameters (e.g., available memory space, displayable character sets, resolution of the display, depth of color, Codec capabilities, video and audio bit rates, streaming capability; 2) converting the data to be displayed and maintained in a terminal-independent data format, into a terminal-dependent data format by selecting a predefined transformation protocol that corresponds to the system parameters of the terminal; 3) executing the transformation of the data to be displayed in accordance with that transformation protocol; and 4) transferring the data to the terminal.
