  • Publication number: 20100176102
    Abstract: A method and device for machining material uses laser radiation, in which the unfocused laser radiation is focused through a focusing optics to a smaller beam cross section. The optical axis of the focused laser radiation, referred to as beam axis, is directed at the material surface. The beam waist, which results from the focusing operation, of the focused laser radiation is held in the region of the interface, which forms of laser radiation and material. The laser radiation is partially absorbed on the interface such that due to induced material removal or induced material displacement the interface and thus also the laser radiation penetrate into the material. The spacing of the beam waist from the upper or lower side of the interface in the axial direction corresponds at most to triple the value of the penetration depth of the interface into the material.

  • Publication number: 20100084201
    Abstract: The spatial center of mass and a mass of an object can be determined by orientating the suspended object in at least two different spatial positions and measuring the orientation of the object in each of the different spatial positions the forces acting on the suspension devices because of the suspended object, the forces acting on the suspension devices being resolved into three independent force components. A center of area of the object and the associated force effect lines are determined for each of the at least two spatial positions, the center of area of the respective spatial position being determined with an inclined tension compensation of the suspension devices. The spatial center of mass is determined by superimposing at least two force effect lines.

  • Publication number: 20080311697
    Abstract: The invention relates to a method for simultaneous recrystallisation and doping of semiconductor layers, in particular for the production of crystalline silicon thin layer solar cells. In this method, in a first step a substrate base layer 1 is produced, in a step subsequent thereto, on the latter an intermediate layer system 2 which has at least one doped partial layer is deposited, in a step subsequent thereto, an absorber layer 3 which is undoped or likewise doped is deposited on the intermediate layer system 2, and in a recrystallisation step, the absorber layer 3 is heated, melted, cooled and tempered. In an advantageous method modification, instead of an undoped capping layer, a capping layer system 4 which has at least one partial layer can also be applied applied on the absorber layer 3.

  • Publication number: 20080246973
    Abstract: The present invention relates to a method for determining a lateral relative movement between a processing head and a workpiece during processing the workpiece as well as a device to carry it out. In the method a surface of the workpiece (12) is illuminated in the region of the processing head with an optical radiation (2). The optical radiation (3) reflected from the surface of the workpiece (12) in the region of the processing head is repeatedly detected in a locally resolved manner by an optical detector (9), which is firmly fixed mechanically to the processing head, to obtain optical reflection patterns. The repeated detection occurs in temporal intervals in which the temporally successive reflection patterns of overlapping surface regions of the workpiece (12) are obtained. The lateral relative movement is determined by comparing the temporally successive reflection patterns.

  • Publication number: 20080190903
    Abstract: The invention relates to a method for machining workpieces by using laser radiation, wherein the workpieces to be machined are moved during the machining and at least one laser beam is deflected with respect to two axes aligned orthogonally to one another. It is therefore the object of the invention to form large-area machining contours with as high a machining speed and as great an accuracy as possible. In the method in accordance with the invention, a procedure is followed that a laser beam is deflected within a working field with respect to two axes aligned orthogonally to one another. Positional coordinates of the respective machining contour are moreover associated in an electronic evaluation and control unit with virtual machining segments in which the machining is carried out sequentially.

  • Publication number: 20080192965
    Abstract: In a reproduction area where there are at least three directional groups, each of which has speakers, triggering of the speakers is achieved in that a source path from a first directional group position to a second directional group position is initially obtained along with movement information for the source path. Subsequently, a source path parameter is calculated for different points in time on the basis of the movement information, the source path parameter indicating a position of an audio source on the source path. In addition, a path modification command is received to define a compensation path to the third directional zone, a value of the source path parameter further being stored at a location where the compensation path deviates from the source path, and being used, along with a compensation parameter, for calculating weighting factors for the speakers of the three directional groups.
