Abstract: Method for shaping a film/sheet, particularly for making three-dimensional shapes in it, in which case the outlines of the shape to be formed are warmed/heated and the film/sheet is stretched along the heated outline, in order to cause the part of the film/sheet inside it to deviate from the plane of the surface. The heated outlines are created by, for example, directing a moving beam of thermal radiation onto it. A countersurface is provided to limit the stretching and ensure that rupture does not occur. By repeating the procedure sequentially, a great variety of shapes may be created.

Abstract: Method for touch-free operation, in which light is transmitted and the reflected component of the transmitted light is received, in order to active a function. The light is sent from at least two directions, in such a way that the light beams intersect at essentially the desired operating area and the desired intended function is activated only once the light beams are detected from the reflected light. The invention also relates to a device for implementing the method.
