Abstract: The invention relates to a shaping insert (1) for garments for supporting a woman's bust. The aim of the invention is to provide as much bend resistance as possible in the plane stressed by the insert and as much flexibility as possible in relation to bending stresses perpendicular thereto. At the same time, the insert should be as economical as possible to produce. To this end, the insert is configured with at least two insert elements (2, 3) which are arranged essentially one behind the other in the direction perpendicular to the plane which is stressed by the insert. The two insert elements are curved essentially identically either side of the bottom of the insert.

Abstract: A method and apparatus for detecting an etching endpoint of a film on a substrate whereby a first excitation beam of light having a prescribed wavelength is provided, the first light beam substantially containing only a first harmonic component of light at that wavelength. The first light beam is directed at a prescribed incident angle to an interface between the film and the substrate, the first light beam being reflected off the interface to thereby provide a second light beam, the second light beam containing the first harmonic component of the first light beam and a generated second harmonic component. The generated second harmonic component is detected and a first output signal representative thereof is provided. A generated second harmonic component reference of the first light beam is produced and a second output signal representative of a generated second harmonic component reference is provided.
