    摘要: Compounds of formula I ##STR1## in conjunction with compounds that donate acid when exposed to actinic radiation, are suitable for use as positive photoresists. In formula I, R.sup.1 and R.sup.2 are hydrogen, alkyl, aryl, cycloalkyl, aralkyl or alkaryl, R.sup.3 to R.sup.8 are hydrogen or lower alkyl, X is --O-- or --NR.sup.9 --, where R.sup.9 is hydrogen or C.sub.1 -C.sub.4 alkyl n is 0 or 1, m is 2, 3 or 4 and Q is an organic radical of valency m.The photoresists are suitable for making printing formes, printed circuits, integrated circuits or silver-free photographic films.

    摘要: An antenna coupler for testing a mobile-radio device with a coupling element formed in a flat manner by strip conductors on a printed-circuit board and with a retaining device formed on a first side of the printed-circuit board for positioning a mobile-radio device in the vicinity of the coupling element. On the first side of the printed-circuit board, at least one slit structure is introduced into an ground metallization formed there. For feeding the slit structure serving as the coupling element, at least one stripline formed on the second side facing away from it forms a microstripline with the ground metallization remaining between the slit structure of the first side.

    摘要: The method for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha comprises—for each of a multitude of points (12) on said surface (14)—the step of using a chromatic coded distance measurement technique for determining a distance value (40) representative of a distance to said point (12); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (40). The system for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha, comprises a distance measurement unit for determining—by means of a chromatic coded distance measurement technique and for each of a multitude of points (12) on said surface (14)—a distance value (40) representative of a distance to said point; and a reconstructing unit (50) operationally connected to said distance measurement unit for reconstructing said three-dimensional shape based on said multitude of distance values (40).
