  • Measuring instrument and measuring method for identifying properties of a specimen with matched dual source calibration
    Patent number: 5247187
    Abstract: A measuring instrument and a method of measuring including providing an illumination arrangement having a plurality of independent illumination sources, a specimen region for conducting a specimen illuminated by the illumination arrangement, a measuring arrangement detecting radiation influenced by the specimen in the specimen region, the illumination arrangement having a plurality of independent aluminum sources which are energized by separate leads and separate switch elements that are operable to selectively operate either individually or in common for a linearity check.

  • Method and apparatus for signal evaluation of zero-axis crossings
    Patent number: 5107213
    Abstract: For evaluating the essentially-periodic signal sequence of inductive measured-value sensors in view of the appearance of zero-axis crossings, all zero-axis crossings in the sensor signal are identified in a zero-axis crossing branch of an evaluation unit and the significant zero-axis crossings are enabled in a parallel enable branch after logarithmic transformation of the sensor signal.
