Abstract: An instrument for measuring the size distribution of a particle sample by counting and classifying particles into selected size ranges. The particle concentration is reduced to the level where the probability of measuring scattering from multiple particles at one time is reduced to an acceptable level. A light beam is focused or collimated through a sample cell, through which the particles flow. As each particle passes through the beam, it scatters, absorbs, and transmits different amounts of the light, depending upon the particle size. So both the decrease in the beam intensity, due to light removal by the particle, and increase of light, scattered by the particle, may be used to determine the particle size, to classify the particle and count it in a certain size range.

Abstract: One method embodiment executes a director. The director invokes at least one “active stamp” when processing data, where each of the active stamps relates to a different data manipulation method. The active stamps comprise specialized, portable and dynamic logic processes generically applicable to a plurality of different directors such that each of the active stamps can be individually invoked by each of the different directors to perform the same operation for each of the different directors. The invoking of the active stamps by the director calls the active stamps from a resource in a structure that allows each of the different directors to individually access each of the active stamps that correspond to a current data manipulation process being invoked by each of the different directors. Because the director calls the active stamps at run time of the processing of the data, the active stamps avoid having to be compiled with the director.
