  • Spectrometer system and a method for compensating for time periodic perturbations of an interferogram generated by the spectrometer system
    Patent number: 10365159
    Abstract: A spectrometer system comprises a scanning interferometer; a drive system mechanically coupled to a movable reflector element of the scanning interferometer and operable to effect reciprocation of the movable reflector element at a plurality, preferably more than two, for example three, different scan speeds; a detector arrangement configured to sample at equidistant time intervals an interferogram formed by the scanning interferometer to generate a sampled interferogram; and a data processor is adapted to acquire a sampled interferogram at each of the plurality of different scan speeds and to perform a relative comparison of the content of the so acquired plurality of sampled interferograms.
    Type: Grant

  • PROCESS CONTROL OF BIOTECHNOLOGICAL PROCESSES
    Publication number: 20110081672
    Abstract: A biotechnological process for conversion of a raw material (100, 200) to a desired product (130, 230) by means of one or more biological or biochemical agents (102, 104, 202) such as microorganisms and/or enzymes characterised in that the amount of one or more of said biological or biochemical agents (102, 104, 202) is controllable by a process control algorithm (124,224) dependent on one or more values of interest related to a process stream. A specific aspect of the invention is the use of a process control algorithm for controlling enzyme addition in biofuel production by fermentation of biomass to alcohols.
