Abstract: A method for measuring substance quantities in a substance mixture including two substances, the method comprises determining a first moisture value for a first of the two substances using a microwave resonator. A second moisture value for the second of the two substances I determined using a microwave resonator. A first measured value and a second measured value are determined for the substance mixture using a microwave resonator. Two scalar factors are determined for two moisture vectors from the first and the second measured values for the substance mixture. The two moisture vectors indicate a direction of a straight line of equal moisture for the first and second substances in a plane of the first and second measured values using the first and second moisture value. A quantity of the first substance and of the second substance in the substance mixture are determined from the two scalar factors.

Abstract: A method is provided for processing at least two starting materials into a final processed product where a predetermined moisture interval is provided for each starting material. The method comprises subdividing each moisture interval into two or more moisture classes and measuring a moisture content for each starting material prior to processing. Each starting material is then assigned to one of the two or more moisture classes and processed depending on the assigned moisture class. A moisture measurement of the final processed product is determined and one or more processing steps are adapted based on the measuring results for the final processed product to achieve a homogeneous moisture distribution in the final processed product.

Abstract: In complex production environments, such as a semiconductor production facility, allocation of test systems for external control is handled on the basis of an allocation system and technique in which enhanced data integrity is ensured. To this end, direct access to facility internal communication resources is prevented, while nevertheless providing external access to the test systems.

Abstract: A method for the measurement of humidity and/or density in a measurement target. The phase and the amplitude of the microwave radiation transmitted through the measurement target is determined for a number of frequencies. The complex-valued transmission function of the measurement target is calculated from the determined values using the complex-valued transfer function of the measurement arrangement, and transformed into the time domain as a complex-valued time domain function. The point in time at which the amount of the main pulse has its maximum value is determined as a characteristic variable A from the time domain function. From the time domain function, the width of the main pulse is determined as a characteristic variable B, and/or the amplitude value of the main pulse as a characteristic variable H. A humidity and/or density of the measurement target is determined depending on the characteristic variable A and the characteristic variables B and/or H.
