A method of controlling and visualizing processes, wherein data are produced by means of at least one task and/or thread, and consumed by means of at least one further task and/or thread, is designed with respect to a deterministic behavior without increased costs for software or hardware such that a decoupling of mutually blocking tasks and/or threads occurs in real time systems.

Systems, methods and computer program products for controlling and visualizing processes

A method, in particular for monitoring, controlling and adjusting a process, wherein a signal processing instruction is synthesized on a computer-assisted user interface by arranging and connecting icons ( ), and generated by the computer from base modules containing individual instructions, one base module being allocated to each icon ( ), and the individual instructions of the selected base modules being linked to one another according to the graphic integration of the symbols ( ) for transmitting and/or processing data.

Method for process monitoring, control, and adjustment

A method for operating an eddy current sensor ( ) with a measuring coil ( ) and an evaluation circuit ( ) for determining material or geometric parameters of a test object ( ), in which the test object ( ) is arranged at a distance (d) from the measuring coil ( ). The impedance of the measuring coil ( ) is evaluated, while the measuring coil ( ) is being supplied with an alternating voltage of a predetermined frequency, and the evaluation circuit ( ) determines the material and geometric parameters of the test object ( ) based on the impedance of the measuring coil ( ). The impedance of the measuring coil ( ) is determined at an alternating voltage of a first frequency, and the impedance of the measuring coil ( ) is determined at an alternating voltage of a second frequency, and the evaluation circuit ( ) computes the material and geometric parameters of the test object ( ) on the basis of the impedances of the measuring coil ( ) at the first and the second frequencies. An eddy current sensor ( ) is also disclosed, which can be used with advantage in conjunction with the method.

Eddy current sensor for analyzing a test object and method of operating same

An eddy current sensor (,) has at least one measuring coil (,) that can be supplied with an alternating current, and an evaluation circuit (,). The eddy current sensor allows the temperature influences on the impedance of the measuring coil to be reliably compensated with a simple design and an evaluation circuit. For this purpose, the eddy current sensor has a compensating coil (,) which can also be supplied with an alternating current and which is arranged closely to the measuring coil, i.e. in thermal contact therewith, in such a way that the electric fields of compensating coil (,) and measuring coil (,) are orthogonal to each other. More particularly, the measuring coil (,) is in an annular form and the compensating coil (,) is wound around the measuring coil in the form of a torus.

The invention relates to the correction of an error-prone measuring signal of a pair of scanning rollers. The measuring signal is influenced by the circularity error of the pair of scanning rollers and/or by the eccentric mounting of the pair of scanning rollers. The pair of scanning rollers is used to measure the thickness of a fiber fleece or fiber sliver on a pre-spinning machine in the textile industry. The occurrence of a periodic error value in the measuring signal due to circularity error and/or eccentricity of the pair of scanning rollers is detected. The error value is stored in a position-related manner for one revolution of the scanning rollers and the stored error value is used in the operation of the scanning rollers within the cycles of rotation for the correction of the current, position-synchronous measuring signals.

Correction of a measuring signal obtained from a pair of scanning

A sensor arrangement and a method of acquiring properties of the surface layer (3) of a metallic target (2), which allow a nondestructive and substantially distance-independent measurement to be performed, with the requirements to be met by the sensor positioning being minimal. The sensor arrangement (1) comprises a combination of at least one eddy-current sensor (5) with at least one displacement measuring sensor (6), the depth of penetration of the eddy currents generated by the eddy-current sensor (5) corresponding to at least twice the thickness of the surface layer (3), and the displacement measuring sensor (6) serving to determine the distance of the sensor arrangement (1) from the target surface (4). The measuring signals of the eddy-current sensor (5) and the displacement measuring sensor (6) are evaluated on the basis of a hypothetical depth of penetration of the eddy currents, which is to be determined as a function of the frequency of the eddy currents and of the conductivity and permeability of the base material (8) of target (2).
