Patent number: 11800627Abstract: A probe for measuring plasma parameters by means of active plasma resonance spectroscopy comprises an external coupling, a balun, an internal coupling, and a probe head. It is provided that the couplings, the balun, and the probe head are integrated in an electrically-insulating substrate cylinder, and the substrate cylinder has a layered structure made from multiple substrate layers along its rotational axis. In this way, a probe for measuring plasma parameters is provided which enables an improved measurement of the plasma parameters, wherein the plasma is influenced as little as possible during the measurement of the plasma parameters.Type: GrantFiled: June 25, 2019Date of Patent: October 24, 2023Assignee: RUHR-UNIVERSITÄT BOCHUMInventors: Dennis Pohle, Christian Schulz, Ilona Rolfes

Patent number: 11733658Abstract: The invention relates to a method for the two-position control of an actuator (1) on the basis of a binary sensor signal (y) of a sensor unit (2), which senses a process variable (P), which can be influenced by the actuator (1), in such a way that the sensor unit outputs a first sensor signal value (y1) when a first switching value (Sw1) is exceeded and a second sensor signal value (y0) when a second switching value (Sw1, Sw2) is fallen below, wherein: the actuator (1) is controlled with a manipulated variable (u), which assumes either a first control value (u1) or a second control value (u2); the first control value (u1) and the second control value (u2) are dynamically adapted during the operation of the actuator (1), in dependence on a fall time (t_fall) corresponding to the duration of the first sensor signal value (y1) and a rise time (t_rise) corresponding to the duration of the second sensor signal value (y0), in such a way that the first and second control values converge.Type: GrantFiled: June 11, 2019Date of Patent: August 22, 2023Assignee: RUHR-UNIVERSITAT BOCHUMInventors: Sebastian Leonow, Martin Moennigmann

Publication number: 20210039319Abstract: Beginning on a starting area on a surface of a digital model, a layered subdivision of the model takes place to produce a three-dimensional object. Positioning of the layers on the starting area is based on calculation of a distance field, which assigns to each point of the model volume a shortest distance within the volume to the nearest starting area. For each discrete point of a layer defined by a distance field an orientation of a processing head is determined. The surface normal of the layer is calculated or gradient vectors of the distance field are calculated, which show a direction of the steepest rise in distances for the discrete point. Shape and distribution of layers conform to the shape of the digital model. The sequence for the adaptive construction results from the assignment of the layers to distance values, beginning with a lowest distance value in ascending order.Type: ApplicationFiled: February 13, 2018Publication date: February 11, 2021Applicant: RUHR-UNIVERSITÄT BOCHUMInventors: Michael RIEGER, BENJAMIN JOHNEN, BERND KUHLENKÖTTER

Patent number: 9113543Abstract: The invention relates to a device and method for measuring the density of a plasma by determining an impulse response to a high-frequency signal coupled into a plasma. The density, electron temperature and/or collision frequency as a function of the impulse response can be determined. A probe having a probe head and a probe shaft can be introduced into the plasma, wherein the probe shaft is connected to a signal generator for electrically coupling a high-frequency signal into the probe head. The probe core is enclosed by the jacket and has at its surface mutually insulated electrode areas of opposite polarity. A balun is arranged at the transition between the probe head and an electrically unbalanced high-frequency signal feed to convert electrically unbalanced signals into balanced signals.Type: GrantFiled: October 6, 2011Date of Patent: August 18, 2015Assignee: RUHR-UNIVERSITÄT BOCHUMInventors: Ralf Peter Brinkmann, Jens Oberrath, Peter Awakowicz, Martin Lapke, Thomas Musch, Thomas Mussenbrock, Ilona Rolfes, Christian Schulz, Robert Storch, Tim Styrnoll, Christian Zietz
