Publication number: 20240074321Abstract: A dielectric transducer for use in a sensor, actuator or generator comprising a plurality of layers of transducer foils, wherein an electrically contactable and conductive layer forming an electrode layer is applied to at least one side of each transducer foil. Expediently, at least two contact elements are provided, each of which is arranged at least partially in a recess or in a through-channel and extends over at least one layer of transducer foils, adjacent electrode layers being electrically conductively connected to different contact elements. Since adjacent electrode layers are connected to different contact elements, intended use is possible, and bringing together several contact lines is advantageously not necessary. Furthermore, the invention relates to a method for producing a multilayer dielectric transducer for use in a sensor, an actuator or a generator, as well as an actuator, a sensor or a generator.Type: ApplicationFiled: October 13, 2020Publication date: February 29, 2024Inventors: Steffen Hau, Stephan Lenz, Philipp Linnebach, Dennis Meier, Stefan Seelecke

Publication number: 20230375987Abstract: The invention relates to a method for operating a process system, in which method one or more actuators in the process system are set by means of one or more manipulated variable values specified by means of a control process, whereby one or more operating parameters of the process system are influenced. The control process is a self-optimizing control process which comprises the use of model-based deep reinforcement learning and the consideration of a cost function. One or more components of the process system are represented in a model by means of neural network, which model is used in the model-based deep reinforcement learning. The present invention also relates to a corresponding process system and to a method for converting a process system.Type: ApplicationFiled: September 29, 2021Publication date: November 23, 2023Inventors: Gerhard ZAPP, Stefan LENZ, Nicolas BLUM
