  • Publication number: 20240074321
    Abstract: 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.

  • Publication number: 20230375987
    Abstract: 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.

  • Patent number: 11695173
    Abstract: A battery housing arrangement, in particular a battery housing assembly of a vehicle traction battery which can be temperature-controlled by a fluid, comprises a battery housing which encloses an interior space for receiving battery cells, and a heat transmission device which has an inlet tube, an outlet tube and a heat exchanger element arranged fluidically therebetween. The fluid is able to flow through the heat transmission device from the inlet tube via the heat exchanger element to the outlet tube. The heat exchanger element can be accommodated in the battery housing. The battery housing has at least one through-opening for feeding through the inlet tube and the outlet tube, and the battery housing has at least one closure element which is inserted into the at least one through-opening and forms a closure between the inlet tube and/or the outlet tube and the at least one through-opening.

  • Patent number: 11464293
    Abstract: In a method for adapting a thermally deformable item of clothing to a body part, the item is at least partially heated and brought into contact with an abutment region and the appropriate body part. The item of clothing has a side which, in the use position, is directed towards the body and a side which, in the use position, is directed away from the body. At least one pressure-exerting unit subjects that side of the item of clothing which is directed away from the body, at least in part, to a shaping pressure such that the at least partially heated item of clothing is adapted, at least in part, to the shape of the part of the body. The item of clothing is at least partially cooled by a cooling unit such that it is stabilized in the shape adapted to the part of the body.
