Abstract: A method for operating a door actuator of a door system, with at least one movable door leaf and a control device to control a drive of the door leaf, and with a sensor unit with which data of at least one object is recorded in a detection region in front of the door system and at least one item of information about the object is transmitted to the control device. The method includes at least the following steps in the order listed: a) recording object data of the object, b) processing the recorded object data, c) evaluating the processed object data, d) dividing the detection region into first and second partial regions, e) identifying a desire to enter of the object depending on the partial region in which the object data was recorded, and f) opening the door leaf only in the case of an identified desire to enter.

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.

Abstract: A door system with a door actuator, includes at least one door leaf, and a sensor unit configured and connected to a control unit of the door system, with the approach of an object to the door system within a detection region being detected by the sensor unit, in particular designed as a radar sensor or as a camera. The method includes at least the following steps: determining for the first time at least one first object position of the object within the detection region, determining for the second time at least one subsequent second object position of the object within the detection region, calculating an object vector based on the determined first and second object positions and opening the at least one door leaf depending on the properties of the calculated object vector. A door actuator for carrying out the method and a computer program product are also related.

Abstract: A door actuator for a door system with at least one door leaf, with a sensor unit being is configured and connected to a control unit of the door system, with the approach of at least one object to the door system within a detection region being detectable by the sensor unit, with the control unit configured to provide to the sensor unit deactivation data for deactivating the detection of the at least one object in at least one defined partial region of the detection region and/or to hide, delete and/or filter out object data, detected by means of the sensor unit, of at least one detected object in a defined partial region of the detection region. A door system for carrying out such a method and a computer program product are also related.

Abstract: A polysiloxane includes first, second and third repeating units linked together in any order, wherein the first repeating units are based on first precursors selected from divinyldialkoxysilanes, substituted and unsubstituted vinyldialkoxysilanes, and monosubstituted and unsubstituted dialkoxysilanes, the substituted vinyldialkoxysilanes and the monosubstituted dialkoxysilanes each include substituents independently of one another, selected from substituted and unsubstituted alkyl groups and substituted and unsubstituted aryl groups, the second repeating units are based on second precursors selected from dialkoxysilanes including a substituent selected from substituted and unsubstituted alkyl and substituted and unsubstituted aryl groups, and a substituent selected from substituted and unsubstituted polycyclic aromatic hydrocarbon groups, and the third repeating units are based on third precursors selected from substituted dialkoxysilanes and substituted disilanols each including two substituents independentl
