  • Patent number: 12590489
    Abstract: The present invention relates to a window (2) or a door, comprising: ?(a) a frame or casing; ?(b) at least one sash (3) formed of portions of a hollow-chamber profiled element (4); ?(c) a planar element (11), which is accommodated in the sash (3), the planar element comprising a functional element (13), the light transmission properties of which can be varied at least in some regions when a voltage is applied; and ?(d) a control element (12; 12?), which is designed to control the functional element (11); wherein according to the invention the window or the door is characterized in that the control element (12; 12?) is of a multi-part design and at least one constituent part (12) of the control element (12; 12?) is at least partly accommodated in a hollow chamber (5) of the sash (3). The present invention also relates to a building wall (100) having at least one opening in which a window (2) or door of this type is accommodated.

  • Publication number: 20240030661
    Abstract: In order to manufacture an assembly consisting of a plastic tube portion having at least one tube-wire insert and a terminal connector, an electrical conducting component group is first prefabricated. Conducting components of the conducting component group provide an electrical connection with the at least one tube-wire insert, in the assembled state. A conducting component configuration is separated from the prefabricated conducting component group. The conducting component configuration is electrically contacted with the at least one tube-wire insert. The terminal connector is connected to the plastic tube portion. This results in an assembly manufacturing method which is suitable for mass production. The conducting component group is part of a multi-lead frame which has a plurality of different, selectable conducting component configurations that can be specified by selecting appropriate conducting components depending on the electrical contacting requirements.

  • Publication number: 20230302247
    Abstract: An assembly for a patient ventilation system has a respiratory air hose section for guiding ventilation air from a ventilation source to a patient. A connector, connected to the respiratory air hose section, is used to connect the respiratory air hose section to a further component of the patient ventilation system guiding ventilation air. An air guiding connector component of the connector forms an integral component with the respiratory air hose section. The connector has a sensor receptacle for inserting a temperature sensor into the air guiding connector component. The temperature sensor is used to measure a temperature of the ventilation air. A temperature sensor device to be plugged into the sensor receptacle of the assembly has a support body, the temperature sensor protruding beyond the support body, and a handle section to grasp a section of the support body facing away from the temperature sensor.

  • Publication number: 20230302242
    Abstract: For the production of an assembly for a patient ventilation system, at least one conducting connection is first prepared between contact pins of a component receptacle of a connector for the insertion of at least one electronic component and sheath wires which are guided along a tube sheath of a breathing air tube portion of the assembly. This prepared conducting connection is overmolded to form an inner conduction carrier housing sleeve of the connector. The conducting connection is connected to the sheath wires and the inner conduction carrier housing sleeve is overmolded to form an outer connector housing of the connector in which the component receptacle is implemented. This results in an assembly manufacturing process that is suitable for mass production.
