Abstract: A housing for receiving an electrically operated apparatus may include an inner housing part at least partially defining a housing interior. The inner housing part may include an inner passage opening. The housing may also include an outer housing part disposed on a side of the inner housing part facing away from the housing interior. The outer housing part may include an outer passage opening. The outer passage opening and the inner passage opening may at least partially define an acoustic duct for discharging airborne noise from the housing interior. The acoustic duct may be closed by a fluid-tight and airborne noise-permeable membrane. Further, the housing may include a porous member disposed within the acoustic duct configured to prevent an ignition breakthrough from the housing interior into an external environment outside of the outer housing part.

Abstract: A device assembly for accommodating an electrically operated device may include a housing made from a plastic, delimiting a housing interior space, and having a viewing window formed therein that may be closed by a window pane made of a transparent material. The device may include an electrically operated device arranged inside the housing interior space, on the outside of which at least one actuatable control element may be provided. An aperture may be formed in a housing wall in which an actuating element made from an elastic plastic may be arranged at least partially and may be operable by a user of the electrically operated device. The actuating element may be coupled mechanically to the control element such that the control element is operable from outside the housing. An inner housing part made from an elastic plastic may be arranged on an inner side of the housing wall.

Abstract: A rotor of a turbomachine. The rotor includes at least one blade (4, 6, 8) that has a blade leaf (20) and a blade root (54, 55, 58), and a rotor base body (2), in particular a disk (2), that has an outwardly open, circumferential groove (12) for receiving the blade root (54, 55, 58). The circumferential groove (12) and the blade root (54, 55, 58) are shaped in a way that allows the blade root (54, 55, 58) to be secured in the circumferential groove (12) by the rotation of the blade (4, 6, 8) about an axis (Ar, AT).

Abstract: A device arrangement may include an inner casing. The inner casing may include an inner casing base and an inner casing cover defining a cavity therebetween. The cavity may receive an electronic device. The inner casing base may have a first viewing window. A window pane may be composed of a transparent material and be attached to at least one of the electronic device and the inner casing. The window pane may at least partially seal the first viewing window. An outer casing may at least partially encase the inner casing. The inner casing may be mounted on the outer casing via a suspension/damping device.

Abstract: A device arrangement may include a casing surrounding a casing interior. The casing may include a viewing window which is sealed by a transparent window pane. An electronic device may be disposed in the casing interior and have a display. The display may be secured in a fixed position on the window pane. A suspension/damping device may support at least one of the window pane and the electronic device on the casing.

Abstract: A device arrangement for receiving an electronic device may include a casing enclosing at least partially a casing interior. A resilient partition wall may be disposed in the casing and divide the casing interior into a first sub-chamber and a second sub-chamber fluidically separated from the first sub-chamber. The first sub-chamber may be configured to receive the electronic device. The first sub-chamber may include a first gas at a pre-determined gas pressure and the second sub-chamber may include a second gas having a second gas pressure. A pressurizing device may be disposed in the casing interior and be configured to increase the pre-determined gas pressure of the first sub-chamber by a pre-determined amount in relation to the second gas pressure in the second sub-chamber. The second sub-chamber may communicate fluidically with a surrounding environment of the casing.

Abstract: An electronic circuit arrangement for use in an explosive area may include an electrical signal line, which connects an electrical input connector to an electrical output connector, and an electrical earth line, which can be or is electrically connected to the electrical signal line by at least one electrical earthing line. An inductive component and a semiconductor switch may be arranged in the at least one earthing line. The semiconductor switch may be switched between a closed state, in which the signal line is electrically connected via the at least one earthing line to the earth line, and an open state, in which this electrical connection is interrupted.

Abstract: Embodiments of a child-friendly analyte measurement system are provided for detecting at least one analyte in a bodily fluid. A measurement system comprises at least one measurement instrument for detecting the analyte in the bodily fluid.
