Abstract: An aircraft fuselage is configured to receive two tanks designed to contain liquid hydrogen. The fuselage includes a first section for a cockpit, a second section for a passenger cabin and a third section (T3) distinct from the first section (T1) and from the second section (T2). The third section (T3) includes two housings each to house a tank. The two housings are arranged symmetrically with respect to a vertical plane of symmetry (P1). This arrangement of the tanks in a section distinct from the other sections allows them to be located as close as possible to the motors that they have to supply.

Abstract: A method for assigning a smoke detector (2) to be registered to a user profile (11) of a smoke detector management system (1), comprising the steps: establishing a data connection between the smoke detector (2) and a server (3) and transmitting first identification data (6) of the smoke detector (2) to the server (3); establishing a data connection between a mobile device (4) and the server (3); logging into the user profile (11) by means of the mobile device (4) using the user identification data (5); transmitting second identification data (7) of the smoke detector (2) to be registered to the mobile device (4); transmitting the second identification data (7) and/or the user identification data (5) to the server (3) by means of the mobile device (4); and identifying the smoke detector (2) by means of the first and/or second identification data (6; 7) and assigning the smoke detector (2) to the logged in user profile (11) or the user profile (11) corresponding to the user identification data (5).

Abstract: An electrical pulse fed into an electrical cable, e.g. a power transmission or distribution cable buried underground, produces an acoustic signal, e.g. an arc-over or discharge noise, at a fault in the cable. This acoustic signal is detected and used to locate the fault. But the acoustic signal has interference noise superimposed on it, which makes it difficult to identify the acoustic signal in the noise-burdened received signal, and thus also makes it difficult or impossible to accurately locate the fault. To minimize or avoid the influence of interference noises, the relevant acoustic signal is identified in the received signal by comparing the received signal with predetermined sample data, such as signal patterns, characteristics or characteristic sets.

Abstract: A device for assessing a quality class of an object to be tested includes a unit for detecting a test signal from the object to be tested. Furthermore, the device for assessing includes a unit for providing a stochastic Markov model including states and transitions between states on the basis of reference measurements of objects of known quality classes, and a unit for evaluating the test signal using the stochastic Markov model. In addition, the device for assessing includes a unit for associating the object to be tested with a quality class based on the evaluation of the test signal. Such a device has the advantage to be able to perform a more precise association of an object to be tested with a quality class as compared to prior art.
