Abstract: The present invention relates to a silencer device for a fluid line which comprises a resonator arrangement which comprises a first resonator tube comprising a first resonator chamber designed for a ?/4 damping of at least one sound wavelength, wherein the first resonator tube comprises a first longitudinal direction, two end walls facing each other in the first longitudinal direction and a first side wall extending between the end walls, and wherein the first resonator chamber is formed between the first side wall and the end walls of the first resonator tube.

Abstract: A device, a system and a method for detecting an irregularity in a structure of an aircraft are proposed. The device includes a resonant circuit with a resonance frequency and a probe for tuning the resonance frequency of the resonant circuit. The resonant circuit and the probe are operatively connected in such a way that the probe changes the resonance frequency of the resonant circuit if the structure changes due to a formation of an irregularity.

Abstract: A pressure cooker with a handle with an operating element, wherein the operating element comprises a rotating shaft. Also, a pressure cooker with an operating element with which pressure from the pressure cooker can be relieved through an aperture, wherein means are provided with which the pressure can be relieved with at least two specified different pressure relief rates or with at least one specified pressure relief rate and with a pressure relief rate which can be set to greater values than the specified value. Also, a pressure cooker with an operating element for opening and closing an aperture of the pressure cooker, wherein a second operable aperture of the pressure cooker is provided, as well as a pressure cooker with a pressure acquisition device having a mechanical part with at least one part, movable by the pressure, and an electronic part, which can acquire the position of the movable part in order to determine the pressure.

Abstract: A stress/strain measuring sensor for the continuous monitoring of stress/strain conditions, especially in screwed bolts, along with a corresponding measuring process is disclosed. An arrangement, and a corresponding method, are provided that are uncomplicated and easy to implement, and enable a continuous monitoring of stress/strain conditions. This is attained using a sensor (1) that comprises a first inductor (3) and at least one additional element (2), which comprises at least one pressure-dependent first impedance (5) or a second impedance (5?) and a second inductor (3?), wherein the second impedance (5?) and/or the second inductor (3?) are pressure-dependent, so that when the amount of pressure applied to the element (2) changes, the resonant frequency of an electromagnetic resonating circuit (3, 5; 3?, 5?) that is formed by impedance (5, 5?) and inductor (3, 3?) changes.

Abstract: A system for controlling a motor vehicle includes a first device for determining control data required for controlling the motor vehicle. A second device monitors the first device. The first device determines second data on the basis of first data, pursuant to a test function. The second device determines third data on the basis of the first data, pursuant to the same test function. The first and/or the second device recognizes an error state relevant to safety, dependent upon a comparison between the second data and the third data.
