摘要： An emergency lighting element includes a planar, electrically operable radiation source for planar emission of electromagnetic radiation at a front side of the radiation source; and a long-afterglow layer over a whole area on the front side of the radiation source. A penetration depth into the long-afterglow layer for radiation emitted by the radiation source corresponds at least to a thickness of the long-afterglow layer. The long-afterglow layer comprises phosphorescent material, an absorption spectrum of the long-afterglow layer at least partly overlaps an emission spectrum of the radiation source and an emission spectrum of the long-afterglow layer lies substantially in a visible range.

摘要： A method uses a flexible endoscope to inspect one or more hard-to-reach components of a gas turbine. The flexible endoscope has at least one image capture unit, which is configured to capture visual image information and associated 3D data, and which is located at a free end of the flexible endoscope. The method includes: introducing the flexible endoscope through an inspection opening; capturing the visual image information and the associated 3D data by the at least one image capture unit; comparing the captured 3D data to a 3D model of a component to be examined, and based on the comparison, ascertaining a relative pose of the at least one image capture unit in relation to the component; and texturing the 3D model with the visual image information captured by the at least one image capture unit, in accordance with the ascertained relative pose of the image capture unit.

摘要： A supplementary function module is for vehicles for the supplementation of a function module supplied with electrical power via a power supply bus. The supplementary function module is configured to be supplied with electrical power via the power supply bus. The supplementary function module has a controller configured to detect a voltage in the power supply bus, and to deactivate the supplementary function module based upon a first predefined voltage variation being detected.

摘要： An escape path marking for an aircraft includes a lighting element, which luminesces in a dark environment, and which emits an emitted light which exits at an outer side of the escape path marking. A transparent protective element is arranged between the lighting element and the outer side of the escape path marking. A planar grid element, which comprises regularly alternating pure-color transparent and opaque regions, is arranged between the lighting element and the outer side of the escape path marking. A transparent pigmented element is formed and arranged between lighting element and the outer side of the escape path marking such that in an event of external illumination according to at least one predefined illumination scenario, a predefined first color tone results on the outer side of the escape path marking at the transparent regions of the grid element.

摘要： An arrangement provides addressing for a plurality of equipment. Each piece of the equipment is non-varyingly logically linked to a corresponding transceiver having a unique identifier and a plurality of transceiver antennae with non-identically oriented antenna lobes. Each corresponding transceiver is configured to transmit a signal having the unique identifier associated with the transceiver via each of the transceiver antennae individually and to receive any signal of a neighboring transceiver attributing it to the actually receiving transceiver antennae in order to determine pattern information pairs. A central instance is configured to collect the pattern information pairs from the transceiver transceivers and to compare the pattern information pairs with a stored pattern of the equipment to identify each transceivers' position in the stored pattern.

摘要： A method assess the quality of varnished wood surfaces. The method includes the following steps: a) creating a brightness map of the surface, b) creating a curvature map of the surface, c) ascertaining a cross-correlation of brightness map and curvature map, and d) evaluating the result of the cross-correlation to ascertain the proportion of the irregularities of the surface to be attributed to varnish flaws.

摘要： A method cleans surfaces in an internal volume of an aircraft component through which a medium flows. The method includes: connecting the internal volume to be cleaned to a steam generator; generating a cleaning steam having a predetermined vapour pressure and temperature by the steam generator; applying the cleaning steam to the surfaces to be cleaned in the internal volume; maintaining the vapour pressure and the temperature within the internal volume for the duration of a predetermined condensation time; generating a pressure drop in the internal volume of the aircraft component, in order to vaporise the portion of the cleaning steam that condensed during the condensation time; and removing the cleaning steam from the internal volume via a discharge device.

摘要： A device that equalizes an aircraft pressure difference has a separating wall, fixable to the aircraft, and a decompression valve. The wall is for fluidically separating first and second spaces, and has a flow opening that fluidically connects the spaces. The valve closes the flow opening. A securing element on the valve or wall enables a release of the valve when a pressure gradient between the spaces is exceeded, such that there is a fluidic connection between the spaces. The receiving element on the wall or valve is connected to the receiving element. The securing element has a rotary element and fixing elements. The rotary element is rotatably mounted about a rotational shaft. The rotary element is receivable in the receiving element. The fixing elements non-rotatably fix the rotary element beneath the predetermined pressure gradient. At least one of the fixing elements is a spring.
