    摘要： A safety helmet (100) includes an arched helmet shell (1), a bearing structure (3, 4.l, 4.r, 5, 6, 8, 10), an inner lining and a plurality of connection units. The inner lining comes into contact with the head of a user of the safety helmet. The bearing structure is attached on the inside to the helmet shell. Each connection unit is capable of detachably connecting the inner lining to the bearing structure. Each connection unit comprises a bearing structure-side component and an inner lining-side component. Each component is configured as exactly one connection type. A bearing structure-side component is connectable to an inner lining-side component if the two components are configured as the same connection type. The two components cannot otherwise be connected to one another or are incapable of establishing a connection between the bearing structure and the inner lining.

    摘要： A filter unit (100) is configured to filter out particles from a gas mixture flowing through filter unit (100). A process of manufacturing the filter unit (100) is also provided. A particle filter (1) is arranged in a housing (2, 4). The particle filter (1) has a larger end face (Sf.e), a smaller end face (Sf.a) and a lateral surface (M) between the two end faces (Sf.e, Sf.a). A circumferential gap (Sp) is formed between the lateral surface (M) and the housing (2, 4), which tapers towards the larger end face (Sf.e). To produce the filter unit (100), the particle filter (1) is inserted into a housing part (2), and a sealing compound is filled into the tapering gap (Sp). The sealing compound hardens and forms a sealing element (9).

    摘要： A process and arrangement automatically generate a floor plan of a building. A set of voxels in the form of polyhedrons is computationally generated and together fill the floor space. The edges of the polyhedron are parallel to the axes of a specified three-dimensional coordinate system. A camera (IR) is moved through the story and generates a sequence of images. The respective position and orientation of the camera (IR) while generating an image are measured. Characteristic key points (S1′, S2′, . . . ) are determined and positioned in the coordinate system. Free voxels (Vx, Vy), i.e. voxels inside a room, are determined. At least one cluster, including a topologically connected set of free voxels, is generated. An enveloping body is placed around each determined cluster. Each enveloping body describes the respective boundaries (W, F) of a room (R.x) of the story.

    摘要： A fire training facility, which simulates a fire onboard an electric vehicle. A dummy vehicle has the external dimensions of a real vehicle and has a dummy of a rechargeable battery and at least one dummy of a tire of the vehicle. The rechargeable battery dummy is positioned onboard the dummy vehicle in the same way as a rechargeable battery onboard a real vehicle. A smoke pot or fog pot generates fog, which is released from the rechargeable battery dummy. A flame generator of the rechargeable battery dummy generates flames, which are released from the rechargeable battery dummy. The dummy tire or each dummy tire is positioned onboard the dummy vehicle in the same way as the corresponding tire onboard a vehicle. A flame generator of the dummy tire generates flames, which are released from the dummy tire.

    摘要： A gas sensor (2) distinguishes between a target gas and a contaminant and includes a light source (8), a measurement volume (4), a detector (22), and an adaptable filter system (20) with a first optical filter and a second optical filter. The filter system switches between a first composite state, with both filters in a reference state, a second composite state, with the first filter in a first reference state and the second filter in a second measurement state, a third composite state with the first filter in a first measurement state and the second filter in a second reference state, and a fourth composite state, with both filters in a measurement state. The gas sensor detects a target gas and makes a determination as to a presence of the contaminant by comparing the respective detector signals, generated during at least three of the composite states, with each other.

    摘要： A housing (10) for a closed-circuit breathing apparatus (100) is provided for mounting respirator components (110) in an interior (40) thereof. The housing (10) includes a housing mount (20) and a housing cover (30) for covering the interior (40). The housing mount (20) has a first partial section (52) of at least one passage opening (50) for passage of a breathing tube (120) into the interior (40). The housing cover (30) has a second partial section (54) of this passage opening (50). The housing mount (20) and/or the housing cover (30) further have/has a fastening section (60) for the mechanical fastening to a counter-fastening section (122) of the breathing tube (120), which breathing tube (120) is guided through the passage opening (50).
