Abstract: A motor vehicle has a self-supporting body which has a passenger compartment, with two longitudinal members, with two rear reinforcing struts which run in a V-shaped manner and are fastened at the front ends thereof to lateral longitudinal member portions of the two longitudinal members. The lateral longitudinal portions run below the passenger compartment. The two reinforcing struts are arranged at the rear ends thereof on a receiving component. The receiving component is a plastics/metal hybrid component which is composed of an open, shell-shaped metal component and of a fiber-reinforced reinforcing plastics component. The plastics component is integrated in the metal component and reinforces the metal component.

Abstract: A tray element is provided for a motor vehicle. The tray element can be arranged in a stowage region of the motor vehicle and has at least one receiving tray open at the top in the vertical direction of the motor vehicle for at least partially receiving at least one battery (14) of the motor vehicle. The tray element is designed as a die-cast component made of a light metal.

Abstract: A screwed assembly consists of at least one pre-punched, upper and an unpunched, lower component, an intermediate layer arranged in between, and a plurality of self-drilling fastening screws which are introduced via a pre-punch hole in the upper component and screwed to the unpunched component with the interposition of the intermediate layer. In order to effectively prevent in a simple manner any still uncured intermediate layer material from flowing out of the upper component surface when the fastening screws are screwed in, the pre-punches in the upper component are designed as blind holes which are closed by a thin-walled web.

Abstract: A system for scheduling, changing, and maintaining an outage schedule includes a data entry module adapted to allow a user to enter data pertaining to an outage, a pre-defined database containing transaction rules to define transaction flows, a processing module, and a display module. The processing module is adapted to process the data entered into the data entry module and the transaction rules provided in the pre-defined database. The display module receives processed data from the processing module, transforms the processed data into visual information representative of the processed data, and displays the visual information on a display of a computing device.

Abstract: A computer system that includes a storage medium. The storage medium stores a database. The database includes tables. Each table includes g at least one column and at least one row. The tables describe components of a hierarchy in which hierarchical relationships between components of the hierarchy are defined. The tables include a component table and component-specific tables. The component table is a self-referential table that describes the hierarchy. Each row of the component table is specific to a unique component. The components of the hierarchy encompass component types. Each column of component table is configured to be edited by a user through use of a worksheet. Each component-specific table encompasses only components of the hierarchy such that each component has a component type that is a specific component type.

Abstract: A frequency division, energy comparison, source detection signal processing system which decomposes a wide-band signal into a plurality of narrow frequency band components, generates the energy envelope of each of those narrow band components, determines the envelope correlation coefficients, and detects the presence of a source contributing to the wide-band signal from the correlation coefficients.

Abstract: A frequency division, energy comparison signal processing system for detecting the presence of, and separating the contributions from, sources that compose a wide-band sound signal, in which the system divides at least part of the wide-band sound signal into a number of discrete narrow frequency band components, generates the energy envelope of each of those components, normalizes the envelopes, multiplies each normalized envelope with each of the other normalized envelopes to obtain a plurality of envelope correlation coefficients for each frequency band, and then identifies from the correlation coefficients a sound source seed frequency band component and then, using the seed, identifies the remaining frequency components of a sound source.

Abstract: A frequency division, energy comparison processing system which decomposes a wide-band signal into a plurality of narrow frequency band components, generates the energy envelope of each of those narrow band components, and compares a function of each energy envelope with the same function of each of the other energy envelopes to obtain a pattern of the function comparisons indicative of at least one of the sources contributing to the wide-band signal.

Abstract: An apparatus for safeguarding a welding pool in mechanized welding in a constrained position, for example a vertical position, comprises sliding blocks pressed against the surfaces of the work pieces to be welded and supplying the welding current and the welding electrode and moving at the welding rate. The sliding blocks comprise two segments which are closely adjacent in the perpendicular center plane of the welding gap between the work pieces and are mutually movable. The sliding block segments are pressed in a yielding manner against the surface of each work piece and are individually and independently movable.
