Abstract: A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and are connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and are electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, are in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.

Abstract: Disclosed herein are embodiments of an Al—Ce—Ni alloy for use in additive manufacturing. The disclosed alloy embodiments provide fabricated objects, such as bulk components, comprising a heterogeneous microstructure and having good mechanical properties even when exposed to conditions used during the additive manufacturing process. Methods for making and using alloy embodiments also are disclosed herein.

Abstract: Methods and systems for authenticating electronic devices via multi tone analysis. A method for authenticating a device under test (DUT) of a type of DUT includes imparting voltage tones to the DUT. The voltage tones are proximate a frequency of interest that is associated with the type of DUT. Using a measurement response of the DUT to the voltage tones, an electronic signature of the DUT is determined. The DUT is determined to be authentic when the electronic signature of the DUT substantially matches an electronic signature of an authority DUT of the type of DUT.

Abstract: A chord and/or note assist assembly includes a chord and/or note forming aid having a plurality of multi-position string engaging assemblies that engage strings of a guitar in a controlled manner so as to define chords associated with playing a guitar and an extension device having a plurality of multi-position string engaging assemblies that engage strings of a guitar in a controlled manner so as to define chords associated with playing a guitar. An electronic microprocessor circuit board is electrically linked to a solid-state memory to control the plurality of multi-position string engaging assemblies of both the chord and/or note forming aid and the extension device.

Abstract: A vehicle seat, in particular for utility vehicles, is provided with a seat part, a backrest and a lower part, in relation to which an upper part carrying the seat part and the backrest is resiliently mounted, the seat part being rotatably mounted in relation to the upper part by means of a rotary device about a rotational axis, which extends in the height direction of the vehicle seat, for a rotary movement and being resiliently mounted for a horizontal spring movement by means of a horizontal spring device in at least one direction running perpendicularly to the rotational axis, preferably the transverse direction of the vehicle seat, wherein both the rotary device and the horizontal spring device can be locked and unlocked at the same time with respect to the movements carried out with them by means of a common switching element.

Abstract: Mobile network services are performed at the edge of a mobile data network in a way that is transparent to most of the existing equipment in the mobile data network. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation, and performs one or more mobile network services at the edge of the mobile data network based on the broken out data. A second service mechanism in the core network receives data monitored during attach and Packet Data Protocol (PDP) context activation, and establishes sessions with components in the mobile data network that support charging and policy control for sessions broken out by the first service mechanism.
