Abstract: A process embeds functional fibers in a workpiece during selective laser sintering. In a process variant, parts of a powder layer are sintered before the insertion process, for example using a laser beam. A heating device then subsequently re-melts the already melted workpiece parts. Through a channel in the heating device, the functional fiber is fed to the melt or melt-like mass by means of a feed device and inserted into the melt or melt-like mass at the insertion point. Due to the movement of the heating device, the completely or partially melted area moves away from the heating element and is heated less, causing it to cool and solidify comprising the already inserted functional fiber. This variant can also be used for inserting fibers into objects created, for example, by injection molding or extruder-based 3D printing or other additive manufacturing processes.

Abstract: A method for identifying bus nodes in a bus system makes it possible to be able to operate bus slaves of two different types in mixed systems. The detection of which bus slave has not yet been allocated an address in an addressing phase is carried out differently depending on a type of the bus slave. In all cases, however, the bus slave connected to the bus line farthest away from the bus master is identified as that bus slave to which an address is to be allocated.

Abstract: Method and sensor system for measuring the transmission properties of a first transmission path based on feedback compensation between a first transmitter and a receiver, a compensation signal of a compensation transmitter being received in a superimposed manner in the receiver in addition to the emitted transmission signal of the first transmitter. A supply signal for the first transmitter and a receiver output signal each form a vector in a pre-Hilbert space. A Hilbert projection is performed between the receiver output signal and the supply signal so that a projection image signal is generated. An output signal is formed from the projection image signal. A pre-signal is generated by an inverse transformation of the output signal with the supply signal. A compensation signal for supplying the compensation transmitter is generated from the pre-signal formed in order to achieve feedback control of the receiver output signal.
