Abstract: An integrated chip-based communication system is described. The integrated chip-based communication system includes a plurality of source ports and destination ports; and a crossbar or an interconnect. In an embodiment, the crossbar or the interconnect is configured, based upon an address matrix of an address header of a data packet received from one of the source ports, to ascertain one or more destination ports as receivers of the data packet; to transmit the data packet to the ascertained receivers; and to ascertain a readiness to receive of at least one of the receivers and design the data transfer as a function of the ascertained readiness to receive. A medical imaging facility is also described. Furthermore, a data transfer method for transferring data packets is described.

Abstract: A sound insulator for a motor vehicle passenger compartment is disclosed. The aim of the invention is to develop a sound insulator which makes it possible to obtain an improved damping effect within a frequency range less than 300 Hz. In that respect, the invention relates to a sound insulator for a motor vehicle passenger compartment, which comprises an air cushion consisting of a dampingly active envelope which is made of an elastic material and disposed between a sound-generating component and the compartment internal space. The invention provides for a sound damping layer (25) which matches the shape of said component (13), acts as a spring material system and is covered on the compartment side by a heavyweight film (26), thereby forming the first shell of the air cushion (29).

Abstract: In the single-indexing method, the blades are positioned in a circle on a cutter head, so that all of the blades run through a tooth space to be produced during cutting of a bevel gear. The workpiece is then rotated by one pitch and the continuously rotating cutter head may then cut the next tooth space. Since the blades do not all have their intended shapes and positions, different structures arise on the tooth flanks, which lead to deviations in the pitch measurement. In order to avoid this, a face-milling method is suggested in which the cutter head gets the same angular position around its axis in relation to the tooth space to be produced as for the preceding space. This has the result that all tooth spaces are not more precise overall, but their surface structures are identical and the pitch measurement is thus not falsified.

Abstract: In a method and apparatus for machining spiral bevel gears a rotationally symmetric tool is driven about its axis of rotation as it is moved, along with a workpiece, into a respective initial starting position. The workpiece is rotated about one tooth index, and a complete tooth space is processed via a generating method to a preset generating depth. The tool and workpiece each reach first end roll positions and are then moved into respective second starting positions near the previously reached end roll position. The workpiece is once again rotated about a tooth index and another complete tooth space is generated using a roll direction reversed relative to the initial tooth generating process. The tool and workpiece reach a second end roll position near the first start position and these steps are repeated until all the tooth spaces of the workpiece have been processed.
