Abstract: A method for controlling a synchronous, distributed emission of light. A luminous bracelet which is distributed to the audience of a concert is known from the prior art. The problem to be solved is increased integration of the visitors into an audio-visual performance without having to distribute a large number of special devices. The problem is solved by emitting synchronous, distributed light from a plurality of portable personal devices, especially smart devices, wherein setting up of each portable personal device is initiated by the respective portable personal device contacting a control system, particularly a radio network, and the synchronous, distributed emission of light by the plurality of portable personal devices is caused by transferring at least one first piece of information regarding timing and/or at least one second piece of information for color control of the emission of light is effected by the control system.

Abstract: The turbomachine comprises a casing (26), there being arranged in the casing an impeller (23) arranged on a driven shaft. The turbomachine has an inflow region (21) and an outflow region (22) and, in operation, is flowed through by a working medium. The working medium flows into the inflow region, along a front side (23a) formed on the impeller and subsequently out of the outflow region, there being a pressure drop at the front side between the inflow region and the outflow region. A pressure divider (9) is arranged on the rear side of the impeller, opposite the front side.

Abstract: A modular dental system, methods for controlling a modular dental tool, a dental system, a control module, and a treatment unit. In one embodiment, the modular dental system includes a modular dental system including a control module and a battery module.

Abstract: The invention relates to a device and a method for separating dirt particles from the working medium of a turbine (10). The turbine (10) comprises at least one rotor (11) which is arranged in a housing (17). A swirl generator (20) is provided that sets the working medium and the dirt particles in a spiral-shaped rotational movement along a principal axis (22) by means of the geometry of the swirl generator (20) and thereby separates the dirt particles from the working medium. The swirl generator (20) is designed in such a way that the working medium experiences a reversal of the speed component parallel to the principal axis (22) within the swirl generator (20).

Abstract: The invention relates to a steam turbine 5, in particular for utilizing the waste heat of an internal combustion engine, having at least one turbine housing, having a guide wheel 10 that has at least one nozzle, and having at least one rotor 6, wherein the nozzle is in the form of a duct 11 formed into the guide wheel 10. According to the invention, a steam turbine 5 is provided, the nozzles of which can be manufactured in a simple manner. This is achieved by virtue of the fact that the duct 11 has a constant width B and has a depth T that varies along the duct 11. In this way, the duct 11 can be produced by means of a single tool in a single working operation.

Abstract: A method for operating an expansion card of a computer is proposed, said computer having at least one slot for accommodating the expansion card, wherein there is stored in a memory area of the expansion card a first and a second configuration data record, one of which is assigned to a first and the other to a second signaling voltage, and wherein the configuration data records transmitted to a FPGA chip of the expansion card indicate to the FPGA chip whether a protection circuit is to be activated or deactivated. Suitable measures enable functional units of a PCI expansion card suitable for both a 3.3 V and a 5 V signaling voltage to be integrated in an FPGA together with a PCI controller, the expansion card being supplied or suppliable with an external voltage independently of a signaling voltage of a computer or basic system.
