摘要:
A method is disclosed for operating a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, with a characteristic of the sensor arrangement being recorded in an initialization phase from measured values of the at least one measuring sensor and of the at least one reference sensor, and an alarm being given during continuous operation if the deviation from the characteristic lies outside a tolerance band. It is proposed to suspend the alarm dynamically so long as the changes in the measured value in the variation over time of the at least one measuring sensor or in the variation over time of the at least one reference sensor differ by more than a definable limit within a definable time interval.

A method is provided for producing windings for a dry-type transformer with in each case one winding for the low voltage (LV winding) and one for the high voltage (HV winding). The LV and HV windings are each electrically insulated from one another and have layers which are electrically insulated from one another by virtue of, initially, the winding for the low voltage being produced from electrically conductive wire or tape material and an insulating layer including resin-impregnated fibre material. Prior to the application of the HV winding, the maximum insulating thickness for the layer insulation and the number of fiber rovings corresponding to this insulating thickness can be determined, and each winding layer and the associated insulating layer can be produced simultaneously with a physical offset with respect to one another. To produce the winding, fiber polymer layers can be applied, as layers of insulation, simultaneously with the winding conductor between the individual winding layers of the winding, and the finished winding is subjected to a curing operation.

An integrated process tool monitoring system for semiconductor fabrication. Specifically, a process tool parameter auditing system, where a process tool user need not run a different verification system for each process tool type used and need not download parameters every time before a semiconductor device or material is to be processed by the process tool.
