Abstract: A system comprises a pedestal and a controller. The pedestal is arranged below a showerhead in a processing chamber and includes at least three electrodes to clamp a substrate to the pedestal during processing. The controller is configured to measure a pedestal-to-showerhead gap and at least one of a magnitude and a direction of a relative tilt between the pedestal and the showerhead by sensing impedances between the at least three electrodes and the showerhead.

Abstract: A method for controlling applications distributed between a vehicle and a cloud. A supervision of communication channels between the vehicle and the cloud is carried out. Based on the supervision, a control and adaptation of a component of the applications operated in the vehicle or of a component of the applications operated in the cloud are carried out.

Abstract: A rotor end-winding support for a high-speed electrical machine such as a turbogenerator in the form of an end bell which surrounds the end-winding and comprises two concentric rings. The inner ring made, for example, from a high-strength antimagnetic steel is shrunk into the rotor body and secured against axial displacement. The outer ring, made, for example, from a carbon-fibre-reinforced material or a nonmagnetic e.g. titanium alloy having a high ratio of strength to specific weight, is either shrunk onto the inner ring or expanded hydraulically to permit a slipover fit. The division of the end bell structure into a number of concentrically arranged components makes it possible to use combinations of materials, the respective component rings being allotted functions which correspond to their particular properties.

Abstract: An exciter current lead-through bolt which is passed through a radial bore in the rotor shaft of a dynamo-electric machine, especially a turbo-generator, and screwed into an exciter-current lead-in conductor bar which lies in a longitudinally extending bore within the shaft. The radially outer part of the lead-through bolt is mechanically and electrically connected with a terminal conductor bar leading to the exciter winding located on the rotor. In order to reinforce the lead-through bolt and minimize the danger of breakage, a radially inwardly directed resilient force is applied to the outer end of the bolt. Provision is also made for internal as well as external cooling of the through-bolt by air which is taken in by respective air pick-up devices located on the surface of the shaft.

Abstract: A brush holder structure for use in conjunction with transfer of current between a brush and a collector ring or commutator, respectively, on the rotor component of a dynamoelectric machine and which can be removed while the machine is in operation in order to renew worn-down brushes includes an electrically conductive support designed sectionally in L- or U-shaped form provided with a bore into which is screwed a combined mounting and plug-in device adapted to be removably inserted and interlocked with the brush rail structure of the electrical machine.
