Abstract: A lamellae drive system includes a lamella moveably coupled to a carrier. The lamella includes a length extending parallel to a direction of motion of the lamella, and one or more groups of oscillating projections along at least a portion of the length of the lamella. A direction of oscillation of the oscillating projections is parallel to the direction of motion of the lamella, and the oscillating projections include opposing sloped surfaces oriented perpendicular to the direction of oscillation. The lamellae drive system includes two or more actuators. Each of the two or more actuators has an extendable dimension. The actuators are configured to drive the lamella by applying force to particular sloped surfaces of the one or more oscillating projections, with the force of the two or more actuators being applied out of phase with each other.

Abstract: A position control system includes contactless sensors and a controller. The sensors generate sensing signals indicating sensed movement of multiple parts configured to travel along multiple axes, and transmit the sensing signals to the controller, which includes a processor and associated memory. The controller receives, from a first sensor, a first sensing signal indicating sensed movement of parts in a first subset, and receives from a second sensor a second sensing signal indicating sensed movement of parts in a second subset. The two subsets include at least one part in common. A first sensed position of the common part(s) is determined based on the first sensing signal. A second sensed position of the common part(s) is determined based on the second sensing signal. A control signal configured to control movement of the common part(s) is generated based on the first sensed position and the second sensed position.

The safety apparatus comprises a controller configured to control a movement of at least a component of the medical apparatus by an operator, wherein the controller includes a dead man's device configured to output dead man's information as a function of a state of the dead man's device; an operating sensor configured to output operating information as a function of an operation of the controller by the operator; and an evaluator configured to verify an enablement of a motion control command based on the dead man's information and the operating information.

Abstract: In a method for operation of a docking arrangement, position information is determined that describes a position of the patient table, including detecting, sensor data corresponding to: the position of the patient table relative to the docking arrangement, and/or to an environment feature describing a movement trajectory to the docking arrangement. The method may further include performing, in response to a switchover condition indicative of a handover situation and a purely manual operation of the patient table by an operator, a switch into an assistance operating mode of the docking arrangement. In the assistance operating mode, at least one guidance measure may be determined for the patient table and a functional component of the patient table may be controlled to assist the operator.

Abstract: A method for assembling a steam generator includes parallel assembly of the boiler framework and preassembly of assembly modules, and hoisting of the assembly modules into the boiler framework. The outer roof section of the boiler framework roof is then assembled. The inner roof section and the internal components are assembled simultaneously with assembly of the boiler wall in the upper section of the steam generator. The segments of the external support pipes are mounted into the assembly modules and subsequently connected at their module joints the external support pipes are mounted in the final position in the outer roof section. The buckstays and the header tie bars are mounted headers to the boiler wall or to the external support pipes. The auxiliary steel structure of the assembly modules the suspension equipment of the curtain walls are dismantled.

Abstract: The present invention relates to a chemical process for modifying inorganic and organic substrates with thin polymer films that are grafted to a substrate. The preferred composition includes a dimethylamino terminated precursor that is deposited as a self-assembled monolayer onto a gold or silicon oxide, or other substrate. The polymerization is then initiated by irradiation with UV light in the presence of monomer and an optional photosensitizer.

Abstract: A method for measuring fault locations in high frequency cables and lines. A signal with the frequency f0 and a level a0 is emitted from the source. This signal is split up in the splitter and is routed to the same parts in the test piece (DUT=device under test) and to a sink. The signals of the source and the returning wave of the DUT are added, whereby the result of this addition is a signal with the frequency f0 and an amplitude a1. The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded. An inverse Fourier transformation transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram can thereby be located.

Abstract: L-Menthol is prepared from D,L-menthyl derivatives by enantioselective enzymatic cleavage.

The value of the frequency f0 is changed, and the amplitude of the newly generated sum signal is, in turn, recorded, whereby this is repeatedly carried out in an appropriate frequency domain (Span). An inverse Fourier transformation is applied to the measured values and transforms the signals from the frequency domain into the time domain. The transition point, which appears as the defined peak in the time diagram, can, as a result, be found located while taking the shortening factor into account.
