摘要： A gas-powered drive system has a drive which includes a first chamber and a second chamber which are separated from one another by a piston. One of the chambers is connected to a gas source to drive the work element and the other chamber is connected via an exhaust air throttle to a gas sink by means of a reversing valve to movement of the piston. A control valve is assigned to the driving chamber through which the driving chamber can be filled with gas from the gas source. The opening cross-section of the control valve is set as a function of a control pressure.

摘要： The invention describes an apparatus that implements efficient coupling between a photonic integrated circuit (PIC) and a second optical element such as a fiber or laser, while at the same time allowing for efficient polarization management and/or optical isolation. It enables the packaging of PICs with large single mode fiber counts and in- and out-coupling of light with arbitrary polarization. The apparatus comprises a glass interposer that contains at least one polarization selective element together with a pair of lenses transforming a beam profile between the 2nd optical element and a polarization selective coupler on the PIC. The invention also comprises a method for fabricating the apparatus based on a subassembly of building blocks that are manufactured using wafer-scale high-precision glass-molding and surface treatment(s) such as thin-film coating.

摘要： A method for measuring process parameters in liquid cultures in a plurality of microreactors of at least one microtiter plate includes continuously agitating the liquid cultures using an orbital agitator at least until the reaction is completed in all the microreactors. In order to allow process parameters also of such substances which themselves do not have any fluorescence activity to be measured with relatively low complexity and within a short time, 2D fluorescence spectra are recorded in a plurality of in particular different liquid cultures in the microreactors of agitated microplates. A device for carrying out the method is also disclosed.

摘要： The invention relates to a method for carrying out signal detection by means of magnetic particle imaging, in which method magnetic/magnetisable particles (4), arranged in the field-free region of a location-dependent magnetic field, in particular a gradient magnetic field, are magnetised by means of an excitation magnetic field that changes over time, and the harmonics (9, 15), generated by the particles (4), of the frequency of the excitation magnetic field are detected as a signal from the magnetic particles (4) by means of a receiver coil arrangement (1) which in particular surrounds the particles (4), wherein a signal-transmitting arrangement, which has an outer coil (10) and at least one inner coil (11; 16, 17) connected in series to said outer coil, is positioned within the receiver coil arrangement (1) around the particles (4), wherein the signal received from the particles (4) by the at least one inner coil (11; 16, 17) is transmitted to the outer coil (10) by current flow and is re-emitted by said outer coil, in particular as a result of which the signal (S) received directly from the particles (4) and the signal (S) received from the particles (4) indirectly by the outer coil (10) are superimposed at the receiver coil arrangement (1). The invention also relates to a signal-transmitting arrangement for a magnetic-particle-imaging scanner/spectrometer, comprising an outer coil (10) which in particular has a smaller diameter than the sample-receiving channel (2) of the scanner/spectrometer, and comprising at least one inner coil (11; 16, 17) which is arranged in the outer coil (10), preferably arranged coaxially therein, and in particular has greater diameter than a sample to be examined, wherein the outer coil (10) and the inner coil (11; 16, 17) are electrically connected in series. The invention also relates to a system comprising a magnetic-particle-imaging scanner and a signal-transmitting arrangement.
