The invention relates to a coupling for a fluid line, wherein an oscillating circuit () is present for detecting a properly closed position of an inserted part (). A tuning device () is further provided, by means of which the resonant frequency of the oscillating circuit () can be influenced such that the resonant frequency corresponds to a characteristic closure frequency only in the closed position of the insertion part (). The proper arrangement of the insertion part () in the closed position can thereby be detected without contact.

Coupling for a fluid line

A time base including a resonator () and an integrated electronic circuit () for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an integrated micromechanical ring resonator supported above a substrate () and adapted to oscillate around an axis of rotation (O) substantially perpendicular to the substrate. The ring resonator includes a free-standing oscillating structure having a plurality of thermally compensating members () which are adapted to alter a mass moment of inertia of the free-standing oscillating structure as a function of temperature so as to compensate for the effect of temperature on the resonant frequency of the ring resonator.

Temperature compensation mechanism for a micromechanical ring resonator

A time base including a resonator () and an integrated electronic circuit () for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an integrated micromechanical ring resonator supported above a substrate () and adapted to oscillate in a first oscillation mode. The ring resonator includes a free-standing oscillating structure (). Electrodes () are positioned under the free-standing oscillating structure in such a way as to drive and sense a second oscillation mode in a plane substantially perpendicular to the substrate and having a resonant frequency which is different from the resonant frequency of the first oscillation mode, a frequency difference between the resonant frequencies of both oscillation modes being used for compensating for the effect of temperature on the frequency of the signal produced by the time base.
