For smoothing of the modulated reference signal an amplitude limiter 11 and a band pass filter 15 are connected between the reference oscillator 5 and the HF-transmitting component 1.

Abstract: An acceleration sensor includes a deflectable pressure measuring diaphragm and a counter-structure, which is deflectable as against the pressure measuring diaphragm. The acceleration sensor includes a detection means for detecting a deflection of the pressure measuring diaphragm as against the counter-structure. Further, a test mass is connected to the pressure measuring diaphragm or the counter-structure in order to be deflected from an idle position depending on an acceleration applied. The deflection of the test mass results in a change of the distance between the pressure measuring diaphragm and the counter-structure, which is detectable by the detection means.

Abstract: A field-effect-controllable semiconductor component has at least one source zone and at least one drain zone of a first conductivity type, and at least one body zone of a second conductivity type. The body zone is provided between the source zone and the drain zone. In each case at least a first and a second region of the second conductivity type are provided in a channel zone.

The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.
