Abstract: An rate-of-rotation sensor having a Coriolis element, which is arranged over a surface of a substrate, is described. The Coriolis element is induced to oscillate in parallel to a first axis. In response to a Coriolis force, the Coriolis element is deflected in a second axis, which is perpendicular to the first axis. A proof element is provided to prove the deflection.

Abstract: A yaw-rate sensor is proposed having a first and a second Coriolis element (100, 200) which are arranged side-by-side above a surface (1) of a substrate. The Coriolis elements (100, 200) are induced to oscillate parallel to a first axis. Due to a Coriolis force, the Coriolis elements (100, 200) are deflected in a second axis which is perpendicular to the first axis. The first and second Coriolis elements (100, 200) are coupled by a spring (52) which is designed to be yielding in the first and in the second axis. Thus, the frequencies of the oscillations in the two axes are developed differently for the in-phase and antiphase oscillation.

Abstract: A yaw-rate sensor is proposed having a first and a second Coriolis element (100, 200) which are arranged side-by-side above a surface (1) of a substrate. The Coriolis elements (100, 200) are induced to oscillate parallel to a first axis Y. Due to a Coriolis force, the Coriolis elements (100, 200) are deflected in a second axis X which is perpendicular to the first axis Y. The oscillations of the first and second Coriolis elements (100, 200) take place in phase opposition to each other on paths which, without the effect of a Coriolis force, are two straight lines parallel to each other.

Abstract: The invention concerns a process for affinity viscosimetry and a viscosimetric affinity sensor on the basis of sensitive liquids with analyte-dependent viscosity which are localized within a perfusable dialysis chamber and contain colloidal constituents which are cross-linked by affinity bonds. The viscosimetric affinity sensor according to this invention is characterized by the spatial or temporal separation of analyte diffusion from the measurement of the flow resistance for such sensitive liquid flowing through a capillary, needle-like body or other liquid conductor, which integrated combination of a dialysis chamber with viscosimeter enables a researcher to make measurements under lab conditions that provide spatial separation of the dialysis process from the rheological analysis, as done under test conditions where the maximum shear rate of sensitive liquid in the viscosity sensor is at least twice that shear rate of sensitive liquid experienced in the dialysis chamber.

Abstract: In a method for producing a pressure sensor, a ceramic plate is joined to a shaped ceramic part. The shaped ceramic part has a depression.
