Abstract
Abstract A rate-of-rotation sensor comprises an oscillatory mass on which an acceleration sensor is disposed so that the acceleration sensor can be deflected parallel to the surface of the oscillatory mass. With this arrangement, a measurement of the Coriolis force parallel to the surface of the oscillatory mass is possible.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A rate-of-rotation sensor comprising: a plurality of webs elongated in a first direction, the plurality of webs being arranged parallel to one another in the first direction; an oscillatory system including at least one oscillatory mass suspended on the plurality of webs; means for exciting the oscillatory system into oscillations in a second direction, the second direction being perpendicular to the first direction; and at least one acceleration sensor, coupled to the oscillatory system, for detecting an acceleration in the first direction.
Claim 2
Dependent Claim
82 words
A rate-of-rotation sensor comprising: a plurality of webs elongated in a first direction, the plurality of webs being arranged parallel to one another in the first direction; an oscillatory system including at least one oscillatory mass suspended on the plurality of webs; means for exciting the oscillatory system into oscillations in a second direction, the second direction being perpendicular to the first direction; and at least one acceleration sensor, coupled to the oscillatory system, for detecting an acceleration in the first direction.
Claim 3
Dependent Claim
12 words
The sensor according to claim 1, wherein the acceleration sensor is comb-shaped.
Claim 4
Dependent Claim
57 words
The sensor according to claim 1, wherein the acceleration sensor includes: first and second transverse beams coupled to the oscillatory system, and a deflectable mass having first and second ends connected to the first and second transverse beams, respectively, and wherein the first and second transverse beams suppress deflection of the deflectable mass in the second direction.
Claim 5
Dependent Claim
45 words
The sensor according to claim 1, further comprising: a frame; and at least two doubly folded webs for suspending the oscillatory system on the frame such that, when the oscillatory system oscillates in the second direction, the webs are stressed only with respect to bending.
Claim 6
Dependent Claim
55 words
The sensor according to claim 4, further comprising: a second oscillatory system coupled to the frame; a second acceleration sensor coupled to the second oscillatory system; and at least one further web for coupling the oscillatory system to the second oscillatory system such that the oscillatory system and the second oscillatory system oscillate in antiphase.
Claim 7
Dependent Claim
15 words
The sensor according to claim 5, wherein the further web is at least doubly folded.
