Patent ID: 7694588

Claim:
In an adjustment and stabilization unit ( 1 ) having a movable platform ( 3 ), a rotational mass ( 2 ) mounted on said platform ( 3 ) and stabilized in inertial space, an adjustment drive ( 6 ) for adjusting the position of said rotational mass ( 2 ), said adjustment drive ( 6 ) being connected to said rotational mass ( 2 ) and to said platform ( 3 ) and including a driving device ( 7 ) connecting said adjustment drive ( 6 ) with said rotational mass ( 2 ), a force-sensing device ( 16 ) for torque measurement, and at least one stabilization control circuit for controlling said adjustment drive ( 6 ) as a function of the measured torque, the improvement which comprises: said force-sensing device ( 16 ) having an annular design and being arranged between said platform ( 3 ) and said adjustment drive ( 6 ), wherein a portion ( 17 ) of said driving device ( 7 ) extends through said force-sensing device, and wherein said force-sensing device ( 16 ) measures the torque transmitted between said adjustment drive ( 6 ) and said platform ( 3 ) as a function of the acceleration of said rotational mass ( 2 ) relative to said adjustment drive ( 6 ).
