An actuator for superimposed steering engagement in a vehicle steering system having first and second input shafts, an output shaft coaxial with the first input shaft, and a superposition gear disposed between the shafts. The superposition gear has a two-stage, modified planetary gear that has respective sun wheels fixed on the first input shaft and the output shaft, respectively, a satellite carrier that can be driven by the second input shaft, and at least one stepped planet with two respective planet wheels that mesh with the sun wheels. The planet wheels are, spaced apart axially from one another, one on each end portion of a smaller-diameter shaft portion with which they are integral.

In a 3D magnetic resonance angiography (MRA) method, a region of interest, containing a major pulmonary vessel, is defined in an examination subject, and the subject is injected with a contrast agent bolus and a number of 3D magnetic resonance angiography data sets are obtained from the examination subject before, during and after arrival of the bolus in the region of interest. A slice from each of the data sets is selected which contains the region of interest, and an average region of interest signal as a function of time is determined and stored as a reference time curve. In the respective selected slices, a signal-time curve is identified and each signal-time curve is cross-correlated with the reference time curve. The cross-correlation results are used to form a new three-dimensional data set containing arterial and venous correlation maps. Maximum intensity projections are computed from the arterial and venous correlation maps for producing a visualized image of the pulmonary vasculature in the region of interest, the arteries and veins in the respective maximum intensity projections being clearly distinguishable.

The present invention relates to in-place soil stabilization. Specifically, the present invention relates a method and device for measuring the increase in subsurface earth pressure during the injection of a stabilizing agent into the soil. The rise in sensor pressure indicates an increase in soil strength and bearing capacity. Therefore, real-time monitoring of these pressures may serve as a guide during the injection process.
