To a layman the two are nearly identical, however the Von Hiesen is an older model of Neutrino Compressors and thus shares many aesthetic components as the contemporary hypercarbolators (I tend to use the American spelling for that word) due to the placement of the backfeed tube.
gimbal and quaternions are two different ways of describing an object's rotation in 3d.
gimbal is very intuitive, you just write down three angles: pitch, roll, and yaw.
to imagine the objects rotation when I give you the three angles, you just apply them one after the other.
however, there is an issue. When the object's rotation is large enough that say, roll becomes 90, suddenly pitch and yaw correspond to the same 'thing '. which means one axis of rotation can no longer be realized.
in practice this can be seen with physical gimbals (three concentric rings, one per axis) or in numerical gimbal representation, where values might end up being unworkable.
quaternions eliminate this problem by using four values instead of three (quater, quattro, quad bike - the prefix stands for 4)
3 values are the components of a 3d vector, and the 4th is how much rotation to apply around it.
The above post argue that this 4th value seems like an extra degree of freedom, it isnt. it simply is a matter of representation if coded correctly.
