Abstract: In one general aspect, a method is described. The method includes generating a positional relationship between one or more support structures having at least one motion capture mark and at least one virtual structure corresponding to geometry of an object to be tracked and positioning the support structures on the object to be tracked. The support structures has sufficient rigidity that, if there are multiple marks, the marks on each support structure maintain substantially fixed distances from each other in response to movement by the object. The method also includes determining an effective quantity of ray traces between one or more camera views and one or more marks on the support structures, and estimating an orientation of the virtual structure by aligning the determined effective quantity of ray traces with a known configuration of marks on the support structures.

Abstract: The invention relates to a method for the operation of a laboratory centrifuge (1), wherein a rotor (2) rotates around a horizontal rotational axis (3). It should be avoided that during the start-up of the laboratory centrifuge (1) or the deceleration of the laboratory centrifuge (1) for small angular velocities and small centrifugal forces resulting therefrom due to the gravitational acceleration the product (6) is biased by resulting components of the acceleration in vertical direction which change their sense of direction. For this purpose the acceleration of the rotor (2) is chosen such that when arriving for the first time in a reversing angular position (twelve o'clock position) there is already a centrifugal acceleration being larger than the gravitational acceleration. The corresponding applies for the deceleration of the rotor after the centrifugation.
