A pyromechanical disconnecting device that includes a housing having a receiving space for an ignition element and a supporting floor. According to the method of the invention gradient vectors of voxel values are computed and are replaced by an index into a gradient look up table, thereby reducing the amount of required memory as well as the number of memory accesses during rendering. The bio-workstation primarily comprises of a nanomanipulator stage with a plurality of nano-positioners attached to a cabinet with a piezo voltage source and a pressure injector.
