The control arithmetic is proposed for axial blood pump driven by extracorporeal alternating magnet field based on ventricular work. According to health physiological parameters, the control model is verified by calculation and experiment. The control model used for driving blood pump is derived from the relationship of natural heart and artificial heart.… (More)
This essay introduces the new development of rotary impeller blood pump technology in three design aspects, i.e. pump structure, bearing and seal, control system. Moreover, an expectation for the development trend of artificial heart technology is presented.
This paper presented a fast algorithm which could measure similarity between two meshes interactively. The algorithm was based on CUDA (Compute Unified Device Architecture) technology. In order to fully utilize the computing power of GPU, we developed parallel method to construct uniform grid for fast space indexing of triangles. Special data structure was… (More)
