Integration and testing of a real time processing unit for lung simulation
 Paštěka, Richard ; Drauschke, Andreas (oponent) ; Sekora, Jiří (vedoucí práce)
An active mechanical lung simulator (iLung) provides the possibility of simulating human breathing patterns. The aim of this thesis is to implement and test an real time embedded control and acquisition system cRIO as iLung control unit. Resulting connections are documented in tables and also by labelling assembly drawings with corresponding pin functions. One of the major improvements was made by tuning the motor and modifying the proportional-integral controller in the software. Those modifications resulted in significantly reduced motor oscillations around zero value. In order to increase usability and accessibility of the simulator a user manual and corresponding laboratory experiment were additionally created. The Validation of cRIO implementation was not limited to simple testing routines, but also extended on testing the simulator as a whole functioning unit. The results of simulator based measurements were compared and discussed to the spirometry measurements, taken from 20 subjects. Measurements showed a high degree of similarity between breathing patterns simulated by iLung and normal human breathing supporting the possibility for further research applications.
