What we have achieved since last time Completely automated hydraulic permeability experiment Calculates hydraulic permeability Log mass and pressure data Change pressure automatically Easily Input different pressures and masses Hardware communication (less for syringe pump) Results of pulsatile testing Added a second reservoir (capacitance) Reduced noise from +/-0.5 psi to +/-0.05 psi
