Abstract
A breast pump system includes a solenoid valve and a power source. The power source is arranged to supply electrical power to the solenoid valve so as enable the solenoid valve to move between first and second positions. The breast pump system also includes a controller configured to detect a change in inductance of the solenoid valve that is indicative of the solenoid valve moving from first to second position and a control action in which the vacuum pump is stopped.
