Figure 5From: A simplified cervix model in response to induction balloon in pre-labourFeedback-based control of the sliding joint spring, with no pin joint spring. Feedback-based control of only the sliding joint spring, with dilation speed ramping up to a steady-state of 0.692 c m·h r-1, shown in (a). The maximum spring constant, shown in (b), is 23800 N·m-1.Back to article page
