Abstract
Medication delivery devices, sensing systems, and methods are disclosed for determining the relative axial and rotational movements of its members to determine the amount of a dose set and/or delivered by the medication delivery device. A sensing system comprises a barrel sensor system (), a drive sleeve sensor system (), and/or an axial sensor system (). The barrel sensor system () is for detecting the absolute relative angular position of the barrel relative to the housing during dose setting. The drive sleeve sensor system () is for detecting the absolute relative angular position of the drive sleeve relative to the housing during dose delivery. The axial sensor system () is for detecting the relative axial positions of the dose dial relative to the housing during dose setting and delivery. A controller receives outputs from the sensor systems corresponding to the absolute relative positions to determine the actual amounts of dose set and delivered.
