Liquid delivery cap with alignment verification

Abstract

A cap device for a liquid delivery device operates to detect a position of the liquid delivery device relative to the cap device as the liquid delivery device is inserted to the cap device and rotated relative to the cap device. The cap device includes one or more sensors configured to detect a position of the liquid delivery device relative to the cap device. The position of the liquid delivery device can be used to determine whether the liquid delivery device is inserted and arranged in an appropriate axial and/or radial position relative to the cap device so that the cap device can accurately detect a condition of the liquid delivery device.
