Classification: CPC A | IPC A

Claim 15:
16. The method of claim 11, wherein
the injection device assembly further comprises a retraction mechanism configured to drive the syringe assembly from the injection position to a retracted position; and
the method further comprises:
analyzing, by the at least one processing circuit, the signal output by the accelerometer to detect a second acceleration spike subsequent to the first acceleration spike, and
determining, by the at least one processing circuit, that the second acceleration spike is caused by a retraction movement upon completion of the dispensing event in which the syringe assembly is driven by the retraction mechanism from the injection position to the retracted position when at least one of the one or more skin-contact sensors detect contact with skin tissue at a time when the second acceleration spike was detected.
