Abstract: An autoinjector drug delivery device configured with a stall and endpoint detection algorithm is described that allows for variations in the fill of the drug, barrel, plunger, and other components. The stall or end point detection causes the autoinjector to stop an extrusion process.

Abstract: This disclosure describes a drug delivery device with communication functionality for purposes of transferring information to a user device, such as a smartphone, while maintaining power-efficient operation. The drug delivery device comprises a controller configured to, while operating in the active mode, use one or more sensors to detect that the injection mechanism has performed an injection. The controller is also configured to generate in memory a data entry indicative of the injection and/or a state of the drug delivery device, and switch into the low-power mode subsequent to or contemporaneous with detecting that the injection mechanism has performed the injection. The drug delivery device also comprises a wireless communication module powered by the power source and configured to establish a wireless connection with and transfer a message to a user device while the controller is operating in the low-power mode.
