Zusammenfassung:	This disclosure provides a method of determining a cartridge type of a cartridge used with a fluid drug injection system having a pump that receives a fluid drug cartridge. The fluid drug cartridge has a barrel filled with a fluid drug solution and a plunger within the barrel that forces the fluid drug solution through an outlet. An actuator of the pump is moved to contact or to move the plunger and a force sensor is used to measure force data during the movement. The force data is descriptive of the force applied to the plunger. A feature signal is determined from the force data. The feature signal can be a force modulation amplitude, a force modulation duration or a force modulation number. The cartridge type is assigned using the feature signal. Also disclosed is a fluid drug injection system and a cartridge for use therewith.
