Abstract: A drug delivery device adapted to receive a drug-filled cartridge (10), comprising dose setting means allowing a user to set a desired dose of drug to be expelled, an electronic controller (70,270) adapted to control a motor (51) to move a drive member to thereby expel an amount of drug from a received cartridge corresponding to a set dose, and means for estimating the amount of free air in a loaded cartridge. The controller is adapted to detect an error state if the estimated amount of free air in the cartridge is larger than or equals a given percentage of the amount of drug corresponding to a set dose.

Abstract: A drug delivery system comprising a controller adapted to detect when a given user-actuated operation being part of the expelling of an amount of drug is performed, record detected operations as a function of time, and estimate, based on recorded operations, time parameters for the detected operations, thereby providing time parameters for a medical regimen on which the detected operations are assumed to be based upon.

Abstract: A communications device for wireless communication with another device, the communications device having a) a first part having a first housing and a first induction coil for providing an inductive coupling to the other device, and b) a second part having a second induction coil adapted to be inductively coupled to said first induction coil and to said other device when mounted on or near said first housing. Provided is a relatively simple mechanical interface for an inductively coupled link between a communications device and another device. The second part is adapted to be detachably attachable to the first housing. An advantage is that no connector is needed whereby a simpler and more reliable device is provided. The consequences of wear of the connector leading to increased contact resistance and/or failure of the electrical connection is avoided.
