Abstract
The present invention relates to a method and to a monitoring device for monitoring operation of a drug delivery device, the monitoring device comprising of at least a first and a second sensor arranged at a distance from each other with regard to a first direction and being adapted to generate a first and a second electrical signal in response to an operation of the device, a processing unit configured to determine a time delay between the first and the second electrical signals and being adapted to determine at least one state parameter of the drug delivery device on the basis of said time delay.

16. A monitoring device for monitoring operation of a drug delivery device, the monitoring device comprising:
-
at least a first and a second sensor arranged at a distance from each other with regard to a first direction and being adapted to generate a first and a second electrical signal in response to an operation of the device, wherein the first and second sensors are adapted to detect and/or to record one and the same detectable operation of the drug delivery device, a processing unit configured to determine a time delay between the first and the second electrical signals and being adapted to determine at least one parameter of the drug delivery device on the basis of said time delay. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for monitoring operation of a drug delivery device having a housing and a drive mechanism comprising at least one sound generating element movably disposed along a first direction relative to the housing, the method of operation monitoring comprises the steps of:
-
generating a sound during operation of the drive mechanism, detecting the sound by a first sensor and by a second sensor arranged at a distance from each other with regard to the first direction and generating first and second electrical signals in response to the sound detection, determining a time delay between the first and the second electrical signals and determining at least one parameter of the drug delivery device on the basis of the time delay. - View Dependent Claims (30)
