1. A medicament inhaler assembly, comprising:
- a housing defining a central void region disposed along a central axis;
a medicament container having an internal medicament containing reservoir, and extending along a container axis, and having at one end thereof, a dispensing port extending along said central axis, said dispensing port being coupled to said medicament containing reservoir, said medicament container containing a medicament disposed in said medicament containing reservoir, said medicament being in the form of a plurality of doses;
a dispensing means for dispensing said medicament from said medicament container, wherein in response to a user-induced motion said medicament container translates relative to said housing in a first direction along said central axis causing said medicament to be dispensed from said dispensing port;
an identification means for identifying said medicament container, said identification means configured for presenting information indicative of an identity of said container, wherein if said identity of said container is associated with said housing a first identifier is sent, and if said identity of said container is not associated with said housing a second identifier is sent;
a sleeve attached to said medicament container, wherein said identification means is attached to said sleeve;
a detector attached to said housing and adapted to detect said presented information from said identification means when said container is disposed in said central void region of said housing, wherein when said identification means sends said first identifier said detector generates a valid signal in response and when said identification means sends said second identifier said detector sends an invalid signal; and
a container state indicator assembly attached to said housing and said container, said container state indicator assembly including a detection means adapted for detecting a medicament dispensing motion of said medicament container relative to said housing, said container state indicator assembly further including a signaling means adapted for generating a signal indicative of a state of said medicament container.
