Abstract: A breath actuated metered dose inhaler may comprise a canister fire system configured to fire a medicament containing canister in response to patient inhalation. The canister fire system may comprise a pneumatic force holding unit and having a rest configuration in which a metering valve of the canister is in a refill configuration; a prepared configuration in which a canister actuation force is retained by the pneumatic force holding unit and the canister fire system is actuatable by patient inhalation induced airflow; and a fire configuration in which the metering valve is in a dose delivery position. When in the prepared configuration, the force retained by the pneumatic force holding unit may be reduced by less than about 6% over a period of 5 minutes, preferably less than about 3% over a period of 5 minutes.

Abstract: One variation of a method for detecting breach events by residents of an assisted living facility includes: defining an access perimeter containing a first space and excluding a second space within a facility, the first space and the second space separated by a door; assigning the first individual access perimeter to a first resident, in a set of residents, occupying the facility; maintaining the door in an unlocked state by default during a first period of time; tracking locations of resident wearable devices associated with residents, in the set of residents, within the facility during the first period of time; and, in response to a first location of a first resident wearable device associated with the first resident falling inside the individual access perimeter and within a threshold distance of the door at a first time during the first period of time, triggering the door to enter a locked state.
