Abstract

An aerosol delivery device includes at least one housing; and contained within the at least one housing, a control component and motion sensor. The control component may control operation of the aerosol delivery device based on a detected flow of air through at least a portion of the at least one housing. The motion sensor may detect a defined motion of the aerosol delivery device that indicates a vulnerability of the aerosol delivery device or a user thereof, with the motion sensor being configured to convert the defined motion to an electrical signal. The control component or motion sensor may recognize the vulnerability and an operation associated with the vulnerability based on the electrical signal, and the control component may control at least one functional element of the aerosol delivery device to perform the operation, which may thereby be performed in response to detection of the vulnerability.
