DETERMINING USE AND VALIDITY OF VEHICLES THROUGH ACOUSTIC EMISSIONS

Arrangements are provided for "smart" functionality with "dumb" containers, such as for determining medication adherence, tracking product use, and validating product authenticity. An acoustic emitter is engaged with a container or other vehicle. Opening the container causes the acoustic emitter to produce an acoustic emission, without requiring power, processing capacity, or sensors. A cell phone or other station receives and registers acoustic emissions, such as by logging opening of the container, verifying authenticity of the acoustic emission, communicating with an oversight system, or similar. Data as may be encoded in an acoustic emission may include vehicle detection data (e.g., logging a container being opened), vehicle information (e.g., lot number, contents name), vehicle validation (e.g., valid or counterfeit numerical code), and audible user recognition (e.g., brand jingles, warning sounds).
