Abstract
A computer system is communicably coupled to one or more sensor devices. The computer system obtains a database of stored acoustic signatures characterizing predefined acoustic signals generated by passive tags in response to physical motion of respective monitored objects associated with the passive tags. A first acoustic signal characterized by a respective acoustic signature and generated by a first passive tag is detected. In response, and based on the respective acoustic signature and information in the database, a first monitored object associated with the respective acoustic signature is identified, and a first state of the first monitored object is determined. The determined first state is stored in the database, and an indication of the first state is provided to an associated monitoring service.
