Monitoring activities of daily living using radio frequency emissions

An apparatus, comprising:

• an RF scanner coupled to an antenna to passively scan the RF spectrum in the RF ambient environment of a building;
• and
• a processor coupled to said RF scanner, said processor being capable of:
• detecting an RF signal in the scanned RF spectrum emitted from a device in the building, the detected RF signal comprising an RF signature of the device as the device is operated or used by a user,
• determining a device type of the detected device based on determining an identity of the device by finding the RF signature of the detected RF signal in a local database of known device RF signatures in the RF ambient environment of the building and obtaining a device identification associated with the RF signature in the local database,
• if the RF signature of the detected RF signal matches a known device RF signature in the database, storing, in a log of activities occurring in the building, usage information of the detected device as the detected device is operated or used by the user, and
• analyzing the log of activities occurring in the building to determine a status of the user in the building.
