Monitoring activities of daily living using radio frequency emissions
First Claim
1. A method, comprising:
- passively scanning an RF spectrum of the RF ambient environment of a building;
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 an identity of the detected 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, wherein determining the identity of the detected device comprises determining a device type of the detected device based on the RF signature of the device;
if the RF signature of the detected RF signal is found in the local 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.

Abstract
Briefly, in accordance with one or more embodiments, a monitoring system is capable of monitoring the Activities of Daily Living (ADL) of one or more persons occupying a building. The monitoring system includes an information handling system having a radio-frequency (RF) scanner capable of scanning the RF ambient environment of the building. When an individual uses devices in the building that emit RF signals or emissions, the RF signals are detected by the RF scanner and analyzed by the information handling system. The characteristics of the detected RF signals are compared to a database of signature of known devices. If a detected RF signal matches the signature of a known device, the use of the device is logged into a database for ADL analysis.
