Abstract
In an example, the present invention provides a method for identifying a status of a user and providing feedback to the user based upon the status of the user. In an example, the method includes generating an electromagnetic radio frequency (RF) signal from an RF generating device and emitting the electromagnetic RF signal into a spatial region of a user. In an example, the method includes detecting a back scattered RF signal, using an RF receiving antenna, from the user and converting the back scattered RF signal from an RF analog signal into an RF digital signal.
Claims18
A method for identifying a fall status of a user, comprising:
- emitting a radiofrequency (RF) signal from a RF transceiver, toward the user;
- receiving a backscattered RF signal with the RF transceiver, the backscattered RF signal backscattered from the user;
- using an audio sensor to sense a sound produced by the user;
- identifying the fall status of the user based on both the backscattered RF signal and the sensed sound;
- and
- providing a feedback to the user or a third party based on the identified fall status, wherein the feedback provides notification of the fall status to the third party or the feedback assists the user.
A system for identifying a fall status of a user, comprising:
- a radiofrequency (RF) transceiver configured to emit a RF signal and to receive a backscattered RF signal backscattered from the user;
- an audio sensor configured to sense a sound produced by the user;
- a processor operably coupled to the RF transceiver and the audio sensor;
- and
- a memory operably coupled to the processor storing thereon instructions to cause the processor to execute a method, comprising:
- identifying the fall status of the user based on both the backscattered RF signal and the sound produced by the user;
- and
- providing a feedback to the user or a third party, wherein the feedback provides notification of the fall status to the third party or the feedback assists the user.
