Abstract
In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.
Claims21
A method of detecting a status of a human being, the method comprising:
- transferring, using a wireless transmitter, a wireless signal being selected from one or more of a frequency being less than about 10 G Hz, 24 G Hz, 60 G Hz, or 77 G Hz and greater;
- capturing a back scattered signal from the wireless signal;
- processing the back scattered signal to extract one or more of a direction, signal strength, distance, and other information over a time period;
- extracting, using a signal processing process, received vital signs of a human, the vital signs including a heart rate, or a respiration rate;
- creating a baseline for each of the received vital signs;
- extracting, using an AI process, a physical activity of the human being;
- creating a physical activity base line for the physical activity;
- determining a confidence level of each of the received vital signals and each of the physical activities;
- transferring an alert to another target upon a triggering even based upon the confidence level of each of the received vital signals and each of the physical activities;
- and
- correlating each received vital sign, using an artificial intelligence process, with one or more patterns or the base line for each of the received vital signs.
