Abstract

Systems and methods for detecting the presence of a body in a network without fiducial elements, using signal absorption, and signal forward and reflected backscatter of RF waves caused by the presence of a biological mass in a communications network.

First claim

The invention claimed is:

1. A method for detecting human presence, the method comprising:
providing at least two transceivers exchanging data bi-directionally via wireless signals, said bi-directional exchange generating sets of wireless signals;
obtaining a first set of wireless signals from said sets of wireless signals, said first set of wireless signals having been generated when no human is present in an area where said wireless signals are being transmitted during said bi-directional exchange;
determining a first set of signal data, said first set of signal data comprising data about the properties of said first set of wireless signals, said property data being generated as part of said bi-directional exchange;
creating a baseline signal profile based at least in part on said first set of signal data, and representing characteristics of wireless transmissions between said at least two transceivers when no human is present in an area where said wireless signals are being transmitted;
determining a second set of signal data, said second set of signal data comprising data about the properties of a second set of wireless signals from said sets of wireless signals, said property data being generated as part of said bi-directional exchange;
determining whether a human is present within said area where said wireless signals are being transmitted, said determination based at least in part on a comparison of said wireless signal properties in said second set of wireless signal data to said baseline signal profile.

2. The method of claim 1 , wherein said first set of signal properties comprise wireless network signal protocol properties.

3. The method of claim 2 , wherein said wireless network signal protocol properties are selected from the group consisting of: received signal strength, latency, and bit error rate.

4. The method of claim 1 , wherein said determining comprises applying statistical methods to said second set of wireless signal data.

5. The method of claim 1 , further comprising:
continuously receiving sets of signal data from said bi-directional data exchange.

6. The method of claim 1 , further comprising:
determining a number of humans present within said area where said wireless signals are being transmitted, said determination based at least in part on a comparison of said wireless signal properties in said received second set of wireless signal data to said baseline signal profile.

7. The method of claim 6 , further comprising:
determining a location of one or more humans within said area where said wireless signals are being transmitted, said determination based at least in part on a comparison of said wireless signal properties in said received second set of wireless signal data to said baseline signal profile.

8. The method of claim 1 , further comprising:
only after determining a human is present in said area where said wireless signals are being transmitted, operating a second system which alters an environmental variable in said area where said wireless signals are being transmitted.

9. The method of claim 8 , wherein said second system is selected from the group consisting of: an electrical system; a lighting system; a heating, venting, and cooling (HVAC) system; and a security system.

10. The method of claim 1 , wherein said exchanging data bi-directionally via wireless signals utilizes a wireless communication protocol selected from the group consisting of: Bluetooth™, Bluetooth™ Low Energy, ANT, ANT+, WiFi, Zigbee, and Z-Wave.

11. The method of claim 1 further comprising placing a location of each of said at least two transceivers on a map of said area.

12. The method of claim 11 , further comprising determining a location of said human in said area based on said location of said at least two transceivers.

13. The method of claim 12 wherein said location of said human is relative to said location of said transceivers.

14. The method of claim 12 where said location of said human is relative said area.

15. The method of claim 12 further comprising determining said location of said human a plurality of times while said human is within said area.

16. The method of claim 15 further comprising predicting a location of said human at a future time based on said plurality of determinations.
