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

1 . A method for detecting human presence, the method comprising:
providing at least two transceivers exchanging data bi-directionally via wireless signals; receiving as first set of signal data, said first set of signal data comprising data about the properties of a first set of wireless signals, said property data being generated as part of said exchanging data; 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; receiving a second set of signal data, said second set of signal data comprising data about the properties of a second set of wireless signals, said property data being generated as part of said exchanging data; 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 received 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+, Zigbee, and Z-Wave.

11 . A system for detecting human presence, the system comprising:
at least two transceivers exchanging data bi-directionally via wireless signals; means for receiving a first set of signal data, said first set of signal data comprising data about the properties of a first set of wireless signals, said property data being generated as part of said exchanging data; means for 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 said detection area; means for receiving a second set of signal data, said second set of signal data comprising data about the properties of a second set of wireless signals, said property data being generated as part of said exchanging data; means for determining whether a human is present within said detection area, 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.

12 . The system of claim 11 , wherein said first set of signal properties comprise wireless network signal protocol properties.

13 . The system of claim 12 , wherein said wireless network signal protocol properties are selected from the group consisting of: received signal strength, latency, and bit error rate.

14 . The system of claim 11 , wherein said determining comprises applying statistical methods to said second set of wireless signal data.

15 . The system of claim 11 , wherein said means for receiving continuously receives sets of signal data from said bi-directional data exchange.

16 . The system of claim 11 , further comprising:
means for 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.

17 . The system of claim 16 , further comprising:
means for 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.

18 . The system of claim 11 , further comprising:
a second system which alters an environmental variable in said area where said wireless signals are being transmitted only after determining a human is present in said area where said wireless signals are being transmitted.

19 . The system of claim 18 , 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.

20 . The system of claim 11 , 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+, Zigbee, and Z-Wave.
