Abstract

Systems and methods for detecting the presence of a body (typically a human) in a network without fiducial elements while additionally using fiducial elements to assist the system and possibly reduce the computational loading on the system. The fiducial element may be used in many ways including, without limitation, assisting in ignoring some bodies present in the detection area and training the system using additional data.

First claim

The invention claimed is:

1. A method for detecting the location of an object within a detection area, the method comprising:
providing a first transceiver disposed at a first location within a detection area;
providing a second transceiver disposed at a second location within said detection area;
a computer server communicably coupled to said first transceiver;
said first transceiver receiving a first set of wireless signals from said second transceiver when a first object carrying a fiducial element is present within said detection area at a first position;
said computer server receiving a first set of signal data from said first transceiver, said first set of signal data comprising data about properties of said first set of wireless signals;
said computer server receiving from said fiducial element, an indicator of said first position;
said computer server creating a first baseline signal profile for wireless communications from said second transceiver to said first transceiver, said first baseline signal profile being based at least in part on said properties of said first set of wireless signals in said first set of signal data when said first object is present in said detection area at said first position;
said computer server associating said first baseline signal profile with said first position;
said first transceiver receiving a new set of wireless signals from said second transceiver when a new object without a fiducial element is present in said detection area at an unknown position;
said computer server receiving a new set of signal data from said first transceiver, said new set of signal data comprising data about properties of said new set of wireless signals;
said computer server comparing said new set of signal data to said first baseline signal profile; and
said computer server indicating said new object is at said first location based on a comparison of said new set of signal data to said first baseline signal profile.

2. The method of claim 1 further comprising:
said first object moving from said first position to a second position in said detection area;
said first transceiver receiving a second set of wireless signals from said second transceiver when said first object is present at said second position;
said computer server receiving a second set of signal data from said first transceiver, said second set of signal data comprising data about properties of said second set of wireless signals;
said computer server receiving from said fiducial element, an indicator of said second position;
said computer server creating a second baseline signal profile for wireless communications from said second transceiver to said first transceiver, said first baseline signal profile being based at least in part on said properties of said first set of wireless signals in said first set of signal data when said first object is present in said detection area at said second position;
said computer server associating said second baseline signal profile with said second position;
said computer server comparing said new set of signal data to said second baseline signal profile; and
said computer server indicating said new object is at said second location based on a comparison of said new set of signal data to said second baseline signal profile.

3. The method of claim 2 wherein said first object is a human being.

4. The method of claim 3 wherein said new object is a human being.

5. The method of claim 4 wherein said first object and said new object are the same human being.

6. The method of claim 2 wherein said new object is a human being.

7. The method of claim 1 , wherein said properties of said first set of wireless signals comprise wireless network signal protocol properties determined by said first transceiver.

8. The method of claim 7 , wherein said each of said wireless network signal protocol properties is selected from the group consisting of: received signal strength, latency, and bit error rate.

9. The method of claim 1 , wherein said computer server operates an external system when said computer server indicates said object is at said first location.

10. The method of claim 9 , wherein said external system comprises an electrical system, a lighting system, a heating, venting, and cooling (HVAC) system, a security system, or an industrial automation system.

11. The method of claim 1 , wherein said first set of wireless signals utilizes a protocol selected from the group consisting of:
Bluetooth™, Bluetooth™ Low Energy, ANT, ANT+, WiFi, Zigbee, Thread, and Z-Wave.

12. The method of claim 1 , wherein said first set of wireless signals have a carrier frequency in the range of 850 MHz and 17.5 GHz inclusive.

13. The method of claim 1 wherein said first transceiver and said second transceiver are configured to calculate their relative positions within said detection area automatically.

14. The method of claim 1 wherein said first transceiver and said second transceiver are configured to define automatically a detection area including said first transceiver and said second transceiver.

15. The method of claim 1 wherein said first object is a human being.

16. The method of claim 15 wherein said new object is a human being.

17. The method of claim 16 wherein said first object and said new object are the same human being.

18. The method of claim 1 wherein said new object is a human being.

19. A method for determining the presence of a target object within a detection area, the method comprising:
providing a first transceiver disposed at a first location within a detection area;
providing a second transceiver disposed at a second location within said detection area;
a computer server communicably coupled to said first transceiver;
said first transceiver receiving a first set of wireless signals from said second transceiver when a calibration object is present within said detection area;
said computer server receiving a first set of signal data from said first transceiver, said first set of signal data comprising data about properties of said first set of wireless signals;
said computer server creating a first baseline signal profile for wireless communications from said second transceiver to said first transceiver, said first baseline signal profile being based at least in part on said properties of said first set of wireless signals in said first set of signal data when said calibration object is present in said detection area;
said first transceiver receiving a first new set of wireless signals from said second transceiver when a new object with a fiducial element is present in said detection area;
said computer server receiving a first new set of signal data from said first transceiver, said first new set of signal data comprising data about properties of said first new set of wireless signals;
said first transceiver receiving a second new set of wireless signals from said second transceiver when said object without a fiducial element is present in said detection area;
said computer server receiving a second new set of signal data from said first transceiver, said second new set of signal data comprising data about properties of said second new set of wireless signals;
said computer server rejecting said new object as said target object due to said computer server detecting said fiducial element, said rejection occurring regardless of comparison of said first new set of signal data to said baseline signal profile; and
said computer server determining said target object is within said
