CLAIMS^

What is claimed is:

1. A geo-fencing system (102), comprising:

a base device (104) configured to create a virtual fence (108) around the base device that bounds a safe zone (1 10);

a wearable device (106) initially located within the safe zone; and

a processor configured to execute a dynamic adaptive control algorithm that computes at least one operating parameter for at least one of the base device and the wearable device based on a dynamic and adaptive combination of different signals indicative of distance measurements between the wearable device and the base device computed by the at least one of the base device and the wearable device,

wherein the processor conveys the at least one operating parameter to the at least one of the base device and the wearable device, which employs the at least one operating parameter for operation and determination of subsequent distance measurements.

2. The geo-fencing system of claim 1, wherein the processor computes the dynamic and adaptive combination based on one of a fixed combination of the signals, an invariant and dynamic combination of the signals, and a dynamic combination of the signal in time.

3. The geo-fencing system of any of claims 1 to 2, wherein the dynamic and adaptive combination is dependent on at least one of a surrounding environment, a position of the wearable device within the geo-fence, a movement of the wearable device, a location of another object within the geo-fence.

4. The geo-fencing system of any of claims 1 to 3, wherein the at least one operating parameter includes at least one of a frequency level signal, and a power amplification signal, and a power amplification level signal.

5. The geo-fencing system of any of claims 1 to 4, wherein at least one of the base device and the wearable device determines the signal based on one or more of a received signal strength indicator signal, a time of flight signal, a sine phase signal, a Wi-Fi 33 signal, global positioning signal, a quality indicator signal, a wearable device position signal, or a wearable device speed signal.

6. The geo-fencing system of any of claims 1 to 5, the processor is configured to combine the signals using a historic distance and an operating parameter data and one or more physical limitations of the system.

7. The geo-fencing system of any of claims 1 to 6, wherein the virtual fence is a circular fence with a radius (123).

8. The geo-fencing system of any of claims 1 to 7, wherein the processor is a processor of the base device.

9. The geo-fencing system of any of claims 1 to 8, wherein the processor is a processor of the wearable device.

10. The geo-fencing system of any of claims 1 to 9, wherein the base device is located at a center region of a safe zone, and at least one of the base device (104) or the wearable device (106) transmits an alarm in response to the wearable device (106) moving outside of the safe zone.

1 1. A method for establishing a geo-fence safe zone, comprising:

placing a wearable device and a portable wireless device (122) at a predetermined distance from a base device;

activating software of the portable wireless device to measure at least one distance between the portable wireless device and the base device;

adding a predetermined margin to the distance;

creating a geo-fence with a radius equal to the distance with the added margin; registering the geo-fence with the base and wearable devices; and

activating the base device and the wearable device to monitor a location of the wearable device.

12. The method of claim 1 1, further comprising:

determining a location of the wearable device;

comparing the determined location with the radius; and

transmitting an alarm in response to the wearable device exceeding the radius.

13. The method of any of claims 11 to 12, further comprising:

visually displaying the measured locations with respect to the based device and each other when a measurement is acquired and before creating the geo-fence.

14. The method of any of claims 11 to 13, further comprising:

receiving an input signal accepting the created geo-fence.

15. The method of any of claims 11 to 13, further comprising:

receiving an input signal rejecting the created geo-fence.

16. The method of any of claims 11 to 15, further comprising:

providing the wearable device with portable power for configuring the geo-fence safe zone.

17. The method of any of claims 11 to 16, further comprising:

installing the base device close to a center of a facility, wherein the geo-fence safe zone surrounds the facility.

18. The method of any of claims 11 to 17, further comprising:

installing the software application on the portable wireless device, wherein the software application at least includes a safe zone feature for configuring the safe zone.

19. A method, comprising:

reading in multiple signals indicative of distance measurements from electronics of at least one of a base device and a wearable device as a function of time;

dynamically and adaptively combining the distance measurements at different frequencies and power settings using historic data and physical limitations; and

determining device setting at least one of the base device and the wearable device based on the combination of distance measurements.

20. The method of claim 19, further comprising:

configuring a geo-fence safe zone with a software application on a smartphone prior to the acts of reading, combining and determining.
