Safe zone creation to reduce power consumption in an electronic digital tracking device

1. A data processing method comprising:

determining, by an electronic digital tracking device comprising one or more processors, that the tracking device is outside a domicile;

monitoring, by the tracking device, a location of the tracking device;

in response to the location satisfying a condition, creating and storing in memory digital data defining a safe zone for the tracking device;

while the tracking device is within the safe zone, reducing power consumption of the tracking device by switching the monitoring of the location of the tracking device from using a first sensor to using a motion sensor, as part of reducing power consumption of the tracking device.

2. The method of claim 1 , wherein the first sensor is a GPS receiver, and wherein the second sensor is a motion sensor.

3. The method of claim 1 , further comprising determining that the tracking device is outside the domicile is based on an absence of a first signal from a first beacon generator.

4. The method of claim 3 , wherein the first beacon generator includes a battery charger capable of charging a battery of the tracking device.

5. The method of claim 3 , wherein the condition is the presence of a second signal from a second beacon generator.

6. The method of claim 1 , wherein the condition is an amount of time spent at the location.

7. The method of claim 1 , further comprising adjusting a signal strength parameter in response to the tracking device increasing power consumption without a breach occurring.

8. A computer system comprising:

a beacon generator that is programmed to produce a signal;

a tracking device comprising a plurality of sensors, a processor, and a non-transitory computer-readable storage media storing instructions which, when executed by the processor, cause:

determining that the tracking device is outside a domicile;

monitoring, a location of the tracking device;

in response to the location satisfying a condition, creating and storing digital data in the storage media that defines a safe zone;

while the tracking device is within the safe zone, reducing power consumption of the tracking device by switching the monitoring of the location of the tracking device from using a first sensor to using a motion sensor, as part of reducing power consumption of the tracking device.

9. The system of claim 8 , wherein the first sensor is a GPS receiver, and wherein the second sensor is an accelerometer.

10. The system of claim 8 , further comprising instructions stored in the storage media which when executed cause determining that the tracking device is outside the domicile based on an absence of the signal.

11. The system of claim 10 , wherein the beacon generator further comprises a battery charger capable of charging a battery of the tracking device.

12. The system of claim 8 , wherein the condition is an amount of time spent at the location.

13. The system of claim 8 , wherein the computer-readable media comprises instructions which, when executed by the processor, further cause adjusting a signal strength parameter in response to the tracking device increasing power consumption without a breach occurring.

14. A method comprising:

by a tracking device, with a short range receiver (SRR) in the tracking device, determining that the tracking device is in a domicile;

setting, by the tracking device, the SRR to a low power state and monitoring the tracking device for motion using a motion sensor;

in response to detecting motion of the tracking device using the motion sensor, activating the SRR and determining whether the tracking device is in the domicile.

15. The method of claim 14 , further comprising:

when the tracking device is not in the domicile, activating a GPS sensor in the tracking device and determining a location of the tracking device using the GPS sensor.

16. The method of claim 15 , further comprising:

determining that the location is outside the domicile;

in response to determining that the location is outside the domicile, generating and sending an alert message from the tracking device to a server.

17. The method of claim 14 , further comprising, in response to determining that the tracking device is in the domicile, returning the SRR to the low power state.
