Abstract

Examples of device separation monitors are described herein. In some examples, a first electronic device may include a memory. In some examples, the first electronic device may include a processor in electronic communication with the memory. In some examples, the processor may monitor for separation from a second electronic device based on a geographic location detection zone. In some examples, the processor may detect a zone type switch event. In some examples, the processor may monitor for separation from the second electronic device based on a wireless detection zone in response to detecting the zone type switch event.

First claim

The invention claimed is:

1 . An electronic device, comprising:
a memory; a processor in electronic communication with the memory, wherein the processor is to:
monitor for separation from a second electronic device based on a geographic location detection zone, wherein to monitor for separation from the second electronic device based on the geographic location detection zone, the processor is to:
determine whether a first electronic device location is outside of the geographic location detection zone from the second electronic device; and
provide an alert in response to determining that the first electronic device location is outside of the geographic location detection zone;

while monitoring for separation from the second electronic device based on the geographic location detection zone, detect a zone type switch event; and
monitor for separation from the second electronic device based on a wireless detection zone in response to detecting the zone type switch event.

2 . The electronic device of claim 1 , wherein to detect the zone type switch event, the processor is to detect a wireless signal from a vehicle.

3 . The electronic device of claim 1 , wherein to detect the zone type switch event, the processor is to detect satisfaction of a proximity criterion based on a wireless signal from a vehicle.

4 . The electronic device of claim 1 , wherein the processor is to detect the zone type switch event by detecting arming of a building security device.

5 . The electronic device of claim 1 , wherein to monitor for separation from the second electronic device based on the wireless detection zone, the processor is to determine whether a wireless signal is received from the second electronic device.

6 . The electronic device of claim 5 , wherein to monitor for separation from the second electronic device based on the wireless detection zone, the processor is to:
determine whether a strength of the wireless signal satisfies a threshold in response to determining that the wireless signal is received from the second electronic device; and provide an alert in response to determining that the strength of the wireless signal does not satisfy the threshold.

7 . The electronic device of claim 1 , wherein the processor is to:
while monitoring for separation from the second electronic device based on the wireless detection zone, detect a second zone type switch event; and monitor for separation from the second electronic device based on the geographic location detection zone in response to detecting the second zone type switch event.

8 . The electronic device of claim 7 , wherein to detect the second zone type switch event, the processor is to detect a loss of a wireless signal from a vehicle.

9 . The electronic device of claim 1 , wherein to monitor for separation from the second electronic device based on the geographic location detection zone, the processor is to utilize a position of the electronic device and a position of the second electronic device.

10 . A non-transitory tangible computer-readable medium comprising instructions when executed cause a processor of an electronic device to:
track group device separation based on a geographic location of a device relative to a geographic zone, wherein to track group device separation, the processor is to:
determine whether the device is outside of the geographic zone; and
provide an alert in response to determining that the device is outside of the geographic zone;
while tracking group device separation based on the geographic location of the device relative to the geographic zone, detect that a vehicle is activated based on a wireless signal; and switch to track group device separation based on wireless signal detection in response to detecting that the vehicle is activated.

11 . The computer-readable medium of claim 10 , wherein the instructions when executed further cause the processor to compare a received identifier with a stored vehicle identifier.

12 . The computer-readable medium of claim 10 , wherein the geographic zone is larger than a wireless signal detection range.

13 . The computer-readable medium of claim 10 , wherein the instructions when executed cause the processor to detect that the vehicle is activated by comparing a vehicle identification information stored in the electronic device with identifier information from the wireless signal.

14 . The computer-readable medium of claim 10 , wherein the instructions when executed cause the processor to track group device separation based on the geographic location of the device relative to the geographic zone without using a beacon signal between the device and another device.

15 . The computer-readable medium of claim 10 , wherein the instructions when executed cause the processor to track group device separation based on wireless signal detection without using a geographic location.

16 . The computer-readable medium of claim 10 , wherein the instructions when executed cause the processor to, while tracking group device separation based on wireless signal detection, provide an alert in response to determining that a strength of the wireless signal does not satisfy a threshold.

17 . The computer-readable medium of claim 10 , wherein the instructions when executed cause the processor to:
while tracking group device separation based on the wireless signal detection, detect that the vehicle is deactivated based on the wireless signal; and switch to track group device separation based on the geographic location of the device relative to the geographic zone in response to detecting that the vehicle is deactivated.

18 . The computer-readable medium of claim 17 , wherein the instructions when executed cause the processor to detect that the vehicle is deactivated by detecting a loss of the wireless signal from the vehicle.
