Abstract

A tracking system in which positioning alerts are communicated to a first user device from a second user device, the tracking system including a positioning sensor that determines a current location of the second user device; a controller in communication with the positioning sensor; and a memory including instructions to: receive a first set of current locations from the positioning sensor, generate, at a start of a candidacy period, a candidate geofence including the first set, receive a second set of current locations from the positioning sensor, when, by an end of the candidacy period, the entirety of the second is within the candidate geofence, communicate a stop motion message to the first user device, receive a third set of current locations from the positioning sensor, and when any of the third set is outside an active geofence, communicate a start motion message to the first user device.

Claims

1. A tracking system in which positioning alerts are communicated to a first user device from a second user device, the tracking system comprising:

a positioning sensor included in the second user device, wherein the positioning sensor determines a current location of the second user device;

a controller in communication with the positioning sensor; and

a memory in communication with the controller, the memory including instructions that when executed by the controller cause it to;

receive a first set of current locations from the positioning sensor,

generate, at a start of a candidacy period, a candidate geofence including the first set,

receive a second set of current locations from the positioning sensor,

when, by an end of the candidacy period, the entirety of the second set of current locations is within the candidate geofence, communicate a stop motion message to the first user device,

receive a third set of current locations from the positioning sensor, and

when any of the third set of current locations are outside an active geofence, start a timer,

receive a fourth set of current locations upon the timer reaching a delay time, and

upon the timer reaching the delay time, when any of the fourth set of current locations is outside the active geofence, communicate a start motion message to the first user device.

2. The system of claim 1, wherein the memory further includes instructions to:

receive a fifth set of current locations between starting the timer and the timer reaching the delay time,

upon the timer reaching the delay time, when the second set of current locations is within the active geofence, update the active geofence to include an area including the fifth set.

3. The system of claim 1, wherein the memory further includes instructions to:

when, before the end of the candidacy period, any of the second set of current locations is outside of the candidate geofence, return to the step of receiving a first set of current locations from the positioning sensor.

4. The system of claim 1, wherein the memory further includes instructions to:

when, by the end of the candidacy period, the entirety of the second set of current locations is within the candidate geofence, accept the candidate geofence as the active geofence.

5. The system of claim 1, wherein the memory further includes instructions to:

when, by the end of the period, the entirety of the second set of current locations is within the candidate geofence and the active geofence overlaps with the candidate geofence, update the active geofence to include the candidate geofence.

6. The system of claim 1, wherein the controller and the memory are physically connected to the second user device.

7. The system of claim 1, wherein the controller and the memory are physically connected to a tracking server.

8. The system of claim 1, wherein the candidate geofence encompasses a radial area centered on the first set, wherein a radius of the radial area is user-selected.

9. The system of claim 1, wherein the step of communicating a stop motion message includes a communication using a web callback URL.

10. The system of claim 1, wherein the step of communicating the stop motion message to the first user device is accomplished by sending a first SMS message to the first user device, wherein the step of communicating the start motion message to the first user device is accomplished by sending a second SMS message to the first user device.
