Abstract:
1. A method for alerting users of electronic devices when the electronic devices become physically separated from one another by more than an allowed distance, the method including: providing a first and a second electronic devices, wherein each of the electronic devices includes an application that is coupled to a digital service on the interne and a display for displaying alerts; receiving a first set of unique identification and global position system (“GPS”) coordinates from the first electronic device, wherein the first set from the first electronic device is received by the digital service; receiving a first set of unique identification and GPS coordinates from the second electronic device, wherein the first set from the second electronic device is received by the digital service; determining the first electronic device and the second electronic device are logically paired; setting a threshold maximum allowed physical separation distance between the first and the second electronic devices; computing a first physical distance between the first GPS coordinates and the second GPS coordinates and determining the first physical distance is less than the threshold maximum allowed physical distance; receiving a second set of unique identification and GPS coordinates from the first electronic device and a second set of unique identification and GPS coordinates from the second electronic device; computing a second physical distance between the first GPS coordinates and the second GPS coordinates and determining the second physical distance is greater than the threshold maximum allowed physical distance; in response to determining the second physical distance is greater than the threshold maximum allowed physical distance, transmitting an alert message to the first and to the second electronic devices; and displaying the alert message on the display of the first and the display of the second electronic devices.
