Amazon patents system to fix delayed location alerts for moving objects
This patent describes a method for handling location data that arrives out of sequence. If a device reports its position late, the system checks if the object entered or left a specific zone (geofence) before the late data arrived and sends a delayed notification to the user.
In the filing’s own words
A plurality of location indications may be received that indicate locations of an object at a plurality of times. A plurality of geofence indications that indicate that the object is within a geofence may be generated based on the plurality of location indications. A plurality of notifications of a plurality of geofence events corresponding to the object may be provided, to an account, based on the plurality of geofence indications. The plurality of geofence events may include a geofence entering event and a geofence exiting event. An out-of-order location indication may be detected within the plurality of location indications. A retroactive geofence event regarding which the account has not yet been notified may be determined based on the out-of-order location indication. An additional notification of the retroactive geofence event may be provided to the account.
