US Patent 10140838 Automatic transmission of reminders for devices left behind

A method for generating and transmitting a reminder message includes obtaining a unique user profile. The user profile includes a user identification (ID) indicative of a unique user, an object ID indicative of a unique object, and a device ID indicative of a unique mobile device. The processor is configured to predict a spatial relationship between the user, the object, and the mobile device. The prediction is based, in part, on the user ID, the object ID, and the device ID, where the prediction includes a geographic location for the user, the object, and/or the mobile device. The processor compares a location of at least two of the user, the object and the mobile device with the prediction of the user's spatial relationship with the object and the mobile device. The processor transmits a reminder message when the prediction of the spatial relationship exceeds a predetermined threshold.
