The patent application (Publication Number: US20240015478A1) describes a method and system for generating notifications on a mobile device when a tracking device is left behind. The method involves accessing historical signal strength information related to tracking device behavior, receiving signals from the tracking device, and comparing the received signal strengths with expected values based on historical data. If a discrepancy is detected, the mobile device generates a notification to alert the user that the tracking device has been left behind. The notification can take various forms, such as a phone call, text message, or audio notification, providing flexibility in communication methods.

Additionally, the system includes a non-transitory computer-readable storage medium storing executable instructions and a hardware processor to perform the steps outlined in the method. The system allows for customization of expected signal strengths by the user or based on the time of day, enhancing the accuracy of the notifications. Furthermore, the mobile device can automatically inform a tracking system or configure the tracking device to operate in a lost mode when significant signal strength differences are detected, improving the overall tracking and retrieval process. Overall, the invention aims to prevent the loss of tracking devices by leveraging historical data and real-time signal strength analysis to provide timely notifications to users.
