USER-GUIDED SYSTEMS AND METHODS FOR ALIGNING A CHARGER WITH A RECHARGEABLE DEVICE

A wireless charging system and associated methods are provided to assist a user with manually aligning a wireless charger with an implantable device, such as an implantable medical device (“IMD”). Both the charger and the IMD are equipped with at least one inertial sensor (e.g., an accelerometer, a gyroscope, or a magnetometer). Data from these sensors is wirelessly sent to a controller, which processes the information to generate three-dimensional (3-D) digital models (also known as “digital twins”) of the charger and IMD on a graphical user interface, showing their relative position and orientation in real-time. During alignment, a patient initially positions the charger near the IMD. The digital twins are displayed to the patient as visual aids, helping the patient manually adjust the charger into parallel and axial alignment with the IMD quickly and precisely, thereby enhancing user experience and wireless charging efficiency.
