System for reminding user to remove smartphone from vehicle when exiting

Abstract

A system for detecting a smart device left in vehicle. The system includes a capacitor, a first switch, and a second switch. The capacitor is configured to store energy generated by a voltage source configured to power vehicle accessories. The first switch is movable between an open position and a closed position. The first switch is configured to be in the open position when the voltage source is on, and in the closed position when the voltage source is off. A second switch is movable between an open position and a closed position. The second switch is configured to be in the open position when the smart device is not on a charging pad, and in the closed position when the smart device is on the charging pad. The system generates a notification that the smart device has been left on the charging pad when both the first and the second switches are in the closed position. The notification is powered by the capacitor.
