Story Behind the Invention

Inventor Lors developed this clever innovation, which is an apparatus that prevents children from being left behind on school buses. The system utilizes an electronic card system in which each child would have their own personal card. As the child enters the bus, the card would be given to the bus driver who would place the card within a slot of a corresponding control panel, thus recording the child's seat location and the presence of that child. When the child exits the bus, the card would be removed and returned to the child. Following a preset time interval, a warning light and buzzer would be activated if the seat remains occupied, alerting the bus driver to check the seat location. Every bus seat would have an integral weight sensor connected to the control panel. An alternative embodiment would provide the bus driver, or an assigned chaperone, a pushbutton selection array corresponding to the seat assignments. In such a manner, no child would ever be left on a bus to become trapped in a storage lot overnight. The use of the Seat Occupancy Sensor for Motor Vehicles effectively protects students from being left on school buses, thus ensuring their safety.
