AN ALARM SYSTEM FOR ALERTING A DRIVER TO THE PRESENCE OF AN ABANDONED LIVING BODY IN A VEHICLE

摘要

A system for alerting a driver to the presence of a living body such as, e.g., a baby, left alone in a vehicle. The system is based on sensors made in the form of optical waveguides, each connected to the surface of the driver's seat and a second seat, respectively. The second seat may be, for example, a child's seat. The optical waveguides serve as reliable movement sensors, as they are adapted to react to changes and movements in their immediate physical environment by affecting the intensity of the light traveling through them. By comparing the light intensities coming from both waveguides and checking it according to a predefined threshold, the system may detect situations where, for example, the driver left the vehicle yet a child has been left alone in it, and subsequently set on the alarm as a result thereof.
