Abstract
An alert system detects the presence of occupants in a vehicle using optical sensors comprised of (infrared) emitters and photodetectors. Each sensor emits a beam across a path in proximity to a seat. Retroreflectors are positioned in the path. A seated occupant blocks the path and prevents reflection. If the path adjacent to a baby's seat is blocked and the path adjacent to the driver's seat is not blocked, an alarm event is triggered. After a delay, voice and text messages and audible and visible output are generated.
