Patent ID: 10232821

Abstract:
A key ring transceiver module activates when a child has been left inside of a car seat when the corresponding buckle transceiver is out of range. The buckle transceiver system includes a weight sensor indicating that a child is inside of the baby seat, a pair of limit or indication switches indicating that a child is retrained within the baby seat, and a pair of PING/PONG sending and receiving radio pairs that communicate range of the baby buckle transceiver from the key ring transceiver. When the baby seat contains a child restrained within, and the transceiver moves out of range, a distress alarm/signal will be enabled on the transceiver to indicate that the baby is still confined to the restraints of the baby seat. The key ring transceiver will continue to signal a distress mechanism until the baby buckle transceiver trigger has been reset by removing the child from the car seat. Although several variations of the embodiment have been presented with similar computational schemes, this present embodiment contains the minimal number of necessary component for effective alerting, and fulfills several requirements of exception to previous system designs. Lastly most systems to date have incorporated elements of the vehicle, which can require OEM installation or absorbent aftermarket fabrication to the vehicle.
