US Patent 10131318 Child safety in a vehicle alert system and method

An alert system to assist in child safety in a vehicle includes a seat belt buckle insert adapted to be inserted between the male and female parts of a standard safety belt found in most automobiles or for a child car safety seat. It may also include a portable receiver device designed to be carried by a vehicle operator. The seat belt buckle insert detects whether the seat belt has been buckled and the temperature is within an acceptable range, as well as the approximate distance between the seat belt buckle insert and portable receiver device. The seat belt buckle transmits information gathered to the portable receiver device and triggers alerts notifying the vehicle operator of a child's safety status.
