    • An infant safety monitoring device that monitors a transmitters coded radio frequency (RF) signal mounted on an infants vehicle safety seat to a matched RF decoding receiver; that a vehicle driver would carry. This RF transmission and receiving system can operate between 902 and 928 MHz with 916 MHz being the norm, and will sound an audible alarm when the a driver has exceeded an approximate safe distance of 40 feet from their child. The system uses paired hardwired ID addressing to allow for low interfere and providing security with the coded narrow band signal. The coupled units provide monitoring and warning of excessive separation distances between a driver with the receiver and their child in their infant safety seat. The system will help prevent a child from being inadvertently left in a vehicle unattended while the driver strays away.
    • 一种婴儿安全监控装置,其将安装在婴儿车辆安全座椅上的发射器编码射频(RF)信号监视到匹配的RF解码接收机; 车司机会携带。 该射频发射和接收系统可以在902和928MHz之间工作,其中916MHz是常规,并且当驾驶员已经超过距离他们的孩子40英尺的大概安全距离时将发出声音报警。 该系统使用配对的硬连线ID寻址来允许低干扰并且为编码的窄带信号提供安全性。 耦合单元提供对接收器的驾驶员与他们的婴儿安全座椅中的孩子之间的过度间隔距离的监视和警告。 该系统将有助于防止一名小孩在驾驶员离开时被无意中留在车内无人值守。
