Abstract:
1. An apparatus to detect the presence of a child in a vehicle, comprising: a monitoring assembly comprising a first processor, a pressure transducer in communication with said first processor, and a monitoring transmitter in communication with said first processor, wherein said pressure transducer provides a load signal to said first processor when said pressure transducer senses a load, wherein said load signal is proportionate in strength to a weight detected by pressure transducer, and wherein said first processor determines said detected weight using said load signal, and wherein said first processor causes said monitoring transmitter to emit an activation signal if said detected weight is equal to or greater than a threshold weight; a vehicle controller assembly comprising a second processor, a receiver in communication with said second processor, a transceiver in communication with said second processor, wherein when said receiver receives said activation signal provided by said monitoring transmitter, said transceiver provides RFID interrogation signals; a portable key fob comprising an RFID circuit, wherein said RFID circuit receives said RFID interrogation signals and provides response signals to said transceiver; wherein: if said transceiver receives a response signal from said key fob, said transceiver provides a heart beat signal to said second processor; if said transceiver does not receive a response signal from said key fob, said transceiver does not provide a heart beat signal to said second processor; if said receiver is receiving activation signals from said monitoring assembly, and if said second processor is not receiving heart beat signals from said transceiver, then said second processor causes an interconnected vehicle horn to beep, and interconnected vehicle head lights to flash.
