Child in Vehicle Detector

A vehicle safety system comprising:

• a personal transmitter that periodically emits a radio frequency signal;
• an enclosure mounted within a passenger compartment of a vehicle;
• a receiver located within the enclosure, the receiver receiving and detecting the radio frequency signal;
• a movement detector located within the enclosure, the movement detector and enclosure are within a passenger compartment of the vehicle, the movement detector is contained within a partial Faraday shield, thereby reducing emissions and reception of signals from outside of the passenger compartment of the vehicle;
• the receiver attempts to detect the radio frequency signal for a period of time and, responsive to the personal transmitter being at a distance of at least five feet from the vehicle, the receiver does not detect the radio frequency signal for the period of time and then, responsive to such, the movement detector is operated to determine if there is movement within the vehicle;
• and
• if the movement detector detects a movement within the vehicle, an alarm is signaled.

A method of vehicle safety comprising:

• (a) within a vehicle, attempting to receive a radio frequency signal from a personal transmitter;
• (b) upon not receiving the radio frequency signal for a predetermined period of time, indicative that the personal transmitter is further away from the vehicle by a distance of between five and ten feet:
• (c) determining if there is movement within the vehicle using an impulse radar transceiver mounted within a partial Faraday shield, the partial Faraday shield reducing emission to an area outside of the vehicle and, therefore, reducing false alarms;
• (d) if there is movement within the vehicle, sounding an alarm;
• (e) waiting until a reset is received;
• (f) stopping of the sounding of the alarm;
• and
• (g) repeating steps (a)-(f).
