ABSTRACT:
A vehicle safety system includes independently operable child location determining mechanism that has a sound wave emitting module nested therein and care giver location determining mechanism for determining a location of the care giver. The care giver location determining mechanism includes a housing that fits on a key ring, a processor including a memory, a speaker coupled to the processor, a power supply source coupled to the speaker and the processor, and a receiver for communicating with the sound emitting module. The memory includes software instructions causing the system to perform the steps of generating and transmitting a first RF signal to the child location determining mechanism, and generating and transmitting a second RF signal to the child location determining mechanism. The first and second signals are responsive to the care giver location determining mechanism when the care giver moves beyond the predetermined distance from the child location determining mechanism.
