Patent ID: 7012522

Claim:
A child monitoring system for monitoring a distance of a child around an supervising adult, the child monitoring system comprising: an adult assembly transmitting a monitoring signal over freespace, said adult assembly being adapted for being worn by the adult; and at least one child assembly receiving said monitoring signal such that said child assembly produces an alarm sound when said child assembly detects that said monitoring signal is traveling over a distance greater than a pre-determined safe distance, said child assembly being adapted for being worn by the child such that said alarm sound emitted by said child assembly alerts others that the child has ventured to far away from the supervising adult; said adult assembly comprising an adult processing assembly and transmitter, said transmitter being operationally coupled to said adult processing assembly such that said adult processing assembly generates said monitoring signal and said transmitter transmits said monitoring signal over freespace; said child assembly comprising a child processing assembly and a receiver, said receiver being operationally coupled to said child processing assembly such that said receiver receives said monitoring signal transmitted by said transmitter of said adult assembly, said child processing assembly calculating the distance said monitoring signal traveled to be received by said receiver of said child assembly such that said child assembly emits the alarm sound when said child processing assembly calculates that said monitoring signal has traveled a distance greater than said predetermined safe distance.
