  • Patent number: 5289163
    Abstract: A child position monitoring device monitors the position of a child by detecting the signal strength of a radio frequency carrier from a transmitter attached to the child. If the signal of the radio frequency carrier is to weak, the child is to far away from the adult who has the child position monitoring device. When this happens, the adult is informed that the child has wandered to far away through the use on an audio tone or through the use of vibrations coming from the device. Once the adult is notified that the child is too far away, the device also has a locating display for indicating the relative direction of the child with respect to the adult. The display uses eight LEDs arranged around an emblem used to represent the position of the adult. The LED which lights up indicates the relative direction of the child.
