  • Patent number: 5617074
    Abstract: A child finder basically consists of a transmitter which is concealingly attachable to a child's body and which sends a signal to a conventional receiver so that the child's location can be continually monitored. The transmitter will typically be carried in an article of jewelry, such as a watch, bracelet, ring, or the like, and will use a special on/off switch which allows the transmitter to be activated only when the jewelry is being worn by the child. The switch includes a reciprocal push button which closes the transmitter's electrical circuit when depressed, and the button is spring-biasedly moved away from electrical contact with the transmitter's circuit when the article of jewelry is not being worn.
