  • Patent number: 5640147
    Abstract: A method for remotely monitoring the activities of a minor or dependent child or adult, on command from a parent unit. The child unit contains a sensitive audio microphone to provide the holder of the parent unit the capability to periodically listen to activity in close proximity of the child unit, thereby offering the holder of the parent unit a measure of confidence in the state of well-being of the holder of the child unit. The preferred embodiment provides a means to transmit an alert signal from the child unit to the parent unit in the event of an emergency. The transmission media used to interconnect both units is wireless, and may comprise radio frequency or infrared optical means, or any combination thereof.
