Abstract
Abstract A small device carried or worn by a person emits a warning at predetermined intervals. Unless the person actuates a reset control within a short period of time, the device transmits a radio signal to a base unit that dials one or more predetermined telephone numbers and plays back a prerecorded message. The system is particularly useful for elderly persons or those with health problems where it may not be possible for the person to physically reach the base unit. In addition, means for actuating the transmitter at any time are provided.
