ABSTRACT:
A rescue device has a motion detector and a transceiver that either transmits a locating signal, which can be tracked by others, when worn by user and operated in a transmit mode or receives and tracks a locating signal transmitted by another transmitter when the device is operated by the user in a receive mode. A control logic circuit suppresses transmission of the locating signal unless a motion signal, generated by the motion detector responsive to the user's movement, indicates that the user has not moved for a predetermined time interval. Thus, the rescue device can transmit the locating signal when the user is motionless, providing notice that the user is immobile and aiding others in locating the user. When receiving, the device guides the user in locating the source of a transmitted locating signal to aid the user in locating an immobilized person or a building exit.
