Patent ID: 7346336

Claim:
A rescue device to be worn by a user and usable in combination with a remote mobile signal receiver for processing transmitted signals from a remote source, the rescue device serving to provide notice to others of the user being in trouble and to aid those others in locating the user, the rescue device comprising: a housing adapted to be carried by the user; a motion detector coupled to the user so as to monitor the motion of the user, said motion detector providing a motion detector signal indicative of any motion detected thereby; a transceiver in said housing, said transceiver having, a transmitter for transmitting a locating signal, the locating signal being configured to be trackable by the remote mobile signal receiver, a signal receiver configured for tracking locating signals transmitted from a remote source, a mode switch for selectively directing power either to said transmitter, placing said transceiver in a transmit mode, or to said signal receiver, placing said transceiver in a receive mode, and means for providing the user with output for instructing the user to move in a direction that will advance the user toward a remote source of transmitted locating signals when said transceiver is operating in the receive mode; and a control logic circuit for processing the motion detector signal, said control logic circuit interacting with said transceiver so as to facilitate the locating signal being transmitted by said transmitter in response to the motion detector signal when the motion detector signal indicates that no motion has occurred for a predetermined time interval.
