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.

Abstract: An insert sleeve for use in the firing system of a muzzle loading gun wherein the insert sleeve has a bore operably connecting the atmosphere to the bore of the gun barrel and having a conventional firing member operatively associated with the outer end of such insert sleeve. A nipple formed from a heat resisting metal is positioned in the sleeve at the inner end thereof and has a smaller diameter center portion than any other portion of the bore of the sleeve to form the limiting size connector opening from the firing means to the muzzle loader bore of the gun barrel.
