Abstract: A position indicator device for marking the location of an aircraft that has crashed has a buoyant housing containing a radio beacon, a dye dispenser, and a visual beacon. Upon the crash of the aircraft, the buoyant housing is deployed by an air bag ejection system. Upon deployment, a control wire pulls a control pin from a controller, thereby activating the radio beacon, dye dispenser, and visual beacon. The radio beacon immediately alerts emergency personnel that a crash has occurred and can guide the emergency personnel to the scene. The dye dispenser slowly releases a liquid dye that stains the water an easily recognizable color. The visual beacon not only allows crash survivors to find the position indicator device and gather together for survival and rescue, it also allows emergency personnel to find the position indicator device in bad weather or at night.

Abstract: In order to more fully support the need to interconnect dissimilar networks, methods and apparatus are set forth which allow a transport gateway between a native (SNA/APPN) network and a mixed or non-native network to preserve the dynamic functions of the native network. The functions of fully dynamic directory and route selection are supported, in addition to the ability to use parallel gateways when connecting a native network to a mixed network. The ability to route information through a gateway from a dependent LU requester in a non-native network to a dependent LU server in a SNA/APPN network is also demonstrated. This allows concatenation of native and non-native networks while maintaining the addressability and accessibility of the native network.
