Abstract: A multiplexer system for combining the signals from a multitude of spatia distributed sensors in a multi-sensor array. The system includes the fundamental features of combining signals from the spatially distributed sensors into a single composite signal, transmitting the composite signal to a receiving station, and decomposing it into its components in a demultiplexer at the receiving station.

Abstract: A remote elevated platform (REP) for positioning a payload from an aircraft nd maintaining its position unattended, comprises a lifting body, a payload designed to be suspended from the lifting body, a tether line and a mooring system. The platform is dropped from the aircraft and the lifting body is deployed by opening it up by means of a static line or a barometric device. The mooring system is then released and it starts falling freely but attached to the tether line. The mooring line then strikes the surface and fixes itself in the ground. In a body of water, a float and sea anchor is deployed instead.
