A small unmanned air vehicle system having autonomous electrical energy transmission line docking capability and especially usable in military or other surveillance situations. Transmission line field sensing by the small unmanned air vehicle is used as an addition to global position system and other navigation methods and is especially applied to vehicle docking maneuvers. A plurality of vehicle carried electromagnetic fields-responsive sensors provides transmission line based signals to the vehicle guidance system in both far field and near field environments. Surveillance sensors are included in the vehicle payload. Vehicle battery charging energy procurement from the transmission line docking is included. Related commonly assigned patent documents are identified.

An fire protection system for use in shipboard magazines wherein electric at detectors in a ship magazine provide temperature data to a fire panel. Upon detection of predetermined threshold temperatures, the fire panel initiates an alarm system and activates a fire sprinkler valve to apply water to fire sprinklers in the magazine. Temperature data from the heat sensors and stored weapon response data are used by a damage control system to generate graphic display data showing thermal conditions in the magazine and estimated times and temperatures at which stored munitions will undergo thermal destruction.

A system for determining the time between the receipt of two different sils, includes a voltage ramp generator which generates a time dependent voltage signal upon receipt of a timing pulse at a time T.sub.1, and provides the instantaneous value of the voltage signal when the voltage ramp generator receives an input signal having a predetermined threshold value at time T.sub.2. A data processor coupled to receive the voltage signal, generates the timing pulse, and determines a time difference .DELTA.T from the voltage signal, where .DELTA.T=T.sub.2 -T.sub.1.

An electronic circuit architecture time-division-multiplexes analog sensor ignals from a distributed sensor array onto a common transmission line in a digitally encoded format. The architecture synchronizes the multiplexing, sampling and encoding to ensure a proper settling of the analog data signals and is fabricated to be compact with low power consumption for a cost-effective implementation for a number of sensors.
