Abstract: A fire suppression system adapted for use in a lavatory of an aircraft. The system includes a supply coupled to one or more fluid discharge nozzles via one or more fluid flow lines. A pressure source in communication with the fluid flow lines provides pressure to assist in supplying a pressurized flow of fluid through the flow line(s) to the nozzles(s). Furthermore, the system is capable of using the potable water supply of the aircraft or it can be self-contained with its own water supply reservoir. If self-contained, the system includes a pressurized fluid source to assist in supplying water to the discharge nozzle(s).

A pressure source in communication with the fluid flow lines provides pressure to assist in supplying a pressurized flow of fluid through the flow line(s) to the nozzles(s). The fire suppression system creates a spray of water capable of suppressing fires within a waste container area or within the entire lavatory area. Heat sensitive valves enable the system to automatically detect the start of a fire. Furthermore, the system is capable of using the potable water supply of the aircraft or it can be self-contained with its own water supply reservoir. If self-contained, the system includes a pressurized fluid source to assist in supplying water to the discharge nozzle(s).

Abstract: A sense amplifier and sensing scheme for sensing the normal or blown condition of fuses in a programmable read only memory (PROM) or similar device. A sensing circuit is provided with a threshold level separating high and low input levels indicative of the fuse condition. The sensing circuit has one circuit branch with a first current mirror with a temperature characteristic which provides a threshold level which is slightly divergent with reference to a low level input. Another circuit branch clamps the high input level to the slightly divergent threshold level and uses a second current mirror with a temperature characteristic which provides a high level slightly more divergent than the threshold level. By selecting mirror currents proportionally, high level and threshold level temperature characteristic divergence can be proportionally controlled in selected amounts with respect to the low level.
