Abstract: The fire suppression system includes a system piping, with at least one sprinkler, a flow control valve, a fire suppressant delivery line in fluid communication with the flow control valve, at least one fire detector adapted to detect temperatures associated with fire, and a control system. The control system is in communication with the fire detector, the flow control valve and the system piping. The control system is adapted to detect a flow condition and a no-flow condition in the system piping and actuates the flow control valve between a normally open condition and a closed condition when the fire detector is in a no-fire condition state and the control system detects a flow condition in the piping system and may cycle the flow control valve to open when the flow control valve is closed in response to the fire detector being in a fire condition state.

Abstract: A mercury-cadmium-telluride (HgCdTe) epitaxial detector array is formed on a cadmium telluride (CdTe) substrate. Connecting leads to the detectors are a molybdenum layer covered by a gold-germanium layer. These leads have excellent matches for the thermal coefficients of expansion of the HgCdTe and CdTe and provide ohmic contacts such that the D* of the array is greater than that of arrays made by prior processes using known lead materials, and the noise level is reduced by a factor of approximately three.

Abstract: A retina is provided for a pyroelectric vidicon which is rugged, long liv and has increased resistance to contamination by normal environments encountered during testing and subsequent installation in the vidicon tube.

Abstract: A method of fabricating a retina and mounting it in a pyroelectric vidicon s provided wherein the pyroelectric material is polished, etched and coated with metal on one broad side and with a dielectric layer on the opposite (electron beam) side.
