Optical smoke detectors depend on light scattering properties and complex algorithms to determine the presence of smoke. A large body of knowledge and many products in the market today include wavelength dependent scattering, which utilize the optical properties of particulates to discriminate smoke. Yet, smoke detector design and evaluation lacks a modelbased approach to extend scattering prop...

Reliability has vital significance to engineers and designers in a safety system. Consequently, failures free operation of components or sub-systems is of their key concern. To assess the reliability of such systems quantitatively, failure data of the components or sub-systems is essentially required. In general, such data is either not pre-recorded or present in linguistic form (good, bad etc)...

This experiment analyzes the tendency of fire detection through combustion products generated during UL 268 wood flame fires and smoldering tests. Fire was measured using a particle matter sencor (PMS), gas analyzer (CGA), (GA). The were matched analyzed at 5 %/m (non-operation), 10 %/m, 15 smoke sensitivity by detector. In case flaming fire, PMS PM 10, CGA CO, SO2, GA HCHO, TVOC, trend observe...

U.S. Government work not protected by U.S. copyright. IEEE AC paper #1522. Abstract— Airborne trials have produced the first applications of a new thermal-imaging radiometer, the FireMapper, which is a unique three-channel, calibrated imaging system designed through a Research Joint Venture between the USDA Forest Service and Space Instruments, Inc. FireMapper has been designed to map the progr...
