Decoding Reed-Solomon Codes

Improvements in a gas detecting system utilizing a filament-heated gas sensor displaying measurable resistance characteristics which vary with the concentration of selected gases within the atmosphere in the vicinity of the sensor inhibit the production of gas detection indications automatically during the initial activation of the system while the sensor element is stabilizing and further inhibit the production of short staccato alarm indications produced by inherent small changes in the characteristics of the sensor brought about by thermal drift.
