A sensor system for detecting jarring, acceleration or other application of force to a firearm, andor movement of the firearm into an undesired orientation, which includes a sensor array mounted to a firearm. The increase in yield and selectivity for CO and H2 products results at least in part from the substitution of H2S partial oxidation to elemental sulfur and water for the combustion of light hydrocarbon to CO2 and water. The apparatus has a support platform, a storage unit and a base for transporting two rolls of material simultaneously to the front of the apparatus. Additional layers can be epitactically grown. The audio data stored in the memory is supplied for playback.
