Abstract: A smoking article, such as a cigarette, includes a lighting end and a mouth end. The lighting end is a longitudinally extending segment comprising smokable material that is intended to be lit and burned, and the resulting smoke generated by the burning of that smokable material is intended to be drawn into the mouth of the smoker through the mouth end of smoking article. A mouth end piece is located at the mouth end of the smoking article, and the mouth end piece allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generation system that is located between the lighting end segment and the mouth end piece. The aerosol-generation system includes (i) a heat generation segment located adjacent to the lighting end segment, and (ii) an aerosol-generation region located between the heat generation segment and the mouth end piece. The aerosol-generation region incorporates an aerosol-forming material (e.g., glycerin and flavors).

Abstract: A grounding arrangement is disclosed for microelectronic control of operating devices such as solenoid operated sprinkler valves in an a-c sprinkler system wherein one a-c power line connecting the several valve solenoids is earth-grounded and d-c microelectronic control circuits use the voltage level of the non-grounded a-c power line as a common voltage reference to operate switch means which interruptively supply a-c power to the valve solenoids.
