ABSTRACT:
The present invention is a battery powered, portable microprocessor based early warning alarming ashtray. It provides the smoker two different time limited unattended cigarette alarms, as well an alarm for a tipped ashtray; an alarm for a bumped ashtray; an alarm based on nearby or lower elevation smoke by either of the two smoke detection devices; and a low power alarm. It offers “full protection” for most of the likely scenarios encountered by smokers that could result in a fire. Emptying of the ashtray by tipping overrides and disables the tipping alarm momentarily. Since the apparatus is microprocessor controlled, the timing intervals and magnitude of the different alarm notifications can be preprogramed as well as the sensitivity of the smoke detector devices.
