Abstract
Abstract An apparatus and controlling circuitry for periodically operating an aerosol container in discrete dispensing intervals to disperse a discrete quantity of the contents thereof. The apparatus includes a powered mechanism for actuating the aerosol, with the circuitry controlling the powered mechanism for a predetermined number of actuations. An energizing means activates a warning mechanism when the actuation count reaches the predetermined number to thereby indicate the probable total evacuation of the aerosol container and the necessity for termination of the operation. The apparatus also includes means for setting the circuitry into a plurality of different operating modes, including a continuous intermittent operation, a controlled daytime operation, and a controlled night operation. The apparatus may be battery operated, and it then includes a second warning mechanism for indicating whether the battery power is sufficient to operate the powered mechanism.
