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.

Independent Claims | See all claims (25)

  1. 1. An apparatus and controlling circuitry for periodically operating an aerosol container at discrete dispensing intervals to disperse a discrete quantity of the aerosol contents thereof, including powered means for periodically actuating an aerosol dispensing means of said container, said circuitry controlling said powered means for a predetermined number of actuations, and first warning means for indicating the probable total evacuation of container contents and the necessity for termination of said dispensing operation when the actuation count reaches said predetermined number, and further including mode switching means for setting said circuitry into a plurality of different operating modes, said plurality of different operating modes comprising at least three modes, including a continuous intermittent operation, a controlled daytime operation, and a controlled night operation.
  2. 15. An apparatus and controlling circuitry for periodically operating an aerosol container at discrete dispensing intervals to disperse a discrete quantity of the aerosol contents thereof, including powered means for periodically actuating an aerosol dispensing means of said container, said circuitry controlling said powered means for a predetermined number of actuations and including means counting the actuations, and first energizing means coupled to first warning means for energizing said first warning means when the actuation count reaches said predetermined number to thereby indicate the probable total evacuation of container contents and the necessity for termination of said dispensing operation, and further including mode switching means for setting said circuitry into a plurality of different operating modes, said plurality of different operating modes comprising at least three modes, including a continuous intermittent operation, a controlled daytime operation, and a controlled night operation.
  3. 21. An apparatus and controlling circuitry for periodically operating an aerosol container at discrete dispensing intervals to disperse a discrete quantity of the aerosol contents thereof, including powered means for periodically actuating an aerosol dispensing means of said container, said circuitry including means counting the actuations of said powered means for a predetermined number of actuations, and first energizing means coupled to first warning means for energizing said first warning means when the actuation count reaches said predetermined number to thereby indicate the probable total evacuation of container contents and the necessity for termination of said dispensing operation, and further including mode switching means for setting said circuitry into a plurality of different operating modes, said plurality of different operating modes comprising at least three modes, including a continuous intermittent operation, a controlled daytime operation, and a controlled night operation.
