  • Patent number: 5647052
    Abstract: A volatile substance dispenser is provided which provides an indication of the dissipation of a quantity of volatile substance by changing an electrical signal level after a time duration corresponding to an expected period time for the quantity of volatile substance to disseminate. A heat source causes the volatile substance to disseminate into the atmosphere. Dissipation of the volatile substance is indicated. For example, dissipation may be indicated by a light bulb burning out where the light bulb is a limited duration bulb with a lifetime that corresponds to the quantity of volatile substance. The dispenser may be disposable and may also serve as a night light.
