  • Method and apparatus for generating a volatilized liquid
    Patent number: 7400940
    Abstract: A programmable aerosol generator forms a volatilized liquid by supplying a material in liquid form to a flow passage and heating the flow passage, such that the material volatilizes and expands out of an outlet of the channel. The volatilized material, if desired, mixes with ambient air such that volatilized material condenses to form the aerosol. An apparatus and method for generating such a volatilized liquid, as well as the control and methods of heating, are disclosed as an analytical tool useful for experimental use, a tool useful for production of commercial products or an inhaler device.
    Type: Grant

  • Aerosol generator having inductive heater and method of use thereof
    Patent number: 6681998
    Abstract: An aerosol generator includes an induction heating arrangement to vaporize fluid contained in a fluid passage. The vapor is then expelled from the fluid passage into the air creating a mist that forms the aerosol. The aerosol generator includes an excitation coil that inductively heats a heating element which transfers heat to the fluid in the fluid passage. The fluid passage can be located in a metal tube which can be removably mounted in the aerosol generator.
