SYSTEM AND METHOD FOR MEASURING PAYLOAD DOSAGE IN A VAPORIZATION DEVICE

Abstract:

The present invention is directed to a vape device configured to determine the dose of a payload delivered to a user during each of a plurality of user inhalations. In a first embodiment, the vape device tracks the energy used to vaporize a portion of the payload during user inhalation to determine the dose. In a second embodiment, the vape device measures the temperature at multiple locations within the air flow chamber during user inhalation to determine the dose. In a third embodiment, the vape device measures the intensity of light that is transmitted through the vaporized payload, reflected off the vaporized payload, or transmitted through a light transmitting medium positioned within the vaporized payload, during user inhalation to determine the dose. In a fourth embodiment, the vape device utilizes hot wire anemometers to determine the mass of the vaporized payload that was delivered to the user during each user inhalation and/or to determine the size and density distribution of the droplets in the vaporized payload and use such distribution to calculate the total mass of the vaporized payload that was delivered to the user during each user inhalation. The disclosed methods may be used independently, or in any combination, in accordance with the invention.
