  • Patent number: 11957167
    Abstract: Provided is a cartridge assembly for containment of a vaporizable substance to be used in an electronic vaporizer device. The cartridge assembly includes a cartridge and a susceptor element. The cartridge includes a base section and a side section coupled to the base section at a first end of the side section. An aperture is defined at a second end of the side section and the side section includes at least two apertures located in the side section, where the at least two apertures are configured to allow air to flow into an interior chamber of the cartridge when air flows out of the aperture defined at the second end. The susceptor element is located within the cartridge.
    Type: Grant

  • Patent number: 11700674
    Abstract: Provided is a system for sensing temperature in an induction heating system. The system includes an induction element, a susceptor element, and a temperature sensor circuit in thermal contact with the susceptor element. The temperature sensor circuit includes a capacitor having a capacitance value equal to C and an inductor having an inductance value equal to L. A resonant frequency of the temperature sensor circuit changes based on a temperature of the susceptor element and the induction element is electromagnetically coupled to the temperature sensor. The resonant frequency of the temperature sensor circuit is equal to ½??LC.

  • Publication number: 20220225475
    Abstract: Provided is a system for determining a characteristic of a susceptor element that may be associated with a vaporizer device. The system includes an inductor element and a control device. The control device is configured to detect a magnetic field associated with the inductor element and determine a characteristic of a susceptor element based on the magnetic field. A method and computer program product are also disclosed.
