  • Patent number: 12156536
    Abstract: A vaporizer device may include a controller and a heater control circuitry. The controller may generate, based at least on a temperature of a heating coil in a cartridge coupled with the vaporizer device, an output signal for controlling a discharge of a battery of the vaporizer device. The battery may be discharged to the heating coil to increase the temperature of the heating coil and cause a vaporization of a vaporizable material contained in the cartridge. The heater control circuitry may determine the temperature of the heating coil. The heater control circuitry may further control, based on the output signal from the controller, the discharge of the battery to the heating coil. The heater control circuitry may be powered by a voltage rail coupled to a voltage regulator configured to regulate an output voltage of the battery.

  • Patent number: 12102117
    Abstract: A vaporizer device may include a pressure sensor and an ambient pressure sensor. The pressure sensor may be configured to measure a first pressure in an air flow path in the vaporizer device. The ambient pressure sensor may be configured to measure a second pressure corresponding to an atmospheric pressure. The vaporizer device may further include a controller. The controller may be configured to transition the vaporizer device to a first standby mode when the first pressure is equal to or greater than the second pressure for a first threshold quantity of time. While the vaporizer device is in the first standby mode, the controller may be further configured to transition the vaporizer device to a second standby mode when the second pressure is a threshold quantity greater than the first pressure and no motion event is detected for a second threshold quantity of time.

The element submount includes a substrate, a first conductive heat-dissipating layer, a second conductive heat-dissipating layer, a first heat-dissipating layer and an element bonding layer. The substrate has opposite first and second surfaces. The first conductive heat-dissipating layer is formed on the first surface. The second conductive heat-dissipating layer is formed on the first surface and separated from the first conductive heat-dissipating layer. The first heat-dissipating layer is formed on the second surface. The element bonding layer is formed on the second conductive heat-dissipating layer. By electroplating and processing techniques, the edge of one or two sides of the element bonding layer exceeds an edge of the second conductive heat-dissipating layer and partially covers a side of the second conductive heat-dissipating layer.
