A method of controlling a hot wire anemometer (HWA) of a nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

A method of controlling a hot wire anemometer (HWA) of a non-nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the non-nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the non-nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the non-nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

The e-vaping method includes providing a reservoir within a housing, the reservoir being configured to contain a pre-vapor formulation, first configuring ejectors to eject droplets of the pre-vapor formulation towards a vaporizing heater, the ejectors being in fluid communication with the reservoir, and second configuring a vaporizing heater to vaporize at least some of the droplets.

Electronic vaping device

An e-vapor apparatus may include a pod assembly including a pre-vapor formulation compartment, a first electrical connector, a vapor channel traversing the pre-vapor formulation compartment, and a vaporizer, the pre-vapor formulation compartment configured to hold a pre-vapor formulation therein and in fluidic communication with the vaporizer during an operation of the e-vapor apparatus, the first electrical connector including first and second power electrodes, the first power electrode including a first contact portion on an exterior of the first electrical connector and a first extended portion configured to contact an anode portion of the vaporizer, the second power electrode including a second contact portion on the exterior of the first electrical connector and a second extended portion configured to contact a cathode portion of the vaporizer. The e-vapor apparatus may further include a dispensing body including a second electrical connector configured to connect to the first electrical connector.

Pod assembly and e-vapor apparatus including the same

A vapor cartridge for a non-combustible vaping device may be configured to receive a flavor cartridge, generate a vapor, and direct the generated vapor through the flavor cartridge to provide a flavored vapor. The flavor cartridge may include an instance of electrically conductive material extending at least partially around the flavor cartridge. The vapor cartridge may include an authentication assembly including a set of electrically conductive instruments may independently and directly contact the instance of electrically conductive material of the flavor cartridge inserted into the vapor cartridge, such that the electrically conductive instruments are electrically connected to each other through the instance of electrically conductive material of the flavor cartridge. The vapor cartridge may be coupled with a base that includes a control circuitry configured to control vapor generation by the vapor generator, based on the electrically conductive instruments being electrically connected to each other through the flavor cartridge.

Non-combustible vaping device

The e-vaping device includes a housing, a vaporizing heater within the housing, and a reservoir configured to contain a pre-vapor formulation. At least one ejector is in fluid communication with the reservoir. The at least one ejector is configured to eject droplets of the pre-vapor formulation towards the vaporizing heater. The vaporizing heater is configured to vaporize at least some of the droplets. The method operates the e-vaping device.

The e-vaping device includes a housing, and a vaporizing heater within the housing. A cartridge within the device defines a reservoir containing a pre-vapor formulation. A chip on an end of the cartridge defines a via in fluid communication with the reservoir. The chip includes an ejector in fluid communication with the via, where the ejector is configured to eject droplets of the pre-vapor formulation towards the vaporizing heater. The method of making the device includes connecting a chip to an end of the cartridge, where the ejector ejects droplets of the pre-vapor formulation towards the vaporizing heater. The method of operating the device includes supplying a first electrical current to the vaporizing heater to energize the vaporizing heater and supplying a second electrical current to the ejector to energize the ejector and eject droplets of a pre-vapor formulation from the ejector towards the vaporizing heater.
