Abstract
An electronic cigarette comprises a battery portion which is operable to provide power to a heating element of the electronic cigarette, and a cartomizer coupled with the battery portion. The cartomizer comprises a liquid container which provides a liquid toward the heating element wherein the liquid is used for producing and flavoring a vapor of the electronic cigarette when the liquid is heated by the heating element, and a memory which is operable to record and store an amount of the liquid remaining in the liquid container.
Claims16
An electronic vaping device comprising:
- a pre-vapor formulation reservoir configured to retain a pre-vapor formulation;
- a heating element configured to heat pre-vapor formulation drawn from the pre-vapor formulation reservoir;
- a capacitor connected in parallel with the heating element, the capacitor configured to be charged by power applied to the heating element;
- a memory connected in parallel with the heating element and the capacitor, the memory configured to
- receive a supply voltage from the power applied to the heating element when the power is applied to the heating element,
- receive a supply voltage from the capacitor when the power is not applied to the heating element, and
- store a first amount of power provided to the heating element over time;
- and
- processing circuitry configured to
- calculate an aggregate amount of power provided to the heating element over time by adding a second amount of power provided to the heating element over time to the first amount of power provided to the heating element over time, and
- predict complete depletion of the pre-vapor formulation in the pre-vapor formulation reservoir based on the aggregate amount of power.
