Abstract

Apparatuses, including systems and devices (“vaporizers”), for vaporizing material to form an inhalable aerosol that include capacitive lips sensing to regulate the temperature of the vaporizer, including transiently boosting the temperature. Methods of operating a vaporizer having a capacitive lip sensor are also described.

Claim(s)

1. An apparatus comprising: a reservoir configured to hold a vaporizable material; a heater configured to heat the vaporizable material; a mouthpiece in communication with the reservoir; a capacitive sensor configured to output capacitance readings, wherein the capacitive sensor comprises a flexible circuit onto which a conductive region is layered; and a controller configured to perform operations comprising: regulating a temperature of the heater to a preselected temperature; obtaining the capacitance readings from the capacitive sensor; determining a baseline capacitance based on more than one of the capacitance readings; determining a value based on a difference between a first capacitance reading of the capacitance readings and the baseline capacitance; and increasing the temperature of the heater based on the value being at or above a threshold.;
19. An apparatus comprising: a reservoir configured to hold a vaporizable material; a heater configured to heat the vaporizable material; a mouthpiece in communication with the reservoir; a capacitive sensor configured to output capacitance readings, wherein the capacitive sensor comprises a flexible circuit onto which a conductive region is layered; and a controller configured to perform operations comprising: regulating a temperature of the heater to a first temperature; obtaining the capacitance readings from the capacitive sensor; determining a baseline capacitance based on more than one of the capacitance readings; determining a value based on a difference between a first capacitance reading of the capacitance readings and the baseline capacitance; and reducing the temperature of the heater to a second temperature that is lower than the first temperature when the value is at or below a threshold for a first predetermined period of time.;
34. An apparatus comprising: a reservoir configured to hold a vaporizable material; a heater configured to heat the vaporizable material; a mouthpiece in communication with the reservoir; a capacitive sensor configured to output capacitance readings; and a controller configured to perform operations comprising: regulating a temperature of the heater to a first temperature; obtaining the capacitance readings from the capacitive sensor; determining a baseline capacitance based on more than one of the capacitance readings; determining a value based on a difference between a first capacitance reading of the capacitance readings and the baseline capacitance; reducing the temperature of the heater to a second temperature that is lower than the first temperature when the value is at or below a threshold for a first predetermined period of time; and reducing, when the value remains below the threshold for a second predetermined period of time, the temperature of the heater to a third temperature that is lower than the first temperature and lower than the second temperature.
