Claim 18:
19. A vaporization device for delivering vaporized material for inhalation by a user, the vaporization device comprising:
an air intake through which air enters the vaporization device during an inhalation event;
an outlet through which vapor is withdrawn from the vaporization device during the inhalation event;
a vaporization chamber for receiving material to be vaporized;
a heater positioned between the air intake and the vaporization chamber, and upstream of the vaporization chamber with respect to a flow of the air through the vaporization device durating the inhalation event, and operable to heat the air which passes through the heater during the inhalation event as the air moves from the air intake toward the outlet;
a temperature sensor positioned downstream of the heater with respect to the flow of the air through the vaporization device durating the inhalation event and operable to sense a temperature of the air downstream of the heater;
a control system operatively coupled to the temperature sensor to provide a closed loop control for maintaining a temperature of the air delivered to the vaporization chamber at, or within a predetermined tolerance of, a desired vaporization temperature for at least a majority of a duration of the inhalation event;
a vaporization head positioned downstream of the heater with respect to the flow of the air, the vaporization head being removably coupled to a base assembly, the base assembly including the temperature sensor, the control system and a power source disposed within a housing, wherein the vaporization head includes a heat exchanger within a removable mouthpiece, the vaporization chamber defined at least in part by the heat exchanger; and
a vapor concentration measurement device operatively coupled to the control system to detect the vapor concentration, the vapor concentration measurement device comprising:
a light source positioned at one end of the vaporization chamber; and
one or more sensors positioned at other end of the vaporization chamber, a first sensor of the one or more sensors being configured to measure a change in an amount of light from the light source reaching the first sensor.
