Abstract: A control device of an aerosol generating device includes a main control unit, and is connectable to a battery and a heater coil. The main control unit is configured to carry out one or more execution loops, a first execution loop includes applying a first power output to the heater coil for a first number of steps, disabling the first power output and thereby switching off the heater coil in a second number of steps, measuring a first heater coil voltage of the heater coil in a third number of steps, pausing with the heater coil switched off for a fourth number of steps, and measuring a first off-load battery voltage of the battery in a fifth number of steps. The main control unit is further configured to calculate an updated power output based upon the first heater coil voltage and first off-load battery voltage.

Abstract: A cartridge for releasable connection to an electronic cigarette includes a substance to be vaporized and is provided with an electrical circuitry, wherein the electrical circuitry includes circuit terminals configured to engage with circuit connectors located on a main body of the electronic cigarette and configured to establish a data connection between the cartridge and the main body, a memory for storing data, and wherein the circuit terminals of the cartridge are located on a housing of the cartridge, and one or more of the plurality of circuit terminals, or at least initial connection portions thereof, are provided at different positions in the longitudinal direction of the cartridge relative to the longitudinal positions of the circuit connectors, or at least initial connection portions thereof.

Abstract: A cartridge for a personal vaporizing device includes a liquid store, a liquid transfer element, a heating element, a first power terminal and a second power terminal connected to the heating element, and a memory configured to store a first reference value indicating the resistance of the heating element at a reference temperature or reference. A method of manufacturing such a cartridge is also provided. A main body of a personal vaporizing device has a cartridge seating configured to receive such a cartridge.
