Publication number: 20210007406Abstract: A response procedure for an aerosol-generating device includes detecting a fall or shock using at least one acceleration value and initiating at least one response procedure using a controller. Acceleration values are provided by at least one accelerometer coupled to the aerosol-generating device. The response procedures may include at least one of: initiating a mechanical change in the aerosol-generating device, initiating a modification to an external device interface, generating a human-perceptible beacon, storing data associated with the fall or shock in persistent or non-volatile memory, initiating a diagnostic routine, monitoring for a lost device condition, and initiating a soft shutdown or restart.Type: ApplicationFiled: March 28, 2019Publication date: January 14, 2021Inventors: Michel Bessant, Guillaume Colotte, Jennifer Ernestine Emma Plun

Patent number: 10876879Abstract: A aerosol-generating system includes a liquid storage portion, a liquid pressure sensor within the liquid storage portion, and a control unit that is in communication with the pressure sensor. The aerosol-generating system further includes an atmospheric pressure sensor in communication with the control unit. The atmospheric pressure sensor is configured to sense the atmospheric pressure of the environment. The control unit is configured to receive the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor. The control unit is further configured to determine the fill level of the liquid aerosol-forming substrate based on a comparison of the pressure signals from the liquid pressure sensor and the atmospheric pressure sensor.Type: GrantFiled: April 6, 2018Date of Patent: December 29, 2020Assignee: Altria Client Services LLCInventors: Guillaume Colotte, Stephane Bilat

Publication number: 20200196665Abstract: An aerosol-generating article may comprise a liquid storage portion containing a liquid aerosol-forming substrate, and a hydrochromic material provided on the liquid storage portion. The hydrochromic material has a first colour when in the presence of or when in contact with the liquid aerosol-forming substrate and a second colour when in the absence of or when not in contact with the liquid aerosol-forming substrate. An aerosol-generating system may comprise the aerosol-generating article, an aerosol-generating element, and an aerosol-generating device. An aerosol-generating device may comprise an electrical power supply, an electronic photosensor, and a controller configured to control a supply of electrical power from the electrical power supply based on a value of an optical property sensed with the electronic photosensor.Type: ApplicationFiled: March 3, 2020Publication date: June 25, 2020Applicant: Altria Client Services LLCInventors: Stephane BILAT, Guillaume COLOTTE

Publication number: 20200138108Abstract: An electrically operated aerosol-generating system may be configured to detect adverse conditions (e.g., a dry heater). The system may comprise an electric heater comprising at least one heating element for heating an aerosol-forming substrate, a power supply, and electric circuitry connected to the electric heater and to the power supply and comprising a memory. The electric circuitry may be configured to measure an initial electrical resistance (R1) of the electric heater; measure a subsequent electrical resistance of the electric heater after the measurement of the initial electrical resistance; determine the difference (?R) between the initial electrical resistance and the subsequent electrical resistance; determine that an adverse condition is present if the difference is greater than a maximum threshold value (?Rmax) or less than a minimum threshold value (?Rmin) stored in the memory; and control a power to the electric heater and/or provide an indication if the adverse condition is present.Type: ApplicationFiled: January 2, 2020Publication date: May 7, 2020Applicant: Altria Client Services LLCInventors: Stephane BILAT, Guillaume COLOTTE
