Abstract: A method for charging a rechargeable lithium-ion battery in an aerosol-generating system is provided, the method including: initiating charging of the rechargeable lithium-ion battery; monitoring an electrical parameter indicative of a charging rate of the rechargeable lithium-ion battery; determining the charging rate of the rechargeable lithium-ion battery by monitoring a change of the electrical parameter over a given time period; and comparing the determined charging rate to a reference charging rate, the reference charging rate being defined by an expected change in the monitored electrical parameter; and if the charging rate deviates from the reference charging rate, inhibiting the rechargeable lithium-ion battery from being charged. A charge controller for an aerosol generating system is also provided. An aerosol-generating device is also provided. A charging case for an aerosol generating device is also provided.

Abstract: A method comprising: receiving data from a first equipment health monitoring system, the data being for a plurality of parameters of a propulsion system; determining whether the data received from the first equipment health monitoring system includes data for a first parameter of the propulsion system; and instructing deployment of a second equipment health monitoring system to monitor the first parameter where it is determined that the data received from the first equipment health monitoring system does not include data for the first parameter.

Abstract: Apparatus comprising: a propulsion system; a first equipment health monitoring system configured to generate data for a plurality of parameters of the propulsion system; a second equipment health monitoring system configured to generate data for one or more parameters of the propulsion system, at least one of the one or more parameters to be monitored by the second equipment health monitoring system being different to the plurality of parameters to be monitored by the first equipment health monitoring system.

Abstract: An aerosol-generating device is provided, including: a first housing portion defining a chamber configured to receive an aerosol-forming substrate; a second housing portion; a heater positioned within the first housing portion; a power supply positioned within the second housing portion; control circuitry configured to control a supply of power from the power supply to the heater; and a first button and a second button each positioned on the first housing portion or the second housing portion, the first button having at least one of a different size and a different shape from the second button, the first button being configured to activate a first function of the aerosol-generating device, the second button being configured to activate a second function of the aerosol-generating device, and the first function being different from the second function. An aerosol-generating system including the aerosol-generating device and an aerosol-generating article is also provided.

Abstract: A system is provided, including: an aerosol-generating device arranged to interact with a tobacco stick and/or comprising a charging device associated with an aerosol-generating device, in which the aerosol-generating device and/or the charging device include at least one light emitter, a controller to adjust at least one visual characteristic of light emitted by the at least one light emitter based on a local time retrieved from a timer, and a communication interface to exchange data with a mobile terminal, the data including instructions for adjusting the at least one visual characteristic; and the mobile terminal to display a user interface for inputting the instructions, in which the instructions include a time setting, and in which the user interface includes a first user interface element for inputting the time setting.

Abstract: A rotor assembly for a gas turbine engine. The rotor assembly comprising: a rotor comprising a plurality of rotor blades, wherein the rotor is arranged to rotate about an axis of rotation; a sensor arranged to measure a rotational signal indicative of the rotational speed of the rotor at a measurement point on the rotor; and a processor in communication with the sensor. The processor is arranged to receive the rotational signal and derive a rotor impact signal based on an offset in the measured rotational speed of the rotor at the measurement point. The rotor has an axial length (L) parallel to the axis of rotation, and the sensing apparatus is arranged to measure the rotational speed of the rotor at a measurement point along the axial length of the rotor, the measurement point corresponding to a position at or near an antinode of a torsional oscillation of the rotor resulting from an impact event.
