Abstract: An aerosol-generating device. The cavity defined together by the storage portion and the mouthpiece for accommodating the aerosol-generating substrate can effectively fix the aerosol-generating substrate, hereby preventing the aerosol-generating substrate or a tobacco residue from falling during a smoking process. In addition, when a user directly pulls an extractor out of a main body, that is, the storage portion and the mouthpiece are subjected to an axially force, the mouthpiece can radially expand outward such that the mouthpiece is separated from the storage portion. Before the extractor is detached from the main body, the main body would restrict the end of the mouthpiece adjacent to the main body from radially expanding outward.

Abstract: The present invention relates to a releasing mechanism, an aerosol generating device, a releasing method, and a smoking producing article. The releasing mechanism comprises: a rotary portion connected to the aerosol generating device rotatably between a first position and a second position, an aerosol-forming substrate and a heating body are relatively movable in a circumferential direction during switching from the first position to the second position; both in the first position and in the second position, the aerosol-forming substrate is in contact with the heating body. By using the releasing mechanism of the present invention, a user is allowed to easily pull out the aerosol-forming substrate from the heating body, and it is convenient to use and also facilitates cleaning of the aerosol generating device by a user.

Abstract: A method detects anomalies in a system having sensors for collecting multivariate sensor data including discrete event sequences. The method determines, using a NMT model, pairwise relationships among the sensors based on the data. The method forms sequences of characters into sentences on a per sensor basis, by treating each discrete variable in the sequences as a character in natural language. The method translates, using the NMT, the sentences of source sensors to sentences of target sensors to obtain a translation score that quantifies a pairwise relationship strength therebetween. The method aggregates the pairwise relationships into a multivariate relationship graph having nodes representing sensors and edges denoted by the translation score for a sensor pair connected thereto to represent the pairwise relationship strength therebetween. The method performs a corrective action to correct an anomaly responsive to a detection of the anomaly relating to the sensor pair.

Abstract: The present invention provides a temperature control method, applied to an aerosol generation apparatus. The aerosol generation apparatus comprises a detection element and a heating element for heating an aerosol generation base material. The specific temperature control method comprises: in a first stage, controlling the heating element to increase the temperature from an initial temperature to a first temperature; in a second stage, controlling the heating element to decrease the temperature from the first temperature to a second temperature; and in a third stage, controlling the heating element to perform constant temperature operation at the second temperature, and if the detection element detects suction, controlling the heating element to increase the temperature to a third temperature. The present invention also provides an aerosol generation apparatus and an aerosol generation system. Temperature change of the heating element is controlled according to a suction action of a consumer.

The method includes generating sentences of discrete event sequences for multiple sensors. The method also includes building a sensor relationship network in response to generating the sentences of discrete event sequences. The sensor relationship network is analyzed to determine relationships between the multiple sensors. The method further includes performing fault diagnosis based on the sensor relationship network and the relationships between the multiple sensors.

Abstract: Methods and systems for system maintenance include identifying patterns in heterogeneous logs. Predictive features are extracted from a set of input logs based on the identified patterns. It is determined that the predictive features indicate a future system failure using a first model. A second model is trained, based on a target sample from the predictive features and based on weights associated with a distance between the target sample and a set of samples from the predictive features, to identify one or more parameters of the second model associated with the future system failure. A system maintenance action is performed in accordance with the identified one or more parameters.
