Abstract: A cigarette device management system includes an information management module, and a maintenance prediction module, a device state acquisition module and a purchase statistics module which are in communication connection with it. The maintenance prediction module is built by an artificial neural network model and is configured to predict a failure interval. The device state acquisition module acquires a device operating parameter and an operating duration of the device in real time, and compares the device operating parameter with a safety parameter range. In accordance with the system, the maintenance timing of the device can be predicted, the purchase quantity of the spare part and the purchase timing of the spare part also can be predicted.

Abstract: The present disclosure relates to systems and methods for determining a potential malicious event. The systems and methods may obtain real-time information related to a vehicle. The systems and methods may determine a probability of arising malicious event based on the real-time information of the vehicle. The systems and methods may determine whether the probability of arising malicious event exceeds a probability threshold. The systems and methods may in response to a determination that the probability of arising malicious event exceeds the probability threshold, determine that a potential malicious event exists.

Abstract: A terminal and electrical water-resistance method, the terminal includes: a circuit board, a battery providing a power source for the circuit board, a housing provided with a transparent medium used for reflecting light; the circuit board includes: a detection module, configured to: emit light towards the transparent medium, receive the light reflected by the transparent medium to convert into electric signal data to send to a control module; the control module, configured to: receive the electric signal data to compare with preset data, trigger the power-off switch when a difference value between the electric signal data and the preset data reaches a preset threshold which is preset according to the light and the transparent medium, wherein, the preset data are electric signal data when the light is totally reflected by the transparent medium; a power-off switch configured to: disconnect a connection between the circuit board and the battery after triggering.
