Abstract: A voice lamp includes a radiator, a voice input module, a light emitting assembly, a diffusion cover and a sound guiding tube. The voice input module is electrically connected to the light emitting assembly, and the voice input module and the light emitting assembly are both arranged in the radiator; the diffusion cover is connected to the radiator and covers the outside of the light emitting end of the light emitting assembly; the sound guiding tube is provided through the diffusion cover in the axial direction of the radiator, and the sound guiding tube is directly opposed to the voice input module. According to the application, the sound receiving effect can be improved due to the provision of the sound guiding tube.

Abstract: A battery assembly, a battery pack, and a vehicle are provided. The battery assembly includes a battery column and a voltage collection assembly disposed on one side of the battery column. The battery column includes at least one first battery, including first and second electrodes. A distance between the first electrode and the voltage collection assembly is greater than a distance between the second electrode and the voltage collection assembly. The first electrode is electrically connected to a case of the first battery, such that a potential of the first electrode is equal to a potential of the case. The voltage collection assembly includes first and second collection terminals. The first collection terminal is connected to the case and configured to collect the potential of the first electrode. The second collection terminal is connected to the second electrode and configured to collect a potential of the second electrode.

Abstract: The present application relates to the field of engineering ceramic materials, and specifically discloses a solid-phase-sintered silicon carbide article and a preparation method thereof. A method for preparing a solid-phase-sintered silicon carbide article includes the following steps: grinding of raw materials: mixing a micron-scale silicon carbide powder with a boron-containing sintering aid and wet grinding to obtain a slurry; spray granulating: adding a water-soluble carbon black and a binder to the slurry, stirring evenly, and spray granulating to obtain a granulated powder of silicon carbide; mixing; ageing: ageing the wet powder obtained by mixing to obtain a aged material; post-processing: subjecting the aged material to pugging, extruding, drying and heating.

Abstract: A method accurately evaluates a corresponding operation capacity for an operating characteristic of a to-be-evaluated object in a to-be-evaluated time period in combination with already-operated historical data of the to-be-evaluated object, which specifically includes: for a capacity influence factor in an operating process of an airspace unit, constructing a capacity similarity characteristic model to form a capacity similarity characteristic index set; acquiring historical data of an evaluation object, on the basis of the capacity similarity characteristic index set, classifying historical data samples of different time periods by a clustering algorithm, and generating a capacity similarity time period sample set to which an evaluation time period of the current evaluation object belongs; and classifying historical capacity values of the capacity similarity time period sample set by a density clustering algorithm, and calculating a capacity reference value on the basis of a maximum class cluster.

Abstract: A method and a terminal for enhancing information security, where the method includes receiving, by a terminal, an open instruction of a sensitive application, starting a security policy of the sensitive application, displaying prompt information that a notification message arrives when the notification message related to the sensitive application is received, and displaying a prompt for entering a password when an instruction for opening the notification message is received. Hence, a preset security policy is automatically started when the sensitive application is used. When the notification message related to the sensitive application is received, a corresponding password needs to be entered. This enhances information security, facilitates use by a user, and improves user experience.

Abstract: A conflict alerting method based on control voice comprises: collecting radio voice messages of a controller and a pilot and converting the radio voice messages into digital signals by an audio card of a control position; converting the digital signals into text messages by a voice recognition function and sending the text messages together to a system server; extracting, by the system server, control commands from the text messages; determining a moving track of an aircraft in a future period of time based on the control commands; identifying a possible dangerous conflict between aircrafts in combination with current location messages, motion parameter messages and future motion tracks of various aircrafts in an air traffic management system, and providing an alert prompt.

Abstract: A method for detecting an eavesdropping activity and a terminal device. The method includes determining whether a terminal device is in a conversation; when the terminal device is in a conversation, determining whether the terminal device has an application that starts a recording function; and when the terminal device has an application that starts a recording function, sending out an eavesdropping alarm prompt. By adopting the technical solutions of the present invention, an eavesdropping activity in a manner of recording may be detected.
