Abstract: Methods, systems, and devices for analyzing communication messages (e.g., emails) and selecting corresponding actions are described. In some database systems, a user may receive multiple messages at a user device. To efficiently determine responses to these messages, the user device may send the messages to a backend server for analysis. The server may perform natural language processing (NLP) to classify the message with one or more binary classifications and may extract metadata from each message. Based on the classifications and the metadata, the server may determine one or more actions the user device may perform to respond to each message. The server may send instructions to the user device indicating the suggested actions, and the user device may display these actions as options to a user. Additionally, the user device may use the classifications and metadata to automatically generate one or more communication templates in response to the message.

Abstract: The present invention discloses a current phase locking and driver pulse generation method for wireless charging for electric vehicles. By monitoring the resonant current iL2 of the receiving coil, the proposed method generates the synchronization signal accurately based on the phase of the current iL2. Moreover, it controls the phases of driver pulses of switching transistors according to the synchronization signal so as to control the turn-on moment and turn-off moment of the switching transistors in the secondary rectifier. As a result, by using the proposed method, the pulse losing of the switching transistors in the secondary active rectifier can be avoided; the stable and reliable phase locking of the high-frequency resonant current and generation of driver pulses can be achieved; the anti-interference capability can be greatly enhanced, and the stability and reliability of the wireless charging system for electric vehicles can also be improved.

Abstract: Described herein is a system and method for overlapping migration to another host node with a customer request to stop or reboot a virtual machine. A customer request is intercepted. Determination whether or not migration of the virtual machine on the source host node is capable of being performed. When the migration of the virtual machine on the source host node is capable of being performed, the virtual machine is stopped on the source host node, and, the virtual machine is migrated to an updated host node. When the customer request is a stop of the virtual machine, the virtual machine is stopped on the updated host node. When the customer request is a reboot of the virtual machine, the virtual machine is rebooted on the updated host node.

Abstract: A method and a system for reducing current noise of a touch terminal are provided. The method includes: determining that a user receives a voice call via an earpiece of the touch terminal, and controlling the touch terminal to switch from a first touch scan frequency to a second touch scan frequency, where the second touch scan frequency is less than the first touch scan frequency. As can be seen, if the user receives the voice call via the earpiece of the touch terminal, the touch terminal is controlled to switch from the first touch scan frequency to the second touch scan frequency, to effectively reduce the current noise heard by the user by decreasing the touch scan frequency of the touch terminal, so that the periodic current noise is outside a frequency band perceptible to a human ear, thereby improving user experience when receiving the voice call.

Abstract: There is provided an association analysis method and apparatus. An original database is divided into projection databases, each not contributing to a support count of a frequent item set of another. The projection databases are used for sequential-pattern association analysis performed respectively by nodes corresponding to the projection databases. Local frequent item sets and corresponding support counts obtained by the nodes are combined. Since an established projection database does not contribute a support count of a frequent item set of another projection database, different nodes can perform association mining, including pruning, on different projection databases respectively.

Abstract: Disclosed are a pH-responsive amphoteric surfactant N-lauryl-(?-alkyl)-?-aminopropionic acid and a preparation method and uses thereof. An alkylamine and a solvent are added to a three-necked flask, stirred for complete dissolution, slowly dropwise added with methyl ?-alkyl-acrylate and reacted at room temperature after the ice-water bath is removed. The reaction mixture is refluxed in water bath and evaporated under rotation to remove the solvent and the residual methyl ?-alkyl-acrylate to give N-lauryl-(?-alkyl)-?-aminopropionic acid. Then N-lauryl-(?-alkyl)-?-aminopropionic acid and water are added to a three-necked flask, slowly dropwise added with a sodium hydroxide solution and reacted in water bath to give a crude product, which is filtered and dried to give a purified surfactant sodium N-lauryl-(?-alkyl)-?-aminopropionate. This surfactant is suitable for the foamed acid system and its performance can be switched by adjusting pH due to pH sensitivity.
