Abstract: A battery charger compatible with AC/DC power sources is provided. The battery charger comprises a power output port connected to a battery, a rectifier electrically connected between an AC connecting port and the power output port, and a power conversion unit electrically connected between a DC connecting port and the power output port. When the AC connecting port receives an AC power, the rectifier rectifies the AC power into a DC power and outputs the DC power to the power output port. When the DC connecting port receives an DC input power and the AC power is not received by the AC connecting port, the power conversion unit transforms the DC input power into the DC power and outputs the DC power to the power output port. The battery charger is a 2-in-1 charger that can charge the battery using either the DC power or the AC power.

Abstract: A user equipment (UE) in a wireless communication network determines that a radio link failure (RLF) has previously occurred within a threshold distance from a current location of the UE. Responsive to determining that the RLF has previously occurred, the UE determines an expected beam to be encountered and that is associated with the RLF. The UE generates a first beam measurement report for the expected beam. The beam measurement report includes an adjusted power measurement for the expected beam indicating that the expected beam is an optimal beam compared to at least one neighboring beam. The UE transmits the first beam measurement report to the cellular network.

Abstract: The disclosed techniques reduce a responsiveness time for a secondary node state of a database in switching from a second computing node to replace a first computing node acting in a primary node state, with both computing nodes performing the same database queries. The second node receives information regarding queries performed by the first node while in the primary state. In some embodiments, the second node retrieves, from a transaction log, log records detailing operations performed for database transactions. In some embodiments, the second node inserts, based on the log records, data records of the transactions into an in-memory cache of the second node that stores chains of database records from different transactions. Upon receiving sufficient information to switch to the primary state, the second node changes a mode of operation during failover making a committed transaction available for reads by subsequent database queries prior to record reordering.

Abstract: Techniques are disclosed that pertain to tracing performance information. A computer system receives a request from a second computer system to perform operations pertaining to a database statement of a database transaction that is being executed by the second computer system. The computer system determines that the request is an initial request received by the computer system to perform work of that database statement. Based on the determining, the computer system stores, in association with the database statement, baseline information that is indicative of a baseline state of one or more performance metrics. Subsequent to performing the operations, the computer system receives a request from the second computer system for performance information. The computer system derives the performance information from a difference between the current state of the one or more performance metrics and the baseline state. The computer system sends the performance information to the second computer system.

Abstract: The present invention provides a method for the preparation of an insensitive high enthalpy explosive Dihydroxylammonium 5,5?-bistetrazole-1,1?-diolate (TKX-50) in the presence of N,N-dimethylformamide, N,N-dimethylacetamide, or N-Methyl-2-pyrrolidone as a solvent via a four-step, one-pot reaction route to obtain a final product after four reaction steps. The more dangerous intermediate diazidoglyoxime may be solved by the one-pot method without the need of isolation. Further, the cyclization reaction is carried out in the presence of dropwisely added concentrated sulfuric acid to replace hydrochloric gas so no hydrochloric gas generator is needed to greatly reduce the amount of waste acid so as to effectively reduce the cost by avoiding using hydrochloric gas steel cylinders which require much safety equipment.
