Abstract: The present disclosure provides a multi-path universal asynchronous transceiver (UART) and transmission method thereof. The multi-path UART comprises a first buffer, a second buffer, and a tx aggregation and arbitration circuit respectively coupled to the first buffer and the second buffer and presets a predetermined threshold. The tx aggregation and arbitration circuit polls the first buffer and the second buffer according to the predetermined threshold, and executes an arbitration procedure on the first buffer and the second buffer to obtain at least one of first log information packet and at least one of second log information packet correspondingly. Thus, when inputting a plurality of log sources, it is not necessary to have a plurality of output pins and to avoid disorder caused by the cross-influence of multiple log information for resource conservation and providing log information correctness.

Abstract: The present disclosure discloses an amine derivative and an organic electroluminescent device thereof, and relates to a technical field of organic photoelectric materials. The technical problem to be solved by the present disclosure is that the current light extraction material has poor thermal stability and the organic electroluminescent device has short service life. The amine derivative of the present disclosure is a diamine with a bridging group containing a fluorenyl group or a spirofluorenyl group, and the substituent group on N contains at least one benzoxazolyl group, benzothiazolyl group or benzimidazolyl group. The organic electroluminescent device of the present disclosure comprises an anode, an organic layer, a cathode and a light extraction layer, the organic layer is located between the anode and the cathode, and the light extraction layer comprises the amine derivative of Formula I according to the present disclosure.

Abstract: A fluid valve includes a main valve body, a valve seat, a valve core and a valve actuator. The main valve body has a fluid inlet, and a fluid outlet. The valve core includes a core body having a main passage channel, a core inlet, and a core outlet. The core body has a curved guiding surface for forming a residual passage channel between the curved guiding surface and the valve seat. The valve core may be moved between a fully opened position, a partially opened position, and a fully closed position. In the partially opened position, the valve core is moved such that the fluid inlet is arranged to communicate with to the core inlet and the residual passage channel for allowing passage of fluid from the fluid inlet to the fluid outlet through the main passage channel and the residual passage channel.
