Abstract: Embodiments of the disclosure provide devices and methods for performing a top-k function. The device can include: a memory comprising a plurality of register files for storing the data elements, the plurality of register files comprising a parent register file and a first child register file associated with the parent register file, wherein the parent register file is associated with: first interface circuitry configured for reading a first parent data element from the parent register file and receiving a first child data element and a second child data element from the first child register file; and first comparison circuitry configured for updating the parent register file and the first child register file based on the first parent data element, the first child data element, and the second child data element according to a given principle.

Abstract: Embodiments in the present disclosure provide a flexible circuit board and a display device. The flexible circuit board includes a base material, a plurality of binding pins, and a protective layer. The plurality of binding pins are located on the base material, extend in a first direction, and are arranged in a second direction; the protective layer is located on the side of the binding pins facing away from the base material, and includes a plurality of first openings and second openings for exposing the plurality of binding pins, the size of the first openings being greater than that of the second openings; and one binding pin corresponds to one first opening and at least one second opening, and the second opening is located on at least one side of the first opening in the first direction.

Abstract: A vibration isolation/damping satellite mount of a chopped carbon fiber reinforced thermoplastic composite material mainly includes two parts, and the two parts are connected through bolts. Considering the limitation of the molding process, the mount configuration is further optimized, and the mount structure is prepared by using the injection molding process. Furthermore, the vibration isolation/damping satellite mount of the chopped carbon fiber reinforced thermoplastic composite material prepared in the present invention can be used for large loads and complex working conditions, and the connectivity, overall strength stability, vibration isolation performance and service life of the mount all meet the design requirements.

Abstract: Embodiments of the present disclosure provide a communication method, a communication apparatus and an electronic device. The method includes: a first device establishes a Bluetooth connection with a second device; the first device performs an authentication processing with the second device to obtain an authentication result; and the first device performs a voice-based data interaction with the second device if the authentication result is that an authentication is successful. The method can improve the connection speed, connection success rate and communication security during the communication of the device.

Abstract: Embodiments of the present disclosure provide a method and apparatus for communication authentication processing, and an electronic device, where the method includes: transmitting, by a first device, a pairing request to a second device; receiving, by the first device, a pairing response transmitted by the second device, where the pairing response includes a first random value and first signature information, the first random value is configured to generate the first signature information; and acquiring, by the first device, a second random value and second signature information from a server according to the first random value and the first signature information, where the second random value and the second signature information are generated by the server according to the first random value and the first signature information, the second random value is configured to generate the second signature information.

Abstract: In certain embodiments, a service provided by a production server is facilitated. The production server is associated with a backup server configured to take over if the production server fails. The production server assigned a first identifier. A failover with a potential identity conflict is determined to have occurred. In the failover, the backup server has taken over for the production server and has been assigned the first identifier. A second identifier is assigned to the production server to replace the first identifier that was assigned to the production server in order to avoid the identity conflict.
