Abstract: This application discloses a heat dissipation structure for an optoelectronic module and an electronic device. The heat dissipation structure includes: an electronic chip; a plurality of optical engines, the plurality of optical engines being distributed along a periphery of the electronic chip; and a cold plate. The cold plate includes: a main cold plate for dissipating heat for the electronic chip; a secondary cold plate for dissipating heat for at least one of the plurality of optical engines; and a heat pipe assembly corresponding to the secondary cold plate. The heat pipe assembly includes at least one heat pipe, which has an evaporating end connected to the secondary cold plate and a condensing end connected to the main cold plate. The main cold plate is equipped with a flow channel for dissipating heat for the heat pipe assembly, and the secondary cold plate has a maintenance operation position.

Abstract: Embodiments of this application provide a packet sending method and an intelligent terminal, and a storage medium. The method is applied to an intelligent terminal provided with a plurality of wireless antennas comprising at least one directional antenna, and the method includes: obtaining a destination MAC address of a to-be-sent packet; determining, based on a mapping relationship between a MAC address and a wireless antenna, a target wireless antenna corresponding to the destination MAC address, where the mapping relationship is configured based on an orientation relationship between the intelligent terminal and different neighboring devices, the different neighboring devices include other intelligent terminals and/or a management device, the management device is configured to store data collected by each intelligent terminal, and the target wireless antenna is one of the at least one directional antenna; and sending the to-be-sent packet by using the target wireless antenna.

Abstract: This application discloses a watermark processing method, an electronic device, and a storage medium. The watermark processing method includes: obtaining to-be-inserted watermark information; setting a transparent image layer on a display screen of a terminal based on a size of an image layer window, where the size of the image layer window is determined based on a size of the display screen of the terminal; and drawing the watermark information on the transparent image layer at specified transparency.

Abstract: Embodiments of the present application disclose a roaming method for a wireless terminal. The method includes: detecting that first comprehensive signal quality of a first wireless terminal is lower than a first specified threshold, reducing a transmit power by a first specified value, wherein the specified packets are null packets, and sending specified packets to the first wireless terminal, so that the first wireless terminal broadcasts a probe request; sending, to neighboring APs, a scan request carrying a first identifier and a first channel accessed by the first wireless terminal, so that the neighboring APs return a scan response carrying the first identifier and third comprehensive signal quality; selecting a switch-to AP from the neighboring APs based on the first comprehensive signal quality and third comprehensive signal quality; and sending a transmit-power increasing notification carrying the first identifier and a second specified value to the switch-to AP.

Abstract: This application relates to a chip-to-module cable assembly, includes a first joint, a second joint and a first flexible PCB cable, the flexible PCB cable, including flexible material parts located on upper and lower layers and a connection portion located on a middle layer, wherein the connection portion comprises two rigid material portions respectively located at end portions of the flexible material parts on the upper and lower layers and a hollow portion between the two rigid material portions, the flexible material parts each comprises at least one conducting wire, one end of each of the at least one conducting wire is connected to a first interface terminal of the first joint, and another end of the conducting wire is connected to a second interface terminal of a second joint.

Abstract: A method and an apparatus for updating table entries of a TCAM are disclosed. The method comprises: creating a virtual TCAM list, of which respective first TCAM table entries are one-to-one corresponding to respective second TCAM table entries stored in a hardware TCAM; determining, in idle resources of the hardware TCAM, a storage position of a second TCAM table entry to be updated corresponding to a first TCAM table entry to be updated, according to a pre-specified precedence relationship between the storage positions of the first TCAM table entry to be updated and other first TCAM table entry in the virtual TCAM list; and performing an updating operation on the second TCAM table entry to be updated based on the determined storage position.
