A laser assembly and a translation prism assembly of the light emission component are located on the mounting shell and are exposed to the front surface of the circuit board through the mounting hole, and a light exiting direction of a light processing assembly of the light emission component forms a first preset angle with a light entering direction thereof in a plane parallel to the circuit board.

Abstract: This application discloses data transmission that includes: dividing to-be-transmitted content into a plurality of data units at a session layer; transmitting the data units to the target terminal device by using a first transmission channel as a responsible channel of the to-be-transmitted content; distributing, by the session layer in a case that the session layer switches the responsible channel of the to-be-transmitted content from the first transmission channel to a second transmission channel with a different transmission protocol, the data units to the second transmission channel; and transmitting the data units distributed by the session layer to the target terminal device through the second transmission channel. In data transmission in this application, the session layer controls switching of the channels and distribution of the data units, so that the transmission sequence is free from constraints of protocols and the degree of freedom in data transmission is increased.

Abstract: This application provides a method for accessing a wireless network performed by an electronic device acting as a station (STA). The method includes: determining interference information of a target channel, the target channel being a channel currently connected between the STA and an access point (AP); determining a target network access parameter group corresponding to the interference information; disconnecting the target channel between the STA and the AP; and accessing the AP via a new channel established between the STA and the AP according to the target network access parameter group.

Abstract: A data processing method is performed by a receiving device. The method includes: receiving, through at least two network channels, data elements transmitted by a transmitting device, the data elements comprising delivery serial numbers; obtaining subsequent data elements of the received nth data element on the basis of the delivery serial numbers; and determining, when the subsequent data elements comprise a target data element, that a delivery result of the nth data element is discarded, a state of the target data element being a complete state, the target data element having a same data type as the data type of the nth data element, the target data element being an independent data element, the data type being determined on the basis of an effect of the data element, and a dependence degree of the independent data element on other data elements during post-processing being less than a specified degree.

Abstract: A method for live migration of a virtual machine includes receiving a data packet that is sent to a migrated virtual machine on the source physical machine in a stage when the migrated virtual machine is suspended, and caching the received data packet; and sending the cached data packet to the migrated virtual machine on the destination physical machine after it is sensed that the migrated virtual machine is restored at the destination, to speed up restoration of a TCP connection inside the virtual machine. The apparatus of the present disclosure includes a caching unit and a data restoration unit. The method and apparatus of the present disclosure improve a restoration speed of the TCP connection, make live migration of a virtual machine more imperceptible for users, and improve user experience.

Abstract: Certain aspects of the present disclosure relate to techniques for processing (e.g., such as tasks for wireless communications and/or multimedia). According to certain aspects, a method for low power low latency data exchange generally includes providing timing information from a first processing entity to a second processing entity indicating when the second processing entity is to next process a message exchange between the first and second entities using a shared memory space, taking action to exit a low power state, based on the timing information, to access the shared memory space to process the message exchange, and entering the low power state after processing the message exchange.
