摘要： A toy water gun for water streaming and spraying comprising a piston type water gun, a nozzle, an adjustment sleeve and a position adjustment mechanism. The water gun comprises a cylinder, a piston fitted in a cavity of the cylinder, a pump rod connected to the piston, a handle disposed on the pump rod, and a water duct mounted on and communicating with the cylinder. The nozzle is mounted on the water duct, rear and front ends of the nozzle are disposed with a water inlet and a water outlet respectively, and the water inlet communicates with the water duct. The adjustment sleeve is sleeved on the nozzle, an inner side wall of the adjustment sleeve makes sealing contact with an outer side wall of the nozzle, the adjustment sleeve is disposed with a sealing plate having a water jet hole located right in front of the water outlet.

摘要： A hybrid class B channel state information (CSI) reference signal (CSI-RS) scheme is discussed which configures one cell-common beamformed CSI-RS resource for beam tracking and another UE-specific beamformed CSI-RS resource for CSI feedback. The cell-common beamformed CSI-RS resource may be transmitted at a longer periodicity and shared by user equipments (UEs) in the cell. The beamforming may be cycled over a set of predefined weights transparent to UE. The UE-specific beamformed CSI-RS may be transmitted at a shorter periodicity and can be activated dynamically to allow resource sharing among multiple UEs. The UEs will report a CSI for the cell-common beamformed CSI-RS resource which provides a quality indicator for the associated cell-common beam and is utilized by the base station to determine the precoding weight for the UE-specific beamformed CSI-RS resource. Both resources can be configured with different parameter sets, such as number of ports, codebook type, and CSI reporting parameters.

摘要： The present disclosure provides a method for transmitting a large object, after a server establishes a session with a client, the method includes: the server divides a pre-transmitted large object into data blocks, and transmits one by one in sequence acquired data blocks and their sizes to the client; the client determines whether a received data block is transmitted successfully, if the received data block is transmitted successfully, the data block is saved, and a current data block transmission success message is returned to the server; if the received data block is not transmitted successfully, an end session request message or a re-transmitting current data block request message is returned to the server; and the server transmits the corresponding data block and its size or ends the session according to the received messages. The present disclosure further provides a system for transmitting a large object. When there is an error in transmitting a data block of a large object, the method and the system in the present disclosure process it in advance, thus saving bandwidth resources.
摘要翻译： 本公开提供了一种用于在服务器与客户端建立会话之后发送大对象的方法，所述方法包括：所述服务器将预发送的大对象划分为数据块，并且逐个地依次获取数据块和 他们的大小给客户; 如果所接收的数据块被成功发送，则客户端确定接收到的数据块是否被成功发送，数据块被保存，并且当前数据块传输成功消息被返回给服务器; 如果接收到的数据块没有被成功发送，则结束会话请求消息或重传当前数据块请求消息被返回给服务器; 并且服务器根据接收到的消息发送对应的数据块及其大小或结束会话。 本公开还提供了一种用于发送大对象的系统。 当发送大对象的数据块存在错误时，本公开的方法和系统预先处理它，从而节省带宽资源。
