Abstract: Provided is a two-stage reverse-torque bent screw orientation tool. An existing bent screw orientation technology has the technical problems of large friction resistance, difficult control of a borehole track, a low drilling speed and the like, and restricts economic, safe and long-acting development of oil and gas. In order to solve the above problems, the two-stage reverse-torque bent screw orientation tool is invented and composed of a first-stage clutch mechanism and a second-stage clutch mechanism, and the first-stage clutch mechanism and the second-stage clutch mechanism are both composed of a battery, a battery compartment, a pressure sensor, an electromagnetic valve, a body, a plug, a piston, an outer tooth cylinder, an inner tooth cylinder, a transmission cylinder, a connecting cylinder, a bearing, a limiting cylinder, a lower joint, a thrust bearing, a battery compartment, a circuit board, a cover plate and the like.

Abstract: Disclosed are a wireless remote control method and system for controllable rotary sliding guiding drilling. An upper end of a controllable rotary sliding guiding drilling mechanism is provided with a drill rod; and the wireless remote control system for controllable rotary sliding guiding drilling further comprises: an MWD arranged at a lower end of the controllable rotary sliding guiding drilling mechanism; a bent screw drill tool mounted at a lower end of the MWD; a drill bit mounted at a lower end of the bent screw drill tool, the drill bit being connected with the bent screw drill tool through a connector; and a clutch module mounted on the controllable rotary sliding guiding drilling mechanism, the clutch module comprising an electromagnetic valve, a processor, an internal pipe pressure sensor, an external pipe pressure sensor and a wireless data transmission module.

Abstract: A method, apparatus and system for acquiring an input event in a computer system comprising different priorities for processes are provided, the method comprising: executing a servant process and a master process, wherein the servant process comprises a higher priority than the master process and an input event list; and upon the servant process acquiring an input event and determining that the input event is in the input event list, the servant process transmitting the input event to the master process. A servant process with a high priority is used to acquire input events, which facilitates the operation of other processes and enhances process execution efficiency.

Abstract: A method is disclosed for folder transfer based on instant messaging (IM). The method includes receiving from an IM sender a transfer request for transferring a folder-to-be-transferred. The folder-to-be-transferred may contain a plurality of files. The method also includes receiving from the IM sender folder information of the folder-to-be-transferred, determining a receiving folder corresponding to the folder-to-be-transferred on a predetermined storage location, and determining files-to-be-transferred from the plurality of files corresponding to the folder-to-be-transferred based on the folder information. Further, the method includes sequentially sending one transfer request for each of the files-to-be-transferred to the IM sender through a same network connection, receiving the files-to-be-transferred sent sequentially by the IM sender through the same network connection, and storing the received files-to-be-transferred in the receiving folder.

Abstract: A method for switching video resolution includes: confirming that a video sender and a video receiver have established a video communication connection, and obtaining an initial resolution of the video sender; confirming that bandwidth of the video communication connection and hardware of the video sender meet preset conditions, and switching the initial resolution of the video sender to a target resolution, in which the target resolution is higher than the initial resolution. After establishing video communication connections between terminals, when there are available bandwidth and hardware of the terminal using video communication, the resolution of terminal may be switched to provide a more clear video communication for terminal user, and guarantee smooth switching of resolution.
