Abstract: Methods, devices, and media for operating a robot arm are provided. In one method, receive a language description for specifying a target implemented by the robot arm; obtain a current state of the robot arm; and determine, according to an action model, an action to be performed by the robot arm based on the language description and the current state. With the example implementation of the present disclosure, the problem of insufficient training data of the robot arm may be alleviated. Further, the pre-trained action model may obtain the basic knowledge about the association relationship between the language description and the person action, may obtain a more accurate action model, and further obtain the action of the robot arm matching the language description in a more efficient manner.

Abstract: The present application discloses an information processing method, a task execution method, an apparatus, a device and a medium. The method includes: processing, through a target visual encoding model in a target analysis model, obtained image information to be analyzed, to obtain a corresponding target sequence; fusing, through a target feature fusion model in the target analysis model, the target sequence and obtained text information to be analyzed, to obtain a target fusion result; processing the target fusion result through a target task analysis model in the target analysis model to obtain target task information; and controlling the action execution apparatus to perform an action corresponding to the target task information. The target analysis model is obtained by training an initial analysis model and the initial analysis model comprises an initial visual encoding model and an initial feature fusion model.

Abstract: An active energy-absorbing shock absorber for perforation combined well testing includes a first energy-absorbing mechanism, a second energy-absorbing mechanism and an axial-force cushioning mechanism. The first energy-absorbing mechanism includes a gun body, a gun head, a gun tail joint, a support frame, an energy-absorbing filling layer and a detonation mechanism. The second energy-absorbing mechanism includes an intermediate connecting cylinder, an outer cylinder, a limiting step, a movable impact head, a support base, a hydraulic buffer mechanism, a piston rod, an energy-absorbing spring and an inner cavity piston. The axial-force cushioning mechanism includes a housing, a guide mechanism, a buffer shaft and a multi-stage buffer spring. The absorber with a multi-layer structure is filled with a foam aluminum material.

Abstract: Aspects of the invention provide a method and system for synchronizing a transceiver and a framer in an optical transmission network. Subsequent to achieving synchronization of an inbound data stream, an internal framer may be adapted to inform a downstream device such as a full framer, that synchronization has already been attained. Accordingly, the downstream device may not need to perform resynchronization of the inbound data and can immediately start processing the inbound data. Advantageously, the internal framer may provide expedited error checking, handling and reporting prior to receipt of the data by the downstream device.
