Abstract: This application discloses an image coding method comprising: obtaining a plurality of groups of human skeleton data associated with performing an action by a human body, wherein each group of the human skeleton data comprises joint data associated with a joint for performing the action; extracting, based on joint data in the plurality of groups of human skeleton data, a motion feature matrix corresponding to the plurality of groups of human skeleton data; and encoding the motion feature matrix to obtain a motion feature image.

Abstract: Provided is an automatic compensation, balancing and tensioning conveying chain wherein the conveying chain can automatically adjust the guide rails to extend and retract and be automatically tensioned and balanced to avoid the influence on the conveying efficiency of the conveying chain due to the slack of the conveying chain. In addition, the guide rail position maintaining components provide a reverse compensation force to the telescopic guide rail when the guide rail pre-warning limiting switches are triggered, so as to reduce the imbalance of movements of the sliding trolleys and avoid a situation that the sliding trolley may trigger an extreme position signal in advance to cause a false alarm and stop the entire conveying chain, thereby guaranteeing a dynamic balance of two tensioning stations and completely eliminating an elasticity change of the chain.

Abstract: A method for fabricating a wire strand from parallel steel wires for a main cable of a suspension bridge, the method including: 1) selecting and coloring a steel wire as a marking steel wire which is to be positioned at a vertex of a wire strand including a plurality of parallel steel wires and having an equilateral polygon section; 2) drawing position markers at positions of the standard steel wire corresponding to control points of splay cable saddles, center points of main cable saddles, middle points of side spans, a middle point of a middle span, and starting points of anchor heads of anchor spans of a suspension bridge; 3) relaxing and shaping coils of the steel wires to yield a prefabricated wire strand; 4) preforming the positions of the cable saddles; 5) coiling the wire strand including; and 6) casting anchor of the wire strand.

Abstract: A damping control method for a lower-limb prosthesis, comprising the following steps: isolate the driving motor of the lower-limb prosthesis from the driving voltage; the driving motor is driven to rotate by the force that results from locomotion of a human's CoM (Center of Mass), and generates an alternating induced voltage, when the driving motor behaves as a generator; connect output terminals of the driving motor with a full-bridge rectification circuit that is made of Schottky diodes to transform the alternating induced voltage to a direct-current voltage; connect the output terminals of the full-bridge rectification circuit with a controlled switch to form a closed circuit, which will generate induced current from the induced voltage; control the on-off ratio of the controlled switch with a Pulse-Width-Modulation signal to generate a controllable motor current, which will result in controllable braking torque under the magnet field of the driving motor.
