Compound spinal rods function as part of the dynamic stabilization prosthesis to provide load sharing with motion preservation as part of a dynamic stabilization prosthesis. Compound spinal rods are used to span from one vertebra to an adjacent vertebra. Compound spinal rods include a first rod connected by a linkage to a second rod. The linkage allows for movement of the first rod relative to the second rod. The movement permitted by the compound spinal rod is designed to enhance the ability of a dynamic stabilization prosthesis to more closely approximate the natural kinematics of the spine without impairing stabilization of the spine.

A resource load balancing method concretely relates to content copy based resource load balancing method and an automatic distribution type resource monitoring structure. The method comprises: dynamically copying content of resource starting from every independent resource storage center node according to resource access condition of local node and information of resource storage center, selects a proper resource storage node for copied resource, at last accomplishes load balancing for resource. The resource storage center information such as bandwidth, magnetic disc space and credit needed by load balancing are collected and stored in monitoring information database of global hot spare management center by distribution type resource monitoring script program.

Methods and instruments for preparing a disc space and for forming interbody devices therein are provided. The instruments include distractors having enlargeable portions positionable in the disc space for distracting the disc space. The enlargeable portions can also provide form about or against which an interbody device of a first material is placed. A second material may be placed in the disc space in the space previously occupied by the distractors.

Methods and devices for static or dynamic spine stabilization include an anterior plating system that allows longitudinal and pivoting motion of the plates and of the stabilized vertebras. In one embodiment a spine fixation assembly for connecting a first vertebra to a second vertebra includes a first plate configured to be attached to one or more locations of the first vertebra and a second plate configured to be attached to one or more locations of the second vertebra. The first plate is pivotally connected to the second plate and may also allow longitudinal and / or horizontal motion of the plates relative to each other.

Methods and systems for stabilizing an on-screen code on a display of a mobile device are described. A code is displayed on a mobile device as an on-screen code. The user holds the mobile device in front of a code scanner so that the on-screen code can be scanned. A code stabilization application on the mobile device assists in stabilizing and / or centering the on-screen code through changing its position, shape, and / or size based on data and / or measurements from sensors. The code stabilization application stabilizes the on-screen code for easy scan-ability to speed up the scanning process.

The invention discloses a real-time video stabilization method based on a homography matrix and is used for stabilizing video sequences obtained by devices such as a handheld DV and an unmanned aerial vehicle. The method comprises the steps of A, extracting angular points uniformly distributed in images; B, calculating an interframe optical flow vector and tracking an interframe motion angular point through utilization of the interframe optical flow vector; C, calibrating the tracked angular point through utilization of a layered affine calibration algorithm; D, solving an interframe homography matrix through utilization of a random sampling unification algorithm; E, separating interframe active motion compensation quantity and distortion calibration quantity by employing a kalman filter; and F, carrying out stabilization conversion on one video image by employing the homography matrix, the motion compensation quantity and the distortion calibration quantity to obtain stabilized current frame output. According to the method, shake existing in the video sequences can be effectively removed, the algorithm complexity is relatively low, the operation speed is fast, and the high application value is provided for the real-time video processing system.

The invention discloses a chromium-contaminated soil remediation method, belonging to the technical field of environment engineering. The method comprises the following steps of: dissolving out hexavalent chromium in the chromium-contaminated soil, separating the soil from water, treating trivalent chromium-contaminated soil, treating hexavalent chromium sewage and treating filter residue; the dissolution efficiency of the hexavalent chromium in the chromium-contaminated soil can be improved by the KH2PO4 solution; the trivalent chromium-contaminated soil is treated by biochar made of municipal sludge, so that waste reclamation and secondary utilization of the contaminated soil can be realized; Na2S2O5 can be added into the hexavalent chromium sewage and is used for adjusting the reaction environment, so that the efficiency of converting hexavalent chromium into trivalent chromium can be improved; a flocculating agent is used for accelerating the precipitation and concentration of the trivalent chromium; the filtered water can be used as flushing water for recycling, so that the method is economical and environment-friendly; and a curing stabilization method is used for treating the filter residue, so that the chromium in the filter residue is passivated, and the national environmental standard requirements can be reached. According to the method, the hexavalent chromium and the trivalent chromium are respectively treated, and the solid and the solution are respectively treated, so that the treatment efficiency is improved, the treatment effect is guaranteed, and the method has the characteristics of being free from secondary pollution, low in cost, high in resource utilization rate, etc.
