摘要： A spontaneous-extending and anti-rotation scoliosis correcting system comprises pedicle screws and a plurality of correcting rods locked with the pedicle screws. Each correcting rod includes at least one sleeve and at least one inserting rod which can be inserted into the sleeve. The inner wall of the sleeve and the inserting rod are the same in shape and are in clearance fit. A positioning mechanism for restricting the relative rotation of the inserting rod with respect to the sleeve is arranged on a matching surface between the inserting rod and the sleeve. The scoliosis correcting system has the benefits of ensuring the lateral stability and the anti-rotation function for scoliosis correction; having the performance of spontaneous extending along the growth direction of the spine; and ensuring both the short-term operating effect and the long-term curative effect.

摘要： A depth limiting device includes an axial braking structure; a limited shrinking structure, the limited shrinking structure surrounding a moving object, and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.

摘要： A computer-implemented method and system for deduplicating sub-chunks in a data storage system selects a data chunk to deduplicate and generates a sketch for the selected data chunk. A similar data chunk is searched for using the sketch. A set of fingerprints corresponding to sub-chunks of the similar data chunk is loaded. The set of fingerprints for the similar data chunk is compared to a set of fingerprints of the selected data chunk and the selected chunk is encoded as a set of references to identical sub-chunks of the similar data chunk and at least one unmatched sub-chunk.

摘要： A signal processing apparatus includes a first baseline wander correcting unit, provided in a processing path in which a predetermined processing is performed on an input signal, which corrects baseline wander by a feedforward and a second baseline wander correcting unit, provided anterior to the first baseline wander unit, which corrects the baseline wander by a feedback control. The first baseline wander correcting unit derives an amount of baseline wander. Further, it calculates a value corresponding to an average value of the amount of derived baseline wander and fine-adjusts a correction amount of baseline. Then it corrects the baseline wander by using the fine-adjusted baseline amount. The second baseline wander correcting unit calculates a value corresponding to an average value of the amount of baseline wander derived by the baseline wander derivation unit and coarse-adjusts a correction amount of baseline, and corrects the baseline wander by using the coarse-adjusted baseline amount. The fine correcting by the first baseline wander correcting unit and the coarse correcting by the second baseline correcting unit ensure efficient correction of baseline wander.

摘要： A system and method are disclosed for providing efficient data storage. A plurality of data segments is received in a data stream. The system preliminarily checks in a memory having a relatively low latency whether one of the plurality of data segments may have been stored previously in a data segment repository. The memory having the relatively low latency stores data segment information. In the event that the preliminary check determines that one of the plurality of data segments may have been stored in the data segment repository, a memory having a relatively higher latency is checked to determine whether the data segment has been stored previously in the data segment repository.
