Individual orthopedics department positioning sheet based on medical images

InactiveCN104622572AReduce design and manufacturing timeLow selectivityDiagnosticsSurgeryInformatizationKnee Joint
The invention discloses an individual orthopedics department positioning sheet based on the medical image three-dimensional reconstruction and computerized design technology. The individual orthopedics department positioning sheet is manufactured based on 3D printing or other machining methods and is used for knee prosthesis. The positions of key positioning holes and cutting faces in knee prosthesis are particularly and accurately determined. Firstly, a skeleton model is reconstructed based on medical images; preoperative planning is carried out on the reconstructed model so as to determine important parameters of a lower extremity force line, a thighbone rotating shaft, an osteotomy reference point and the like and simulate osteotomies and prosthesis imbedding; by means of the results, the positioning sheet (in a single positioning type or a composite type) is determined and designed; a doctor logs into a data management module to query data. The single positioning type positioning sheet is formed by thickening and punching on an extraction face of the reconstructed model; the composite positioning sheet is a combination of the single positioning type positioning sheet and an osteotomy device, and the osteotomy positioning function is achieved. By means of the positioning sheet designed through an auxiliary system, the lower limb force line can be accurately reconstructed, and accurate osteotomies can be achieved; an informatization management method is provided by the data management module for operations, and convenience is brought to data storage and querying.

Systems, methods and computer-accessible media for acquiring and authenticating public key certificate status

Exemplary embodiments of systems, methods and computer-accessible medium can be provided for obtaining and verifying a public key certificate status. In particular, it is possible to construct and send a certificate query request, construct and send a combined certificate query request, construct and send a combined certificate status response, deliver a certificate status response, perform a verification by the general access point, and/or perform a verification by the user equipment. The exemplary embodiments address some of the deficiencies of conventional methods which have a complicated implementation as well as likely inability of such conventional methods to be applied to the network architecture of user equipment, a general access point and a server. The exemplary embodiments of the systems, methods and computer-accessible medium can obtain a user certificate status to provide certificate statuses of the user or the user equipment and the general access point when the user equipment accesses the network via the general access point. Message exchanges can be reduced, bandwidth and calculation resources can be saved, and higher efficiency can be achieved. According to another exemplary embodiment, by way of adding random numbers into the certificate query request and the combined certificate query request, as well as the message m, freshness of the certificate status response can be facilitated and even ensured, and security protection can be enhanced.

A quick selection method for macro block mode

The invention relates to a rapid selection method of macro-block mode during video information processing procedure, particularly a rapid selection method suitable for P-slice macro-block mode. The method comprises the following steps: step 1, determining the size of continuous macro-block according to the size of on-chip memory in the beginning, dividing all macro-blocks in one frame into a plurality of continuous 16is multiplied by16 macro-blocks, all macro-blocks in each continuous macro-block being positioned in the same row in the same one frame, and distributing the desired on-chip buffer zone; step 2, copying the brightness and colority data required for the mode selection of continuous macro-blocks in the current frame and the reference frame to the on-chip buffer zone; step 3, calculating the mode of each macro-block in the continuous macro-blocks to determine the final mode of each macro-block; and step 4, if all macro-blocks in the current continuous macro-block are processed, stopping the selection procedure of the current continuous macro-block, otherwise returning to the step 1 to continue. The inventive technical proposal can efficiently accelerate the speed of video compression and calculation, thereby realizing the real-time compression of video.

Intelligent composite type electrostatic fresh air purifier

The invention discloses an intelligent composite type electrostatic fresh air purifier. The intelligent composite type electrostatic fresh air purifier comprises a shell and a control system. A self-balancing type fresh air inlet is formed in an outdoor side plate of the shell. A flow equalizing air supply port is formed in an indoor side plate of the shell. A temperature and humidity sensor, an indoor particulate mass concentration sensor and a carbon dioxide concentration sensor are arranged at the flow equalizing air supply port in the shell. An outdoor particulate mass concentration sensor, an electrostatic filtering section, an antimicrobial electret filter, an activated carbon filter and a silent cross-flow fan are sequentially arranged from the self-balancing fresh air inlet to the flow equalizing air supply port in the shell. A corona wire and dust collection plates are arranged in the electrostatic filtering section and are connected with an adjustable direct-current power supply. According to the intelligent composite type electrostatic fresh air purifier, by means of the combination which can regulate the filtering efficiency and is composed of an electrostatic filter and a fiber filter, resistance of the whole filtering section is reduced under the condition of not sacrificing the filtering efficiency, and meanwhile the running efficiency of fresh air purification devices is improved.
