6results about How to "Improve scan accuracy" patented technology

The utility model relates to the field of coding detection, in particular to a carton coding detection device which comprises a bottom plate, a guide rail, a moving block, a hydraulic cylinder and a scanner, a conveying belt is arranged at the upper end of the bottom plate, the guide rail is arranged above the bottom plate, the moving block is arranged in the guide rail, and the hydraulic cylinder is arranged at the lower end of the moving block. A scanner is arranged at the lower end of the hydraulic cylinder, and rolling wheels with a locking effect are arranged at the upper end of the moving block. According to the device, the multi-angle accurate scanning effect is achieved in a mode of conveniently adjusting the scanning position, and the problems that the detection range is limited and detection of different coding positions cannot be flexibly changed due to the fact that an existing carton coding detection device lacks a plurality of effects of conveniently and rapidly adjusting detection are solved.

The invention relates to the technical field of answer sheet counting machines, and particularly discloses an answer sheet counting machine with high accuracy, which comprises two conveying racks and a conveying mechanism, the conveying mechanism is arranged between the two conveying racks, and the conveying mechanism is used for conveying answer sheets; the pressing mechanism is arranged at the top of the conveying frame, and the pressing mechanism is used for placing and pressing the answer sheet; the conveying mechanism is arranged, so that the answer sheets can be conveyed and moved gradually, and the answer sheets can be scanned and counted conveniently; by arranging the pressing mechanism and the progressive mechanism, the progressive mechanism can be driven under the condition that the conveying mechanism is controlled to operate, so that the progressive mechanism gradually descends to move and is matched with the pressing mechanism, the answer sheets can be progressively pressed one by one, and the phenomenon that the positions of the answer sheets are loosened when the answer sheets are conveyed one by one is prevented; therefore, a large number of answer sheets can be gathered together.

The utility model discloses a device of cooperation children anaesthetized under magnetic resonance examination relates to medical auxiliary technical field. Including split type mattress, this split type mattress is divided into the headrest area of supporting head portion and the main body support area of bearing body, and all are by the upper pad layer and lower pad layer of interconnection composition, head adjustment subassembly is set up above headrest area, is used for adjusting the head of patient is the head -up and holds the state of the chin. The utility model can promote the safety, accuracy and comfort of children nuclear magnetic resonance scanning examination.

The present invention relates to the field of three-dimensional data scanning, and in particular, to a three-dimensional scanning platform, system and method. The three-dimensional scanning platform includes a load-bearing light-transmitting plate for placing an object to be measured, a reflector arranged on the side of the load-bearing light-transmitting plate away from the object to be measured, and at least one positive reflective marking point and at least one negative reflective marking point arranged on the side of the load-bearing light-transmitting plate away from the object to be measured, wherein the reflective surface of the positive reflective marking point faces the side of the object to be measured, and the reflective surface of the negative reflective marking point faces the side away from the object to be measured. The three-dimensional scanning system of the present invention can generate an accurate and complete three-dimensional model of the object to be measured, making the data collection process of the object to be measured easier and the collected data more accurate; and the system has a simple structure, low cost, light weight, easy handling and carrying, flexible and convenient use, low maintenance cost, and is suitable for scenes of various spatial dimensions.

The invention discloses a security vulnerability scanning method and device, computer equipment and a storage medium. The method comprises the following steps: receiving and intercepting request data; analyzing and storing original normal request parameters of the request data; replacing the original normal request parameter with the security test pollution data with the pollution mark; continuing to process the request message according to the replaced request data; in a response stage after the request processing is completed, intercepting and analyzing response content; and executing security vulnerability detection and judgment based on the intercepted response content. According to the method, the request parameters are intercepted and modified, the request data are subjected to vulnerability scanning by using the security test pollution data with the pollution marks, and then the normal request parameters are replied, so that the problem of data pollution is avoided while the vulnerability scanning accuracy is improved.

The utility model provides a kind of RFID intelligent shelf, it is related to warehousing management technical field, including the shelf part being composed of several layers and left and right side support, and the antenna scanning part being set in one side of shelf part.Antenna scanning part includes support frame, X-axis drive mechanism, Y-axis drive mechanism, Z-axis drive mechanism, slide beam and antenna, in addition, still being equipped with control center, with X-axis power transmission source, Y-axis power transmission source, Z-axis drive mechanism, antenna electric connection, through X, Y, Z-axis drive mechanism, antenna can be driven along X-axis and Y-axis movement, Z column moves, realizes to the layer-by-layer scanning of shelf goods.This RFID intelligent shelf solves the problem that traditional shelf artificial management is complicated and easy to make mistake, and the problem that the scanning flexibility and accuracy of existing RFID intelligent shelf are insufficient, with the advantages of efficient scanning, stable structure, safety protection and convenient installation.
